Maintenance
Pressure Release Valve
•
The safety valve is designed to release any excess pressure and to let you release the
pressure after spraying.
•
Do not interfere with the setting of the air pressure safety valve.
Plunger Head

The O-Ring should be kept lubricated to slide freely in the barrel and so pump air
efficiently.
•
To apply grease proceeds as follows.
•
Remove the pumps assembly by unscrewing in an anti-clockwise direction.
•
Locate the pump handle into the carrying position and grip the barrel.
•
Unscrew the plunger retaining cap from the pump barrel by rotating the handle.

Withdraw the plunger and apply silicone grease to the O-Ring.
•
When re-assembling ensure the O-Ring is not trapped between the outer edge of the
plunger moulding and the inside of the pump barrel.
