2 – Routine Maintenance
Replace the air drying filter
1.
Turn OFF the system. Make sure the power switch on the front panel is in the OFF (
O
) position.
2.
Remove the service panel on the plasma side of the system.
3.
Slowly pull the pressure relief valve above
the air drying filter straight out approximately
5 mm (1/4 inch). Use the ring at the end of
the valve. This discharges internal pressure
from the air compressor.

Drain the air tank to release pressure. See
page 61.

Unscrew the air drying filter to remove it.
See
. Dispose of old filters in
compliance with local and national
regulations.

or other contaminants from the threads and mounting surface where the new filter will be installed.

Screw the air drying filter into place. Tighten by hand plus a 3/4 turn.
WARNING!
RISK OF INJURY – HANDLE COMPRESSED AIR WITH CARE
When servicing air compressor components:
Discharge internal pressure from the air compressor before performing
maintenance on any compressor parts. Trapped air pressure can discharge
violently and cause serious injury.
Do not inhale compressed air. Serious injury can result.
If air that was under pressure pierces your skin, seek medical treatment
immediately.
Never disable or disconnect any safety mechanisms for the air compressor.
Check all air compressor hoses and connections for leaks and damage before
operating the system again.
NOTICE
Replace the air drying filter regularly. When the cartridge inside an overused filter begins to
deteriorate, small pieces of the cartridge can get into the plasma cutting’s system air supply and
cause damage to the plasma supply.
