GROUNDING INSTRUCTIONS
This compressor should be grounded while in use to protect the
operator from electric shock. The compressor is equipped with a
three-conductor cord and three-prong grounding type plug to fit the
proper grounding type receptacle. The green (or green and yellow)
conductor in the cord is the grounding wire. Never connect the
green (or green and yellow) wire to a live terminal. If your unit is for
use on less than 150 volts, it has a plug that looks like that shown in
sketch (A) in Figure on the right. An adapter, see sketches (B) and
(C), is available for connecting sketch (A) type plugs to two-prong
receptacles. The green-colored rigid ear, lug, or the like extending
from the adapter must be connected to a permanent ground, such
as a properly grounded outlet box.
NOTE: The grounding adaptor, sketch (C), is prohibited in Canada
by Canadian Electrical Code Part 1. Therefore, the
instructions for its use are not applicable in Canada.
We recommend that you never disassemble the compressor or try
to do any rewiring in the electrical system. Any repairs should be
performed only by HITACHI Service Centers or other qualified
service organizations. Should you be determined to make a repair
yourself, remember that the green colored wire is the “grounding”
wire. Never connect this green wire to a “live” terminal. If you
replace the plug on the power cord, be sure to connect the green
wire only to the grounding (longest) prong on a 3-prong plug.
If in doubt, call a qualified electrician and have the receptacle
checked for ground.

4. Shutdown
(1) To stop the air compressor, move the Motor/
Pressure switch to the “OFF” position. Never stop
the air compressor by unplugging it from the
power source. This could result in risk of
electrocution.
(2) To drain the air tank open the drain valve slowly
and tilt compressor to empty accumulated water.
WARNING: When the air tank gets corroded, there is
a risk of breakdown. Accordingly, be sure
to discharge the drain inside the air tank
after each use.
The drain contains moisture in the air,
abrasion particles, rust, etc. To discharge
the drain, therefore, gradually open the
drain valve, and be careful not to point it
at your face or eye.
