When opening valve
5
, be aware that the air-supplied mechanism is partly activated.
If the air supply source pulse is too large, even at the above setting value the emergency
signal might go off.

ng tape or the lke round
the screw.
2) Insert ar hose

and fasten them
wth hose band

.
(Use the correct ar hose
to match the fitting.)
(2) connecting the air gun
Insert the col tube of ar gun

and put the ar gun on
L-shaped fitting

.
(3) opening/closing the valve
To open/close valve
5
, turn the valve untl t wll go no further (by 90 degrees of an
angle).
(4) adjusting the supply air pressure
) The operatng ar pressure should be set to 0.5 MPa.
2) Delberately open valve

.
3) Lft regulator knob

. Turnng t n ths state wll change the sup-
ply ar pressure. Turn knob n drecton

(+) or n drecton
D
(–) so that black
pont of pressure gauge

to securely lock t.
(5) Pressure drop signal adjustment
) Set the pressure at whch an emergency sgnal wll go off f the pressure drops below t.
2) The normal settng value s 0.4 MPa.
3) Insert a small screwdrver nto cap
!1
of pressure gauge
!0
, and adjust screw

whch s nsde. Turn the
screw wth the screwdrver untl the green ponter ponts to 0.4 MPa.
(6) Discharging the drainage
) Remove the dran from regulator before use to dscharge water (by loosenng knob
!3
).
2) Water adversely affects the ar control components. It s therefore necessary to carefully remove the water.
3) If the ar pressure n regulator drops, the pressure gauge swtch comes on to cause an error.
