3.3.1 Inner Boom Removal
1. Remove any attachment from the quick attach
assembly. (Refer to Section 3.10.1, “Disconnecting
from an Attachment.”)
Note: If you are replacing the inner boom with a new
inner boom, remove the quick attach from the inner
boom. (Refer to Section 3.10.3, “Quick Attach Removal.”)
Note: This procedure will require a clear space of
approximately 16 feet at the front of the vehicle.
1. Park the vehicle on a hard, level surface. Move the
boom to a horizontal (level) position. Extend (or
Retract) the boom until the boom is extended
approximately 2 feet (610 mm). Move the quick
attach to the horizontal position. Place the travel
select lever in the (N) NEUTRAL position, place the
neutral lock lever in the (N) NEUTRAL LOCK
position, engage the parking brake and shut the
engine OFF.
2. Return to the cab, fasten your seat belt and start the
engine. Retract the boom slightly until slack is
noticed in the extend chain. Shut the engine OFF.
3. Place an Accident Prevention Tag on both the
ignition key switch and the steering wheel, stating
that the vehicle should not be operated. (Refer to
Section 1.5, “Accident Prevention Tags.”)
4. Unlock and open the engine compartment cover.
Allow the engine, transmission and hydraulic fluid to
cool before proceeding.
5. Disconnect the battery negative (-) cable at the
battery negative (-) terminal to prevent the engine
from starting accidentally.
6. Move the Attachment Tilt joystick in both directions
to relieve any trapped pressure in the Attachment Tilt
system. If your vehicle is equipped with optional
auxiliary hydraulics, move the auxiliary hydraulic
joystick in both directions to relieve any trapped
pressure in the auxiliary hydraulic system.
7. Locate the two hoses (1) attached to the base of the
Attachment Tilt cylinder (2) inside the gooseneck (3).
8. Label and remove the hoses (1) from the fittings (4)
on the Attachment Tilt cylinder. Plug the hose ends
and cap the fittings on the Attachment Tilt cylinder to
prevent dirt and debris from entering the hydraulic
system and/or cylinder.
WARNING:
Wear protective footwear
with reinforced toe caps and slip-resistant
soles. Failure to comply can result in foot or
other bodily injury from crushing, slipping or
falling.
WARNING:
NEVER lift a heavy object
without the help of at least one assistant or a
suitable sling and hoist. Failure to comply can
result in death or serious personal injury.
WARNING:
Hydraulic fluid leaking under
pressure can penetrate the skin, cause infection,
gangrene, and death or serious personal
injury. If injured, see a doctor immediately.
Relieve all pressure before disconnecting any
component, part, line or hose. Slowly loosen
parts and allow release of residual pressure
before removing any parts or component.
WARNING:
Wait for the hydraulic fluid
to cool before servicing any hydraulic component.
Hot hydraulic oil can cause severe burns.
