PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized conforms
to the power source requirements specified on the
product nameplate.
2. Power switch
Ensure that the knob of the pressure switch is in the
"OFF" position. If the plug is connected to a
receptacle while the knob is in the "AUTO" position,
the compressor will start operating immediately and
can cause serious injury.
3. Extension cord
When the work area is far away from the power
source, use an extension cord of sufficient thickness
and rated capacity (refer page 6). The extension cord
should be kept as short as practicable.
WARNING:
Damaged cord must be replaced or
repaired.
4. Confirm the power receptacle
If the power receptacle only loosely accepts the plug,
the receptacle must be repaired. Contact the nearest
electric store for repair service.
If such a faulty receptacle is used, may cause
overheating, resulting in a serious hazard.
5. Dipstick insertion and oil level check
(If your compressor is EC6C this step is not
necessary.)
Use a screwdriver or similar tool to remove the plastic
cap on the lower part of the cylinder (Fig. 2).

When the oil volume is insufficient, refer to the section
"Oil change-oil topping off" on page 12 for a descrip-
tion of how to supply the oil.
6. Air coupler installation
Screw in the air coupler to the joint (Refer to Fig. 1
and Fig. 4.). The screw size of the joint is 3/8". Use an
air coupler which has the same screw size.

OPERATION

1. Start up
Insert the plug into the receptacle and start the
compressor by turning the knob of the pressure
switch, to "AUTO". (Refer to Fig. 1 and Fig. 4).
WARNING:
Do not stop or start the compressor
by use of the plug. Always use
"AUTO/OFF" knob located on the
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 of the compressor is fitted with a thermal
protection inside-the wrap, which stops the
compressor when the temperature is too high. Should
this be tripped, the compressor will restart automati-
cally after 15–20 minutes.
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 is provided to know when the
required pressure is reached, lock the knob by
pushing it down firmly (Fig. 4).
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.
