The Label On Your Tool May Include The Following Symbols - DeWalt DW400 Instruction Manual

• Do not use Type 11 (flaring cup) wheels on this tool. Using
inappropriate accessories can result in injury.
• Before using, inspect recommended accessory for cracks
or flaws. If such a crack or flaw is evident, discard the
accessory. The accessory should also be inspected when-
ever you think the tool may have been dropped. Flaws may
cause wheel breakage.
• When starting the tool with a new or replacement wheel, or
a new or replacement wire brush installed, hold the tool in
a well protected area and let it run for one minute. If the
wheel has an undetected crack or flaw, it should burst in less
than one minute. If the wire brush has loose wires, they will be
detected. Never start the tool with a person in line with the
wheel. This includes the operator.
• Avoid bouncing the wheel or giving it rough treatment. If this
occurs, stop the tool and inspect the wheel for cracks or flaws.
• Direct sparks away from operator, bystanders or flammable
materials. Sparks may be produced while using a sander or
grinder. Sparks may cause burns or start fires.
• Always use side handle. Tighten the handle securely. The
side handle should always be used to maintain control of the tool
at all times.
• Clean out your tool often, especially after heavy use. Dust
and grit containing metal particles often accumulate on interior
surfaces and could create an electric shock hazard.
CAUTION: Type 1 Abrasive and Diamond Cut-Off Wheels may
not be used on this tool. A Type 1 Cut-Off Wheel Guard is not avail-
able for the DW400.

CAUTION: Use extra care when grinding into a corner as a
sudden, sharp movement of the grinder may be experienced
when the wheel contacts a secondary surface.
CAUTION: Wear appropriate personal hearing protection
during use. Under some conditions and duration of use, noise
from this product may contribute to hearing loss.
WARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains chem-
icals 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
(CCA).
Your risk from these exposures varies, depending 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 approved safety equip-
ment, such as those dust masks that are specially designed to
filter out microscopic particles.
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction
activities. Wear protective clothing and wash exposed
areas with soap and water. Allowing dust to get into your
mouth, eyes, or lay on the skin may promote absorption of
harmful chemicals.
