3. 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.

4. 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 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.

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 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.

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. Grinding/cutting rate is

greatest when the tool operates at high speed.

3. Position yourself so that the open-underside of the wheel is

facing away from you.

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 bybending.

5. Remove the tool from the work surface before turning

the tool off. Allow the tool to stop rotating before laying

itdown.

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 metal swarf.

If the power supply is shut off by the RCD, take the tool to an

authorised D

WALT repair agent.



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 electrical shock.

To avoid build-up of metal swarf inside the machine, we

recommend to clear the ventilation slots on a daily basis. Refer

to Maintenance.

Cutting Metal

For cutting with bonded abrasives, always use the

guardtype 1.

When cutting, work with moderate feed, adapted to the

material being cut. Do not exert pressure onto the cutting disc,

tilt or oscillate the machine.

Do not reduce the speed of running down cutting discs by

applying sideward pressure.

The machine must always work in an upgrinding motion.

Otherwise, the danger exists of it being pushed uncontrolled

out of the cut.

When cutting profiles and square bar, it is best to start at the

smallest cross section.

Rough Grinding

Never use a cutting disc for roughing.

Always use the guard type 27.

The best roughing results are achieved when setting the

machine at an angle of 30° to 40°. Move the machine back and

forth with moderate pressure. In this manner, the workpiece

will not become too hot, does not discolour and no grooves

areformed.

Cutting Stone

The machine shall be used only for dry cutting.

For cutting stone, it is best to use a diamond cutting disc.

Operate the machine only with additional dust protection mask.
