GROUNDING INTRUCTIONS
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.

EXTENSION CORD

Use only three-wire extension cords that have three-prong grounding-type plugs and three-pole receptacles that accept the compressor's plug.
Replace or repair damaged cord.
Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your
product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table shows the correct size to
use depending on cord length and name plate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the
cord.
