WARNING! Read all safety warnings, instructions,
illustrations, and specifications provided with this product.
Failure to follow all instructions listed below may result in electric
shock, fire, and/or serious injury.
Save all warnings and instructions for future reference.
IMPACT DRIVER SAFETY WARNINGS
Wear ear protectors. Exposure to noise can cause hearing loss.
Hold the product by insulated gripping surfaces when
performing an operation where the fastener may contact hidden
wiring. Fasteners contacting a "live" wire may make exposed metal
parts of the product "live" and could give the operator an electric
shock.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
Use protective equipment. Always wear safety glasses when
working with the product. The use of protective clothing is
recommended, such as dust mask, protective gloves, sturdy non-
slip footwear, helmet, and ear defenders.
The dust produced when using the product may be harmful to
health. Do not inhale the dust. Wear a suitable dust protection mask.
Do not use the product on any materials that present a danger to
health (e.g. asbestos).
Turn the product off immediately if the insertion tool stalls. Do not
turn the product on again while the insertion tool is stalled, as doing
so could trigger a sudden recoil with a high reactive force.
Determine why the insertion tool stalled and rectify this, paying heed
to the safety instructions.
The possible causes may be the following:
• The insertion tool is tilted in the workpiece to be machined.
• The insertion tool has pierced through the material to be
machined.
• The product is overloaded.
Do not reach into the product while it is running.
The insertion tool may become hot during use.
WARNING! Danger of burns.
• when changing tools
• when setting the product down
Chips and splinters must not be removed while the product is
running.
When working on walls, ceilings, or fl oors, take care to avoid electric
cables, gas pipes, or water pipes.
Clamp the workpiece with a clamping device. Unclamped
workpieces can cause severe injury and damage.
SPECIFIED CONDITIONS OF USE
The product can be used to tighten and loosen nuts and bolts
whenever no main connection is available.
Do not use the product for any other purpose.
RESIDUAL RISKS
Even when the product is used as prescribed, it is still impossible
to completely eliminate certain residual risk factors. The following
hazards may arise during use and the operator should pay special
attention to avoid the following:
• injury caused by vibration
- Hold the product by designated handles and restrict working
time and exposure.
• hearing injury caused by exposure to noise
- Restrict exposure and wear appropriate hearing protection.
• injuries due to flying debris
- Wear appropriate personal protective equipment, heavy long
trousers, gloves, substantial footwear, and safety glasses, at
all times.
• health hazards caused by breathing toxic dusts
- Wear a mask if necessary.
ATTACHING/REMOVING ACCESSORIES
The product is intended for use with a drill or driver bit.
To attach a drill or driver bit:
1. Pull out the ring.
2. Press the shank of the bit into the hex drive chuck.
To remove the drill or driver bit:
1. Pull out the ring.
2. Remove the drill or driver bit.

OPERATION
NOTE: It is recommended after fastening to always check the
torque with a torque wrench.
The fastening torque is affected by a wide variety of factors including
the following.
• State of battery charge – When the battery is discharged, the
voltage can drop and the fastening torque can be reduced.
• Operation at speeds – Operating the product at low speeds can
cause a reduction in fastening torques.
• Fastening position – Holding the product or the driving fastener in
various angles can affect the torque.
• Drive accessory/socket – Failure to use the correct size accessory
or socket or a non-impact rated accessory may cause a reduction
in the fastening torque.
• The use of accessories and extensions – Depending on the
accessory or extension fitment can reduce the fastening force of
the impact wrench.
• Bolt/Nut – Fastening torques may differ according to the diameter
of the nut or bolt, the class of nut/bolt, and the length of nut/bolt.
• Condition of the fastener – Contaminated, corroded, dry, or
lubricated fasteners may vary the fastening torques.
• Condition and base material – The base material of the fastener
and any component in between the surfaces may effect the
fastening torque (dry or lubricated base, soft or hard base, disc,
seal or washer between fastener and base material).
IMPACTING TECHNIQUES
The longer a bolt, screw, or nut is impacted, the tighter it becomes.
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 preferred torque.
