Adjusting the Drive Belt
Problem: Drive belt spins without engaging the front roller. (Drive belt is too loose.)
Follow instruction below to adjust the drive belt.

Adjustment Method
Picture
First, loosen the motor bolts (marked A in the picture to the
right) but leave them in place. Do not loosen all the way.

Note: Use a socket wrench or a T-head wrench. Bolt size: 12
mm.

Push the motor back as indicated. This tightens the drive
belt.

Note: At this stage, do not secure the motor bolts. Leave
them in place but do not tighten them down.

Loosen the nut marked B in the picture to the right.
Tighten the bolt marked A so the drive belt can be pressed
down about one inch and twisted at the side to 90 degrees.
Note:
(1) Bolt A size: 10 mm.
(2) Use 10-mm open wrench. Crescent wrenches tend
to strip the bolt head.
Set motor speed to 1.8 MPH~2.1 MPH (2.5 KPH ~ 3.5 KPH)
to test belt tightness.

Adjustment Procedure
Picture
Use your foot to bear against the treadmill walk belt briefly.
Inspect whether the drive belt fails to engage either the front
roller or the drive motor pulley. If the walk belt spins freely in
either place, it’s too loose. See below.
Look here to determine whether the drive belt fails to engage
either the motor pulley or the front roller pulley.

If the drive belt is too loose, tighten screw A as shown in step
3. Inspect as shown in steps 4~6 until the proper belt
tightness is obtained.
When finished making adjustments, tighten nut B down
against the bracket as shown. Finally, tighten motor bolts
securely.
Inspect operation. Sometimes tightening the motor bolts
makes the drive belt too tight.
8
If the drive belt is too tight, there will be too much pressure
on the motor and roller bearings. Even the motor axle has
been reported to break if the belt is tightened too tight. Avoid
over-tightening the drive belt.

Adjusting the Walk Belt
Problem: The walk belt stops moving if you bear down against it. (Walk belt is too loose.)
Adjustment Procedure
Step
Method
1
Set the walk belt in the middle of the deck. (See Centering the Walk Belt.)
Tighten both sides of the walk belt equally (Figure 1). (Turn the T-shaped Allen wrench to the right to tighten or to
2
the left to loosen.) It’s better to have the belt too loose, rather than too tight. Inspect after each quarter turn to avoid
over-tightening the belt.
3
Turn unit speed to 2.5 KPH~3.0 KPH, 1.5 MPH~2.0 MPH. Walk on the treadmill.
Bear down against the belt (Figure 2). Make sure that bearing down against the belt does not make the walk belt
4
stop for more than about 3/4 second. (A loose walk belt will stop rotating when you put your weight against it.)
Tighten the belt just to the point where the walk belt free-spins momentarily and quickly regains traction.
Inspect walk belt tightness. Lift both sides; the distance from the middle of the belt to the deck should be 1 to 1.5
5
inches (2.54 to 3.81 cm) (Figure 3). Do not tighten beyond this point.
6
Repeat steps 2~5 if necessary, until the walk belt is adjusted properly.
