IMPORTANT SAFETY RULES
When using power tools, always prevent exposure and breathing of harmful
dust and particles.
WARNING: Some dust created by power sanding, sawing, grinding, drilling and
other construction activities contains chemicals known to the State of California to
cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• Lead from lead-based paints.
• 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 dust masks that are specially
designed to filter out microscopic particles.
WARNING: Handling the power cord on corded products may expose you to lead, a
chemical known to the State of California to cause cancer and birth defects or other
reproductive harm. Wash hands after handling.
WORK AREA
Keep work area clean and well lit. Cluttered and dark areas invite accidents.

MEMORY FUNCTIONS:
Certain work environments requires a constant working torque range. The memory
function will hold the selected torque setting until it has been adjusted.
VARIABLE SPEED SWITCH
The variable speed switch provides safety feature to the user for screw driving.
To turn the tool on, squeeze the trigger switch. To turn the tool off, release the trigger
switch (see Fig. 1A).
Your tool is equipped with a brake. The chuck will stop as soon as the trigger switch is
fully released. The variable speed switch enables you to select the best speed for a
particular application. The farther you squeeze the trigger, the faster the tool will
operate.
Use lower speeds for starting holes without a center punch, drilling metals or plastic,
driving screws and drilling ceramics, or in any application requiring high torque.
Higher speeds are better drilling in wood, wood compositions and for using abrasive
and polishing accessories. For maximum tool life, use variable speed only for starting
holes or fasteners.
NOTE: Continuous use in variable speed range is not recommended. It may damage
the switch and should be avoided.
FORWARD / REVERSE CONTROL BUTTON
A forward/reverse control button determines the direction of the tool and also serves as
a lock off button. To select forward rotation, RELEASE THE VARIABLE SPEED
SWITCH (see Fig. 1A), and depress the forward/reverse control button (see Fig. 1B),
toward left side of the tool. To select reverse, depress the forward/reverse control
button, toward right side of the tool. The center position of the control button locks the
tool in the off position. When change the position of the control button, making sure
the trigger is released.
NOTE: The first time the tool is run after changing the direction of rotation, you may
hear a click on start up. This is normal and does not indicate a problem.

-12
BUILT-IN LED LIGHT
A built-in LED light can illuminate the work area and improve vision when
drilling/driving in areas with insufficient light.
ELECTRIC BRAKE
The variable speed switch is equipped with a circuit design electric of brake function.
The tool will consistently operate to quickly stop rotating after the switch release.
BATTERY POWER INDICATOR
Trigger the tool and Battery Indicator to show the battery pack’s remaining capacity
1. One light ON: 30% remaining capacity.
2. Two lights ON: 60% remaining capacity.
3. All lights ON: 100% remaining capacity.
Always check the direction of the rotation before use.
Due to the auto shut-off function, if tool is repeatedly operated on and off
in a short time frame, the MCU will determine it as being over current resulting in
tool shut down. This phenomenon occurs most frequently in the first torque stage.
1. After continuous use, allow the impact wrench to sit idle for 15 minutes before
replacing the battery. The temperature of the motor, switch, etc., will rise if the
work is started again immediately after the battery has been changed, eventually
resulting in burned-out.
2. Place the point of the bolt in the socket. Keep the tool pointed straight at the bolt.
3. Apply forward pressure to the tool to prevent the socket from slipping off the bolt.
4. To start, turn impact wrench/driver on. Always check torque with a torque wrench.
The fastening torque can be affected by many factors including the following:
Voltage: Low voltage due to a nearly discharged battery will reduce the fastening
torque.
Socket Size: Failure to use the correct socket size will cause a reduction in fastening
torque.
Variable Speed Trigger Switch: Operating the tool at a reduced speed will reduce the
fastening torque.
NOTE
NOTE

-13
Bolt Size: Larger bolt diameters generally require higher fastening torque. Fastening
torque will also vary according to length, grade, and torque coefficient.
Material: The type of material and surface finish of the material will affect fastening
torque.
Fastening Time: Longer fastening time results in increased fastening torque. Using a
longer fastening time than recommended could cause the screws to be overstressed,
stripped or damaged.
Continuous use in variable speed range is not recommended. It may
damage the switch and should be avoided.
When change the position of the control button, making sure the variable
speed switch is released.
The first time the tool is run after changing the direction of rotation, you
may hear a click on start up. This is normal and does not indicate a problem.
MAINTENANCE
Remove the battery pack from this tool before cleaning solutions.
This tool is lubricated before it leaves the factory. This lubrication should
last for the life of the tool. No further lubrication is required.
CLEANING
