PRECAUTIONS FOR WELDING
• When conducting welding repair, turn the starting switch to OFF position, and wait for approximately 2 mi-
nute, and then disconnect the negative (-) terminal of the battery.
• Do not apply a voltage of 200 V and above continuously.
• Connect grounding cable within 1 m {within
3 ft 3 in} of the area to be welded. If grounding cable is connect-
ed near instruments, connectors, etc., the instruments may malfunction.
• Prevent seals, bearings or bushings from entering the space between the welding part and grounding part.
Sparks generated there can damage the seals.
• Do not use the area around the work equipment pins or the hydraulic cylinders as the grounding point.
Sparks generated there can damage the plated part.

drop nuts, bolts, or tools inside the machine.
If such things are dropped inside the machine, it may cause damage and/or malfunction of the machine,
and will lead to failure. If anything drops, be sure to take it out.
• Do not put unnecessary things in your pockets. Carry only things which are necessary for inspection.
