Rubbing, Scraping, Squeaking Or Popping Noises - Bodyguard T-30 User Manual

TREADMILLS – USER MANUAL
try to bend the wing back straight by applying heat to the plastic wing with a hairdryer. The heat will
allow the wing angle to be manipulated easier and then stay in the preferred position when it cools.
Alternatively, an edge of a wing can be clipped if necessary.

RUBBING, SCRAPING, SQUEAKING OR POPPING NOISES

A noise that sounds as if it is rubbing, scraping or squeaking is almost certainly related to something
making permanent contact with a moving part. You should be able to replicate the noise when no one
is on the treadmill and possibly increase its volume by increasing the speed making it easier to
diagnose.
Permanently moving parts on an operating treadmill include the walking and drive belts, front and
rear rollers and the drive motor and its connecting parts such as the flywheel, fan and optic disc. If
something is in permanent contact with one of these parts then the rubbing or scraping noise is likely
to get louder as the speed increases.
Walking Belt Alignment
Check that the walking belt is centered and the not making contact with the foot rail or front roller
pulley. (see Walking Belt Alignment in section 7.5)
Walking Belt & Foreign Object / Debris
Check that nothing is located under the treadmill and rubbing on the walking belt.
Check that the underside of the walking belt is not making contact with the top edge of the deck at
the front or back. If so, there should be traces of dust where the underside of the walking belt is
"sanding" down the front or back edge of the deck. Tighten the deck down to lower it away from the
walking belt or sand off the deck edge so no contact with the walking belt can be made.
Check that there is no debris stuck between the walking belt and deck or foot rails.
Drive Motor Brushes
A chipped or worn drive motor brush can make a chirping or squeaking noise when it makes contact
with the commutator. Turn off the power and unplug the power cord, remove the motor cover and
remove the drive motor brush cap and gently push the motor brush in and turn the motor flywheel.
DO so several times and try to smooth out the motor brush. If this does not solve the problem,
carefully release the spring holding the squeaking drive motor brush in place and pull out the brush.
Lightly sand the drive motor brush with fine sand paper until the brush is smooth and no rough spots
can be seen. Reinsert the brushes into the drive motor and reengage the spring and test.
Drive Belt
If the drive motor pulley and front roller pulley are misaligned the grooves in the drive belt may
become worn as they rotate around the misaligned grooves in the pulleys and make a scraping,
squeaking or popping noise. Clean the belt with mild soapy water (no belt dressing) and realign the
pulleys. If the belt is too damaged it will need to be replaced.
Drive Motor Pulley
Check that the grooves in the Drive Motor Pulley are clean as debris stuck in these grooves can
cause the drive belt to make squeaking or scraping noise during operation. Loosen and remove the
drive belt and clean the drive motor pulley grooves with a wire brush.
Front or Rear Rollers
Check that nothing irregular is making contact with the front or rear rollers, including the front left
roller pulley. Confirm the roller axels are secured tightly to the fame and rollers have no vertical
movement.
