Always remove battery pack before
WARNING
changing or removing accesso-
ries. Only use accessories specifically recom-
mended for this tool. Others may be hazardous.
To reduce the risk of injury, always wear proper
eye protection marked to comply with ANSI Z87.1.
When working in dusty situations, wear appro-
priate respiratory protection or use an OSHA
compliant dust extraction solution.
Fuel Gauge
To determine the amount of charge left in the battery,
turn the tool ON. The Fuel Gauge will light up for 2-3
seconds. When less than 10% of charge is left, 1 light
on the fuel gauge will flash 4 times.
To signal the end of charge, 1 light on the fuel gauge
will flash 8 times and the tool will not run. Charge
the battery pack.
If the battery becomes too hot, the fuel gauge lights
will flash and the tool will not run. Allow the battery
to cool down.
Installing/Removing Bits
Always remove the battery before inserting or remov-
ing bits. Select the proper style and size bit for the job.
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 collar 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 collar in the counter-
clockwise 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.
Selecting Drill or Drive Action
(Cat. No. 3403-20)
1. To use the drilling mode, rotate
the torque selector collar until the
drill symbol
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 proper
-ly 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. 3404-20)
1. To use the hammer-drilling
mode, rotate the torque selector
collar until the hammer symbol
appears in line with the arrow. Ap-
ply pressure to the bit to engage
the hammering mechanism.
NOTE: When using carbide bits,
do not use water 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 torque selector collar
until the drill symbol
in line with the arrow.
3. To use the driving screws mode,
rotate 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.
The torque specifications shown here are approximate
values obtained with a fully charged battery pack.
