9. Breaking in the pump.
(1) Turn the knob of the pressure reducer fully clockwise to
open air fl ow.
(2) Place the knob of the pressure switch in the "OFF" position
and insert the plug into the receptacle.
(3) Open the drain cock completely.
(4) Turn the air compressor "ON (AUTO)" and run it for 10
minutes to break in the pump parts.
(5) Place the knob of the pressure switch in the "OFF"
position.
(6) Close the drain cock.

TRANSPORT

Turn off the pressure switch, and disconnect the plug from the
power source before transport the compressor.
Transport the compressor in the correct manner.
When transporting the compressor, grasp the handle.
WARNING
: Risk of unsafe operation. Ensure
proper footing and use caution when
carrying compressor to avoid a loss
of balance.

OPERATION

1. Start-up
Insert the plug into the receptacle and start the compressor
using the knob of the pressure switch. (Refer to Fig. 2).
WARNING
: Do not stop or start the compressor
by use of the plug. Always use "ON
(AUTO)/OFF"knob
pressure switch.
The operation of the compressor is automatic and is
controlled by the pressure switch which stops it when the
pressure in the air-tank reaches the maximum level and
restart it when the air pressure drops during use to the
restart level.
The motor has a thermal protector. The thermal protector
will stop the motor when the temperature is too high for any
reason.
The motor must be allowed to cool down before restarting.
CAUTION: Wear appropriate
protection
conditions and duration of use, noise from
this product may contribute to hearing loss.
2. Adjustment of outlet pressure
Adjust the outlet pressure to the required level by turning
the knob of the pressure reducer clockwise to increase the
outlet pressure and counterclockwise to decrease it.
A pressure gauge (B) is provided to show when the
required pressure is reached.
When adjusting the pressure, check and make sure that a
pressure gauge (A) for the tank has the pressure level that
is higher than that of the pressure to be adjusted.
It is also imperative that you make adjustment by slowly
starting up the pressure from the level that is lower than the
pressure to be adjusted.

3. Shutdown
(1) Place the knob of the pressure switch in the "OFF"
position. (Refer to Fig. 2).
(2) Unplug the plug from power source.
(3) Open the drain cock located at the lower part of the

: Check the manufacturer's maximum
pressure rating for nailers, staplers
and accessories. Compressor outlet
pressure must be regulated so as to
never exceed the maximum pressure
rating of the nailers, staplers and
accessories.
: Make sure the air fl ow to the pressure
reducer is completely
(the pressure gauge (B) attached
reads 0 psi) before attaching and
disconnecting the air
applications.

: Risk of bursting. When the tank
gets corroded, there is a risk of
breakdown. Water will
in the air tank. If not drained, water
will corrode and weaken the air tank
causing a risk of air tank rupture.
Drain tank daily or after 4 hours of
use. The drain contains moisture in
the air, abrasion particles, rust, etc..
To drain tank open valve slowly and
tilt compressor to empty accumulated
water. Keep face and eyes away from
