IMPORTANT INFORMATION FOR MACHINES WITH SERIALNUMBER DATE CODES PRIOR TO DC1006 (October, 2006)Potential rolling hazard may exist when transporting the machine on a ramp or incline with keyturned to the “off” position. The machine could roll at an undesirable speed creating the risk forpotential injury or property damage.
To ensure operator safety and to prevent potential property damage,Tennant Company mandatesthat the existing control box assembly be replaced with the Control Box Kit (p/n 9003250). For moreinformation, refer to Technical Service Bulletin # 130. To determine if the machine in question hasbeen updated with the new Control Box Kit, refer to the picture below.
CONTROL BOX ASSEMBLY
If the Brake Relay (CR2) is present in theControl Box, the machine has already beenupdated and no further action is required.If the Brake Relay (CR2) is NOT present inthe Control Box, follow the instructions inTechnical Service Bulletin # 130.

CHARGING BATTERIES
ATTENTION: To prolong the life of the batteriesonly recharge the batteries if the machine wasused for a total of 30 minutes or more. Do not leavebatteries discharged for lengthy periods.
WARNING: Fire Or Explosion Hazard.Batteries Emit Hydrogen Gas. Keep Sparks AndOpen Flame Away. Keep Battery CompartmentOpen When Charging.
FOR SAFETY: When servicing batteries, wearprotective gloves and eye protection whenhandling batteries and battery cables. Avoidcontact with battery acid.
BATTERY CHARGER SPECIFICATIONS:
S CHARGER TYPE:-- FOR SEALED (Gel) BATTERIES-- FOR WET (Lead acid) BATTERIES
S OUTPUT VOLTAGE - 24 VOLTS
S OUTPUT CURRENT - 20 AMPS
S AUTOMATIC SHUTOFF CIRCUIT
S FOR DEEP CYCLE BATTERY CHARGING
ON--BOARD BATTERY CHARGER SETTINGS:
If your machine is equipped with the on--board charger,the charger settings must be set for your battery typebefore charging. Failure to properly set will result inbattery damage.
To determine your battery type, see battery label.Contact your battery supplier if not specified.
To verify what the charger is currently for, connect thecharger cord into an electrical receptacle. The chargerwill display a sequence of codes. One of the codes willeither read “GEL” or “Acd” (Figure 40).
GEL = Set for sealed/maintenance free batteriesAcd = Set for wet/lead acid batteries
FIG. 40
To change the setting, unplug the charger, peel up thecorner of the display label and set the switchesaccordingly (Fig. 41). The charger cord must beunplugged when resetting.
FIG. 41
USING THE ON--BOARD BATTERY CHARGER
IMPORTANT: Before charging, make sure that thecharger setting is properly set for your battery type(See ON--BOARD CHARGER SETTINGS).
1. Transport the machine to a well--ventilated area.
2. Park the machine on a flat, dry surface. Turn thekey off and set the parking brake, if equipped.
3. If charging wet (lead acid) batteries check the fluidlevel before charging (See BATTERYMAINTENANCE).
4. Prop up the recovery tank for ventilation(Figure 42).
FIG. 42
5. Connect the charger’s AC power supply cord into aproperly grounded receptacle (Figure 43).
NOTE: The machine will not operate when charging.

6. The charger will display a sequence of codes oncethe cord is connected (Figure 44).Three--digits + the following code:
A = Charging currentU = Battery Voltageh = Charging timeC = Charging ampere--hours [Ah]E = Energy used [Kwh]“GEL” or “Acd” = Battery type the charger iscurrently set for. Before charging make sureyour battery type matches the display:GEL=Sealed, Acd=WET (lead acid). To changesetting, see ON--BOARD CHARGERSETTINGS.
Press the arrow button to review the codes.
FIG. 44
7. Once the charging cycle begins, the indicator lightswill progress from red, yellow to green. When thegreen indicator light comes on, the charging cycleis done. Unplug the charger cord.
If the charger detects a problem, the charger willdisplay an error code (See ON--BOARD BATTERYCHARGER ERROR CODES).
USING AN OFF--BOARD BATTERY CHARGER(OPTION)
1. Transport the machine to a well--ventilated area.
2. Park the machine on a flat, dry surface. Turn thekey off and set the parking brake, if equipped.
3. If charging wet (lead acid) batteries, check the fluidlevel before charging (See BATTERYMAINTENANCE).
4. Prop up the recovery tank for ventilation(Figure 45).
FIG. 45
5. Connect the charger’s DC cord into the machine’sbattery receptacle (Figure 46).
6. Connect the charger’s AC power supply cord into aproperly grounded receptacle (Figure 46).
FIG. 46
7. The supplied charger will automatically begincharging and shut off when fully charged.
NOTE: The machine will not operate when charging.
ATTENTION: Do not disconnect the charger’s DCcord from the machine’s receptacle when thecharger is operating. Arcing may result. If thecharger must be interrupted during charging,disconnect the AC power supply cord first.

2. Load the machine using a ramp that can supportthe machine weight and person loading it. Themaximum ramp incline should not exceed 11 at aramp length of 3.7m (12 ft).
3. Position the front of machine up against the front ofthe trailer or truck. Lower the scrub head andsqueegee.
4. Set the parking brake, if equipped, and place ablock behind each wheel to prevent the machinefrom rolling.
5. Secure with tie--down straps as shown (Figure 85).It may be necessary to install tie-down brackets totrailer or truck.
FOR SAFETY: When loading/unloading machineonto/off truck or trailer, use a ramp that cansupport the machine weight and person loading it,do not exceed a 11 ramp incline at a ramp lengthof 3.7m (12 ft), use tie--down straps to securemachine and block machine wheels.
FIG. 85
STORING MACHINE
1. Charge the batteries before storing machine toprolong the life of the batteries.
2. Drain and rinse the tanks thoroughly.
3. Store the machine in a dry area with the squeegeeand scrub head in the up position.
4. Open the recovery tank cover to promote aircirculation.
ATTENTION: Do not expose machine to rain, storeindoors.
5. If storing machine in freezing temperatures, makesure to drain machine of all water.
For models equipped with the FaST System, followthe FaST SYSTEM FREEZE PROTECTIONprocedure below.
FaST SYSTEM FREEZE PROTECTION
Valve Coupling #1002856 and 15 cm Hose #63182 arerequired (Purchased separately).
1. Remove the FaST--PAK carton and connect thevalve coupling and 15cm hose (purchased parts) tothe supply hose (Figure 86).

2. Disconnect the opposite end of the supply hosefrom the injector assembly and drain the supplyhose (Figure 87). To access the injector assemblyremove the front shroud.
FIG. 87
3. Reconnect the supply hose to injector assemblyand pour a recreational vehicle (RV) anti--freezeinto the supply hose until full (Figure 88).
FIG. 88
4. Operate the FaST system as normal until thefoaming stops. This step could take anywhere from5--10 minutes.
5. Remove the valve coupling and connect thestorage plug (Figure 89).
FIG. 89
6. Drain the recovery and solution tanks and storemachine.
7. To drain the anti--freeze, repeat the drainingprocess above and reconnect the supply hose tothe FaST--PAK carton.
