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.
Order Adjustment Method Picture
1
First, loosen the motor bolts (marked Ain 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.
2
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.
4 Set motor speed to 1.8 MPH~2.1 MPH (2.5 KPH ~ 3.5 KPH)
to test belt tightness.

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.
6 Look here to determine whether the drive belt fails to engage
either the motor pulley or the front roller pulley.
