Environmental Safety; Cleaning And Disposal - Berner 061355 Instrucciones De Manejo

NOTE: If the wheel spins after the clamp nut is
tightened, check the orientation of the threaded clamp
nut. If a thin wheel is installed with the pilot on the
clamp nut against the wheel, it will spin because the
height of the pilot prevents the clamp nut from holding
the wheel.
SURFACE GRINDING WITH GRINDING WHEELS
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
rate is greatest when the tool operates at high
speed.
3. Maintain a 20° to 30° angle between the tool and
work surface.
4. Continuously move the tool in a forward and
back motion to avoid creating gouges in the work
surface.
5. Remove the tool from work surface before turning
tool off. Allow the tool to stop rotating before laying
it down.
EDGE GRINDING WITH GRINDING WHEELS
WARNING: Wheels used for cutting and edge
grinding may break or kick back if they bend
or twist while the tool is being used to do cut-
off work or deep grinding. To reduce the risk
of serious injury, limit the use of these wheels
with a standard Type 27 guard to shallow
cutting and notching [less than 13 mm (1/2")
in depth]. The open side of the guard must be
positioned away from the operator.
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
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.
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 serious
personal injury may result.
Precautions To Take When Wire Brushing
Paint
1. Wire brushing of lead based paint is NOT
RECOMMENDED due to the diffi culty of controlling
the contaminated dust. The greatest danger of lead
poisoning is to children and pregnant women.
2. Since it is diffi cult to identify whether or not a paint
contains lead without a chemical analysis, we
recommend the following precautions when wire
brushing any paint:
PERSONAL SAFETY
1. No children or pregnant women should enter the
work area where the paint 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 fi lter should
be replaced daily or whenever the wearer has
diffi culty 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. Wire brushing 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
wire brushing project. Vacuum fi lter 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
