SPECIFIC SAFETY RULES
• Use power tools only with specifi cally desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and fi re.
• When battery pack is not in use, keep it away
from other metal objects like paper clips,
coins, keys, nails, screws, or other small metal
objects that can make a connection from one
terminal to another. Shorting the battery termi-
nals together may cause burns or a fi re.
• Under abusive conditions, liquid may be eject-
ed from the battery; avoid contact. If contact
accidentally occurs, fl ush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
or burns.
SERVICE
• Have your power tool serviced by a qualifi ed
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
• Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring or its own
cord. Cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
• Use clamps or another practical way to secure
and support the workpiece to a stable platform.
Holding the work by hand or against your body
leaves it unstable and may lead to loss of control.
•To reduce the risk of explosion, electric shock
and property damage, always check the work
area for hidden gas pipes, electrical wires or wa-
ter pipes when making blind or plunge cuts.
• Keep hands away from all cutting edges and
moving parts. Do not reach underneath the
workpiece.
• Do not use dull or damaged blade, which can
cause excessive friction, blade binding and kick-
back.
• Know your workpiece. Remove nail and screw
heads before scraping. Hitting hard objects with
blade may cause the tool to kick back.
• 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.

OPERATION
WARNING Always remove battery
pack before changing or removing ac-
cessories. Only use accessories specifi cally
recommended for this tool. Others may be
hazardous.
Fuel Gauge
To determine the amount of charge left in the bat-
tery, 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 fl ash slowly.
To signal the end of charge, 1 light on the fuel gauge
will fl ash quickly for 2-3 seconds and the tool will
not run. Charge the battery pack.
If the tool or battery becomes too hot, the fuel
gauge lights will fl ash in an alternating pattern and
the tool will not run. Allow the tool and battery to
cool down.
To protect against high torque, binding, stalling,
and short circuit situations, the tool will shut down
and all the fuel gauge lights will fl ash. Release the
trigger and restart.
WARNING To reduce the risk of injury,
keep hands away from the blade and all
moving parts. Always wear safety goggles or
glasses with side shields.
WARNING To reduce the risk of explo-
sion, electric shock and property dam-
age, always check the work area for hidden
gas pipes, electrical wires or water pipes
when making blind or plunge cuts.
Typical Applications
A large variety of accessories are available for
applications such as sawing/cutting, scraping,
and sanding.
Sawing/Cutting
Install a sawing/cutting blade at an angle easy to
use. Properly clamp the workpiece. Set the speed
dial to a high speed. Start the tool and allow it to
reach full speed. Use moderate pressure to avoid
burning or scorching the workpiece.
Scraping
Install a scraping blade at an angle easy to use.
Start the tool and allow it to reach full speed. Use
light pressure and a low angle to avoid gouging
and damaging the workpiece.
Sanding
Install a sanding backing pad at an angle easy to
use. Attach a sanding disc, or cut sandpaper to fi t
the backing pad. Generally, use 24 or 36 grit for
heavy stock removal; 50, 60, or 80 grit for medium
stock removal and 120 grit for fi nishing. Always
begin with a coarse grit, using successively fi ner
grits to obtain the desired fi nish.
Properly clamp the workpiece. Start the tool and
allow it to reach full speed. Use light pressure and
long, sweeping, side to side strokes, advancing
forward to produce the desired fi nish.
