MAINTENANCE
Gas Console
• Check the exterior for any damage. If there is damage, ensure it does not affect safe operation of the
console.
• Inspect all interconnecting cables, hoses and leads for wear and damage. Check that connections are tight
but do not overtighten.
• Inspect the air filter. Replace the filter when it gets dirty.
• Remove cover and inspect the interior:
– Check wiring harnesses and connections for wear and damage. Check for loose connections. The
solenoid valves operate hot and discoloration is normal.
– Check for dust and foreign matter inside the unit. Blow out the unit with compressed air. In an excessively
dirty environment, do this weekly.
Torch, Quick Disconnect/Off-Valve and Torch Leads Inspection
• Inspect the torch main body O-rings and replace, if necessary.
• The torch consumable parts and torch main body should always be inspected prior to cutting. Worn or
damaged parts can cause gas and water leaks which can affect the cut quality. Check for pitting and burn
marks on the consumable parts and replace, if necessary. Refer to Section 4, Changing Consumable Parts.
• Ensure that all connections are tight, but do not overtighten.
• Inspect the torch leads for cracking and damage. Replace if necessary.
