Checklist B Procedures
B-1
Inspect the Electrical Wiring
Genie requires that this procedure be performed
every 250 hours or quarterly, whichever comes
first.
Maintaining electrical wiring in good condition is
essential to safe operation and good machine
performance. Failure to find and replace burnt,
chafed, corroded or pinched wires could result
in unsafe operating conditions and may cause
component damage.
WARNING
Electrocution/burn hazard.
Contact with hot or live circuits
could result in death or serious
injury. Remove all rings, watches
and other jewelry.
1 Inspect the following areas for burnt, chafed,
corroded and loose wires:
• Inside of the operator's compartment
• Underside of the chassis
• Boom assembly
2 Inspect for a liberal coating of dielectric grease
in the following locations:
• All harness connectors
3 Start the engine and raise the boom so there
is enough room to access and remove all the
covers attached to the chassis.
4 Attach a lifting strap from an overhead crane to
the boom. Support the boom. Do not apply any
lifting pressure.
5 Remove all engine covers and chassis covers.
DANGER
Crushing hazard. Death or
serious injury could result if the
boom should unexpectedly fall
while working underneath the
boom. Do not stand or work
beneath a boom that is not
properly supported.
6 Inspect the following areas for burnt, chafed,
corroded, pinched and loose wires:
• Engine
• Transmission
• Manifolds
• Chassis
7 Inspect for a liberal coating of dielectric
grease in all connections between the engine,
transmission and the operator's compartment.
8 Install all covers removed in step 5.

crane.
