low idle and check the machine for any visual sign of
fluid leakage. STOP the engine immediately if any
leakage is noted, and make any necessary repairs
before continuing.

level. Add coolant as required to bring the coolant to
the proper level.
4.4 CAB REMOVAL
Inspect the cab, its welds and mounts. If modification,
damage, a cracked weld and/or fatigued metal is
discovered, replace the cab. Contact the JLG distributor or
the JLG Service Department with any questions about
the suitability or condition of a cab.
Note: Remove and label cab components as needed
before removing the cab from the machine. Label,
disconnect and cap hydraulic hoses. Transfer cab parts
to the replacement cab after the replacement cab is
securely mounted on the machine.
1. Park the machine on a firm, level surface. Allow
sufficient overhead and side clearance for cab
removal. Level the machine, ground the attachment,
place the travel select lever in the (N) NEUTRAL
position, engage the parking brake and shut the
engine OFF.
2. Open the engine cover. Allow the system fluids to
cool.
3. Disconnect the battery negative (-) cable at the
battery negative (-) terminal.
4. Shut both coolant valves located on the engine.

6. Remove the air cleaner tubing from the side of the
cab. Cover the intake opening on the engine to
prevent dirt or debris from entering the engine.
7. Disconnect the wiring harness between the cab and
frame.
Note: Record the location, and label all hoses to ensure
correct installation.
8. Working under the cab, label, disconnect all
hydraulic hoses. Cap all fittings and openings to
keep dirt & debris from entering the hydraulic
system.
