WARNING
ELECTRIC SHOCK CAN KILL.
BEFORE PERFORMING ANY MAINTE- NANCE THAT REQUIRES OPENING THE CASE OF THE POWER SOURCE:
•Disconnect input power to this machine at the Disconnect switch.
•Do not touch electrically live parts or internal wiring.
•Only qualified personnel should service this machine.
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.
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.
WARNING
ELECTRICAL SHOCK CAN KILL.
Turn off machine at the disconnect switch at the back of the machine before tightening, cleaning or replacing consumables.
Change consumables as required.

HOW TO USE THIS GUIDE: Carefully read through each applicable section listed on the following pages. Remember that most problems are caused by improp- er setup, such as switch settings, control settings, etc.
If you believe the set up is correct and the trouble still exists, first check for the obvious: input power, blown fuses, loose PC board connectors, broken wires and the like. The sections listed on the following pages are intended to help you find the less obvious sources of trouble.
TROUBLESHOOTING GUIDE
Visual Inspection
Clean interior of machine with a low pressure airstream. Make a thorough inspection of all compo- nents. Look for signs of overheating, broken leads or other obvious problems. Many problems can be uncovered with a good visual inspection.
After the visual inspection proceed to the proper symptom section of this guide for necessary checks to perform.
