INSTRUCTIONS
Always wear safety goggles and gloves.
1. If removing wheels from a vehicle, block the wheels and jack the car
as instructed in the owner’s manual.
2. In other applications, be ready for parts shifting when the fastener
is removed.
3. Install the correct impact socket on the tool. Only use impact rated
sockets.
4. Select the correct rotation direction using the button above the
trigger switch.
5. Slide the fully charged battery pack onto the base of the handle. The
tool will operate at peak power with a fully charged battery pack.
6. Place the socket onto the fastener to be removed/tightened.
7. Hold the impact wrench with both hands and squeeze the trigger to
start the tool. The tool is variable speed so the harder you squeeze
the higher the speed.
8. When removing nuts, always squeeze the trigger fully so the tool
operates at its maximum speed to generate maximum torque.
9. If a fastener to be removed is “frozen” and will not loosen after
15 seconds of operation, reverse the impact wrench rotation and
tighten the fastener for 5 seconds to break it loose then change the
rotation direction again to remove the fastener.
10. When tightening fasteners, do not let the tool “rattle” for more than
2-3 seconds. This may overtighten the fastener.
11. Always check tightened fasteners with a torque wrench
recommended by the manufacturer to ensure the correct torque has
been applied. Particularly when tightening wheel nuts.
CHARGE THE BATTERY
NOTE:
A discharged battery pack will be fully charged in approximately
two hours. Remove the battery pack from the tool when not in use.
WARNING
Always charge the battery pack indoors in a well-ventilated area. The
charger must never be subjected to wet conditions.
ELECTRICAL WARNING
POWER SOURCE CONNECTION POWER REQUIREMENTS
This product is designed to operate on a properly grounded
120 volt, 60Hz, single-phase alternating current (AC) power source fused
with a time delayed fuse or circuit breaker. It is recommended that a
qualified electrician verify the ACTUAL VOLTAGE at the receptacle into
which the product will be plugged and confirm that
the receptacle is properly fused and grounded.
DO NOT OPERATE THIS PRODUCT if the ACTUAL power source voltage is
less than 105 volts AC or greater than 132 volts AC. Contact a qualified
electrician if this problem exists. Improper performance
and/or damage to the product will result if operated on inadequate
or excessive power.
CONNECT TO POWER SOURCE
Consult a qualified electrician for proper installation of receptacle at the
power source. This product must be grounded while in use to protect the
operator from electrical shock. If you are not sure if your outlet is properly
grounded, have it checked by a qualified electrician. Do not cut off the
grounding prong or alter the plug in any way and do not use any adapters
between the product’s power cord and the power source receptacle.
Make sure the POWER switch is OFF then connect the power cord to a
properly grounded 120V, 60Hz, single phase, 20 Amp power source.
Do not abuse cord. Never use the cord to carry tools or pull the plug
from an outlet. Keep cord away from heat, sharp edges or moving parts.
Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.
1. Place the charger in a dry location near a 120V/60 Hz
electrical outlet.
2. Plug the charger into the electrical outlet.
3. The green LED light will turn on.
4. Turn the battery pack upside down and slide it onto the charger.
5. The green LED light will turn off and the red LED light will begin to
flash indicating the battery pack is charging.
6. The red LED light will turn off and the green LED light will turn on
when fully charged.
7. Once the battery pack is fully charged, remove the charger plug from
the power source and remove the battery pack from the charger.
NOTE:
Do not charge batteries when the work area or the battery
temperature is at or below 32° F (0° C) or above 113° F (45° C).
