6.4 ELECTRIC MOTOR MAINTENANCE
Periodically check the condition of the following electric
motor components.
Electric Motor
The electric motor is located inside of the rear hydraulic valve
distributor support cover.
• POWER SUPPLY TERMINALS
Check tightness of the nuts on the power supply termi-
nals and make sure the insulation is intact.
• FAN
Keep air intakes clean and make sure the fan can rotate
freely.
• BEARINGS
Check the condition of the bearings, in the event of noise
contact JLG for replacement, the life of the bearings is
reduced significantly in heavy duty operating conditions.

be checked or replaced.
