Metal Applications
When using the tool in metal applications, make sure that a
residual current device (RCD) has been inserted to avoid residual
risks caused by metalswarf.
If the power supply is shut off by the RCD, take the tool to an
authorised D
EWALT repairagent.
WARNING: In extreme working conditions, conductive
dust can accumulate inside the machine housing when
working with metal. This can result in the protective
insulation in the machine becoming degraded with a
potential risk of an electricalshock.
Edge Grinding and Cutting
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 mayresult.
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
theoperator.
NOTICE: Edge grinding/cutting with a Type27wheel
must be limited to shallow cutting and notching—less
than 13mm 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 Accessory
Chart for more information. Edge grinding/cutting with a
Type 41wheel requires usage of a Type 1guard.
1. Allow the tool to reach full speed before touching the tool
to the worksurface.
2. Apply minimum pressure to the work surface, allowing
the tool to operate at high speed. Grinding/cutting rate is
greatest when the tool operates at highspeed.
3. Position yourself so that the open-underside of the wheel is
facing away fromyou.
4. Once a cut is begun and a notch is established in the
workpiece, do not change the angle of the cut. Changing
the angle will cause the wheel to bend and may cause
wheel breakage. Edge grinding wheels are not designed to
withstand side pressures caused bybending.
5. Remove the tool from the work surface before turning the
tool off. Allow the tool to stop rotating before laying itdown.
4. Maintain contact between the edge of the wheel and the
worksurface.
‑ 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 worksurface.
‑ If sanding with a backing pad, move the tool constantly
in a straight line to prevent burning and swirling of
worksurface.
NOTE: Allowing the tool to rest on the work surface without
moving will damage the workpiece.
5. Remove the tool from work surface before turning tool off.
Allow the tool to stop rotating before laying itdown.
CAUTION: Use extra care when working over an edge, as
a sudden sharp movement of grinder may beexperienced.
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 pregnantwomen.
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 iscompleted.
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 difficultybreathing.
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. approvedmask.
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 onthem.
Environmental Safety
1. Paint should be removed in such a manner as to minimize
the amount of dustgenerated.
2. Areas where paint removal is occurring should be sealed
with plastic sheeting of 4milsthickness.
3. Sanding should be done in a manner to reduce tracking of
paint dust outside the workarea.
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 changedfrequently.
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-upprocedures.
During clean up, children and pregnant women should be
kept away from the immediate workarea.
3. All toys, washable furniture and utensils used by children
should be washed thoroughly before being usedagain.
