2. Adjustment of working pressure
Unlock the knob of the pressure reducer pulling it up,
adjust the pressure to the required level by turning the
knob clockwise to increase and counterclockwise to
decrease.
A pressure gauge (B) is provided to know when the
required pressure is reached, lock the knob by pushing it
down fi rmly (Refer to Fig. 7).
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.
WARNING
: 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.
WARNING
: Regulate pressure to zero before
disconnecting hose.

WARNING
: Risk of bursting. When the tank
gets corroded, there is a risk of
breakdown.
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
drain cock.
4. About the thermal protector
The thermal protector operates to stop the motor when a
problem such as a motor overload, etc. occurs.
If the motor should stop during operation, proceed as
follows.
(1) Push the knob of the pressure switch to "OFF" and
disconnect the plug from the receptacle (Fig. 2).
(2) If the extension cord does not conform to the
specifi cations given on page 7 replace with an
extension cord such as that shown on page 7. If the
capacity of the power supply is insuffi cient, increase
the power supply capacity to remove the cause of a
fl ow of excessive current (over-current).
(3) Wait approximately 5 minutes.
(4) Start up. If the motor still stops during operation,
please contact the service center.
MAINTENANCE
WARNING
: Disconnect
the power source and remove the
compressed air from the air tank
before performing the maintenance
operations. Allow the compressor
to cool
maintenance operations.
1. Cleaning the intake fi lter
Remove the intake fi lter (Refer to Fig. 1) every 50 hours
or once a week and clean the inside of the intake fi lter
and the fi lter element with compressed air (Fig. 9). Use a
phillips screwdriver to disassemble intake fi lter.
WARNING
: Never clean fi lter element with a
fl ammable liquid or solvent.
CAUTION: Do not operate without the intake fi lter.
