WARNING: 

Use only impact accessories. Non-impact 

accessories may break and cause a hazardous condition. 
Inspect accessory prior to use to ensure that it con tains 
no cracks.

nOTE: 

The chuck accepts 6.35 mm hex bit tips only. Using 

25 mm bits allows better access in tight spaces.
Place the forward/reverse button 

 4 

 in the locked off (centre) 

position or remove battery pack before changing accessories.

To install an accessory,

 push accessory to fully insert into 

chuck 

 6 

. The chuck collar 

 5 

 does not need to be pulled up to 

lock accessory in place.

To remove an accessory,

 pull the chuck collar away from the 

front of the tool. Remove the accessory and release the collar.

Anvil With Hog Ring (Fig. G)

DCF902

WARNING: 

Use only impact accessories. Non-impact 

accessories may break and cause a hazardous condition. 
Inspect accessory prior to use to ensure that it contains 
no cracks.

CAUTION: 

Inspect anvils, detent pins, and hog rings prior 

to use. Missing or damaged items should be replaced 
before use.

Place the forward/reverse button 

 4 

 in the locked off (centre) 

position or remove battery pack before changing accessories.
To install an accessory on the hog ring anvil, firmly push 
accessory onto the anvil 

 10 

. The hog ring 

 11 

 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.

Usage

Your impact tool generates the following maximum torque:

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.
