Environmental Safety - DeWalt DWE4557-XE Instruction Manual

4. Move the tool constantly in a straight line to
prevent burning and swirling of work
surface. Allowing the tool to rest on the
work surface without moving, or moving
the tool in a circular motion causes burning
and swirling marks on the work surface.
5. Remove the tool from work surface before turning tool off. Allow the wheel to
stop rotating before laying the tool down.
Precautions To Take When Sanding Paint
1. Sanding 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 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.
NOTE: Only those dust masks suitable for working with lead paint dust and fumes
should be used. Ordinary painting masks do not offer this protection. See your
local hardware dealer for the proper AS/NZS1716 approved mask.
3. NO EATING, DRINKING or SMOKING should be done in the work area to prevent
ingesting contaminated paint particles. Workers should wash and clean up
BEFORE eating, drinking or smoking. Articles of food, drink, or smoking should
not be left in the work area where dust would settle on them.

ENVIRONMENTAL SAFETY

1. Paint should be removed in such a manner as to minimize the amount of dust
generated.
2. Areas where paint removal is occurring should be sealed with plastic sheeting of
4 mils thickness.
3. Sanding should be done in a manner to reduce tracking of paint dust outside the
FIG. 15
work area.
CLEANING AND DISPOSAL
1. All surfaces in the work area should be vacuumed and thoroughly cleaned daily
5˚–15˚
for the duration of the sanding project. Vacuum filter bags should be changed
frequently.
2. Plastic drop cloths should be gathered up and disposed of along with any dust
chips or other removal debris. They should be placed in sealed refuse receptacles
and disposed of through regular trash pick-up procedures.
During clean up, children and pregnant women should be kept away from the
immediate work area.
3. All toys, washable furniture and utensils used by children should be washed
thoroughly before being used again.
Mounting and Using Wire Brushes and Wire Wheels
Wire cup brushes or wire wheels screw directly on the grinder spindle without the use
of flanges. Use only wire brushes or wheels provided with a M14 threaded hub. A
Type 27 guard is required when using wire brushes and wheels.
CAUTION: To reduce the risk of personal injury, wear work gloves when
handling wire brushes and wheels. They can become sharp.
CAUTION: To reduce the risk of damage to the tool, wheel or brush must not
touch guard when mounted or while in use. Undetectable damage could occur to the
accessory, causing wires to fragment from accessory wheel or cup.
MOUNTING WIRE CUP BRUSHES AND WIRE WHEELS
1. Thread the wheel on the spindle by hand.
2. Depress spindle lock button and use a wrench on the hub of the wire wheel or
brush to tighten the wheel.
3. To remove the wheel, reverse the above procedure.
NOTICE: To reduce the risk of damage to the tool, properly seat the wheel hub before
turning the tool on.
