Variable Speed Trigger Switch (Fig.A)
To turn the tool on, squeeze the trigger switch
3
. To turn
the tool off, release the trigger switch. Your tool is equipped
with abrake. The chuck will stop when the trigger switch is
fullyreleased.
The variable speed switch enables you to start the application at
aslow speed. The further you squeeze the trigger, the faster the
tool will operate. For maximum tool life, use variable speed only
for starting holes orfasteners.
NOTE: Continuous use in variable speed range is not
recommended. It may damage the switch and should
beavoided.
Forward/Reverse Control Button (Fig.A)
Aforward/reverse control button
4
determines the direction of
the tool and also serves as alock-offbutton.
To select forward rotation, release the trigger switch and depress
the forward/reverse control button on the right side of thetool.
To select reverse, depress the forward/reverse control button on
the left side of the tool. The centre position of the control button
locks the tool in the off position. When changing the position of
the control button, be sure the trigger isreleased.
NOTE: The first time the tool is run after changing the direction
of rotation, you may hear aclick on start up. This is normal and
does not indicate aproblem.
Worklights (Fig.E)
There are three worklights
7
located around the 6.35 mm hex
chuck
6
or anvil
10
. The worklights are activated when the
trigger switch isdepressed.
When the trigger is released, the worklight will stay illuminated
for up to 20 seconds. If the trigger switch remains depressed, the
worklights will remainon.
NOTE: The worklights are for lighting the immediate work
surface and are not intended to be used as aflashlight.
Mode Selector (Fig.A)
Your tool is equipped with amode select button
9
which
allows you to select one of three modes. Select the mode based
on the application and control the speed of the tool using the
variable speed trigger switch

Precision Drive™ (Fig.A)
DCF801
In addition to normal impacting modes, this tool features the
Precision Drive™ mode which enables greater control in lighter
applications to avoid damage to materials or fasteners. It is ideal
for light applications such as cabinet hinge screws or machine
screws. Precision Drive™ mode will work as ascrewdriver in light
applications, before hesitating as the screw head reaches the
work piece, and then (if required) start aslow controlled impact
to ensure the head ends perfectlyflush.
NOTE: This mode is for light duty screwdriving applications.
If the tool will not drive afastener in Precision Drive™
Mode, please select Lo Mode which will give the additional
powerrequired.

Precision Wrench™ (Fig. A)
DCF902
In addition to low speed impacting modes, this tool features
the Precision Wrench™ mode which grants the user greater
control in both fastening and loosening applications. When set
in forward, the tool will fasten until impacting begins. The tool
will then pause for 0.5 seconds before continuing to impact,
providing the user with greater control and reducing the chance
of overtightening or damagingmaterial.
When set in reverse, the tool will impact at anormal speed.
Upon sensing that the fastener has broken free, the tool will
cease to impact and will reduce speed to help prevent “run-off”
of loosehardware.
