SAFETY INSTRUCTIONS
WARNING: Read all safety
warnings and instructions!
Failure to follow the warnings and
instructions may result in electric shock,
re and/or serious personal injury. Save
all warnings and instructions for future
reference.
The “term power tool” in the warnings refers
to your mains-operated (corded) power or
battery-operated (cordless) power tool.
WARNING: Risk of re and
electric shock. Dry location use only. Do
not expose to rain. Risk of injury.
WORK AREA SAFETY
1. Keep the work area clean and well lit.
Cluttered or dark areas invite accidents.
2. Do not operate power tools in explosive
atmospheres, such as in the presence of
ammable liquids, gases or dust. Power
tools create sparks that 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
1. 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.
2. Do not expose power tools to rain or
wet conditions. Water entering a power tool
will increase the risk of electric shock.
BATTERY TOOL USE
AND CARE
1. Recharge only with the charger
specied by the manufacturer. A charger
that is suitable for one type of battery pack
may create a risk of re when used with
another battery pack.
2. Use power tools only with specically
designated battery packs. Use of any
other battery packs may create a risk of
injury and re.
3. When the battery pack is not in use,
keep it away from other metal objects,
such as 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 re.
4. Under abusive conditions, liquid may
be ejected from the battery; avoid contact.
If contact accidentally occurs, ush with
water. If liquid contacts eyes, also seek
medical help. Liquid ejected from the battery
may cause irritation or burns.
SERVICE
1. Have your power tool serviced by a
qualied repair person, using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
SPECIFIC SAFETY RULES FOR
BATTERY PACK
1. Use battery only with chargers listed.
Battery pack Charger
252-8016
252-8017
252-8020
Charge before rst use.

2. Know your power tool. Read the
Instruction Manual carefully. Learn the
tool’s applications and limitations, as well
as the specic potential hazards related to
this tool. Following this rule will reduce the
risk of electric shock, re, and serious injury.
3. Do not place the battery near re or
heat. This will reduce the risk of explosion
and possible injury.
4. Do not crush, drop or damage the
battery pack. Do not use a battery pack or
charger that has been dropped or received
a sharp blow. A damaged battery is subject
to explosion. Properly dispose of a dropped
or damaged battery immediately.
5. Batteries vent hydrogen gas and can
explode in the presence of a source of
ignition, such as a pilot light. To reduce
the risk of serious personal injury, never use
any cordless product in the presence of an
open ame. An exploded battery can propel
debris and chemicals. If exposed, ush the
exposed area with water immediately.
6. Do not charge the battery in a damp or
wet location. Following this rule will reduce
the risk of electric shock.
7. For best results, your battery should be
charged in a location where the temperature
is more 41°F (5°C) but less that 122°F (50°C).
Do not store outside or in vehicles.
8. Under extreme usage or temperature
conditions, battery leakage may occur.
If liquid comes in contract with your skin,
wash immediately with soap and water,
then neutralize with lemon juice or vinegar.
If liquid gets in your eyes, ush them with
clean water for at least 10minutes, and
then seek immediate medical attention.
Following this rule will reduce the risk of
serious personal injury.
9. Do not let gasoline, oils, petroleum-
based products, etc. come in contract with
plastic parts. They contain chemicals that
can damage, weaken or destroy plastic.
10. Have your battery pack serviced by a
qualied repair person using only identical
replacement parts. This will ensure that the
safety of the battery pack is maintained.
11. Save these instructions. Refer to them
frequently and use them to instruct others who
may use this tool. If you lend someone this
tool, lend these instructions also to prevent
misuse of the product and possible injury.

OPERATION
POWER INDICATOR (FIG. 1)
This Lithium-Ion battery pack is equipped
with a power indicator that displays the
battery pack’s charge status. Press the power
indicator button to display the LED lights.
The LED lights will stay lit for approximately
5 seconds.
The LED indicator will shine green to indicate
50%-100% charge. The LED indicator will shine
orange to indicate 10%-50% charge. The LED
indicator will shine red when the battery pack’s
charge is less than 10% capacity.
LED WORKLIGHTS (FIG.1)
This battery pack is equipped with two LED
worklights to provide additional light on the
surface of the workpiece for operation in
lower light situations.
To turn on the LED worklights , quickly press
the power indicator button two times . Quickly
press the power indicator button two times
again, and the LED worklights will turn off.
BATTERY PROTECTION
Integrated protective circuitry prevents the
battery pack from extreme temperatures,
over discharge, and over-charge. To protect
the battery from damage and prolong its life,
the battery pack circuitry will turn off the
battery pack if it becomes overloaded or if
the temperature becomes too high during
use. This may happen in extremely high
torque, binding, and stalling situations. The
battery pack will begin normal operation
when it cools down.
COLD WEATHER OPERATION
When the battery pack is very cold, it may
“pulse” for the rst minute of use to warm
itself. Put the battery pack on a tool and use
the tool in a light application. After about a
minute, the battery pack will have warmed
itself and will operate normally.
WHEN TO CHARGE THE
BATTERY PACK
NOTICE: This Lithium-Ion battery pack
is shipped partially charged. Before using it
the rst time, fully charge the battery pack.
It is not necessary to run down the battery
pack charge before recharging. The Lithium-
Ion battery can be charged at any time and
will not develop a “memory” when charged
after only a partial discharge.
Remove the battery pack from the tool when
convenient for you and your job. “Top off” the
battery pack charge by charging it for a time
before starting a big job or long period of use.
1. Use the power indicator to determine
when you need to recharge the
battery pack.
2. You can “top-off” your battery pack’s
charge before starting a big job or long
period of use.

3. Due to Lithium-Ion’s fade-free
properties, the only time it is necessary
to charge the Lithium- Ion battery pack
is when the pack has reached the end of
its charge. To signal the end of charge,
power to the tool will drop quickly.
Charge the battery pack as needed.
HOW TO CHARGE THE BATTERY
PACK (FIG.2)
A fully discharged battery pack will charge
in about 30 minutes in a surrounding
temperature between 50°F (10°C) and 104°F
(40°C).
1. Charge the Lithium-Ion battery pack
with the correct charger.
2. Connect the charger to a power supply.
3. Align the raised ribs of the battery pack
with the slot in the charger.
4. Insert the battery pack into the charger.
5. The charger will communicate with the
battery pack to evaluate the condition of
the battery pack.
6. The green lights will ash while the
battery pack is charging. After charging
is complete, the green LED on the
charger will be on. The ickering red
light indicates a defective battery or a
bad connection between the battery
and the charger.
7. The battery pack will fully charge, but
will not overcharge, if left on the charger.

attempt to replace the batteries. Handling
the batteries, especially when wearing rings
and jewelry, could result in a serious burn.
To obtain the longest possible battery life,
read and understand the operator’s manual.
It is good practice to unplug the Charger and
remove the Lithium-Ion battery pack when
it is not in use. For Lithium-Ion battery pack
storage longer than 30 days:
1. Store the Lithium-Ion battery pack
where the temperature is below 80°F
(26°C) and free of moisture.
2. Store Lithium-Ion battery packs in a
30%-50% charged condition.
3. Every six months of storage, fully charge
the Lithium-Ion battery pack.
4. Exterior may be cleaned with a cloth or
soft non-metallic brush.
