GENERAL SAFETY RULES-FOR ALL BATTERY OPERATED TOOLS

WARNING

Failure to follow all instructions listed below may result in electric shock, fi re and/or
serious injury. The term "power tool" in all of the warnings listed below refers to your
mains-operated (corded) power tool or battery-operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

READ ALL INSTRUCTIONS

WORK AREA SAFETY

1. Keep work area clean and well lit.
Cluttered or dark areas invite acci­dents.

2. Do not operate power tools in ex-

plosive atmospheres, such as in the
presence of fl ammable liquids, gases,
or dust. Power tools create sparks which

may ignite the dust or fumes.

3. Keep children and bystanders away
while operating a power tool. Distrac­tions can cause you to lose control.

ELECTRICAL SAFETY

4. Power tool plugs must match the
outlet. Never modify the plug in any
way. Do not use any adapter plugs
with earthed (grounded) power tools.

Unmodifi ed plugs and matching outlets
will reduce risk of electric shock.

5. Avoid body contact with earthed or

grounded surfaces such as pipes,
radiators, ranges and refrigerators.

There is an increased risk of electric shock
if your body is earthed or grounded.

6. Do not expose power tools to rain or
wet conditions. Water entering a power
tool will increase the risk of electric
shock.

7. Do not abuse the cord. Never use the

cord for carrying, pulling, or unplug­ging the power tool. Keep cord away
from heat, oil, sharp edges, or mov­ing parts. Damaged or entangled cords

increase the risk of electric shock.

8. When operating a power tool out-

doors, use an extension cord suitable
for outdoor use. Use of a cord suitable

for outdoor use reduces the risk of elec­tric shock.

PERSONAL SAFETY

9. Stay alert, watch what you are do-

ing and use common sense when
operating a power tool. Do not use
a power tool while you are tired or
under the infl uence of drugs, alcohol
or medication. A moment of inattention

while operating power tools may result
in serious personal injury.

10. Use safety equipment. Always wear
eye protection. Safety equipment such
as dust mask, non-skid safety shoes,
hard hat, or hearing protection used
for appropriate conditions will reduce
personal injuries.

11. Avoid accidental starting. Ensure the

switch is in the off-position before plug­ging in. Carrying tools with your fi nger on

the switch or plugging in power tools that
have the switch on invites accidents.

12. Remove any adjusting key or wrench
before turning the power tool on. A
wrench or a key left attached to a rotat­ing part of the power tool may result in
personal injury.

13. Do not overreach. Keep proper foot-
ing and balance at all times. This
enables better control of the power tool
in unexpected situations.

14. Dress properly. Do not wear loose

clothing or jewellery. Keep your hair,
clothing and gloves away from moving
parts. Loose clothes, jewellery, or long

hair can be caught in moving parts.

15. If devices are provided for the connec-

tion of dust extraction and collection
facilities, ensure these are connected
and properly used. Use of these de-

vices can reduce dust-related hazards.

POWER TOOL USE AND CARE

16. Do not force the power tool. Use the

correct power tool for your applica­tion. The correct power tool will do the

job better and safer at the rate for which
it was designed.

17. Do not use the power tool if the switch
does not turn it on and off. Any power tool
that cannot be controlled with the switch is
dangerous and must be repaired.

18. Disconnect the plug from the power

source and/or the battery pack from
the power tool before making any
adjustments, changing accessories,
or storing power tools. Such preven-

tive safety measures reduce the risk of
starting the tool accidentally.

19. Store idle power tools out of the reach

of children and do not allow persons
unfamiliar with the power tools or
these instructions to operate power
tools. Power tools are dangerous in the

hands of untrained users.

20. Maintain power tools. Check for

misalignment or binding of moving
parts, breakage of parts and any
other condition that may affect the
power tool's operation. If damaged,
have the power tool repaired before
use. Many accidents are caused by

poorly maintained power tools.

21. Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to
bind and are easier to control.

22. Use the power tool, accessories and

tool bits etc., in accordance with
these instructions and in the manner
intended for the particular type of
power tool, taking into account the
working conditions and the work to
be performed. Use of the power tool for

operations different from those intended
could result in a hazardous situation.

BA TTER Y T OOL USE AND CARE

23. Ensure the switch is in the off posi­tion before inserting battery pack.

Inserting the battery pack into power
tools that have the switch on invites
accidents.

24. Recharge only with the charger speci-
fi ed by the manufacturer. A charger
that is suitable for one type of battery
pack may create a risk of fi re when used
with another battery pack.

25. Use power tools only with specifi cally
designated battery packs. Use of any
other battery packs may create a risk of
injury and fi re.

26. 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 terminals

together may cause burns or a fi re.

27. Under abusive conditions, liquid may

be ejected from the battery, avoid
contact. If contact accidentally oc­curs, fl ush with water. If liquid con-
tacts eyes, additionally seek medical
help. Liquid ejected from the battery

may cause irritation or burns.

SERVICE

28. 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.

SPECIFIC SAFETY RULES

1. Maintain labels and nameplates.
These carry important information.
If unreadable or missing, contact a
MILWAUKEE service facility for a free
replacement.

2. 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 chemically­treated 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 specially designed to
fi lter out microscopic particles.

3. Wear ear protectors with impact
drills. Exposure to noise can cause

hearing loss.

4. Hold power tools by insulated grip-

ping surfaces when performing an
operation where the cutting tool may
contact hidden wiring or its own cord.

Contact with a “live” wire will make ex­posed metal parts of the tool “live” and
shock the operator.

Forward

Reverse

1. For forward (clockwise) rotation, push
the forward/reverse switch in the direc­tion shown. Check the direction of rota­tion before use.

2. For reverse (counterclockwise) rotation,
push the forward/reverse switch in the
direction shown. Check the direction of
rotation before use.

3. To lock the trigger, push the forward/re­verse switch to the center position. The
trigger will not work when the forward/
reverse switch is in the locked position.
Always lock the trigger or remove the
battery pack before performing mainte­nance, changing accessories, storing
the tool and any time the tool is not in
use.

Starting, Stopping and Controlling
Speed

These tools may be operated at any speed
from 0 to full speed.

1. To start the tool, pull the trigger.

2. To vary the driving speed, simply in­crease or decrease pressure on the
trigger. The further the trigger is pulled,
the greater the speed.

3. To stop the tool, release the trigger
and the electric brake stops the tool
instantly.

Impacting Techniques

The longer a bolt, screw, or nut is impacted,
the tighter it will become. To help prevent
damaging the fasteners or workpieces,
avoid excessive impacting. Be particularly
careful when impacting smaller fasteners
because they require less impacting to reach
optimum torque.

Practice with various fasteners, noting the
length of time required to reach the desired
torque. Check the tightness with a hand­torque wrench. If the fasteners are too tight,
reduce the impacting time. If they are not
tight enough, increase the impacting time.

Impacting for two seconds is generally
suffi cient for a 3/8" bolt and one second
for a 5/16" bolt. However, oil, dirt, rust or
other matter on the threads or under the
head of the fastener affects the degree of
tightness.

The torque required to loosen a fastener
averages 75% to 80% of the tightening
torque, depending on the condition of the
contacting surfaces.

On light gasket jobs, run each fastener down
to a relatively light torque and use a hand
torque wrench for fi nal tightening.

WARNING

To reduce the risk of injury,
always unplug the charger and
remove the battery pack from
the charger or tool before
performing any maintenance.
Never disassemble the tool,
battery pack or charger. Contact a
MILWAUKEE service facility for ALL
repairs.

Keep your tool, battery pack and char­ger in good repair by adopting a regular
maintenance program. After six months
to one year, depending on use, return the
tool, battery pack and charger to a
MILWAUKEE service facility for:

• Lubrication

• Mechanical inspection and cleaning
(gears, spindles, bearings, housing,
etc.)

• Electrical inspection (battery pack,
charger, motor)

• T esting to assure proper mechanical and
electrical operation

Maintaining Tool

If the tool does not start or operate at full pow­er with a fully charged battery pack, clean
the contacts on the battery pack. If the tool
still does not work properly, return the tool,
charger and battery pack, to a MILWAUKEE
service facility for repairs.

WARNING

To reduce the risk of personal injury
and damage, never immerse your
tool, battery pack or charger in liquid
or allow a liquid to fl ow inside them.

Cleaning

Clean dust and debris from charger and tool
vents. Keep tool handles clean, dry and free
of oil or grease. Use only mild soap and a
damp cloth to clean the tool, battery pack
and charger since certain cleaning agents
and solvents are harmful to plastics and other
insulated parts. Some of these include gaso­line, turpentine, lacquer thinner, paint thinner ,
chlorinated cleaning solvents, ammonia and
household detergents containing ammonia.
Never use fl ammable or combustible sol-
vents around tools.
