Walking belt misalignment Rear belt guides Belts should ride on top of triangular black belt guides
at rear of treadles.
Tracking adjustment Belts are not required to be perfectly centered and are
typically farther out in the rear than they are in the
front. This may vary depending on user’s stride. If belt
is tracking to one side far enough to cause rubbing
of belt, follow belt alignment procedure in Owner’s
Manual.

guides under Treadle can make a loud grinding sound.
If belts are misaligned, adjust walking belt.

Hesitation or belt slipping when walking on unit Walking belt tension Adjust walking belt tension at the front of the unit using
the provided hex wrench on the exposed adjustment
bolts located on each side of each front roller. Be sure
to adjust both bolts on each roller the same amount as

each adjustment bolt in full turn increments. After
each adjustment, restart unit and check to see if belt
slippage has been eliminated. Repeat if necessary. If
slipping feel persists after several adjustments, stop
and refer to drive belt checklist.
