ENGLISH
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.
Worklight (Fig. A)
There is a worklight
7
located on the foot of the tool. The
worklight will be 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 worklight is for lighting the immediate work surface
and are not intended to be used as aflashlight.
Speed Selector (Fig. A)
Your tool is equipped with a speed selector
8
which allows you
to select one of three speeds. Select the speed based on the
application and control the speed of the tool using the variable
speed trigger switch

WARNING: Use only impact accessories. Non-impact
accessories may break and cause a hazardous condition.
Inspect accessories prior to use to ensure that it con tains
nocracks.

CAUTION: Inspect anvils, detent pins and hog rings prior
to use. Missing or damaged items should be replaced
beforeuse.
Place the switch in the locked off (centre) position or remove
battery pack before changingaccessories.
Anvil with Hog Ring (Fig. C)
DCF897
To install an accessory on the hog ring anvil, firmly push
accessory onto the anvil
3
. The hog ring
12
compresses to
allow the accessory to slide on. After accessory is installed, the
hog ring applies pressure to help provide accessoryretention.
To remove an accessory, grasp the accessory and firmly pull
itoff.
NOTE: The thru-hole (Fig.C) allows an O-ring with retaining pin
or a 1-piece retaining pin to be used to help secure sockets and
accessories to thetool.
Anvil with Quick-Release Chuck (Fig. D)
DCF898
NOTE: The chuck accepts 11 mm hex accessoriesonly.
To install an accessory, pull the chuck collar
13
away from
the front of the tool, insert the accessory and release the collar.
The accessory is locked inplace.
To remove an accessory, pull the chuck collar away from the
front of the tool. Remove the accessory and release thecollar.

Usage
Your impact tool generates the following maximum torque:
Cat # Nm
Speed 3/2/1
Ft.-Lbs.
Speed 3/2/1
In.-Lbs
Speed 3/2/1
DCF897 950/400/130 700/300/100 8400/3540/1150
DCF898 680/400/130 500/300/100 8400/3540/1150

CAUTION: Ensure fastener and/or system will withstand
the level of torque generated by the tool. Excessive torque
may cause breakage and possible personalinjury.
1. Place the accessory on the fastener head. Keep the tool
pointed straight at thefastener.
2. Press switch to start operation. Release the switch to stop
operation. Always check torque with a torque wrench, as
the fastening torque is affected by many factors including
the following:
• Voltage: Low voltage, due to a nearly discharged
battery, will reduce fasteningtorque.
• Accessory size: Failure to use the correct accessory
size will cause a reduction in fasteningtorque.
• Bolt Size: Larger bolt diameters generally
require higher fastening torque. Fastening torque
will also vary according to length, grade, and
torquecoefficient.
• Bolt: Ensure that all threads are free of rust and other
debris to allow proper fasteningtorque.
• Material: The type of material and surface finish of
the material will affect fasteningtorque.
• Fastening Time: Longer fasten ing time results in
increased fastening torque. Using a longer fastening
time than recom mended could cause the fasteners to
be overstressed, stripped ordamaged.
