Edge Grinding and Cutting (Fig. K)



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 1/2" (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.

this risk, insert an RCD before use and clean the

ventilation slots daily by blowing dry compressed air

into the ventilation slots inaccordance with the below

maintenanceinstructions.

To perform work on the surface of a workpiece:

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.

Angle

Fig. J

3. Maintain an appropriate angle between the tool

and work surface. Refer to the chart according to

particularfunction.

Function Angle

Grinding 20˚-30˚

Sanding with Flap Disc 5˚-10˚

Sanding with Backing Pad 5˚-15˚

Wire Brushing 5˚-10˚

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.

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 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.
