How to Remove the Generator
DANGER
High voltage. Exposure to
electrical wires or electrical
current will result in death or
serious injury. Remove all rings,
watches and other jewelry. Turn
off all power when not needed
for testing. Use extreme caution
when working with high voltage
electrical components.
DANGER
Electrocution/burn hazard.
Attempting to service the machine
before the capacitor is fully
discharged will result in death or
serious injury.
Note: Be sure the engine has been turned off for
at least 15 minutes before servicing the machine.
Use a voltmeter to confi rm there is no residual
voltage in the capacitor.
1 Deploy the outriggers and level the machine.
2 Fully raise the mast.
3 Select and open a cabinet door. Tag and
disconnect the gas strut, then continue to open
the door until it comes to rest above the top
panel of the cabinet. Repeat for the other side
of the machine.
4 With both cabinet doors fully opened and above
the top panel of the cabinet, secure the doors
together using a length of rope or elastic cord.
5 Attach a lifting strap from an overhead crane to
the top panel and doors assembly. Support the
assembly. Do not apply any lifting pressure.
Notice: Component damage hazard. The cabinet
doors and/or hinges can become damaged if
excessive pressure is placed on the components.
Use a spreader bar to ensure the lifting strap does
not make contact with any portion of the doors.
6 Remove the fasteners securing the top cabinet
panel to the front and rear cabinet end panels.
Remove the top cabinet panel and doors
from the machine and place it on a support of
adequate capacity.
7 Pull the cover off the top of the capacitor box to
access the wire harness where it connects to
the generator.
CAUTION
Burn hazard. Contact with hot
engine components may cause
severe burns. Use caution when
working around a hot engine.
8 Using an insulated conductor or a screwdriver
with an insulated handle, discharge the
capacitor by shorting across the capacitor
terminals. Repeat for the second capacitor, if
equipped.
DANGER
High voltage. Exposure to
electrical wires or electrical
current will result in death or
serious injury. Remove all rings,
watches and other jewelry. Use
extreme caution when working
with high voltage electrical
components.
