— INSERTING 

Clean and lightly oil the bit before inserting. Insert the 

dust-free bit into the bit holder with a twisting motion 

until it latches.

The bit locks itself. Check the locking by pulling on 
the tool.

—

 REMOVING  

Retract back the bit holder locking sleeve (3) and pull 

out the bit. 

WARNING

Your new Kress Rotary Hammer 

Drill generates powerful forces to get your 

job done quickly and effectively. These forces may 

cause inferior quality SDS bits to break and jam in 

the chuck

，

We therefore recommend that only high 

quality SDS bits be used with this tool. 

2. AUXILIARY HANDLE (SEE FIG. B)

Slide the handle onto the hammer and rotate to the 

desired working position. To clamp the auxiliary handle 

rotates the handle clockwise. To loosen the auxiliary 

handle, rotate the handle counter-clockwise.

WARNING: Always use the auxiliary 

handle.

3. ADJUSTABLE DEPTH GAUGE (SEE FIG. B)  

Loosen the depth gauge by rotating the handle counter-

clockwise. Slide the depth gauge until the distance 

between the depth gauge end and the drill bit end is equal 

to the depth of hole/screw you wish to make. Then clamp 

the depth gauge by rotating the handle clockwise.

4. ON/OFF SWITCH (SEE FIG. C)

Depress the On/Off switch (5) to start and release it to 
stop your tool.   

— ON/OFF SWITCH WITH VARIABLE SPEED 
CONTROL 

Depress the On/Off switch to start and release it to stop your 

tool. This tool has a variable speed switch (5) that delivers 

higher speeds with increased trigger pressure or delivers 

lower speeds with reduced trigger pressure - speed is 

controlled by varying the pressure applied to the switch. 

5. SWITCH LOCK (SEE FIG. C)

The switch trigger can be locked in the OFF position. 

This helps to reduce the possibility of accidental 

starting when not in use. To lock the switch trigger, 

place the direction of rotation control in the center 

position. 

6. FORWARD AND REVERSE ROTATION 

CONTROL (SEE FIG. C)

Forward rotation: Push the forward and reverse 

rotation control to the left “ 

”, for drilling 

Reverse rotation: Push the forward and reverse 

rotation control to the right “ 

  ”, for removing the 

drill bits.

WARNING: Never change the direction of 

rotation while the tool is rotating, wait 

until it has stopped.  

7. AUXILIARY FUNCTION ON TILE 

1)  Press ON/OFF switch to see the light is on or off. 

Light on indicates the auxiliary function is on, and light 

off indicate the auxiliary function is turn off.  

2)  When operating on the tile, press the auxiliary 

function button on tile (10) first, the green light on 

means that auxiliary function is on, then half-press 

switch, begin pulse auxiliary operation. Until the glaze 

of tile is broken,  press the ON/OFF switch to the 

bottom and begin the drilling .

3) When operating on things rather than tile, keep the 

auxiliary function button closed, to insure the high 

efficiency when drilling.

Note: 

a) 

 Auxiliary function on tile avoids the unexpected 

split of tile. This auxiliary function takes the place of 

previous pre-drilling by glass drill on tile.

b) The auxiliary function on tile is only suitable to 

be used under the hammer drilling position. When 

operating under drilling/chiseling/ Adjust the chuck 

angle mode, make sure to turn the auxiliary function 

off .
