Please read theentire instruction manual before using theproduct and then save it for
future reference. We reserve theright for any errors in text or images and any neces-
sary changes made to technical data. In theevent of technical problems or other
queries, please contact our Customer Services (see address details on theback).
Safety
Warning: Read theentire instruction manual before using theproduct and keep it for
future reference. Make sure that you have read and understood theinstruction manual
before using thetool. Failure to follow thesafety instructions could lead to serious
personal injuries.
Warning: Do not exceed therecommended working pressure, 6.3 bar (90 psi).
Too high apressure can cause theimpact wrench to explode which may result in
serious or fatal personal injuries.
a) Disconnect theimpact wrench from theair hose before changing sockets/
tools, before servicing it, and as soon as you have finished using it.
b) Always wear safety glasses and ear defenders when theimpact wrench is in use.
c) Do not pull thetrigger whilst theair hose is being connected.
d) Only use tools and accessories designed for use with pneumatic/air powered
tools. Warning: Only use impact sockets which are designed for use with
impact wrenches. Normal sockets designed for use with hand tools, worn
sockets or damaged sockets should never be used with animpact wrench.
e) Do not pull thetrigger before thesocket has securely mated with thenut
or bolt. The socket must grip thehead of thebolt or nut securely.
f) Before using thetool, make sure that all connections are tight and that
theair hose is not damaged in any way.
g) WARNING: Always disconnect theair hose from theimpact wrench before
attaching thesocket/accessory and before carrying out any maintenance.
h) Neither this tool nor its accessories must be modified in any way.
Workplace hazards
a) Keep your work area clean and well-illuminated.
b) The most common causes of serious or fatal injury in theworkplace are related to
slipping, tripping or falling. Watch out for hanging cables or hoses and slippery floors.

c) Keep afirm footing and good balance at all times.
d) Repetitive work movements, uncomfortable work postures and vibrating
tools can be harmful to hands and arms.
e) Exposure to high noise levels can cause permanent hearing loss. Always use
ear protection.
f) Avoid inhaling dust particles or contaminants which might be harmful to
your health.
g) Keep pets and bystanders out of thework area when thetool is being used.
h) This tool is not designed for use in explosive atmospheres and is not
insulated for contact with electric power sources.
Personal safety precautions
a) Pay attention to what you are doing and use common sense when using
pneumatic tools. Never use any hand tool, pneumatic or power tool if you are
tired or under theinfluence of drugs, alcohol or medication. One moment of
inattention while using apower tool may result in serious injury.
b) Wear protective clothing. Always wear safety glasses. Using protective
clothing such as dust masks, non-slip safety shoes, helmets and ear defenders
when needed decreases therisk of injury.
c) Avoid accidental starts. Never hold your finger on thetrigger when connecting
theair hose or changing asocket.
d) Do not overreach. Make sure you stand steady and well balanced at all times.
This will allow you to have more control in unexpected situations.
e) Do not wear loose-fitting clothing or jewellery. Keep hair, clothes and loose-
fitting gloves away from moving parts. Loose-fitting clothes, jewellery or long
hair could become caught in moving parts and result in serious injury.
f) Dust extraction or collection equipment should be used whenever thework
environment contains large amounts of dust.
g) Hold theproduct by its insulated gripping surfaces whenever using thetool
where it could come in contact with hidden live wiring. Contact with live wires
will make themetal parts of thetool live and could shock theuser.
h) Avoid direct contact with accessories during use.

Installation
Air hose connector
1. If aplug has been fitted to theair
coupling (6) to protect it during ship-
ment from thefactory it must now
be removed.
2. Screw theincluded air inlet nipple
into theair inlet coupling. Use some
form of thread sealant to ensure that
theseal is airtight.

ENGLISH

3. Fit asocket onto theanvil (1). Use
only undamaged impact sockets.
4. Connect thequick-connect coupling
of theair hose to theair inlet nipple on
theimpact wrench.
Connection to the air supply system
a) This tool must only be connected to aclean, filtered and dry air supply which
provides anair pressure at thetool of 6.3 bar (90 psi). Warning: Too high apressure
will reduce thelifespan of thetool and could cause serious personal injuries.
b) Connect thetool to theair supply using ahose designed for high pressure air.
c) Fit aquick-connect coupling in theair hose and aregular inlet nipple onto theimpact
wrench. Do not attach aquick-connect coupling to theimpact wrench itself, as this
would retain pressure in thetool even when theair hose has been disconnected.
d) In order for thetool to work at its full capacity, theair compressor must provide
thetool with at least thetool’s rated air consumption.
e) Only use air hoses of therecommended dimension and length. Do not connect
thetool to theair compressor without incorporating aneasy to reach and operate
air cut-off valve.
f) Make sure that any water which has condensed in thetank of theair compressor
or theair hoses is emptied out regularly to prevent water being delivered into
thetool. Water in thesystem could freeze in thehose or cause thetool to rust.
Motor and impact mechanism lubrication
Themotor and theimpact mechanism are lubricated with grease
from thefactory but might need to be lubricated further if theimpact
is used daily. Add 4–5 drops of oil designed for air tools and
machines into theair coupling nipple on theimpact wrench before
connecting theair hose. Repeat after every 3–4 hours of use.
Run theimpact wrench for afew seconds under no load with
arag over theexhaust port to catch any excess oil.

Instructions for use
Undoing nuts/bolts
1. Fit ahexagon impact socket which fits exactly onto thehead of thescrew/bolt or
nut which you want to undo onto theanvil of theimpact wrench (1).
2. Fit thesocket fully over thenut/bolt you wish to loosen.
3. Grip theimpact wrench firmly by thehandle (3).
4. Turn theselector (5) left to thereverse position (R) and choose
animpact force 1, 2 or 3 (low–medium–high). Always begin
with thelowest force (1) and then increase if necessary.
5. Pull thetrigger (2).
Note: Do not run theimpact wrench for more than 15 sec at
atime in thesame direction if thenut/bolt does not loosen. If
thenut/bolt does not come undone:
• Change thedirection of rotation using theselector (3)
and drive theimpact wrench in theopposite direction for
acouple of seconds.
• Switch thedirection of rotation back again and run
thewrench in theoriginal direction.
Tightening nuts/bolts
Note:
• When doing up nuts/bolts using animpact wrench, atorque bar (sold separately)
with thecorrect torque setting should be inserted between theimpact wrench and
theimpact socket, otherwise thenut/bolt might be overtightened and damage
thefastener and/or thematerial it is fastening.
• When fitting wheels onto vehicles afinal check of thewheel nut/bolt torque should
always be made using atorque wrench.
1. Screw thewheel nuts/bolts in place by hand at least 3 complete turns in order to
prevent damaging thethreads when they are tightened using theimpact wrench.
2. Fit ahexagon impact socket which fits exactly onto thehead of thescrew/bolt or
nut which you want to undo onto theanvil of theimpact wrench (1).
3. Fit thesocket fully over thenut/bolt you wish to loosen.
4. Grip theimpact wrench firmly by thehandle (2).
5. Turn theselector (3) right to theforward position (F) and choose animpact force
1, 2 or 3 (low–medium–high). Always begin with thelowest force (1) and then
increase if necessary.
6. Squeeze thetrigger and release it when thenut/bolt has been tightened.
Note: After fastening, afinal check of thetorque should always be made using
atorque wrench.

Troubleshooting
The impact wrench
fails to deliver full
power or does not
rotate at all.
The tool is unlubricated. Lubricate thetool with appropriate
oil, refer to theLubrication section.
Low air pressure. Adjust thepressure regulator on
thecompressor to 90 psi/6.3 bar.
The function selector is in
thewrong position.
Check and adjust.
The pressure keeps falling. Air hose is too long or has too small
abore causing pressure drop.
Check and replace it with ashorter
hose or one with alarger bore.
Worn/broken rotor blades
in air motor.
Replace.
Water or spray blows out
of theexhaust.
Empty any condensation from
thetank and hose.
If theimpact wrench
has been left unused
for along time therotor
blades in theair motor
might have stuck.
Lubricate thetool with appropriate
oil, refer to theLubrication section.
Then run thetool on High impact
force for about 30 seconds.
Refer to Operating instructions.
If this doesn’t help, repeat
theprocedure.
