INTERMEDIATE BOOM MAINTENANCE - CONTINUED

REMOVAL

WARNING

Do NOT remove hydraulic tank filler cap or disconnect or remove any hydraulic system line or fitting unless

hydraulic system pressure has been relieved. Hydraulic system pressure can be over 3,000 psi (20685 kPa),

even with engine and pump OFF. To relieve pressure, lower all hydraulic attachments to the ground and shut

down engine. Move control levers through all operating positions, then SLOWLY loosen hydraulic tank

filler cap. After maintenance, tighten all connections before applying pressure. Escaping hydraulic fluid

under pressure can penetrate the skin, causing injury or death.

CAUTION

Wipe the area clean around all hydraulic connections to be opened during removal and disassembly. Cap oil

lines and plug holes after removing lines. Contamination of the hydraulic system could result in premature

failure.

NOTE

If more than one hydraulic line is to be

removed, identify lines to assure proper

installation. Use container to catch any

hydraulic oil that may drain from system.

Be sure rope used during inner boom removal

(WP 0263 00) is placed in intermediate boom

and fastened at each end.

Attach a hoist with slings (or other lifting device) to

intermediate boom (1). Use hoist to remove intermedi-

ate boom (1) 3/4 way out from outer boom (2).

NOTE

Note location and quantity of wear pad com-

ponents. Tag all components as removed.

Raise or lower sling as required during steps

2 and 3 to provide work room when remov-

ing wear pad assemblies.

Remove capscrews (5), lockwashers (6) and flatwash-

ers (7). Discard lockwashers.

Remove wear pads (3) and wear pad inserts (4) from

front of outer boom (2).
