Komatsu — Stopping Machine During Maintenance

SAFETY Stopping Machine During Maintenance To prevent personal injury, do not carry out maintenance with the engine running. If maintenance must be carried out with the engine running, see “Running the Machine During Maintenance” on page 1-38. Lower the work equipment completely to the ground and stop the engine before performing any inspection and maintenance. After stopping the engine, turn the starting switch to the ON position; operate work equipment control lever (1) two or three times to release the remaining pressure in the hydraulic circuit; then set work equipment lock lever (2) to LOCK position (L).

After releasing the remaining pressure in the hydraulic circuit, turn the starting switch to the OFF position. Set parking brake switch (3) to the ON position (A) to apply the parking brake. Put blocks in front of and behind the tires to prevent the machine from moving. 1-36 WA380-6
