ASSEMBLY

WARNING

To reduce the risk of injury, always 

unplug  tool  before  changing  or 

removing accessories. Only use accessories 

specifically recommended for this tool. Others 

may be hazardous.

To reduce the risk of injury, always use a side 

handle  when  using  this  tool. Always  brace  or 

hold securely.

Adjusting the Side Handle Position

1.  Loosen the side handle by unscrewing the side 

handle grip until the side handle rotates freely. 

2.  Rotate the side handle to the desired position. 

3.  Tighten the side handle grip securely.

Setting the Depth Gauge

1.  Press in the clamping lever.

2.  Slide the depth gauge rod backward or forward 

until it is set for the desired depth. 

 

NOTE:

 The drilling depth is the distance between 

the tip of the bit and the tip of the rod.

3.  Release the clamping lever.

WARNING

To reduce the risk of injury, do not 

grasp  the  bit  while  the  chuck  is 

rotating or while the bit is falling from the chuck.

Installing Drill Bits and Chisels

Only use accessories with SDS or SDS Plus shanks.

Be sure that the shank of the bit is clean. Dirt particles 

may cause the bit to line up improperly. Do not use 

bits larger than the maximum recommended capacity 

of the drill because gear damage or motor overload-

ing may result. For best performance, be sure that 

the bit is properly sharpened and the shank is lightly 

greased before use.

1. Insert the bit or chisel into the nose of the tool. 

2. Rotate  bit  slowly  until  it  aligns  with  the  locking 

mechanism.                         

3. Push bit into tool until it locks.  

4. Check that the bit is locked 

properly; it should be pos-

sible to pull the bit back and 

forth slightly (about 1/4").

5. To remove bits and chisels, 

pull bit holder release collar 

toward the rear of tool and 

remove bit. 

 

NOTE:

 Use caution when 

handling hot bits and chisels.
