Precautions For Maintenance; Before Carrying Out Maintenance - Komatsu 730E Operation & Maintenance Manual

OM2026.1
General Safety

BEFORE CARRYING OUT MAINTENANCE

WARNING TAG
• If others start the engine or operate the controls while you are performing service or lubrication, you could
suffer serious injury or death.
• ALWAYS attach the WARNING TAG to the control lever in the operator's cab to alert others that you are
working on the machine. Attach additional warning tags around the machine, if necessary.
• These tags are available from your Komatsu distributor. (Part No. 09963-03000)
PROPER TOOLS
• Use only tools suited to the task. Using damaged, low quality, faulty, or
makeshift tools could cause personal injury.
PERIODIC REPLACEMENT OF CRITICAL PARTS
• Periodically replace parts used to insure safety or prevent accident.
• Replace these components periodically with new ones, regardless of whether or not they appear to be
defective. These components deteriorate over time.
• Replace or repair any such components if any defect is found, even though they have not reached the time
specified.
STOPPING THE ENGINE BEFORE SERVICE
• When carrying out inspection or maintenance, always stop the machine on firm flat ground, lower the dump
body, then stop the engine.
• If the engine must be run during service, such as when cleaning the radiator, always set the shift selector lever
to the neutral (N) position and the parking brake lever to the PARKING position. Always carry out the work with
two people. One person should sit in the operator's seat so that the engine can be stopped, if necessary.
NEVER move any controls not needed for operation.
• When servicing the machine, be careful not to touch any moving part or get clothing caught.
• Put blocks under the wheels.
• When carrying out service with the dump body raised, always place the dump lever at the HOLD position, and
insert the body-up safety pins (or safety cable, if equipped) securely.
