The jets of high pressure liquids
can penetrate skin and cause
serious damage.
The leakage of hydraulic oil and lubricant can cause fire and damage of human body,
in order to prevent this danger:
 Park the excavator on a firm level ground.
 Lower the bucket to ground.
 Idle the engine for 5 minutes.
