Use a platform, and secure your body with three
locations of the limbs (both feet and one hand,
or both hands and one foot) when climbing up or
down the machine.

Cautions When Replenishing Fuel or Oil
Fig. 5-11
Fig. 5-12
The fuel, oils and similar substance may catch fire
if a fire comes near.
Light petroleum is used as the fuel and thus
requires extra effort to observe the followings.
• Keep the engine stopped when supplying.
• Do not smoke when supplying.
• Immediately wipe away dripped fuel or oil.
• Securely tighten the fuel and oil caps.
• Supply fuel/oil at a location with good ventilation.
• Do not leave the site when replenishing the fuel
or oil.
Beware of Chips When Working with
Hammer
Fig. 5-13
During the hammering works, keep protective
equipment such as protective glasses and a
helmet on, and insert a copper bar or similar
object between the hammer and the target when
hitting.
Giving impact to a hard metal part such as a pin or
a bearing may cause the broken chip to enter eye
and inflict injury.
Cautions During Welding Repair
Weld in a location with good facility, and, only
authorised personnel are permitted to weld.
Unauthorised personnel are strictly prohibited
since risks such as gas generation, fire and
electrical shock are present when welding.
The personnel authorised to weld are requested
to always observe the followings.
• Disconnect the battery terminals to prevent
battery explosions.
• Peel off the paint from the welding section to
prevent gas generation.
• Attempt to heat up a hydraulic machinery, piping
or a section near such part may cause
combustible vapour or mist to be generated and
catch fire. Avoid heating such section.
• Directly heating a pressurised piping or rubber
hose may cause a sudden snip. Apply a fire
protection cover.
• Disconnect the wiring connectors of the radio
control and remote control system, moment
limiter display and converter.
• Put on protective equipment.
• Keep the ventilation well.
• Put away the combustibles and prepare a fire
extinguisher.
• Do not ground to a location near electrical part.
Such may cause the electrical part to
malfunction.
