Maintenance and Tips
Belt Tensioning
If the belt begins to slip and needs to be tensioned, tension bolts 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.
Turn both
Clockwise
to Tighten belt
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 behind the treadmill to see which way the belt is drifting.
C. If the belt drifts to the left, turn the left adjustment bolt 1/4 turn
clockwise and the right adjustment bolt 1/4 turn counter-clockwise.
(See FIG. 1)
D. If the belt drifts to the right, turn the left adjustment bolt 1/4 turn
counter-clockwise and the right adjustment bolt 1/4 turn clockwise.

Moving the Treadmill Base

unplugged from the wall.
2. Make sure nothing is on or near your treadmill which might spill, be
knocked off, or prevent the treadmill from moving.
3. Place both hands under the support bar located under the back of
the walking belt to make sure you have a solid lifting point.
4. Lift the back of the treadmill and roll to the desired location.
CAUTION: When lifting, use proper safety
precautions and lifting techniques. Bend
your knees and elbows, keep your back
straight and lift evenly
with both arms.
