MAINTENANCE PROCEDURE
ROUTINE MAINTENANCE
1. Keep the cutting or gouging area and the area
around the machine clean and free of com-
bustible materials. No debris should be allowed
to collect which could obstruct air flow to the
machine.
2. Every few months, blow the dust off the air
intakes and louvers with compressed air. Also,
blow off the components in the upper compart-
ment with compressed air.
3. Check the air regulator filters to be sure they do
not become clogged. The first stage of the air
filter on the machine is self draining and will
stop most of the water in the air line. The sec-
ond stage of the filter is also self draining and
will stop almost all of the oil in the line as well as
particulate matter. Both stages will drain auto-
matically when the flow rate changes rapidly.
4. Check the filter elements every several months
to see if they are clogged (weekly in very dirty
environments). Replace if necessary.
5. Inspect the cable periodically for any slits or
puncture marks in the cable jacket. Replace if
necessary. Check to make sure that nothing is
crushing the cable and blocking the flow of air
through the air tube inside. Also, check for
kinks in the cable periodically and relieve any so
as not to restrict the flow of air to the torch.
ELECTRICAL SHOCK CAN KILL.
• Turn off machine at the disconnect switch at the
back of the machine before tightening, cleaning or
replacing consumables.
