5.2 PRECAUTIONS DURING MAINTENANCE
NO UNAUTHORIZED PEOPLE
Do not admit anyone other than necessary workers during maintenance. And post a guard as
necessary.
Be especially careful in case of a polishing, welding work, or digging work.
MEASURES UPON FINDING ABNORMALITY DURING INSPECTION
• Always repair whenever an abnormality is found during inspection.
Attempt to use without repairing the defect may cause bodily accidents.
• Ask us or our sales service agency for repair depending on the failure type.
DO NOT DROP TOOLS OR PARTS INSIDE THE MACHINE
• Do not drop any bolt, nut or tool inside the Machine when inspecting while opening the inspection port
or tank replenishment port. Dropped objects may damage the Machine or cause the Machine to
operate improperly and thus may cause accidents. If dropped, always retrieve.
• Do not keep anything unnecessary for the inspection in your pocket.
NOISE CAUTION
Large noise in the surroundings may cause hearing difficulty or deafness.
Put on ear covers or earplugs before long time noise exposure for instance an engine maintenance.
WORK TO BE CARRIED OUT BY AT LEAST TWO PEOPLE DURING MAINTENANCE WITH
THE ENGINE RUNNING
To prevent accidents, do not attempt maintenance when the engine
is running.
Always observe the followings in case of maintaining with the engine
running for unavoidable reason.
•
One should be in an operable position by the travelling operation
unit of the machine and be ready to stop the engine whenever
necessary, and both should keep a good interaction, as well.
• Be especially careful when working near a rotating part which may
become entangled.
• Do not touch operation levers. Before handling an operation lever
for unavoidable need, always give a sign to other person and let
him/her evacuate to a safe place.
PRECAUTIONS WHEN WORKING BELOW THE MACHINE
•
Park the Machine over a level and firm location, and fully retract and
lower the boom.
• Before the maintenance below the Machine, extend the outriggers
to the maximum so the Machine lifts. When doing so, insert support
platforms (height increasers) below front and rear of the Machine to
stabilize the Machine.
