Daily cleaning and inspection instructions
Verify inlet pressures
1. With gas flowing in the 004 diagnostic mode (Flow gas at full pressure), verify
that the pressure at each supply regulator is set to 6.2 bar (90 psi).
2. For complete instructions about setting supply regulators, see Setting the supply
gas regulators in your system’s instruction manual (807700).
Inspect all air filters
1. Inspect all air filters for moisture, oil, and particulates.
2. If moisture or oil is present, replace the air filter.
3. If a moderate amount of dust or other particulates is present, blow or
vacuum it out of the filter.
4. If there is a large build-up of dust or particulates, replace the air filter
(011093). Refer to Air filter element replacement in your system’s
instruction manual (807700) for replacement details.
Verify coolant level and condition
 Verify that the coolant tank is full. If the level is below the full line, add Hypertherm premixed
coolant (028872). Record the number of gallons your system requires in
Coolant requirements
on page 21.
 Inspect the coolant tank for dirt and particulates. If either are present:
1. Drain the tank. Locate the coolant drain valve and use a 20 liter (5 gallon) container to catch the
coolant. Coolant will flow as soon as the drain is opened.
2. Close the drain when the coolant stops flowing.
3. Fill the tank with clean coolant or water and run the pump to flush
the system.
4. Drain the tank again.
5. Refill the coolant tank to the full line with clean coolant.
6. Run the system to fill hoses and leads with coolant.
7. If necessary, add more coolant to the tank. Refer to Fill the power
supply with coolant in your system’s instruction manual (807700) for
more details.
