Remove the Air Valve Head, and pass a wire that has been bent like a hook
through the exhaust port to raise the Air Valve to remove it.

Apply grease to the O-ring of
the Air Valve.
ە
Recommended grease is Grease grade 1~2.
ە
When removing the Air Valve, be careful not to damage the O-ring with the wire.

Before starting maintenance or disassembling the unit to replace parts, be sure to stop air
supply.
Performing maintenance or disassembly with air supplied may cause a part to jump out, oil to squirt
out, or the unit to perform unexpected behavior, and may result in an accident or personal injury.

Avoid skin contact with substances such as hydraulic oil, lubricating oil and grease.
Such substances may cause inflammation of the skin. If they come into contact with your skin, wash
the affected area thoroughly.
CAUTION
Turn off the air supply.
Remove
cross recessed pan head screws (2 pieces) and tapping screws (3 pieces)
