CAUTION
Do not attach air tools to open end of the hose until start-up is com-
pleted and the unit checks out OK.
OPERATION AND ADJUSTMENT
1. The compressor is controlled by pressure switch when normal
working. It can be stopped automatically as pressure increasing to the
max and restart as pressure decreasing to the min. The rated pressure
has been adjusted when produced. Don’t change it carelessly. As
soon as motor switched off the compressed air in the discharge pipe
should be released through the release valve under the switch. This
is the necessary condition for restart, or the motor will be damaged.
The rated pressure can be adjusted by turning the adjusting bolt of the
switch (Fig.3).
2. The output pressure of compressed air can be adjusted by regulating
valve. Pull up the knob of regulation valve and turn it clockwise or
counterclockwise to increase or decrease the pressure (Fig.3).
3. The the compressor in running need be stopped only set the knob of
pressure switch in positing off.
