Treadbelt Tracking Adjustment; Treadbelt Tensioning - Landice 90 Series Owner's Manual

Maintenance and Troubleshooting

5.2.2. Treadbelt Tracking Adjustment

Note: On the L7 model you should see an equal gap on either
side of the treadbelt. On L8 models, a yellow warning label
is visible on the deck from the rear of the treadmill when
the treadbelt is not tracked correctly.
The treadbelt is tracked by means of the two 9/16" hex head
bolts at the rear of the treadmill. Tightening (clockwise) the bolt
on the side of the treadmill that the belt has moved towards and
loosening the bolt on the opposite side an equal amount, will
cause the belt to move toward the center. Adjustments should
be made in ¼-turn increments, with the treadmill running at
2 to 3 mph. Allow at least 30 seconds for the belt to stabilize
between each adjustment. To ensure proper belt tracking and
alignment, the treadmill must be placed on a stable and level
surface.

5.2.3. Treadbelt Tensioning

The treadbelt is tensioned at the factory but may require
adjustment after installation. Need for tensioning is indicated by
uneven belt speed and may be felt as sudden stopping of the
treadbelt when your foot comes down on the belt.
To check belt tension: run treadmill at 1 mph, then walk on it. If
the belt does not feel like it is slipping or hesitating, then the
belt is tensioned correctly. If the belt slips/hesitates, then it is
not fully tensioned.
The same hex head bolts used for tracking also tension the
treadbelt. To tighten the treadbelt, turn both bolts clockwise
exactly the same amount, ¼-turn at a time. Failure to turn them
equally will affect belt tracking. DO NOT OVER-TIGHTEN.
Continue checking for treadbelt slipping. When treadbelt is fully
tensioned, speed up treadmill to 5 mph. Then, while jogging
lightly, check for any sudden slipping/hesitating of the treadbelt.
Repeat treadbelt tensioning if required.
