Inspecting the leak proof o-ring and pressure relief valves

Use this procedure to inspect the leak proof o-ring and pressure relief valves.

NoteAction

DANGER

Turn off all:

• electric power supply

• hydraulic pressure supply

to the robot, before entering the robot work-

ing area.

DANGER

It is important to keep the pressure relief

valve open and clean. If the air pressure is

stopped up, too much pressure can be built

up which can be hazardous.

Check if the leak proof o-ring is contaminated

or covered with litter.

Clean if necessary.

Note

Use a cloth or a brush.
