Environmental Safety - DeWalt DWE402 Instruction Manual

1. Allow the tool to reach full speed before touching the
tool to the work surface.
2. Apply minimum pressure to the work surface, allowing
the tool to operate at high speed. Material removal rate
is greatest when the tool operates at high speed.

3. Maintain an appropriate angle between the tool
and work surface. Refer to the chart according to
particular function.
Function
Grinding
Sanding with Flap Disc
Sanding with Backing Pad
Wire Brushing
4. Maintain contact between the edge of the wheel and
the work surface.
- If grinding, sanding with flap discs or wire brushing
move the tool continuously in a forward and
back motion to avoid creating gouges in the
work surface.
- If sanding with a backing pad, move the tool
constantly in a straight line to prevent burning and
swirling of work surface.
nOTE: Allowing the tool to rest on the work surface without
moving will damage the work piece.
5. Remove the tool from work surface before turning tool
off. Allow the tool to stop rotating before laying it down.

CAUTION: Use extra care when working over an
edge, as a sudden sharp movement of grinder may
be experienced.
Precautions To Take When Working on
a Painted Workpiece
1. Sanding or wire brushing of lead based paint is NOT
RECOMMENDED due to the difficulty of controlling
the contaminated dust. The greatest danger of lead
poisoning is to children and pregnant women.
2. Since it is difficult to identify whether or not a paint
contains lead without a chemical analysis, we
recommend the following precautions when sanding
any paint:
Personal safety
1. No children or pregnant women should enter the work
area where the paint sanding or wire brushing is being
done until all clean up is completed.
2. A dust mask or respirator should be worn by all persons
entering the work area. The filter should be replaced
daily or whenever the wearer has difficulty breathing.
3. NO EATING, DRINKING or SMOKING should be done in

children should be washed thoroughly before being
used again.
WARNING: Do not use edge grinding/cutting wheels
for surface grinding applications because these wheels
are not designed for side pressures encountered
with surface grinding. Wheel breakage and injury
may result.
CAUTION: Wheels used for edge grinding and cutting
may break or kick back if they bend or twist while
the tool is being used. In all edge grinding/cutting
operations, the open side of the guard must be
positioned away from the operator.
NOTICE: Edge grinding/cutting with a Type 27 wheel
must be limited to shallow cutting and notching—
less than 13 mm in depth when the wheel is new.
Reduce the depth of cutting/notching equal to the
reduction of the wheel radius as it wears down. Refer
to the Accessories Chart for more information. Edge
grinding/cutting with a Type 41 wheel requires usage
of a Type 1 guard.
