Double Insulated Tools; Important - Bosch 1347A Manual Del Usuario

• Before using a grinder or installing a new
wheel, inspect the grinding wheel for chips and
cracks. Remove bad wheels immediately. Run
the tool at no load for one minute, holding the
tool in the direction away from people. Wheels
with flaws will normally break apart during this
time.
• Carefully handle both the tool and individual
grinding wheels to avoid chipping or cracking.
Inspect grinding wheel before using. Do not use
a grinding wheel that is cracked. If tool is
dropped while grinding, install a new wheel. Do
not use a wheel that may be damaged.
• Grinding wheels or any other accessory must
have a maximum safe operating speed greater
than the "no load RPM" marked on the tool's
nameplate.
• Do not use grinding wheel that is larger than
the maximum recommended size for your tool,
or worn down damaged wheels from larger grind-
ers.
• Do not use depressed hub grinding wheels for
cut-off operations.
• Do not use this tool with "Woodcarving"
blade, such blades create frequent kick-back and
loss of control.
• Proper apparel while using a grinder includes:
face shield or at least safety goggles, dust mask,
leather gloves and shop apron capable of stop-
ping small wheel or work piece fragments.
• Keep cord away from the grinding wheels or
any other sanding accessory.
• Avoid bouncing and snagging the wheel, es-
pecially when working corners, sharp edges etc.
This can cause loss of control and kick-back.
• Clean the tool's air vents by compressed air or
excessive accumulation of powdered metal in-
side the motor housing
failures.
• Do not grind or sand near flammable materi-
als, as sparks from the wheel could ignite these
materials.
• The grinding wheel guard cannot be used for
most sanding operations or for wire brushing.
When grinding is resumed, wheel guard must be
reinstalled on the tool.
• When sanding, do not use oversized sanding
disc. Larger sanding disc will extend beyond the
sanding pad causing snagging, tearing of the disc
or kick-back. Extra paper extending beyond the
sanding pad can also cause serious lacerations.
• When sanding chemically pressure treated
lumber, paint that may be lead based, or any

other materials that may contain carcinogens,
use special precautions. A suitable breathing
respirator must be worn by all personnel entering
the work area. Work area should be sealed by
plastic sheeting and persons not protected should
be kept out until work area is thoroughly cleaned.
WARNING! Some dust created by power
sanding, sawing, grinding, drilling, and other
construction activities contains chemicals
known to cause
cancer, birth defects or other reproductive harm.
Some examples of these
chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement and
other masonry products, and
• Arsenic and chromium from chemically treated
lumber.
Your risk from these exposures varies, depend-
ing on how often you do this type of work. To
reduce your exposure to these chemicals: work
in a well ventilated area, and work with ap-
proved safety equipment, such as those dust
masks that are specially designed to filter out
microscopic particles.
• Double Insulation
used in electric power tools which eliminates
the need for the three wire grounded power cord
and grounded power supply system. It is a
recognized and approved system by
Underwriter's Laboratories, CSA and Federal
OSHA authorities.

IMPORTANT:

double insulation requires care and knowledge
of the system and should be performed only by
a qualified service technician. WHEN SER-
VICE IS REQUIRED USE ONLY IDENTI-
CAL REPLACEMENT PARTS.
POLARIZED PLUGS: If your tool is equipped
with a polarized plug (one blade is wider than
the other), this plug will fit in a polarized outlet
only one way. If the plug does not fit fully in the
outlet, reverse the plug. If it still does not fit,
contact a qualified electrician to install the
proper outlet. To reduce the risk of electric
shock do not change the plug in any way.
