contacting a “live” wire may make exposed metal 

parts of the power tool “live” and could give the 

operator an electric shock.

• Maintain labels and nameplates. These carry 

important information. If unreadable or missing, 

contact a MILWAUKEE service facility for a free 

replacement.

• WARNING: Some dust created by power sanding, 

sawing, grinding, drilling, and other construction 

activities contains chemicals known to cause 

cancer, birth defects or other reproductive harm. 

Some examples of these chemicals are:

 • lead from lead-based paint

  • crystalline silica from bricks and cement and other 

   masonry products, and

 • arsenic and chromium from chemically-treated

   lumber.

  Your risk from these exposures varies, depending 

on how often you do this type of work. To reduce 

your exposure to these chemicals: work in a well 

ventilated area, and work with approved safety 

equipment, such as those dust masks that are spe-

cially designed to fi lter out microscopic particles.

Shorting the battery termi-

nals together may cause burns or a fi re.

Liquid ejected from the battery may cause irritation 

or burns.

This will ensure that the safety of the power 

tool is maintained.

Slot

Tab

Line

Lock

Line up the tabs on the battery with the slots in the 

tool opening. Slide the battery all the way into the 

tool. Turn the battery clockwise to lock it in place. 

The line on the battery will line up with the

on 

the tool. The tool will not run if the battery is not 

properly locked into the tool.

Turn the battery cap counterclockwise to unlock. 

Pull the battery out of the tool.

To determine the amount of charge left in the bat-

tery, press the forward/reverse switch. The Fuel 

Gauge will light up for 2-3 seconds. 

Always remove the battery before inserting or 

removing bits. Select the proper style and size bit 

for the type of screw you are using.

1. To install the bit, pull out the collar. 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.

It is not necessary to hold the collar out 

when installing and removing bits. 

The handle is designed for convenience and con-

trol. The durable, center pivot allows the handle to 

be used in the conventional shape or folded into a 

pistol grip. Access to the forward/reverse switch and 

lock switch is comfortable in either handle position.

This tool has an adjustable clutch 

for driving different types of screws 

into different materials. When prop-

erly adjusted, the clutch will slip at 

a preset torque to prevent driving 

the screw too deep and to prevent 

damage to the screw or tool. 

To adjust the clutch, turn the clutch 

adjusting ring so that the desired 

setting (1-21) lines up with the arrow 

on the motor housing, as shown.

The torque specifications shown here are ap-

proximate values obtained with a fully charged 

battery pack.

When the battery is installed, the tool is in operat-

ing condition. The lock switch prevents accidental 

starting by locking the forward/reverse switch. Al-

ways set the lock switch to “lock” before performing 

maintenance, changing accessories, 

storing the tool and any time the tool 

is not in use.

1. To lock, push the lock switch to 

display the lock

symbol.

2. To unlock, push the lock switch to 

display the unlock

 

symbol.

1. For low speed and more torque, 

push the speed selector back ("1" 

is displayed).

2. For high speed and less torque, 

push the speed selector forward 

("2" is displayed).

Press and hold the top of the switch ◄  for forward 

rotation, and the bottom of the switch ► for reverse 

rotation. The switch will automatically return to the 

center OFF position when it is released.

To prevent extra driving force after the selected 

torque has been reached, the tool will automatically 

shut off if the clutch slips. At higher clutch settings, 

this feature may not immediately engage. Release 

the switch to reset the automatic shut-off. 

Cold Weather Operation
MILWAUKEE

 Lithium-Ion battery packs are de-

signed to operate in temperatures below freezing. 

When the battery pack is too cold, it may need to 

warm up before normal use. Put the battery on a 

tool and use the tool in a light application. It may 

“buzz” for a short time until it warms up. When the 

buzzing stops, use the tool normally.

*  When set to high speed, set the clutch at 10 or below. 

The Automatic Shut-Off may not work at higher clutch 

settings (see "Automatic Shut-Off").

 Because the settings shown in the table are 

only a guide, use a piece of scrap material to test 

the different clutch settings before driving screws 

into the workpiece.
