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
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.
Speed Control Dial (Fig. A)
The DWE7800 sander is equipped with a variable speed control.
Adjust the speed by turning the speed control dial
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.
Brush-Type Skirt (Fig. B)
A brush-type skirt

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 D
WALT authorised service centre.
