2. TROUBLE SHOOTING
Perform lockout/tagout procedures before adjusting, lubricating,
cleaning or otherwise servicing. Failure to do so could result in unexpected startup and
could cause serious injury or death.
Troubleshooting the maintenance lift is relatively simple for maintenance personnel
who have a working knowledge of automotive repair and electrical and hydraulic
systems. The work requires no tools other than those found in any well-equipped
automotive maintenance shop.
The following notes may help with your understanding of how the maintenance lift is
designed to operate:
• The engine starter will not engage unless the transmission shift lever is in
neutral position, the ignition switch is in “Run” position, and no emergency stop
switches are depressed
• The ignition switch on the instrument panel is of the anti-restart type, which
means once the engine has been cranked, the switch must be turned back to
OFF before the engine can be cranked again.
• The “High Water Temp.” and “Brake Fault” lights are self-testing and designed
to flash briefly whenever the ignition switch is turned on or off. This tests the
lamp and socket to ensure proper functioning.
• Due to tire static resistance on dry pavement the wheels may not be able to
turn fully from lock to lock when unit is stationary.
• The Platform Up/Down function will not operate unless the transmission shift
lever is in neutral, the parking brake is set and the stabilizers are fully extended.
• Platform and Stabilizer functions will not operate unless “Operational (Platform)
Safety” switch is operated simultaneously.
• Stabilizers cannot be retracted unless the platform is fully lowered.
• The vehicle cannot be moved with stabilizers down. Engine will die if the
transmission lever is shifted from neutral position. “Retract Stabilizers” light will
illuminate.
• A starter protection relay prevents the starter from being cranked by either
ignition switch once the engine is running.
• The engine will operate only if both ignition switches (chassis and platform)
are in “Run” position. If the platform ignition switch is in “Off” position and the
chassis switch is in “Run” position, “Remote Switch Off” light will illuminate and
the starter will not engage.
