Also use a dry cloth for the areas that you can't reach with the vacuum cleaner. If the machine
has not been used for some time or is excessively dirty, use a dry cloth to wipe all exposed
areas. Replace the cover and screws when finished.
Four Times Per Year — Clean the belt and the deck surfaces to minimize the effect of
friction between the wood deck and the running belt. Clean the underside of the running belt
and the top of the running deck surface by wiping them with a clean dry towel. This should be
done four times per year to prevent premature wear of the deck, running belt, and the drive
motor system.
As Needed — The running belt may become loose and slip on the drive roller with each foot
plant.
To Re-tension the Belt: While holding down any key on the console, turn the treadmill on;
this brings you into Test Mode. Press Speed to increase the belt speed to 5 mph (8 kph).
Rotate both of the rear roller tension bolts 1/4 of a turn clockwise. If the belt tracks off center,
to either side, the running deck will become visible. If this occurs, it will be necessary to
adjust the running belt back to the center. See Figure 1.
! CAUTION: Be careful not to over tighten the belt. Over tightening the belt can
create excessive tension on the front and rear rollers.
To Re-center the Belt: Use a wrench to tighten the rear roller bolt on the side of the treadmill
towards which the belt is moving. For example: If the belt moves to the right and the deck
becomes exposed on the left, use a wrench to tighten the rear roller bolt on the right side of
the frame, tighten about 1/2 of a turn (clockwise) and wait 30 seconds. If the belt does not
move back to the center of the treadmill, make another adjustment to the same bolt. Once the
running belt has been adjusted closer to the center of the treadmill use about 1/4 of a turn
until the belt has been stabilized.
! CAUTION: While centering the belt choose one bolt to adjust. Do not adjust
both bolts.
After the belt has been centered, check the belt tension. Make sure the running belt tension is
tight enough so that the belt does not slip or hesitate when stepped on. Walk on the treadmill at
3.5-4 mph (5.6-6.4 kph) and every 4th to 5th step throw your weight into your step to feel if the
