TENSIONING THE BELT
Caution:
Over-tightening of
the roller will
severely shorten the
life of the belt and
may cause further
damage to other
components.
Running Belt:
If when you plant your foot on the belt, you can
feel a slipping sensation then the belt has stretched and
is slipping across the rollers. This is a normal and
common adjustment on a new treadmill. To
eliminate this slipping, tension both the rear rollers
Allen bolts 1/4 TURN as shown above. Try the
treadmill again to check for slipping. Repeat if
necessary, but
NEVER
TURN the
roller bolts
more than 1/4
turn at a time.
Drive Belt:
If you
have
tensioned the
running belt
and are still
experiencing
a slipping, adjust the tension screw. Then try the
treadmill again to check for slipping.
