The procedures that follow apply to both the ST 55 and the ST 65
treadmills. Field repair and replacement is to the modular level.
No procedures are included for component-level repair.
WARNING
ELECTRICAL SHOCK
High voltage is present beneath the treadmill hood while the
treadmill is connected to a power source. Residual high volt-
ages 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 ECG 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 VSD board are off.
The power control on the ECG monitor does not turn off
electrical current to the treadmill.
Be sure treadmill area is free of liquid spills before removing
hood.
BURNS
Allow pulleys, chain, motor, and other treadmill parts to cool
sufficiently before touching them.
Unplug the treadmill immediately if signs of overheating
occur.
MECHANICAL HAZARDS
Be sure the treadmill power cord is unplugged before work-
ing with chains, rack gear, belt, and pulleys.
Secure long hair, loose clothing, and jewelry before working
near the treadmill, particularly near walking surface and
rotating parts.
Before running the treadmill, check for worn parts which
could break loose during service or operation.
Keep fingers away from rotating parts.
To avoid eye contaminants, clean away dust and debris from
moving parts before servicing.
Beware of sharp edges when replacing worn parts.
Do not start the walk belt when someone is on the treadmill.
