Maintenance and Tips

Belt Tensioning

If the belt begins to slip and needs to be tensioned, there are tension bolts
that are accessible from the back of the treadmill. Before tensioning the belt,
start the treadmill and set the speed to 3 mph (5 kph).
A. Using a 6 mm Allen wrench, included in your hardware bag, turn the
right and left tension bolts 1/2 turn clockwise.
B.
Test to see if the slipping is eliminated. If the belt slips repeat step A and
test again.
Note: Adjusting one side more than the other will cause the belt to
drift to the side of the treadmill and will require belt alignment. Check
to be sure the running belt is still aligned. If belt alignment is off as
shown below refer to Belt Alignment section.
CAUTION: DO NOT tighten more than 2 full turns on each side.
Over tensioning the belt can cause unnecessary friction and wear
and tear on the belt, motor and electronics.
Belt Alignment
A. Press Start, then increase the treadmill speed to 3 mph (5 kph).
B.
Stand at the rear of the treadmill to see which way the belt is drifting.
C. If the belt drifts to the left, turn the left adjustment bolt one-quarter
turn clockwise and the right adjustment bolt one-quarter turn counter-
clockwise. (See FIG. 1)
D. If the belt drifts to the right, turn the left adjustment bolt one-quarter
turn counter-clockwise and the right adjustment bolt one-quarter turn
clockwise. (See FIG. 2)
E.
Observe the tracking for two minutes. Repeat steps A-D as needed.
