Transport; Operation - Hitachi EC119 OM Safety And Instruction Manual

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
Use a screwdriver or similar tool to remove the plastic
cap on the lower part of the cylinder (Fig. 3).
Plastic cap
Insert the accessory dipstick all the way to the bottom.
Remove the dipstick and make sure the oil level is
within the range of the dipstick notches (Fig. 4).
Air vent
WARNING:
Drain tank to release air pressure
before removing the dipstick.
WARNING:
Make sure air vent in dipstick is free
from debris. If air vent is blocked
pressure can build in crankcase
causing damage to compressor and
possible personal injury.
When the oil volume is insufficient, refer to the section
"Oil change-oil topping off" on page 13 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. 6). The screw size of the joint is 3/8". Use an
air coupler which has the same screw size.
7. Right running position
Position the compressor on a flat surface or one with
an inclination of 10º at the most, in a well ventilated
area away from atmospheric agents and not in
explosive areas (Fig. 5).
CAUTION :

TRANSPORT

Push the knob of the pressure switch to "OFF" and
disconnect it from the power source before move the
compressor. Transport the compressor in the correct
manner.

OPERATION

1. Start up
Insert the plug into the receptacle and start the
compressor by pulling the knob of the pressure switch
to "ON" (Refer to Fig. 2).
WARNING:
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 with manual reset (push-button), which
stops the compressor when the temperature is too
high. Should this be tripped, the compressor will
restart only if reset is done.
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 firmly (Refer to Fig. 6).
— 11 —
In order to avoid damaging the
compressor, do not allow the unit to
be tilted more than 10º when
operating.

Do not stop or start the compressor
by use of the plug. Always use "ON/
OFF" knob located on the pressure
switch.
