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 N.I.O.S.H.
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
work area.
CLEANING AND DISPOSAL
1. All surfaces in the work area should be
vacuumed and thoroughly cleaned daily
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
12
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 5/8 inch-11
threaded hub. A Type 27 guard is required
when using wire brushes and wheels.
Wear work gloves when handling wire
brushes and wheels. They can become
sharp.
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
Turn off tool and remove battery before
making any adjustments or removing or
installing attachments or accessories.
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.
Failure to properly seat the wheel hub before
turning the tool on may result in damage to
tool or wheel.
USING WIRE CUP BRUSHES AND WIRE
WHEELS
Wire wheels and brushes can be used for
removing rust, scale and paint, and for
smoothing irregular surfaces.
NOTE: The same precautions should be
taken when wire brushing paint as when
sanding paint (see page 12).
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. Apply minimum pressure to work
surface, allowing the tool to operate at
high speed. Material removal rate is
greatest when the tool operates at high
speed.
3. Figure N - Maintain a 5 ° to 10 ° angle
between the tool and work surface for
wire cup brushes.
4. Maintain contact between the edge of
the wheel and the work surface with
wire wheels.
5. Continuously move the tool in a forward
and back motion to avoid creating
gouges in the 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.
6. Remove the tool from the work surface
before turning the tool off. Allow the tool
to stop rotating before setting it down.
Use extra care when working over an edge,
as a sudden sharp movement of grinder
may be experienced.
CLEANING
Blowing dust and grit out of the motor
housing using compressed air is a
necessary maintenance procedure. Dust
and grit from metal grinding often
accumulate on interior surfaces and could
create an electrical shock hazard if not
cleaned out.
,4, WARNING: ALWAYS use safety
glasses. Everyday eyeglasses are NOT
safety glasses. Also use face or dust mask
if operation is dusty. ALWAYS WEAR
CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA
Z94.3),
• ANSI $12.6 ($3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory
protection.
Use only mild soap and a damp cloth to
clean the tool. Never let any liquid get
inside the tool; never immerse any part of
the tool into a liquid.
IMPORTANT: To assure product SAFETY
and RELIABILITY, repairs, maintenance
and adjustment (other than those listed in
this manual) should be performed by
authorized service centers or other
qualified service personnel, always using
identical replacement parts.
LUBRICATION
Craftsman tools are properly lubricated at
the factory and are ready for use. Tools
should be lubricated regularly every year
depending on usage. (Tools used on heavy
duty jobs and tools exposed to heat may
require more frequent lubrication.) This
lubrication should be attempted only by
trained power tool repair specialists such
as those at Sears Service Centers or in
other qualified service organizations.
