USE OF EXTENSION 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 nameplate
ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the
heavier the cord.
MINIMUM GAGE FOR CORD SETS

DOUBLE INSULATION FOR SAFER OPERATION
To ensure safer operation of this power tool, HITACHI has adopted a double insulation
design. “Double insulation “means that two physically separated insulation systems have
been used to insulate the electrically conductive materials connected to the power supply
fromthe outer framehandled bythe operator.Therefore, eitherthe symbol “”or the words
“Double insulation”appear on the power tool or on the nameplate.
Although this system has no external grounding, you must still follow the normal electrical
safety precautions given in this Instruction Manual, including not using the power tool in wet
environments.
To keep the double insulation system effective, follow these precautions:
䡬Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble this
power tool, and only genuine HITACHI replacement parts should be installed.
䡬Clean the exterior of the power tool only with a soft cloth moistened with soapy water,
and dry thoroughly.
Never use solvents, gasoline or thinners on plastic components; otherwise the plastic
may dissolve.
