PRECAUTIONS FOR MAINTENANCE SAFETY
2-34
KEEP WORKPLACE CLEAN AND TIDY
q Do not leave hammers or other tools lying around in the work place. Wipe up all grease, oil, or other sub-
stances that will cause you to slip. Always keep the work place clean and tidy to enable you to carry out oper-
ations safely.
If the work place is not kept clean and tidy, there is the danger that you will trip, slip, or fall over and injure your-
self.
q When cleaning the ceiling window which is made of organic glass (polycarbonate), use tap water and avoid
use of organic solvents for cleaning. An organic solvent like benzene, toluene or methanol can invite a chemi-
cal reaction like dissolution and decomposition on the window glass, deteriorating polycarbonate in use.
SELECT SUITABLE PLACE FOR INSPECTION AND MAINTENANCE
q Stop the machine on firm, level ground.
q Select a place where there is no hazard of landslides, falling rocks, or flooding.
STABILITY
When dismantling or assembling the machine for the purpose of maintenance, repair or transportation, always
ensure that at each stage of the process, care is taken to ensure that the machine remains stable. Failure to do
this could result in serious injury or death.
GUARDS
Guards are installed in the area of the engine to protect personnel from moving parts. These guards should only
be removed by a Komatsu service engineer unless specific instructions are given in this manual.
ONLY AUTHORIZED PERSONNEL
Do not allow any unauthorized personnel into the area when servicing the machine. If necessary, employ a guard.
APPOINT LEADER WHEN WORKING WITH OTHERS
q When repairing the machine or when removing and installing the work equipment, appoint a leader and follow
his instructions during the operation.
