• While disassembling connector or plug or disconnecting hose, stand on one side, loosen
slowly to gradually relieve internal pressure, and then take out.
• The engine oil or oil plug may spray out under the internal pressure of traveling motor oil
tank. Please slowly loosen the oil plug to relieve the internal pressure.
Guard against Splashed Fragments during Use of Hammer

personal harm.
• While hammering hard metal parts such as pins, bucket teeth, side teeth, and bearings,
please wear protective articles including goggles and gloves.
• While hammering pins and bucket teeth, ensure there is no person in surrounding area.
