GROUND FAULT CIRCUIT INTERRUPT (GFCI)
On HITACHI generator models (E43, E60, E71), all 20 Amp receptacles are protected by a
ground fault circuit interrupt (GFCI). The GFCI shuts off the power to the receptacle when
it senses small imbalances caused by current leakage to the ground.
REPLACEMENT PARTS
When servicing use only identical replacement parts.
Repairs should be conducted only by a Hitachi authorized service center.
USE PROPER EXTENSION CORD
Use only three-wire extension cords that have three-prong grounding-type plugs and three-pole receptacles
that accept your tool’s or appliance’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. Be sure to choose a cord that will supply enough voltage to
operate your tool or appliance. The tables below indicate appropriate guage for extension cords and the
voltage drop caused by the use of extension cords, given different electrical loads.
CAUTION:
Each GFCI should be tested for proper operation every time the
generator is used.
TO TEST A GFCI:
Start the generator. Turn the idle control switch (Fig.10-H) off. (See page10 for control
panel layout information.) Push in the TEST button on the receptacle. The RESET button
will pop out. Power is now off at the receptacle. If the RESET button does not pop out, the
GFCI is not working.
Do not run generator until the problem can be corrected. To restore power to receptacle,
push the RESET button in. If the RESET button pops out during operation, stop the
generator and check the generator and equipment for defects.

WARNING:
Avoid electrical shock hazard. Never use this generator with a damaged or frayed electrical
cord or extension cord.
Inspect all electrical cords regularly. Never use in or near water or in any environment where
electric shock is possible.
