Boom
6. Loosen the extend chain locknut (10), located at the
rear of the outer boom (11), half way. The locknut
must remain fully engaged on the threads of the
extend chain clevis.
7. 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.
8. Move the attachment tilt joystick in both directions to
relieve any trapped pressure in the attachment tilt
system. Move the auxiliary hydraulic joystick in both
directions to relieve any trapped pressure in the
auxiliary hydraulic system.
9. Place an Accident Prevention Tag on both the
ignition key switch and steering wheel, stating that
the vehicle should not be operated. (Refer to Section
1.5, “Accident Prevention Tag Usage.”)
10. Unlock and open the engine compartment cover.
Allow the engine, transmission and hydraulic fluid to
cool before proceeding.
11. If the vehicle has dual batteries, disconnect both
negative battery cables (12 and 13) from both
batteries.
To access the lower battery (14), loosen the knob
(15) far enough so that the lip (16) on the upper
battery box clears the knob. Lift up the upper battery
box (17) and swing it out, so that the box clears the
hydraulic tank support bracket, to gain access to the
lower negative battery cable (12). Disconnect the
lower negative battery cable.
12. Remove two retaining rings (18) and clevis pin (19)
to disconnect the extend chain yoke (20) from the
outer boom. Lay the chain assembly flat against the
inner boom (21).
