GUARDS
• Guards are installed in the area of the engine to protect personnel from moving parts. These guards should
only be removed by Komatsu service engineer unless specific instructions are given in this manual.
END OF SERVICE LIFE
• For safe dismantling of the machine at the end of service life, please contact your Komatsu distributor.
STOP ENGINE BEFORE CARRYING OUT INSPECTION AND MAINTENANCE
If you are caught or pinched between the work equipment during operation, or exposed to high-temperature or
high-pressure liquids, it is dangerous and may cause serious personal injury or death. Always observe the fol-
lowing.
• Lower the work equipment to the ground and stop the en-
gine before performing any inspection and maintenance.
• Stop the engine (work equipment is lowered to the
ground), and turn the starting switch to ON position. Press
the work equipment lock switch (2) to release the work
equipment lock (the pilot lamp goes off), then operate the
multifunction mono-lever (1) to RAISE and LOWER posi-
tion fully 2 to 3 times to release the remaining pressure in
the hydraulic circuit. Then lock the work equipment (the pi-
lot lamp lights up) by pressing the work equipment lock
switch (2).
After releasing the remaining pressure in the hydraulic cir-
cuit, turn the starting switch to OFF position.
• Set parking brake switch (3) to ON (operation) position (A)
to apply the parking brake, then put blocks in front of and
behind the tires to prevent the machine from moving.
