Inspection and maintenance of hydraulic device
1) Make sure to park the machine on a firm level ground when maintaining hydraulic system.
2) Lower bucket to ground, and stop engine.
3) Begin hydraulic system maintenance after parts, hydraulic oil, and lubricant have cooled down completely.
The hot parts or oil are likely to fly out or spark out and cause serious damage. When removing screw plug
or bolts, keep your body and face away from them. Because even if in the cooled condition, they may be
pressurized.
The hydraulic parts will be very hot
during operation. Please remember to
cool down excavator before inspection
or maintenance.
