Repair/Replacement and Calibration
The procedures that follow apply to the following treadmills: ST55,
ST65, TM55, and TM65. Field repair and replacement is to the modular
level. No procedures are included for component-level repair.
Electrical Shock
Warning!
High voltage is present beneath the treadmill hood while
the treadmill is connected to a power source. Residual high
voltages remain for a few minutes after the plug is
removed.
To prevent high-voltage electrical shock:
— Turn off the treadmill circuit breaker, then unplug the
treadmill and stress monitor power cords every time you
remove the hood.
— Before working on or around any electrical or
mechanical component under the hood, wait at least two
minutes from the time you unplug the power cord and be
sure the red LEDs on the drive board on the AC Drive
Module are off.
The power control on the stress monitor does not turn off
electrical current to the treadmill.
Be sure treadmill area is free of liquid spills before
removing hood.
Burns
Warning!
Allow pulleys, chain, motor, and other treadmill parts to
cool sufficiently before touching them.
Unplug the treadmill immediately if signs of overheating
occur.
