OPERATION

WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start‑up can cause injury.
Proper Hand Position (Fig. E)

WARNING: To reduce the risk of serious personal
injury, ALWAYS use proper hand position as shown.

WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
sudden reaction.
Proper hand position requires one hand on the main
handle and one hand on the main tube

Slider Switch (Fig. C)
nOTE: To reduce unexpected tool movement, do not
switch the tool on or off while under load conditions. Allow
the sander to run up to full speed before touching the work
surface. Lift the tool from the surface before turning the tool
off. Allow the tool to stop rotating before putting it down.

WARNING: Before connecting the tool to a power
supply, be sure the slider switch is in the off position
by pressing the rear part of the switch and releasing.
Ensure the slider switch is in the off position as
described above after any interruption in power
supply to the tool, such as dead battery.
To start the tool, slide the ON/OFF slider switch
the front of the tool using the rear portion of the switch. To
stop the tool, release the ON/OFF slider switch.
For continuous operation, slide the switch toward the front
of the tool and press the forward part of the switch inward.
To stop the tool while operating in continuous mode, press
the rear part of the slider switch and release.
Sanding Drywall (Fig. E)

WARNING: To reduce the risk of personal injury,
ALWAYS wear a respirator approved by NIOSH for
"Dust and Mist".
The drywall sander has an articulating sanding head. The
head can swivel in multiple directions, allowing the abrasive
pad to conform to the work surface. This action enables you
to sand the top, middle, and bottom of a wall or ceiling joint
without changing position.
1. Turn the vacuum cleaner switch ON (I).
2. Turn drywall sander switch ON.
3. Position the drywall sander lightly against the work
surface. Apply just enough pressure to align the sanding
head with the work surface.
4. Apply additional pressure to engage the abrasive pad
on the work surface. Move the sander in an overlapping
pattern to smooth the drywall compound down to
a "featheredge".

5. Apply ONLY enough pressure to keep the abrasive pad flat
against the work.
6. Keep the sander in constant motion while the abrasive
pad is in contact with the work surface. Use a steady,
sweeping motion. Excessive pressure, stopping the
sander on the work, or moving the sander erratically can
cause unacceptable swirl marks and unevenness in the
work surface.
nOTE: Do not allow rotating abrasive pad to contact sharp
protrusions. Contact with protruding objects (nails, screws,
electrical boxes, etc.), can severely damage the abrasive pad.
Precautions to Take When Sanding Paint
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.
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:
1. PERsOnAl sAFETY
No children or pregnant women should enter the
‑
work area where the paint sanding is being done
until all clean up is completed.
‑ 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. See your local hardware store for the
proper NIOSH‑approved dust mask.
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.
2. EnViROnMEnTAl sAFETY
Paint should be removed in such a manner as to
‑
minimize the amount of dust generated.
‑ Areas where paint removal is occurring should be
sealed with plastic sheeting of 4 mils thickness.
Sanding should be done in a manner to reduce
‑
tracking of paint dust outside the work area.
3. ClEAning AnD DisPOsAl
‑ 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.
‑ 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.
All toys, washable furniture and utensils used by
‑
children should be washed thoroughly before being
used again.
