7.2 PRECAUTIONS DURING MAINTENANCE
NO ENTRY OF UNAUTHORIZED PERSONNEL
Do not allow anyone, other than the necessary personnel, to enter the site during
maintenance. Post a guard, if necessary.
Take special care in case of polishing, welding work, or digging work.
MEASURES UPON FINDING ABNORMALITY DURING INSPECTION
• Always repair whenever any abnormality is found during inspection.
Attempt to use without repairing the defect may cause 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. Dropping object may damage the Machine or
cause the Machine to operate improperly and thus may cause accidents.
If anything drops, always retrieve it.
• Do not keep anything unnecessary for the inspection in your pocket.
NOISE CAUTION
Large noise in the surroundings may cause hearing difficulty or deafness.
Use ear protection or ear plugs during long-term noise exposure, such as 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 following in case of maintaining with the
engine running for unavoidable reason.
• One person should sit at the driver’s seat. Keep checking
each other while ensuring that the engine can be stopped at
any time.
• Be especially careful when working near a rotating part
because you may be entangled.
• 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.
• Do not touch the alternator belt or other parts, as this may
break tools or severe limbs.
CAUTIONS WHEN WORKING UNDER MACHINE
• Park the Machine on a level and firm place, and fully retract
and lower the boom.
• Before the maintenance under the Machine, extend the
outriggers to maximum so the Machine lifts. At this moment,
insert support platforms (jack stands) below the front and
rear parts of the machine frame to stabilize the machine.
