ATTACH A WARNING TAG
When draining coolant and oil, always pull off the starter switch key to prevent accidental engine
ignition. Also, attach a warning tag to the work machine operating lever.
FOLLOW SAFETY PRECAUTIONS
Safety precautions provided on the machine should always be followed when using the machine.
PRECAUTIONS DURING WELDING REPAIR
• Make sure the machine is turned off. (Turn the starter switch to the “OFF” position.)
• Do not continuously apply 200 V or greater.
• Ground the machine within 1 meter from the welding point.
• Pull out the connectors for the moment limiter display and moment limiter converter.
• Remove the negative (
−
) terminal of the battery.
• Make sure no sealing or bearing is present between the welding point and the grounding point.
Potential damage to sealing may occur due to sparks if disregarded.
• Do not ground around the boom pin or the hydraulic cylinder.
Potential damage to a plated section may occur due to sparks if disregarded.
KEEP AWAY FROM FIRE
Always clean the parts with non-combustible cleaning agent or diesel fuel.
Keep the machine away from flame when using diesel fuel.
KEEP ATTACHMENT SURFACE CLEAN
Be sure to clean the attachment surface after removing a part to which the O-ring and gasket sealing
are attached.
Replace the part with a new one with the O-ring and gasket re-attached.
EMPTY YOUR POCKETS
Always empty your pockets before performing inspection and maintenance of the machine in a
downward direction with the cover opened.
INSPECT THE UNDERCARRIAGE
When performing crane operation in a rocky location, make sure of no damage to the undercarriage
and no looseness, cracks or abrasion of bolts and nuts. Loosen the tension of the crawler tread more
than usual.
PRECAUTIONS FOR MACHINE WASH
• Do not direct a jet of steam to the electrical parts and connector.
• Keep the operation panel dry. Especially be careful not to spray under the driving seat and around the
battery.
• Wash the machine with a clean cloth, rinsing off dirt and dust.
PRE- AND POST-WORK INSPECTION
Before performing crane operation in muddy water, rain, snow or on the coast, always check for loose
fitting plugs and valves. Post-operation inspection requires checks to all units for cracks and damage;
looseness and falling of bolts and nuts, after the machine has been washed.
Carry out early greasing. Grease the operating pin that enters the muddy water on a daily basis.
