Page: 25 / 100

Clean the Machine before Inspection
or Maintenance
Dirt and debris on the machine not only prevents
easy detection of faulty components or parts but
also can be trapped in components or parts. Also,
dust or mud can enter your eyes or cause you to
slip and be injured.
Before starting general inspection or maintenance
activities, wash the machine to ensure a safe work
area.
Cautions for Washing the Machine
Wet footing can cause to slip and fall injuries.
Always wear non-slip shoes.
When washing the machine with high-pressure
steam, the jet can penetrate skin or flying mud can
cause eye damage. Always wear suitable protective
gear during washing.
Do not direct water to electrical equipment, dis-
charge and/or shortcircuits can result and lead to
damage.
Inspect and Maintain the Machine on
Level Ground
It is difficult to inspect the machine properly if it is
parked on a slope or grade. Also, the machine is li-
able to start moving if not parked properly.
Park the crane on firm flat ground, activate the park-
ing brake, and chock the tires.
Keep the Work Area Clean and Tidy
Performing inspection or maintenance work in a dis-
orderly place can lead to personal injury or a falling
accident.
Remove obstacles.
Labeling for Inspection or
Maintenance Work
If any unauthorized person starts the engine during
inspection or maintenance work, the machine may
be damaged or injury or even death may result.
When performing inspection or maintenance work,
remove the starter key, and post a “DO NOT OPER-
ATE” or “TAG OUT” sign on the door or control
levers of the operator’s cab as a warning.
Also, post relevant warning signs at entry to the
work area to prevent access of unauthorized per-
sonnel.
Start Inspection or Maintenance after
the Machine Has Cooled Down
When the crane is operated, various machine com-
ponents become very hot and can cause burns.
These components include the engine, muffler, en-
gine cooling water, radiator, hydraulic oil, reducer,
hydraulic equipment and hydraulic piping.
Allow these components and areas to cool down be-
fore starting inspection or maintenance work.
Beware of High-Pressure Oils
High-pressure fuel or hydraulic oil that comes into
contact with skin or eyes can cause serious injury.
To avoid this danger:
• Release internal pressure, and only then, discon-
nect any piping.
• To check for leakage, wear protective goggles and
gloves and use a piece of cardboard or wood as a
monitor. Leaking high-pressure oil may be invisi-
ble.
Keep bare hands away from all leaking compo-
nents.
• Immediately obtain medical attention when high-
pressure oil accidentally cuts into skin or affects
the eyes.
