This hand-held cordless impact wrench is intended to tighten and loosen mechanical
xings (nuts, bolts, etc). It is intended for domestic and light commercial use only. Any
other application is considered misuse.
General Safety Instructions For Power Tool Use
Read all safety warnings and all instructions. Failure to follow the warning and
instructions may result in electric shock, re and/or serious injury.
Most important: You must know how to safely start and stop this machine, especially
in an emergency.
Keep the work area tidy and clean. Attempting to clear clutter from around the
machine during use will reduce your concentration. Mess on the oor creates a trip
hazard. Any liquid spilled on the oor could result in your slipping.
Find a suitable location. If the machine is bench mounted, the location should
provide good natural light or articial lighting as a replacement. Avoid damp and
dust locations as it will have a negative e󰀨ect on the machine's performance. If the
machine is portable do not expose the tool to rain. Do not operate power tools near
any ammable materials.
Keep bystanders away. Children, onlookers and passers-by must be restricted from
entering the work area for their own protection. The barrier must extend a suitable
distance from the tool user. Unplug and store all power tools that are not in use. A
power tool should never be left unnoticed while connected to the power supply. They
must be stored in a suitable location, locked up and kept from children.
Do not overload or misuse the tool. All tools are designed for a purpose and are
limited to what they are capable of doing. Do not attempt to use a power tool (or
adapt it in any way) for an application it is not designed for. Select a tool appropriate
for the size of the job. Overloading a tool will result in tool failure and user injury: This
includes the use of accessories.
Dress properly. Loose clothing, long hair and jewelry are all dangerous because they
can become entangled in moving machinery: This can also result in parts of body
being pulled into the machine. Clothing should be close-tted, with long hair tired back
and jewelry and neckties removed. Footwear must be fully enclosed and have a non-

SAFETY INSTRUCTIONS
slip sole.
Wear personal protective equipment (PPE). Dust, noise, vibration and swarf can be
dangerous if not fully emphasized. If the work involving the power tool creates dust or
fumes wear a dust mask. Vibration to the hand, caused by operating some tools for
long time use must be protected against. Wear vibration-reducing gloves and allow
long breaks between uses. Protect against dust and swarf by wearing approved safety
goggles or a face shield. These are some common hazards and preventions, however,
always nd out what hazards are involved within the machine/ work process and wear
the most suitable protective equipment.
Do not breathe contaminated air. If the work creates dust or fumes from the
machine (if possible) turn to an extraction system either locally or remotely. Working
outdoors can also help.
Move the machine as instructed. If the machine is handheld, do not carry it by the
power supply cable. If the product is heavy, ask a second or third person to help move
it safely or use a mechanical device. Always refer to the instructions for the correct
method.
Do not overreach. Operate the machine too far from you can result in a loss of
balance and your falling. This will result in injury.
Maintain your tools correctly. A well-maintained tool will do the job safely. Replace
any damaged or missing parts immediately with original parts from the manufacturer.
Keep blades sharp, moving parts clean, oiled or greased, handles clean and
emergency devices working.
Wait for the machine to stop. Unless the machine is equipped with a safety brake,
some parts may continue to move due to momentum. Wait for all parts to stop,
then unplug it from the power supply before making any adjustments, Carry out
maintenance operations or just nishing using the tool.
Remove and check setting tools. Some machinery requires the use of additional
tools or keys to set, load or adjust the power tool. Before starting the power tool
always check to make sure they have been removed and are safely away from the
machine.
Prevent unintentional starting. Before plugging any machine into the power supply,
make sure the switch is in the OFF position. If the machine is portable, do not hold the
machine near the switch and look out when putting the machine down, that nothing
can touch the switch.

5
Carefully select an extension lead. Some machines are not suitable for use with
extension leads. If the tool is designed for outdoor use, use an extension lead also
suitable for that environment. When using an extended lead, select one capable
of handling the current (amps) drawn by the machine in use. Fully extend the lead
regardless of the distance between the power supply and the tool. Excess current
(amps) and a coiled extension lead will both cause the cable to heat up and can result
in re.
Concentrate and stay alert. Distractions are likely to cause an accident. Never
operate a power tool if you are under the inuence of drugs, including alcohol or if you
are feeling tired. Being disorientated will result in an accident.
Have this tool repaired by a qualied person. This tool is designed to conform to
the relevant international and local standards and as such should be maintained and
repaired by someone qualied, using only original parts supplied by the manufacturer.
This will ensure the tool remains safe to use.
Additional Safety Instructions for Impact Wrenches
Important: It is recommended that this machine should not be modied or used for any
application other than that for which it was designed.
Power tools shall not be used in potentially explosive environment unless specically
designed for that purpose.
Improper tool movement due to reaction forces or breakage of inserted tool or reaction
bar may cause injuries.
Power tools shall be isolated from the energy source before changing or adjusting the
inserted tool.
Warning!
There is a risk of crushing by torque between a reaction bar and the workpiece.
There is a risk of being injured if hands are not kept away from the reaction bar,
especially when unscrewing in conned work spaces.
There is a risk of danger to persons from high-speed splinters being emitted from
impact wrenches in the case of socket failure. Only use properly hardened impact
sockets with this machine.
Use only sockets and adaptors which are in good condition and are intended for use
with impact wrenches.
Adopt a suitable posture to counteract normal or unexpected movement of the power
tool due to reaction forces from the power assembly tool.
SAFETY INSTRUCTIONS

6
Impact wrenches are not torque wrenches and are not designed or capable of
installing fasteners to specied torque. For fasteners requiring a specic torque, install
the fastener to well below the required value then complete the task with a hand
torque wrench to avoid damaging the fastener or workpiece.
Ensure the anvil ring is correctly maintained and if damaged or missing, replace it
immediately before work commences. Missing or damaged anvil rings may lead to
sockets detaching from the wrench while rotating at high speed.
Only use accessories specically hardened for impact use. Do not use standard
chrome type hand tool sockets as they will shatter and splinter.
Do not modify this impact wrench in any way.
When starting or nishing the removal and installation of fasteners there is a risk of
cursing between the tool and the workpiece due to sudden movement or reaction
forces.
Residual risk
Important: Although the safety instructions and operating manual for our tools contain
extensive instructions of safe working with power tools, every power tool involves a
certain residual risk which can not be completely excluded by safety mechanisms.
Power tools must therefore always be operated with caution.

Stop the machine and push the switch to the left or right.
When the direction switch is pushed to the left, the drive will rotate clockwise.
When the switch is pushed to the right, the drive will rotate anticlockwise.
Before operation, check that the switch is set in the required position. Do not change
the direction of rotation until the wrench comes to a complete stop.
When the wrench is not in use move the direction switch to the neutral position (the
middle setting) to lock the trigger out.
Note: Failure to use the neutral position may activate the trigger inadvertently. This
inadvertent operation may cause the wrench to damaged.
Variable Speed Trigger
When the trigger is depressed, the drive will rotate (provided the direction switch is set in
the forward or reverse position). This trigger switch is electronic which enables the user
to vary the speed continuously.
The speed varies according to how far the trigger switch is depressed.
The further it is depressed, the faster the drive spindle will rotate.
The lighter it is depressed, the slower it will rotate.
Note: If the fastening is heavily corroded, or extremely tight, it may be necessary to
release the xing by hand before continuing with the wrench.
Always tighten xings to the correct torque as indicated by the manufacturer using
a calibrated torque wrench. Failure to do so may result in the xing damaged or
insu󰀩ciently tightened.

LED Worklight
To aid use in conned and inadequately lit spaces the LED worklight automatically
illuminates when the trigger is activated.
Variable Torque Selector
Output force can be varied by pressing the selector button to a desired level, this helps
to limit the output torque.
Operation
Proper fastening torque is determined by the kind of fastening, the size of the fastening
or the material or workpiece.
It is advisable to perform a test operation to determine the proper fastening time for
the fastening you are using.
Hold the wrench in straight alignment to the fastening.
Depress the wrench and use it in the required amount of time.
After fastening, always check the torque with an appropriate torque wrench.
Note:
Do not use this tool to install wheel nuts without a torque limiting device. Doing so
could result in galled or broken nuts.
Using a universal joint or extension bar may reduce the fastening force of the impact
wrench and require longer fastening time.
Using an impact wrench creates heat. The metal housing at the front of the wrench
will become hot. Under certain circumstances, the force required to tighten or remove
xings may cause the xings themselves to become very hot! Wear suitable gloves to
prevent burns.
