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 TOOL OR PART INSIDE MACHINE
• Do not drop any bolt, nut or tool inside the Machine when inspecting while opening the inspection port
or tank replenishment port. Dropped object 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 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 followings in case of maintaining with the engine
running for unavoidable reason.
• One should seat in the driving seat, and keep checking each other
while ensuring that the engine can be stopped any time.
• Be especially careful when working near a rotating part which may
entangle.
• 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.
• Do not contact with the alternator drive belt or other part that severs
upon contact with human body or tool.
CAUTIONS WHEN WORKING BELOW MACHINE
• Park the car over a level and firm location, and fully retract and
lower the boom.
• Before the maintenance below the Machine, extend the outriggers
maximum so the Machine lifts. When doing so, insert support
platforms (height increasers) below front and rear of the Machine to
stabilize the Machine.
