4.5 CAB REMOVAL
IMPORTANT: To help ensure safety and optimum
performance, replace the cab if it is damaged. Refer to
the appropriate parts manual for ordering information.
Before performing any inspection, maintenance or
service operation, thoroughly clean the vehicle. DO NOT
spray water or cleaning solution in, on, near or around the
operator’s dash panels and electrical components.
Inspect the cab, its welds and mounts. If modification,
damage, a cracked weld and/or fatigued metal is
discovered, replace the cab. Contact your local Lull
distributor or the JLG Service Department, with any
questions about the suitability or condition of a cab.
IMPORTANT: Remove and label cab components as
needed before removing the cab from the vehicle. Label,
disconnect and cap hydraulic hoses. Transfer cab parts
to the replacement cab after the replacement cab is
securely mounted on the vehicle.
1. Park the vehicle on a firm, level surface. Level the
vehicle, ground the attachment, place the travel
select lever in the (N) NEUTRAL DETENT position,
engage the parking brake switch and shut the
engine OFF.
2. Unlock and open the engine cover. Allow the engine
and hydraulic fluid to cool.
3. If the vehicle has dual batteries, disconnect both
negative battery cables (1 and 2) from both
batteries.
To access the lower battery (3), loosen the knob (4)
far enough so that the lip (5) on the upper battery box
clears the knob. Lift up the upper battery box (6) and
swing it out, so that the box clears the hydraulic tank
support bracket, to gain access to the lower negative
battery cable (1). Disconnect the lower negative
battery cable.
WARNING:
Risk of death or serious
personal injury. NEVER modify, weld or drill
the cab.
