SAFETY MEASURES DURING MAINTENANCE
PERSONNEL
Do not service or repair the machine unless you are an appropri-
ately qualified technician or have been appropriately instructed
by a qualified technician.
PRIOR TO START OF MAINTENANCE MEASURES
WARNING SIGN
While the machine is being serviced, the engine must not be
started and the control elements must not be actuated without
prior agreement, since this could cause accidents with serious
injury.
Always attach the warning sign to the control lever for the work
hydraulic system to warn other persons that work is being per-
formed on the machine. If required, put up additional warning
signs around the machine.
You may purchase these warning signs from your Komatsu deal-
er.
TOOLS
Only use tools which are suitable for the task you want to carry
out. If you use damaged or makeshift tools or tools which are of
inferior quality, injuries may occur.
SAFETY-RELATED PARTS
The quality of these parts is subject to normal wear and tear. For
this reason, replace safety-related parts by new ones at regular
intervals, regardless of whether they are defective or not.
Safety-related parts are:
Fuel system: fuel hose, overflow hose, and tank cap
Hydraulic system: all hydraulic hoses
Immediately replace defective parts, even if the interval for re-
placement has not elapsed.
Replace hydraulic hoses every 6 years.
