HYDRAULIC HOSE IDENTIFICATION
Where necessary, the hydraulic hoses and corresponding
couplers have identification tags (5) as shown in Figure 4-7
.
Match the number on the hose with the number on the decal
or the corresponding coupler to ensure proper connection.
CONNECTING/DISCONNECTING
HYDRAULIC HOSES AND ELECTRIC
CABLES
Always STOP ENGINE before performing the following steps
during crane assembly and disassembly:
• Connecting and disconnecting hydraulic lines. It will be
easier to connect and disconnect the couplers when
there is no pressure in the system.
• Connecting and disconnecting electric cables. The
potential for damage to the electric components exists if
the engine is not stopped.
NOTE: To stop the engine if it was started from the remote
control, turn the external engine switch COUNTER-
CLOCKWISE to the STOP position.
To stop the engine if it was started from the cab,
use the ignition switch in the cab.
HOSE AND CABLE CLEANLINESS
To prevent dirt from entering the hydraulic systems or from
damaging the electrical connectors:
• Thoroughly clean hydraulic fittings and electric
connectors before connecting them.
• Thoroughly clean protective caps before attaching them
to hoses, tubes, or cables.
• Do not drag hydraulic hose fittings or hoses and
electrical connectors or cables on the ground.
NOTE: Apply a light coat of silicone lubricant to the threads
of all protective caps, couplers, and connectors to
help in preventing the threads from seizing.
