Common Symptoms; Treadbelt Feels Like It’s Slipping Or Grabbing When Walked On; Treadmill Slows Down When User Steps Onto Treadbelt - Landice L Series Diagnostic And Service Manual

Symptom: Treadbelt feels like it's slipping or grabbing when walked on.
Possible Cause: Loose drive belt or treadbelt. Adjust as per manual. Remember to adjust only till
slipping stops. DO NOT OVERTIGHTEN
Possible Cause: Worn treadbelt and/or deck. If treadbelt or deck is worn it will cause excessive
friction and the user will feel like belt is slipping or grabbing.
1. Reach hand under front of treadbelt and see if deck feels rough, grooved, or if you see bare
wood. These are signs the belt needs to replaced and the deck needs to be reversed or
replaced if it has already been reversed.
2. Compare the outer edge of the treadbelt to the middle of the treadbelt. The outer edge wears
less since the user walks near the center of the belt. You will be able to see the cross weave of
fabric on a good treadbelt. This cross weave design traps air inside tiny pockets. The treadbelt
glides on this trapped air. When a belt wears, the cross weave becomes flat and smooth. This
is not good because there are no more pockets to catch the air. If the center of the treadbelt is
smooth (glazed) and exhibits black streaks it's time to replace.
3. If amp draw is high (8 amps or more on home) it is advisable to check belt and deck for
wear. Tip: If Red Current Lamp is lit then Amp Draw is high.
TREADBELTS AND DECK SURFACE SHOULD ALWAYS BE REPLACED TOGETHER IF
EITHER IS WORN OUT.
Symptom: Treadmill slows down when user steps onto treadbelt.
Possible Cause: Worn out treadbelt or deck. See above.
Possible Cause: Worn or defective motor brushes and/or scorched commutator on drive motor.
Dress out commutator and replace brushes.
Possible Cause: Demagnetized stator magnets on drive motor.
Make sure that treadmill is unplugged! Disconnect drive motor from lower circuit board. Hold
the two motor wires, Black A+ and White A-, together and rotate the motor flywheel by hand. Get a
good feel for the rotational friction of the drive motor. Then disconnect the two motor wires and
rotate the drive motor by hand. If the drive motor begins to spin much easier, then your motor is
not the problem. If you notice no difference, then replace the drive motor. NOTE: A good drive
motor will spin freely with little friction when disconnected from the lower circuit board. If the two
motor wires are connected together, the drive motor will become much harder to rotate. Also see:
