10.3 OPERATION OF DISABLED MACHINE
10.3.1 LOWERING ATTACHMENT OF DISABLED MACHINE
•The following procedure should be used only in case of machine failure. Always use extreme caution
during operations. Keep other persons away from the bucket, attachment and boom.
•The bucket or attachment can move unexpectedly during operations due to weight of the bucket,
attachment, arm or boom.
•Keep away from the space under the bucket or attachment when lowering the bucket or attachment.
In cases where the machine fails and the engine stops, lower the attachment by using the procedure
described below.
The steps 1 to 6 should be completed in five minutes after the engine stops because the accumulator
pressure gradually falls to disable the operation of lowering the attachment.
1. Move the pilot control shut-off lever to the
"LOCKED" position.
2. Turn the starter switch to the "OFF" position.
3. Make sure all control levers are set to their
"NEUTRAL" positions.
4. Turn the starter switch to the "ON" position.
5. Move the pilot control shut-off lever to the
"UNLOCKED" position.
6. Use the left and right control levers to lower
the attachment slowly until it touches the
ground.
