Secondary Boom Lift Cylinder

The secondary boom lift cylinder raises and lowers

the secondary boom. The secondary boom lift

cylinder is equipped with counterbalance valves to

prevent movement in the event of a hydraulic line

failure.

How to Remove the Secondary

Boom Lift Cylinder

Bodily injury hazard. This

procedure requires specific repair

skills, lifting equipment and a

suitable workshop. Attempting

this procedure without these skills

and tools could result in death or

serious injury and significant

component damage. Dealer

service is strongly recommended.

Note: When removing a hose assembly or fitting,

the O-ring (if equipped) on the fitting and/or hose

end must be replaced. All connections must be

torqued to specification during installation. Refer to

Specifications,

Hydraulic Hose and Fitting Torque

Specifications.

1 Rotate the turntable to either side until the

boom is centered between the steer and

non-steer tires.

2 Raise the primary boom to full height. Do not

extend it.

3 Swing out the battery pack that is directly

below the secondary boom lift cylinder.

4 Disconnect the battery packs from the

machine.

5 Open the hydraulic tank side turntable cover.
6 Tag and disconnect the power cables on the

auxiliary power unit.

Electrocution/burn hazard.

Contact with electrically charged

circuits could result in death or

serious injury. Remove all rings,

watches and other jewelry.

7 Close the hydraulic tank shutoff valve. Tag

and disconnect and plug the hydraulic hose

from the hydraulic tank shutoff valve.

Bodily injury hazard. Spraying

hydraulic oil can penetrate and

burn skin. Loosen hydraulic

connections very slowly to allow

the oil pressure to dissipate

gradually. Do not allow oil to

squirt or spray.

8 Open the valve on the hydraulic tank and drain

the oil into a container of suitable capacity.

Refer to Specifications.,

Machine

Specifications.

Bodily injury hazard. Beware of

hot oil. Contact with hot oil may

cause severe burns.
