GENERAL SAFETY WARNING DESCRIPTION – CONTINUED
WARNING
CARBON MONOXIDE (EXHAUST GASES) CAN KILL!!! 0000
• Carbon monoxide is a colorless, odorless, deadly poison which, when breathed, deprives the body of
oxygen and causes suffocation. Exposure to air containing carbon monoxide produces symptoms of
headache, dizziness, loss of muscular control, apparent drowsiness, and coma. Permanent brain
damage or death can result from severe exposure.
• Carbon monoxide occurs in the exhaust fumes of internal combustion engines. Carbon monoxide
can become dangerously concentrated under conditions of inadequate ventilation. The following
precautions must be observed to ensure safety of personnel when the engine of the 120M Motor
Grader is operated.
– DO NOT operate engine in enclosed areas.
– DO NOT idle engine without adequate ventilation.
– BE ALERT for exhaust poisoning symptoms. They are:
• Headache
• Dizziness
• Sleepiness
• Loss of muscular control
– If you see another person with exhaust poisoning symptoms:
• Remove person from area.
• Expose to fresh air.
• Keep person warm.
• DO NOT permit physical exercise.
• Administer Cardiopulmonary Resuscitation (CPR) if necessary.
• Notify a medic.
– BE AWARE. The field protective mask for Chemical, Biological, Radiological, andNuclear (CBRN) protection will not protect you from carbon monoxide poisoning.
– CALIFORNIA PROPOSITION 65 WARNING: Engine exhaust and some of its
constituents are known to the State of California to cause cancer, birth defects,
and other reproductive harm.
THE BEST DEFENSE AGAINST CARBON MONOXIDE POISONING IS GOOD VENTILATION!

1. CPC of Army materiel is a continuing concern. It is important that any corrosion problems with this item bereported so that the problem can be corrected and improvements can be made to prevent the problem in future
items.
2. Corrosion specifically occurs with metals. It is an electrochemical process that causes the degradation of
metals. It is commonly caused by exposure to moisture, acids, bases, or salts. An example is the rusting of
iron. Corrosion damage in metals can be seen, depending on the metal, as tarnishing, pitting, fogging, surface
residue, and/or cracking.
3. Plastics, composites, and rubbers can also degrade. Degradation is caused by thermal (heat), oxidation
(oxygen), solvation (solvents), or photolytic (light, typically UV) processes. The most common exposures are
excessive heat or light. Damage from these processes will appear as cracking, softening, swelling, and/or
breaking.
4. SF Form 368, Product Quality Deficiency Report should be submitted to the address specified in DA PAM
750-8, TAMMS Users Manual.
OZONE DEPLETING SUBSTANCES 0000 00
There are no ozone depleting substances contained on the machine or used during machine maintenance.

ENGINE 0003
1. General. The grader is equipped with a Caterpillar C6.6 Acert VHP turbocharged diesel engine with six in-line
cylinders, generating 153 horsepower @ 2,000 RPM.
2. Fuel System. Diesel fuel is drawn from the tank by a fuel transfer pump, filtered by a primary fuel filter, routed
to the fuel injection pump and secondary filter, and then injected through the fuel injector nozzles into the
engine cylinders. Air is drawn in through dry-type, replaceable filter elements. A check valve removes incoming
dust from the air and routes it out through the exhaust system. The air is routed from the filter assembly to the
turbocharger which pressurizes the air and sends it to the air-to-air aftercooler. The aftercooler, located near
the radiator, reduces the air temperature making it denser. The denser air charge allows for more air and fuel
to be combusted per engine cycle, increasing engine output power.
3. Cooling System. Provides coolant to the engine. Coolant is circulated through the engine by a gear-driven
water pump. The hydraulic oil cooler is located in front of the radiator. The engine oil cooler is integral to the
engine. The transmission oil cooler is located behind an access cover below the left front access door.
4. Lubrication System. The engine lubrication system consists of a gear-driven oil pump, oil fi lter, oil cooler, and
oil pan. The engine is lubricated by cooled and pressurized oil that is circulated through the engine block and
head.
5. Exhaust System. The exhaust system removes exhaust gases from the engine through the exhaust manifold
and turbocharger. The gases flow into exhaust pipes and a muffler to the atmosphere behind the cab.

POWERTRAIN 0003
1. Transmission. Eight speeds are provided in forward and six in reverse. A transmission modulator control
(inching pedal) disengages the transmission from the drive wheels. Inching allows the operator to vary the
machine ground speed while keeping engine speed high for quick implement response.
2. Rear Axle Differential and Lock Differential. A four-wheeled tandem rear axle arrangement houses axle
shafts driven by a lock-unlock equipped differential. The axle shafts turn the final drive sprocket chains through
planetary reduction gears. The sprocket chains then drive the final drive sprockets.
3. Final Drive Assembly. The sprocket chains drive the final drive sprockets and axle shafts which turn the rear
wheel spindles inside the tandem axle housing.

BRAKES 0003
1. General. The oil-bathed, multiple-disc service brakes are hydraulically activated. Each tandem wheel end
contains a service brake unit. A brake wear indicator is easily accessible for checking brake wear. A
compensator maintains consistent brake performance.
2. Service Brakes. A foot pedal is used for engaging multiple disc brake assemblies for each wheel within the
tandem and spindle housings.
3. Parking Brakes. Multiple oil-bathed disc-type located in the transmission case. Electrically actuated by an
ON/OFF switch on the right side of the instrument panel, the parking brake is spring applied and hydraulically
released. The parking brake is integrated into the Operator Presence System to prevent unintended machine
movement while the operator is not in the cab seat.
4. Brake Accumulators. Two brake accumulators, located behind the cab, assist in applying the service brakes.
The accumulator remains charged even after the engine is shut down and provides limited braking ability.

ELECTRICAL 0003
1. The electrical system, interruptible by a lockable battery disconnect switch, consists of two 12V batteries con-
nected in series with negative grounding, providing 24V to operate the electrical systems and components.
2. The system contains all the necessary switches, circuit breakers, fuses, relays, harnesses, and connectors to
operate the machine, including a NATO slave receptacle.
3. The major systems comprising the electrical system are:a. Starting system.
b. Charging systems.
c. Messenger display system.
d. Service, work, and blackout lights.
HYDRAULICS 0003
1. General. The hydraulic system is comprised of a single fluid tank, an implement and steering pump, a brake
and hydraulic fan pump, a secondary steering pump, and a set of bank valves to distribute hydraulic fluid
pressure to the various hydraulically activated systems (braking, steering, articulation, wheel lean, and earth
moving components). The system also contains various control valves, check valves, sensors, and
accumulators to maintain correct pressures. The fluid tank with a sight glass to check fluid level is located
behind the left rear access door. A hydraulic fluid cooler is located in front of the radiator.
2. Steering System. The steering system utilizes hydraulic pressure produced by the implement and steering
pump to actuate steering cylinders. An electric secondary hydraulic steering pump, located below the cab,
provides hydraulic steering pressure in the event of implement and steering pump failure.
3. Steering Cylinders. There are two steering cylinders mounted at the front axle that turn the front wheels. The
cylinders are powered by the hydraulic system and controlled by the steering pump and joystick controls.
4. Wheel Lean Cylinder . The wheel lean cylinder is mounted on the right side of the front axle. It is powered by
the hydraulic system and controlled by a switch on the left joystick. The function of the wheel lean cylinder is to
set the front wheels at an angle. This counteracts blade pressure exerted sideways against the front wheels
when grading or moving heavy material. The wheel lean cylinder also sets front wheel angle to prevent the
front of the machine from slipping sideways and downward when the machine is moving across a slope.
5. Ground Engagement Tools. The scarifier height, blade height, rotation, tilt, sideshift, centershift, and angleare all hydraulically powered and controlled using joysticks and joystick controls.
6. Brake System. The service brakes are hydraulically activated by pressing down on the foot pedal in the cab.
Hydraulic pressure is provided by the engine driven fan and brake pump located behind the left front access
door. The parking brake is spring actuated and hydraulically released via a switch located on the right side of
the instrument panel activated by the operator.
7. All-Wheel Drive (AWD). All-wheel drive provides machine propulsion to the front tires when commanded by
the operator. The AWD control is located on the right-side control panel. All-wheel drive can be operated in
either CREEP or MANUAL mode by providing hydraulic fluid pressure to hydraulic motors at the front wheels.
When in CREEP mode, the machine is propelled only by the front wheels. Speed in CREEP mode is variable
from 0 to 5 mph (0 to 8 km/h). In MANUAL mode, the front wheels can be commanded to run at 99 percent,
100 percent, or 120 percent of rear wheel speed.

WARNING
• CARBON MONOXIDE (EXHAUST GASES) CAN KILL!
• Carbon monoxide is a colorless, odorless, deadly poison which, when breathed, deprives
the body of oxygen and causes suffocation. Exposure to air containing carbon monoxide
produces symptoms of headache, dizziness, loss of muscular control, apparent
drowsiness, and coma. Permanent brain damage or death can result from severe
exposure.
• Carbon monoxide occurs in the exhaust fumes of internal combustion engines. Carbon
monoxide can become dangerously concentrated under conditions of inadequate
ventilation. The following precautions must be observed to ensure safety of personnel
when the engine of the 120M Grader is operated.
• DO NOT operate engine in enclosed areas.
• DO NOT idle engine without adequate ventilation.• BE ALERT for exhaust poisoning symptoms. They are:
• Headache
• Dizziness
• Sleepiness
• Loss of muscular control
• If you see another person with exhaust poisoning symptoms:
• Remove person from area.
• Expose to fresh air.
• Keep person warm.
• DO NOT permit physical exercise.
• Administer Cardiopulmonary Resuscitation (CPR) if necessary.
• Notify a medic.
• BE AWARE. The field protective mask for Chemical, Biological, Radiological, Nuclear
(CBRN) protection will not protect you from carbon monoxide poisoning.
• CALIFORNIA PROPOSITION 65 WARNING: Engine exhaust and some of its constituents
are known to the State of California to cause cancer, birth defects, and other reproductive
harm.
The Best Defense Against Carbon Monoxide Poisoning Is Good Ventilation !

Moving Machine from NEUTRAL Using Automodulation 0005
CAUTION
• Avoid automodulation while machine is under load.
• Selecting forward gears six through eight or reverse gears five or six isNOT recommended.
• Failure to follow these cautions may result in damage to equipment.
NOTE
• Forward gears one through five and reverse gears one through four are recommended for
automodulation.
• Do not change engine speed while automodulating. Harsh shifting will result.
Automodulation entails shifting into forward or reverse gear by moving transmission control switch from NEUTRAL
position to either FORWARD or REVERSE position (Figure 10). Transmission initial gear will engage smoothly via
direction clutch. If initial gear is not desired, use upshift or downshift switch to select desired gear.

Sequential Speed Shifting 0005
Sequential speed shifting allows the operator to change transmission gears while the machine is in motion. Activat-
ing Upshift and Downshift switches as desired will result in obtaining optimum ground speed for the operation
being performed (Figure 12). Speed shifting can be performed at any loading as shifts are automatically compen-
sated based on engine load.Upshifts can occur at any engine speed but should be matched to load. Several shifts can be commanded at one
time, although there is a delay between shifts.
Downshifting requires engine speed to be less than full throttle to prevent engine overspeeding. Downshift control
requests are computer controlled. If engine speed is too high, engine speed is reduced to allow downshift to occur.
Upon shift completion, throttle control is returned to the operator.

Programmable Transmission Initial Gear Setting 0005
The initial gear is the gear that engages when the transmission control switch is engaged in FORWARD or
REVERSE position without selecting a specific gear. Each direction can have only one initial gear, and each direc-
tion can use different initial gears. Initial gears can be the same as but not higher than what is set as maximum
gear. Initial gear setting can be changed using the Messenger system when transmission is in NEUTRAL and themachine is stopped. Changes made are new defaults at time of change or after a power cycle.
Programmable Transmission Maximum Gear Setting 0005
The maximum gear is the highest gear the transmission will shift into. Each direction can have only one maximumgear, and each direction can use different maximum gears. For FORWARD position, gears 3 through 8 are avail-able. In REVERSE Position, gears 3 through 6 are available. Initial gear setting can be changed using ElectronicTechnician when transmission is in NEUTRAL and the machine is stopped. Changes made are new defaults attime of change or after a power cycle
Transmission Modulator Control (inching pedal) 0005
The transmission modulator control (inching pedal) disengages power to the wheels. Press pedal in order todecrease power to the wheels. A sensor monitors pedal position and varies hydraulic pressure to directionclutches. When the pedal is fully depressed, power to the wheels will be disengaged.
The inching pedal can be used in all load conditions and provides the operator with speed control between two dis-tinct gears. This is useful when the operator demands high engine speed for quick implement control while varyingground speed.
CAUTION
• Avoid prolonged use of the inching pedal when moving heavy loads. Shift into lower gear to match load condition. Failure to follow this caution may result in equipment damage.
• Do not use inching pedal as a clutch for directional changes. Machine is designed to“shuttle shift”. Failure to follow this caution may result in equipment damage.
If the inching function is used in high load conditions, the operator should shift into a gear matched for that loadcondition. If constant stalling occurs, downshifting is advisable.

ALL-WHEEL DRIVE (AWD) 0005
All-wheel drive (AWD) allows the operator to choose which wheels propel the machine and how fast the front
wheels turn in relation to the rear wheels. All-Wheel Drive is controlled by an AWD Mode Switch (CREEP {turtle},
OFF {circle}, and MANUAL {hand} positions) and an AWD Control Dial (minus, circle, and plus signs) (Figure 18).
• With AWD off, only tandem wheels propel the machine. Machine speed is controlled by the accelerator
pedal.
• When AWD is activated and CREEP mode engaged, only the front tires propel the machine. Front wheel
speed (zero to 5 mph {8km/h}) is controlled by the AWD Control Dial. Creep mode provides very precise
speed control when fine blading around obstacles, and prevents rear wheels from damaging finished sur-
faces due to driving force of rear wheels.
• When AWD is activated and MANUAL mode engaged, all six wheels propel the machine. Front wheel
speed (98 to 120 percent of rear wheel speed) is controlled by the AWD Control Dial. The center detent is
100% or 1:1 front wheel speed to rear wheel speed. Higher aggression (101% to 120%) allows more
power to be transmitted through the front wheels, providing better steering control in low traction conditions
and when bank sloping when trying to keep front wheels on slope while rear wheels are on level ground.
Figure 18. All-Wheel Drive Controls. 005

SCARIFIER OPERATION 0005
The scarifier, made of up to 11 shanks with teeth, is used to break up hard ground or material to a regulated depth
to make it ready to grade. The number of shanks/teeth used depends on the consistency of the material being bro-
ken up.
The center five shanks (with teeth) may be removed to allow scarifier assembly to be raised to gain additional
ground clearance when necessary. The remaining shanks can be stowed upside down in the scarifier frame, if
additional clearance is required. Up to five removed scarifier shanks may be stored in the scarifier shank stowage
rack located at the front of the machine. A strap is provided to bind shanks together to avoid loss. Stow shanks in
rack facing every other one backwards to allow stowage of up to five shanks. Refer to Scarifier Tooth and Shank
Maintenance (WP 0027).
Scarifier digging angle can be adjusted to accommodate different needs. Notify Field Level Maintenance if scarifier
digging angle adjustment is required.

0 0 1 2 PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) INTRODUCTION
GENERAL00012
1. To ensure that the 120M Motor Grader is ready for operation at all times, it must be inspected on a regular
basis so that defects may be found and corrected before they result in injury, damage, or equipment failure.
2. The PMCS Table in WP 0013 contains systematic instructions on inspections, lubrications, services, tests, and
corrections to be performed by the operator to keep the equipment in good operating condition and ready for
its primary mission.
EXPLANATION OF TABLE ENTRIES 00012
1. Item No. Column. Numbers in this column are for reference. When completing DA Form 2404 or DA Form
5988-E, Equipment Inspection and Maintenance Worksheet, include the item number for the check/service
indicating a fault. Item numbers also appear in the order that you must perform checks and services for the
interval listed.
2. Interval Column. This column tells you when you must perform the procedure in the Procedure column:
a. Before procedures must be done immediately before you operate the grader.
b. During procedures must be done while you are operating the grader.
c. After procedures must be done immediately after you have operated the grader.
d. Biweekly or Every 100 Service Hours procedures must be done once every two weeks or after every
100 hours of machine operation.
e. Initial 500 Service Hours (or at first oil change) procedures must be done after the first 500 hours of
machine operation or at the first engine oil change.
f. Every 500 Service Hours or 3 Months procedures must be done every 500 hours of machine operation or
every three months.
g. Every 1,000 Service Hours or 6 Months procedures must be done every 1,000 hours of machine operationor every six months.
h. Every 2,000 Service Hours or 2 Years procedures must be done every 2,000 hours of machine operation
or every two years.
i. Yearly procedures must be done once each year.
3. Item to Check/Service Column. This column lists the item to be checked or serviced.
NOTE
The WARNINGs and CAUTIONs appearing in your PMCS table should always be
observed. WARNINGs and CAUTIONs appear before applicable procedures. You must
observe these WARNINGs to prevent injury or death to yourself and others, and
CAUTIONs to prevent your equipment from being damaged.4. Procedure Column. This column gives the procedure you must perform to check or service the item listed in
the Item to Check/Service column, to know if the equipment is ready and available for its intended mission. You
must perform the procedure at the time stated in the Interval column.
5. Not Fully Mission Capable If: Column. Information in this column tells you what faults will keep your equip-
ment from being capable of performing its primary mission. If you perform check/service procedures that show
faults listed in this column, the equipment is not mission-capable. Follow standard operating procedures for
maintaining the equipment or reporting equipment failure.

GENERAL PMCS PROCEDURES 00012
1. Intervals (on-condition or hardtime) and the related manhour times are based on normal operation. The
manhour time specified is the time you need to do all the services prescribed for a particular interval. Change
the hardtime interval if your lubricants are contaminated or if you are operating the equipment under adverse
operating conditions, including longer-than-usual operating hours. The hardtime interval may be extended
during periods of low activity. If extended, adequate preservation precautions must be taken.
2. Always perform PMCS in the same order so it gets to be a habit. Once you have had some practice, you will
spot anything wrong in a hurry. If the equipment does not perform as required, refer to the appropriate trouble-
shooting procedure in Chapter 3.
3. If anything looks wrong and you cannot fix it, write it on your DA Form 2404 or DA Form 5988-E. If you find
something seriously wrong, IMMEDIATELY report it to your supervisor.
4. Before performing preventive maintenance, read all the checks required for the applicable interval and prepare
all that is needed to make all the checks. You will always need a rag (Item 17, WP 0032) or two.
WARNING
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and
low toxic material. However, it may be irritating to the eyes and skin. Use protective gloves
and goggles. Use in well-ventilated areas. Keep away from open flames and other
sources of ignition. Failure to follow this warning may result in injury or death to personnel.
CAUTION
Be especially careful when cleaning electrical system components including lighting.
Damage or impaired operation could result if this caution is not observed.
a. Keep Equipment Clean. Dirt, grease, oil, and debris get in the way and may cover up a serious problem.
Clean as you work and as needed. Use solvent cleaning compound (Item 2, WP 0032) on all metal
surfaces. Use detergent (Item 4, WP 0032) and water when you clean rubber, plastic, and painted
surfaces. Spot paint as required to prevent corrosion.
b. Bolts, Nuts, and Screws. Ensure that they are not loose, missing, bent, or broken. Report loose, missing,
or damaged bolts, nuts, and screws to your supervisor.
c. Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. Report bad welds to
your supervisor.
d. Electrical Wires and Connectors. Look for cracked or broken insulation, bare wires, and loose or broken
connectors. Report loose connections and faulty wiring to your supervisor.
e. Hoses, Lines, and Fittings. Look for wear and damage. Check for loose clamps and fittings. Report any
worn, damaged, or loose hoses, lines, and fittings to your supervisor.

Direct airflow from inside element and up and down pleats rather than across pleats.
2. With assistance from Field Level Maintenance personnel, clean primary element.
3. Inspect primary element for tears, holes, damaged pleats, gaskets, or seals. Discard if damaged.
4. Inspect element using a work light. Light should be visible through the element when light is placed inside ele-
ment. If necessary, compare to a new element to confirm results.
CAUTION
Do not remove secondary air filter element until you have the new element ready to install.
This will reduce the possibility of dirt entering the engine. Failure to follow this caution may
result in damage to equipment.
