• An extension cord must have adequate wire size (AWG or American Wire Gauge) for
safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is,
16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. When using more than one extension to make up
the total length, be sure each individual extension contains at least the minimum wire size. The
following table shows the correct size to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The lower the gauge number, the heavier the
cord.

• Do not place any object on top of the charger or place the charger on a soft surface
that might block the ventilation slots and result in excessive internal heat. Place the
charger in a position away from any heat source. The charger is ventilated through slots in the
top and the bottom of the housing.
• Do not operate the charger with a damaged cord or plug.
• Do not operate the charger if it has received a sharp blow, been dropped or otherwise
damaged in any way. Take it to an authorized service center.
• Do not disassemble the charger; take it to an authorized service center when service
or repair is required. Incorrect reassembly may result in a risk of electric shock, electrocution or
fire.
• Disconnect the charger from the outlet before attempting any cleaning. This will
reduce the risk of electric shock. Removing the battery pack will not reduce this risk.
• NEVER attempt to connect 2 chargers together.
• The charger is designed to operate on standard 120V household electrical power. Do
not attempt to use it on any other voltage. This does not apply to the vehicular charger.

Charge Indicators
This charger is designed to detect certain problems that can arise. Problems are indicated by the red
light flashing at a fast rate. If this occurs, re-insert the battery pack into the charger. If the problem
persists, try a different battery pack to determine if the charger is working properly. If the new pack
charges correctly, then the original pack is defective and should be returned to a service center or
other collection site for recycling. If the new battery pack elicits the same trouble indication as the
original, have the charger and the battery pack tested at an authorized service center.
HOT/COLD DELAY
This charger has a hot/cold delay feature: when the charger detects a battery that is hot, it
automatically starts a delay, suspending charging until the battery has cooled. After the battery
has cooled, the charger automatically switches to the pack charging mode. This feature ensures
maximum battery life. The red light flashes long, then short while in the hot/cold delay mode.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the charge indicator showing Pack
Charged.
WEAK BATTERY PACKS: Weak batteries will continue to function but should not be expected
to perform as much work.
FAULTY BATTERY PACKS: This charger will not charge a faulty battery pack. The charger will
indicate faulty battery pack by refusing to light or by displaying problem pack or charger.
NOTE: This could also mean a problem with a charger.
Important Charging Notes
1. Longest life and best performance can be obtained if the battery pack is charged when the air
temperature is between 65°F and 75°F (18° – 24°C). DO NOT charge the battery pack in an
air temperature below +40°F (+4.5°C), or above +105°F (+40.5°C). This is important and will
prevent serious damage to the battery pack.
2. The charger and battery pack may become warm to the touch while charging. This is a normal
condition, and does not indicate a problem. To facilitate the cooling of the battery pack after
use, avoid placing the charger or battery pack in a warm environment such as in a metal shed
or an uninsulated trailer.
3. A cold battery pack will charge at about half the rate of a warm battery pack. The battery
pack will charge at that slower rate throughout the entire charging cycle and will not return to
maximum charge rate even if the battery pack warms.
4. If the battery pack does not charge properly:
a. Check operation of receptacle by plugging in a lamp or other appliance;
b. Check to see if receptacle is connected to a light switch which turns power off when you
turn out the lights;
c. Move the charger and battery pack to a location where the surrounding air temperature is
approximately 65°F – 75°F (18° – 24°C);
d. If charging problems persist, take the tool, battery pack and charger to your local service
center.
5. The battery pack should be recharged when it fails to produce sufficient power on jobs which
were easily done previously. DO NOT CONTINUE to use under these conditions. Follow the
charging procedure. You may also charge a partially used pack whenever you desire with no
adverse effect on the battery pack.
6. Foreign materials of a conductive nature such as, but not limited to, grinding dust, metal chips,
steel wool, aluminum foil, or any buildup of metallic particles should be kept away from charger
cavities. Always unplug the charger from the power supply when there is no battery pack in the
cavity. Unplug the charger before attempting to clean.
7. Do not freeze or immerse the charger in water or any other liquid.
WARNING: Shock hazard. Don't allow any liquid to get inside the charger. Electric shock may
result.
WARNING: Burn hazard. Do not submerge the battery pack in any liquid or allow any liquid
to enter the battery pack. Never attempt to open the battery pack for any reason. If the plastic
housing of the battery pack breaks or cracks, return to a service center for recycling.
Storage Recommendations
1. The best storage place is one that is cool and dry, away from direct sunlight and excess heat
or cold.
2. For long storage, it is recommended to store a fully charged battery pack in a cool dry place
out of the charger for optimal results.
NOTE: Battery packs should not be stored completely depleted of charge. The battery pack will
need to be recharged before use.

Usage
Your impact tool can generate the following maximum torque:
CAUTION: Ensure fastener and/or system will withstand the level of torque generated by the
tool. Excessive torque may cause breakage and possible personal injury.
1. Place the socket on the fastener head. Keep the tool pointed straight at the fastener.
2. Press switch to start operation. Release switch to stop operation. Always check torque with a
torque wrench, as the fastening torque is affected by many factors including the following:
• Voltage: Low voltage, due to a nearly discharged battery, will reduce fastening torque.
• Socket size: Failure to use the correct socket size will cause a reduction in fastening torque.
• Bolt size: Larger bolt diameters generally require higher fastening torque. Fastening torque
will also vary according to length, grade, and torque coefficient.
• Bolt: Ensure that all threads are free of rust and other debris to allow proper fastening torque.
• Material: The type of material and surface finish of the material will affect fastening torque.
• Fastening time: Longer fasten ing time results in increased fastening torque. Using a longer
fastening time than recom mended could cause the fasteners to be overstressed, stripped or
damaged.
MAINTENANCE
WARNING: To reduce the risk of serious personal injury, place the forward/reverse
button in the lock-off position or turn tool off and disconnect battery pack before making
any adjustments or removing/installing attachments or accessories.
