General Fault Isolation
Visual Inspection
A thorough visual inspection of the equipment can save time. Small
things—disconnected cables, foreign debris on circuit boards, missing
hardware, loose component—can frequently cause symptoms and
equipment failures that may appear to be unrelated and difficult to
track.
Take the time to make all of the recommended visual checks (refer to
the visual inspection chart on the next page) before starting any detailed
troubleshooting procedures.
Power Down
Set the treadmill’s power switch to off (0). Disconnect the power cord
from the AC wall outlet.
NOTE
Before performing any maintenance or repair
on the equipment, take precautions against
electrostatic discharge damage. See
“Controlling Electrostatic Discharge” in
chapter 3.
NOTE
Solder multilayer and surface mount PCB
assemblies at your own risk! Improper repair
methods can damage the PCB assemblies
even further. Only qualified service
personnel with the proper equipment should
attempt to repair PCBs.
WARNING
Unplug unit before
performing the
following procedure.
