KEEP ENGINE STANDING STILL DURING INSPECTION AND MAINTENANCE
• Before starting inspection and maintenance servicing, be sure to
retract the crane and stop the engine.
• Turn the starter switch to the “OFF” position and set the lock lever
(1) to the “Lock” position (L).
• Operate the left and right travelling levers full strokes forward and
backward 2 to 3 times to relieve the pressure remaining in the
hydraulic circuits.
After turning the starter switch OFF, wait for approximately 1
minute and push the horn switch to check that the horn does
not sound.
• Apply pawls to prevent crawler from moving.
WORK BY AT LEAST TWO PERSONS DURING MAINTENANCE WITH ENGINE RUNNING
To prevent accidents, do not attempt maintenance when the engine
is running.
Always observe the following in case of maintaining with the engine
running for unavoidable reason.
• One person should sit at the operator’s seat. Keep checking each
other while ensuring that the engine can be stopped at any time.
• When working near such rotating parts as fan, belt, and winch
drum, keep the operator’s body and any object that can be readily
caught away from these parts.
• Never allow any object or tool to fall on or insert into the rotating
parts of fan, belt and winch drum. Such an object may hit the
rotating part or spring back from it, and thus it is dangerous.
• Do not touch operation levers. If it is unavoidable to use the
operation levers, always give a sign to the other person and let
him/her evacuate to a safe place.
• Relieve the pressure remaining in the hydraulic circuits and set
the lock lever (1) to the “Lock” position (L).
Refer to “Inspection and Maintenance 2. Basic Maintenance
(Hydraulic Equipment Handling)” for details.
• Do not touch operation levers and pedals. If it is unavoidable to
use the operation levers and pedals, always give a sign to the
other person and let him/her evacuate to a safe place.
