Double Insulation For Safer Operation - Metabo HPT G 12SR4 Manual De Instrucciones

8. 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.
9. 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,
individuals unfamiliar with its operation or
unauthorized personnel.
10. Keep all screws, bolts and covers tightly in
place.
Keep all screws, bolts, and plates tightly mounted.
Check their condition periodically.
11. 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.
12. Blades and accessories must be securely mounted
to the tool.
Prevent potential injuries to yourself or others.
Blades, cutting implements and accessories which
have been mounted to the tool should be secure and
tight.
13. 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.
14. 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.
15. 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
metabo HPT authorized service center.
16. NEVER leave tool running unattended. Turn
power off .
Don't leave tool until it comes to a complete stop.
17. Carefully handle power tools.
Should a power tool be dropped or struck against
hard materials inadvertently, it may be deformed,
cracked, or damaged.
18. 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.
19. NEVER use a depressed center wheel which
is cracked or deformed or worn away (see the
MAINTENANCE AND INSPECTION section on page
12).
20. NEVER use the grinder in places where the sparks
generated by the grinder can cause explosion, such
as where fl ammable materials or gases are present.
21. NEVER push in the push button while the spindle is
running.
22. ALWAYS wear eye protection that meets the
requirement of the latest revision of ANSI
Standard Z87.1.
23. ALWAYS wear a mask or respirator to protect
yourself from dust or potentially harmful particles
generated during the grinding operation.
24. ALWAYS fi rmly grip the body handle and side handle
while operating the grinder.
25. ALWAYS have a trial run before grinding commence.
(see Test the grinder before using on page 10).
26. ALWAYS follow the instructions contained in this
manual when replacing the depressed center wheel.
27. ALWAYS be careful with buried object such as an
underground wiring.
Touching these active wiring or electric cable with
this tool, you may receive an electric shock.
Confi rm if there are any buried object such as electric
cable within the wall, fl oor or ceiling where you are
going to operate here after.

DOUBLE INSULATION FOR SAFER
OPERATION
To ensure safer operation of this power tool, metabo HPT
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:
