Double Insulation For Safer Operation - Hitachi WR 22SE Instruction Manual And Safety Instructions

Don't use tool for purpose not intended — for
example — don't use circular saw for cutting tree
limbs or logs.
10. NEVER use a power tool for applications other
than those specifi ed.
NEVER use a power tool for applications other than
those specifi ed in the Instruction Manual.
11. Handle tool correctly.
Operate the tool according to the instructions
provided herein. Do not drop or throw the tool.
NEVER allow the tool to be operated by children,
i n d i v i d u a l s u n fa m i l i a r w i t h i t s o p e ra t i o n o r
unauthorized personnel.
12. Keep all screws, bolts and covers tightly in
place.
Keep all screws, bolts, and plates tightly mounted.
Check their condition periodically.
13. Do not use power tools if the plastic housing or
handle is cracked.
Cracks in the tool's housing or handle can lead to
electric shock. Such tools should not be used until
repaired.
14. Blades and accessories must be securely
mounted to the tool.
Prevent potential injuries to youself or others. Blades,
cutting implements and accessories which have
been mounted to the tool should be secure and tight.
15. Keep motor air vent clean.
The tool's motor air vent must be kept clean so that
air can freely fl ow at all times. Check for dust build-up
frequently.
16. Operate power tools at the rated voltage.
Operate the power tool at voltages specified on its
nameplate.
If using the power tool at a higher voltage than the
rated voltage, it will result in abnormally fast motor
revolution and may damage the unit and the motor
may burn out.
17. NEVER use a tool which is defective or operating
abnormally.
If the tool appears to be operating unusually, making
strange noises, or otherwise appears defective, stop
using it immediately and arrange for repairs by a
Hitachi authorized service center.
18. NEVER leave tool running unattended. Turn
power off .
Don't leave tool until it comes to a complete stop.
19. Carefully handle power tools.
Should a power tool be dropped or struck against
hard materials inadvertently, it may be deformed,
cracked, or damaged.
20. Do not wipe plastic parts with solvent.
Solvents such as gasoline, thinner benzine, carbon
tetrachloride, and alcohol may damage and crack
plastic parts. Do not wipe them with such solvents.
Wipe plastic parts with a soft cloth lightly dampened
with soapy water and dry thoroughly.
21. ALWAYS wear eye protection that meets the
requirement of the latest revision of ANSI
Standard Z87.1.
22. When working in high places, check there is nobody
below. During operation, take care not to catch or
tighten the cord accidentally.
23. Switch the reversing switch only after the motor is
stopped when it is necessary to change the direction
of the rotation.
24. Use a step up transformer when a long extension
cable is used.
25. Confirm the tightening torque by a torque wrench
before use in order to ascertain the correct tightening
torque to be used.
26. Attach the hex. socket securely onto the anvil. If the
hex. socket is insuffi ciently secured, it may drop out
and cause an accident. For hex. socket attachment
refer to "PRIOR TO OPERATION" on page 8.
27. Confi rm whether the socket has any crack in it.
28. Defi nitions for symbols used on this tool

A .................amperes
n ...............no load speed
o
W ................watt

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 from the outer
frame handled by the operator. Therefore, either the
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:
○ Only HITACHI AUTHORIZED SERVICE CENTER
should disassemble or assemble this power tool, and
only genuine HITACHI replacement parts should be
installed.
○ 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.
