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.
Sanding Drywall (Fig. E)

WARNING: To reduce the risk of personal injury, ALWAYS
wear a respirator approved for “Dust andMist” and
connect the drywall sander to a suitable dust extractor.
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.
Proper hand position requires one hand on the main handle
3
and one hand on the main tube
4
.
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.
OPERATION
Instructions for Use

WARNING: Always observe the safety instructions and
applicableregulations.

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories. An accidental
start‑up can causeinjury.
Attaching an AirLock™ Compatible Dust
Extractor (Fig. D, G)
Your drywall sander is compatible with the DeWALT AirLock™
connection system. The AirLock™ allows for a fast, secure
connection between the AirLock™ connector
13
and sander's
dust extraction port
5
.
1. Ensure the collar on the AirLock™ connector is in the unlock
position. (Refer to Fig.D.) Align notches
14
on collar and
AirLock™ connector as shown for unlock and lockpositions.
2. Push the AirLock™ connector onto the adapter
connectorpoint.
3. Rotate the collar to the lockedposition.
NOTE: The ball bearings inside collar lock into slot and
secure the connection.The power tool is now securely
connected to the dustextractor.
NOTE: The sleeve
17
of the dust extraction port can be
Brush‑Type Skirt (Fig. B)
A brush‑type skirt
9
surrounds the abrasive pad on the
DWE7800. This skirt serves two purposes:
• It extends below the surface of the abrasive pad to prevent
the abrasive from “gouging” thework.
• It helps contain the drywall dust until the vacuum cleaner
pulls itaway.
If the skirt is damaged or if it is worn excessively it should be
replaced by a DeWALT authorised servicecentre.
Speed Control Dial (Fig. A)
The DWE7800 sander is equipped with a variable speed control.
Adjust the speed by turning the speed control dial
2
. The speed
control dial is numbered “1” through “5”. The setting “1” is the
slowest speed (approximately 1200RPM) and “5” is the fastest
speed (approximately 2400RPM).
Use the higher speed settings for fast stock removal. Use
the lower speed setting to reduce removal rate for more
precisecontrol.
NOTE: To reduce unexpected tool movement, do not switch
the tool on or off while under load conditions. Allow the grinder
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 the
activation of a ground fault interrupter, throwing of a
circuit breaker, accidental unplugging, or powerfailure.
To start the tool, slide the ON/OFF slider switch
1
toward
the front of the tool. 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.
removed if damaged and replaced by the user. The sleeve is
available as an optional accessory and can be replaced using
ascrewdriver.
