A wrench or a key
left attached to a rotating part of the power tool may result in personal injury.
This enables better control of
the power tool in unexpected situations.
Loose clothes, jewellery or long hair can be caught in moving parts.
Use of these devices can reduce dust-related hazards.
Power tool use and care
The correct
power tool will do the job better and more safely at the rate for which it was designed.
Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
Such
preventive safety measures reduce the risk of starting the power tool accidentally.
Power tools are
dangerous in the hands of untrained users.
Many accidents are caused by poorly maintained
power tools.
Properly maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
Use of the power
tool for operations different from those intended could result in a hazardous situation.
Service
This will ensure that the safety of the power tool is maintained.
SAFETY GUIDELINES
Work area safety
Cluttered or dark areas invite accidents.
Power tools create sparks, which may ignite the dust or fumes.
Distractions can cause
you to lose control.
Electrical safety
Unmodified plugs and matching
outlets will reduce the risk of electric shock.
There is an increased risk of electric shock if your body is earthed or grounded.
Water entering a power tool will increase
the risk of electric shock.
Damaged or
entangled cords increase the risk of electric shock.
Use of a cord suitable for outdoor use reduces the risk of electric shock.
Use of a GFCI reduces the risk of electric shock.
Personal safety
A moment of inattention while operating power tools may result in serious personal injury.
Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or hearing protection, used for appropriate conditions,
will reduce personal injuries.
Carrying power tools
with your finger on the switch or energising power tools that have the switch on invites accidents.

The proper fastening torque may differ depending on
the type of size of the bolt.
Vibration caused by hammer-drill or Impact wrench action may be harmful to your hands and arms.
Tools equipped with shut-off clutches are not designed for drilling
applications. The output drive can shut off automatically and without warning.
There is a risk of the tool sliding off the fastener head,
depending on type of socket or bit used. First test the fastening time of a fastener and pay attention
during the screw-driving process to ensure you do not injure yourself if the tool bit or socket slides
off of the fastener.

Installing and removing the
socket (fig 1)
WARNING!
Always verify that the tool is switched
off and unplugged before installing
any accessories on the tool.
Always use the correct size socket for bolts and
nuts. An incorrect socket will result in inaccurate
and inconsistent fastening torque and/or damage
to the bolt or nut.
1. To install the socket, push it onto the output drive of the tool until it locks into place.
2. To remove the socket, simply pull it off.
Turning the impact wrench on
(fig 2)
1. Connect the power cord of your impact
wrench to a standard household power outlet.
2. Press the part of the switch marked “F” to run
the tool in the forward direction (clockwise
rotation). Use this direction for tightening bolts
or nuts.
3. Press the part of the switch marked “R” to
reverse the motor direction (counter-clockwise rotation). Use this direction for loosening bolts or
nuts.
4. Release the switch to stop the tool.
5. Keep the switch pressed for continuous operation.

Impacting tips
The proper fastening torque may differ depending on the type or size of the bolt, the material of the
workpiece to be fastened, etc.
Hold the tool straight along the axis of the bolt or nut.
Excessive fastening torque may damage the bolt/nut or socket. Before starting your job,
always perform a test operation to determine the proper fastening time for your bolt or nut.
Practice with various fasteners, noting the length of time required to reach the desired torque. Check
the tightness with a hand-torque wrench. If the fasteners are too tight, reduce the impacting time. If
they are not tight enough, increase the impacting time.
Hold the tool firmly, and place the socket over the bolt or nut. Turn the tool on, and fasten the bolt or nut
to the proper torque.
The torque that is required to loosen a fastener averages 75% to 80% of the tightening torque,
depending on the condition of the contacting surfaces. However, if rust or corrosion causes seizing,
more torque may be required.
After fastening, always check the torque with a torque wrench. The fastening torque is affected by a
wide variety of factors, including the following:
A voltage reduction will cause a reduction in the fastening torque.
Failure to use the correct size socket will cause a reduction in the fastening torque.
A worn socket (wear on the hex end or square end) will cause a reduction in the fastening torque.
Although the torque coefficient and the class of bolt may be the same, the proper fastening torque
will differ according to the diameter of the bolt.
Even if the diameters of bolts are the same, the proper fastening torque will differ according to the
torque coefficient, the class of bolt and the bolt length.
• The use of a universal joint or an extension bar (both available separately) will reduce the fastening
force of the impact wrench somewhat. Compensate by fastening for a longer period of time.
• The manner of holding the tool or the material to be fastened will affect the torque.
Installing fasteners
Always keep the Impact wrench at a right angle to the fastener to avoid damaging the
fastener head.
1. Start threading the fastener by hand onto or into its threaded counterpart (e.g. nut onto bolt, or bolt
into nut or threaded hole).
2. With the proper impact socket securely mounted to the wrench, slide the impact socket onto the
nut or bolt head.
3. Firmly hold the tool and depress the switch at “F”. The impact socket will turn the fastener and
impacting will begin once the fastener encounters resistance.
WARNING!
Do not over-tighten, as the force of the Impact wrench can break the fastener.
1. With the proper impact socket securely mounted to the wrench, slide the impact socket onto the
bolt head.
2. Firmly hold the tool and depress the switch at “R”. The tool will start to impact immediately.
3. Once the fastener has “broken loose,” it will start to unthread. Be careful that you do not allow
a fastener to spin freely once it is no longer engaged with its threaded counterpart, as it may be
thrown out of the socket.
