Bit

1.  Remove the battery pack from the drill/

driver.

2.  Open the chuck jaws until the opening is 

slightly larger than the bit you intend to 
use, and raise the front of the drill/driver 
slightly to keep the bit from falling out of 
the chuck jaws.

3.  Insert the bit into the chuck.
4.  Rotate the chuck in the direction of the 

arrow marked GRIP to close the chuck 
jaws.

NOTICE: Do not use a wrench to tighten or 
loosen the chuck jaws.

5.  Tighten the chuck jaws securely on the 

bit.

 WARNING:

 Make sure to insert 

the bit straight into the chuck jaws. Do 
not insert the bit into the chuck jaws at an 
angle and then tighten. This could cause 
the bit to be thrown from the drill/driver, 
resulting in possibly serious personal 
injury or damage to the chuck.
