TEST PROCEDURES
DRIVE MOTOR TEST
This test is used in conditions of No Belt Movement.
Unplug treadmill and set voltmeter to volts DC Disconnect motor leads from PWM
Place 1 voltmeter lead in each motor wire
Gently spin the motor flywheel and check for voltage DC
0 VDC means motor malfunction
DRIVE BELT TENSION TEST
This test is used in front roller replacement and in conditions of belt slipping.
Place two fingers on top of the drive belt halfway between the front roller pulley and the drive motor pulley.
With moderate pressure push down on belt
If belt deflects down more than 1/8 “, tighten motor mounts If belt deflects down less than 1/8 “, loosen motor mounts.
It is also possible to twist the belt; you should be able to twist the belt almost to a vertical position
TREADBELT TENSION TEST
This test will address belt slipping and is used in any roller replacement or deck replacement. Ensure that the drive belt is properly tensioned before adjusting tread belt tension. Belt and deck wear and/or lack of lubrication can cause the tread belt to show symptoms similar to loose tread belt tension- check these conditions before adjusting tread belt tension.
Turn treadmill on and adjust speed to 2 mph
Walk heavily on the belt pulling slightly against belt movement
If hesitation or slip is detected, tighten tread belt tension bolts ¼ turn
Repeat until no hesitation or slip is encountered. Check at higher speeds
Tread belt tension is too tight if the belt feels stiff to touch with no give or the belt groans against the rollers. You should be able to insert your hand between the belt and deck palm up almost to your thumb when the belt is at proper tension.
