Use clean oil and grease. Also, keep the containers of the oil and grease clean. Keep foreign materials away
from oil and grease.
CHECK DRAINED OIL AND USED FILTER
When replacing filters after oil is changed, check the old oil and filters for metal particles and foreign materials. If
large quantity of metal particles or foreign materials are found, always report to the person in charge, and per-
form suitable action.
PRECAUTIONS FOR REFILLING OIL OR FUEL

PRECAUTIONS FOR WELDING
• When conducting weld repair, turn the starting switch to OFF position and, after confirming that the system
operating lamp is turned off, set the battery disconnect switch key to OFF position and pull it out.
• Do not apply a voltage higher than 200 V continuously.
• Connect grounding cable within 1 m of the area to be welded.
If grounding cable is connected near instruments, connectors, etc., the instruments may malfunction.
• Prevent seals, bearings or bushings from entering the space between the weld zone and grounding point.
Seals and the like can cause damage to the nearby parts by catching fire from sparks.
• Do not connect the grounding cable around a pin or to a hydraulic cylinder.
Sparks generated there can damage the plated portion.
DO NOT DROP THINGS INSIDE MACHINE

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.
