SAFETY
PRECAUTIONS FOR MAINTENANCE
STOP ENGINE BEFORE CARRYING OUT INSPECTION AND MAINTENANCE
Lower the work equipment completely to the ground and stop
the engine before performing any inspection and maintenance.
Turn the starting switch to the ON position. Operate the work
equipment control lever back and forth, left and right at the full
stroke 2 to 3 times to eliminate the remaining internal pressure
in the hydraulic circuit, and then move lock lever (1) to the LOCK
position (L).
Check that the battery relay is off and main power is not
conducted. (Wait for approx. one minute after turning off the
engine starting switch key and press the horn switch. If the horn
does not sound, it is not activated.)
Put blocks under the track to prevent the machine from moving.
