via M17 wrench and remove it.


53

STEP 4:

Remove top bolt and screw

on the top incline motor via

17 wrench.

STEP 5:

Unplug the (Black, Red and

White) connector and black

wire on inverter and

(Green) wire on the frame.

STEP6:

Remove the inlcine motor

and replace the new inlcine

motor.


54

STEP7:

Plug the (Black, Red and

White) connector and black

wire into the inverter and

install the (Green) wire on the

frame.

Switch on the power, the

incline motor will be zeroed

automatically if its not at the

zero position. ( VR on incline =

0).

STEP8:

Install the incline motor and

reattach to secure the top bolt,

screw, and washers.(release

1/4 turn for better movement.)

STEP9:

The gap between Mainframe

and the Cushion on incline

motor will be 3mm to 5mm.

NOTE: If this step is not done,

the incline motor might get

jammed when it is powered on

by the inverter and console.

You may refer the following

figure taken from M8 treadmill

for reference.


55

STEP10:

Screw bottom bolt and screw on

threaded rod of incline motor via

M17 wrench to assemble.

Secure the Top bolt and screw

should be fully tightened.

STEP11:

Switch on the power, and raise

the incline level to remove the

support (sturdy objects).

Check no items on the treadmill

and press “STOP” to restore the

incline level.

Put the motor cover back and

secure 2 screws on motor cover

to assemble for complete.

6. MAINTENANCE

WARNING! Always unplug the power cord before cleaning, lubricating, or performing any

maintenance.

6.1 General Maintenance

The safety of the equipment can be maintained only if it is examined regularly for damage or wear. If

maintenance is required, keep the equipment out of use until defective parts are repaired or replaced.

The following preventive maintenance tips will keep the machine operating at peak performance:

• Locate in a cool, dry place.

• Keep the display console free of fingerprints and salt build-up caused by sweat.

• Long fingernails may damage or scratch the surface of the console; use the pad of the finger to

press the selection buttons on the console.

• Use a 100% cotton cloth, lightly moistened with water and a mild liquid cleaning product, to clean.

Other fabrics, including paper towels, may scratch the surface.

• Do NOT use ammonia or acid-based cleaners.

• Brush away any wax deposits from the deck and belt area.

6.2 Running belt and running deck lubrication

Regular maintenance is necessary for best performance and longer treadmill life. The maintenance

procedure will prevent premature wear of the running belt, running deck and drive motor system. It is

difficult to predict exactly when will need lubrication, we recommend the following schedule as a

guide to lubricate:

NOTE: Please contact your distributor for ordering lubricant.

USAGE PERIOD LUBRICATION

Light user Less than 3 hours / week Every 4 months

Medium user 3~5 hours / week Every 2 months

Heavy user More than 5 hours / week Every 1 months

6.3 How to spray silicone on deck

1). Find the silicone bottle (Fig 5.3-1). It put into hardware kit package when you purchase this

treadmill, and open the carton box.

2). Spray silicone on treadmill deck evenly, the spray area is like the drawing showing. (Fig 5.3-2)

IMPORTANT! You must stop the treadmill belt completely before spraying the silicone. Failure to do

so could cause injury such as cutting your hand on the edge of the belt and crushing your fingers

between the rear roller and the belt. Do NOT spray too much silicone on the deck. It can cause the

running belt to slip when in use if there is too much lubrication.

WARNING! The running belt should be centered and adjusted within the area which has been

indicated by the arrows on right roller cover and left roller cover. The running belt could be worn or

damaged if the running belt travels beyond this scope. The running belt travel area is showing below:

Running belt/deck is worn: It will cause the motor current (input current) to be too high, it’s probably

in a long term of Moderate wear or Need exchange status so that it causes the temperature to

become too high, should you replace running belt/deck and properly add lubricating system), check

the input current status; Motor current (output current) should be at the value as below, user weight is

6.6 Troubleshooting the Treadmill

SYMPTOM CAUSE SOLUTION

Console display does not illuminate.

A).No power to treadmill. B).Console wire is not connected
