Selecting Drill or Drive Action 
(Cat. No. 2406-20, 2407-20)
1. To use the drilling mode, rotate 

the torque selector collar until the 
drill symbol 

 

 appears in line 

with the arrow. 

2. To use the driving mode rotate 

the  torque selector collar until the 
desired clutch setting appears in 
line with the arrow.

  The adjustable clutch, when prop-

erly adjusted, will slip at a preset torque to 
prevent driving the screw too deep into different 
materials and to prevent damage to the screw 
or tool.

Selecting Hammer, Drill or Drive Action 
(Cat. No. 2408-20)  
1. To use the hammer-drilling 

mode,  rotate the application 
selector collar until the hammer 
symbol 

 appears in line with 

the arrow. Apply pressure to the bit 
to engage the hammering mecha-
nism.

  NOTE:  The number selected on the torque 

selector collar has no effect on operation  of the 
drill in hammer mode. 

When using carbide bits, do not use wa-

ter to settle dust. Do not attempt to drill through 
steel reinforcing rods. This will damage the 
carbide bits.

2. To use the drilling only mode, 

rotate the application selector collar 
until the drill symbol 

 

 appears 

in line with the arrow. 

  NOTE: The number selected on the 

torque selector collar has no effect 
on operation  of the drill in drilling mode.

3. To use the driving screws mode 

rotate the application selector collar 
until the drive symbol 

 appears 

in line with the arrow. Then rotate 
the torque selector collar until the 
desired clutch setting appears in 
line with the arrow.

  The adjustable clutch, when properly adjusted, 

will slip at a preset torque to prevent driving the 
screw too deep into different materials and to 
prevent damage to the screw or tool.

Fuel Gauge
To determine the amount of charge left in the bat-
tery, pull the trigger. The Fuel Gauge will light up 
for 2-3 seconds. 
To signal the end of charge, 1 light on the fuel 
gauge will fl ash for 2-3 seconds.

This driver is intended for use with drill and driver 
bits with a 1/4" hex shank and ball detent recess. 
1. To install the bit, press the bit into the socket 

until the collar snaps back and the bit is locked 
into place.

2. To  remove the bit, pull out the collar, then pull 

out the bit.

NOTE:  It is not necessary to hold the collar out 
when installing and removing bits. The fi rst  time 
the tool is used, it may be necessary to pull out 
the collar. 

Cat. No. 2407-20, 2408-20
This tool is equipped with a spindle lock. The chuck 
can be tightened with one hand, creating higher grip 
strengths on the bit.
1. To open the chuck jaws, turn the sleeve in the 

counterclockwise direction.

  When using drill bits, allow the bit to strike the 

bottom of the chuck. Center the bit in the chuck 
jaws and lift it about 1/16” off of the bottom. 

  When using screwdriver bits, insert the bit far 

enough for the chuck jaws to grip the hex of the 
bit. 

2. To close the chuck jaws, turn the sleeve in the 

clockwise direction. The bit is secure when the 
chuck makes a ratcheting sound and the sleeve 
can not be rotated any further.

3. To remove the bit, turn the sleeve in the coun-

terclockwise direction.

NOTE: A ratcheting sound may be heard when the 
chuck is opened or closed. This noise is part of the 
locking feature, and does not indicate a problem 
with the chuck’s operation.
