FEATURES

KNOW YOUR HAMMER DRILL

See Figure 1.

The safe use of this product requires an understanding of 
the information on the tool and in this operator’s manual as 
well as a knowledge of the project you are attempting. Before 
use  of  this  product,  familiarize  yourself  with  all  operating 
features and safety rules.

AUXILIARY HANDLE ASSEMBLY

Your drill is equipped with an auxiliary handle assembly for 
ease of operation and to prevent loss of control.

BLOWS PER MINUTE

This tool features an impact speed of 0-6,400 BPM in

 LO 

(1) 

speed and 0-24,000 BPM in 

HI (2)

 speed. BPM (Blows 

Per Minute) is the number of impacts per minute.

CHARGER

The charger has a key-hole hanging feature for convenient, 
space-saving storage. Screws should be installed so that 
the center distance is 4-1/8 in. 

DIRECTION OF ROTATION SELECTOR

(FORWARD/REVERSE/CENTER LOCK)

Your drill has a direction of rotation (forward/reverse/center 
lock) selector located above the switch trigger for changing 
the direction of bit rotation. Setting the switch trigger in the 

OFF 

(center  lock)  position  helps  reduce  the  possibility  of 

accidental starting when not in use.

MODE CHANGE RING

Using the mode change ring, the operator can select either 
hammer mode, drive mode, or drilling mode.

KEYLESS CHUCK

The keyless chuck allows you to hand-tighten or release the 
drill bit in the chuck jaws.

TORQUE ADJUSTMENT RING

Your drill has a 24-position clutch. The torque adjustment 
ring can be turned to select the right amount of torque for 
your application.

TWO-SPEED GEAR TRAIN

The two-speed gear train is designed for drilling or driving 
at 

LO (1) 

or 

HI (2)

 speeds. A slide switch is located on top 

of your drill for selecting either 

LO (1) 

or 

HI (2) 

speed.

VARIABLE SPEED

The variable speed switch trigger delivers higher speed with 
increased trigger pressure and lower speed with decreased 
trigger pressure.
