scraping noise in all modes

walking on unit
"Tick" sound once per
revolution or scraping noise
from under treadle
Troubleshooting
Things to Check
Belt alignment
Rollers or motor
Belt tension
Walking belt tension
Drive belt
Belt alignment
Solution
Check walking belt alignment. Belt contact with metal
guides under treadle can make loud grinding sound. If
belts are misaligned, follow Belt Alignment procedure
in this manual.
Contact customer service for further assistance.
If belt hesitates or slips when walking on unit, it may be
caused by either a loose walking belt or a loose drive
belt. To determine the cause, do the following test:
1. Stand beside TreadClimber
speed to 2 MPH.
2. Step on one treadle and attempt to stop movement.
If one belt stops but roller at rear and other belt
continue to turn, adjust walking belt tension.
If both belts stop but motor is still turning, the drive belt
tension should be adjusted.
Adjust walking belt tension at the front of the unit
using the 3/16 hex key on the adjustment bolts on
each side of each front roller. Tighten (turn clockwise)
each adjustment bolt in full turn increments. Be sure
to adjust both bolts on each roller the same amount
to keep belt alignment. 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.
Disconnect power cord from machine
!
and wait 5 minutes to ensure no residual
power remains.
Turn unit on its side to expose its underside. Verify
motor is installed securely with shipping bolt removed:
- Motor bracket mounting tabs visible on underside of
machine
- Motor keeper in place
- Shipping bolt removed
Return machine to upright posiition. Remove left rear
plastic cover to expose "v" belt drive line and motor.
Check belt installation. The grooved side of the belt
should be in contact with the drive and motor pulleys;
the smooth side should be facing out.
Check motor tensioning assembly:
- Verify plastic bushings are not broken. If broken,
replace motor tension bolt kit.
- Verify bushings and spring are oriented correctly.
If belt is still loose, use a 1/2" wrench or socket to
tighten motor tension nut. Check belt tension after each
full turn. Belt should feel taut, but should still allow 1/8"
- 1/2" deflection when pressed at the mid point. DO
NOT OVER TIGHTEN.
Replace cover when finished.
Belt seam may be contacting metal belt guide under
treadle. Slight adjustment of belt should alleviate
noise. Follow Belt Alignment procedure in this manual.
