6. SWITCHING THE COMPRESSOR ON
(Fig.5)
Switch on the compressor at the pressure switch (2) by turning the knob (3)
to position “I.”, The compressor sends pressurized air to the air tank. As
the compressed air is used, the pressure in the air nozzle drops to a preset
level, the compressor switches on and the air nozzle files with compressed
air. After reaching the cutoff pressure the compressor turns off
automatically and the cycle is repeated. Check the value of switching-on
and switching-off pressure on pressure gauge. The values may be within a
tolerance of
10%. Air pressure in air chamber must not exceed maximal
permitted operation pressure.
Never tamper with the pressure switch (2). Adjustments are not allowed. The pressure
switch (2) has been set by the manufacturer and further setting of switching on and off
pressure may be carried out only by a qualified expert trained by the manufacturer.
