Air Filters
Clean the air filters. Remove the filter end cover [c], wash the air intake filter [b] using a light detergent, and
dry it thoroughly before re-installing. Replace the air delivery filter [a] once a year.
Ignition Electrodes
Clean, adjust and, if necessary, replace the ignition electrodes.
Compressor Pressure Adjustment
The compressor pressure is factory-set and must be checked and adjusted by
qualified technicians only. Tampering with the unit may be dangerous.
Remove the pressure gauge cap [a]. Connect a pressure gauge on the pressure measuring port on the rear
guard. Start the device and read the air pressure value. If necessary, adjust the pressure to the correct value
turning the adjusting screw (the air vent hole [b]) clockwise to increase, or anticlockwise to decrease the
pressure.
Electrical
Inspect all cables, electrical parts and connections.
