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 ON position and move each of the
left and right operating levers back and forth to the full
stroke for 2 to 3 times so that the residual pressure in the
hydraulic circuit is relieved. Set the lock lever (1) to LOCK
position (L) to turn the starter switch OFF.
• Check to ensure that the battery relay is turned OFF and
main power current is not turned ON.
After turning the starter switch OFF, wait for
approximately 1 minute and push the horn switch. If the
horn is not honked, no current is ON.
• Turn the disconnect switch in the battery box OFF to shut
off the power supply circuit in order to prevent the system
from unexpectedly activated during inspection and
maintenance servicing.
• 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 occupy the operating seat to be ready
for stopping at any time, and keep communications each
other.
•
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.
• Set the lock lever (1) to the "LOCK" (L) position.
Refer to the descriptions under "MAINTE
NANCE 12.
RELIEVING INTERNAL PRESSURE OF HYDRAULIC
CIRCUIT."
• 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.
