Safety
General safety instructions for power tools
Warning: Readall theinstructions. Failure to comply with thefollowing instructions
can lead to electric shocks, fires and/or serious injury. Theterm “power tool”
in thewarning text below refers to your handheld mains operated or battery
operatedtool.
SAVE THESE INSTRUCTIONS.
1) Work area
a) Keep thework area clean and well illuminated. Cluttered and poorly lit areas
invite accidents.
b) Do not use power tools in explosive environments,e.g. near to flammable
liquids, gases ordust. Powertools create sparks which may ignite dust orfumes.
c) Keep children and bystanders away from thearea where you are using
thepowertool. Distractions can cause you to lose your concentration and control.
2) Electrical safety
a) Thepower tool’s plug must fit correctly into thewall socket. Nevermodify
theplug in anyway. Neveruse anadaptor plug together with earthed
powertools. Unmodified plugs and matching outlets will reduce therisk of
electricshocks.
b) Avoid physical contact with earthed objects such as pipes, radiators, ovens
and refrigerators. Thereis anincreased risk of electric shock if your body is
earthed.
c) Do not expose thepower tool to rain or other wet conditions. Waterentering
apower tool will increase therisk of electricshock.
d) Do not abuse themainslead. Neveruse thelead for carrying, pulling or
unplugging thepowertool. Keepthelead away from heat, oil, sharp edges
and movingparts. Damaged or tangled leads increase therisk of electricshock.

ENGLISH

e) When using power tools outdoors, use anextension lead that is suitable for
this purpose. Theuse of anextension lead designed for outdoor use decreases
therisk of electric shocks.
f) If using thepower tool in awet environment is unavoidable, awall socket
equipped with aportable residual current device (RCD) should beused.
Useof aRCD significantly reduces therisk of electricshock.
3) Personal safety
a) Pay attention to what you are doing and use common sense when using
powertools. Neveruse power tools 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
decreases therisk of injury.
c) Avoid accidental starts. Makesure that thepower switch is set to OFF before
plugging thepower tool into awall socket, fitting thebattery or picking up/
carrying thepowertool. Nevercarry apower tool with your finger on thetrigger
and never connect thepower tool to awall socket when theswitch is set to ON,
as this may result in bodily injury.
d) Remove all service tools/keys before switching on thepowertool. Aservice
tool left on arotating part of thepower tool may result in personal injury.
e) Do not overreach. Keepproper footing and balance at alltimes. Thisenables
better control of thepower tool in unexpected situations.
f) Wear suitable clothing. Donot wear loose-fitting clothing or jewellery.
Keephair, clothes and gloves away from movingparts. Loose-fitting clothes,
jewellery or long hair could become caught in movingparts.
g) If equipment for theextraction and collection of dust is available, make sure
it is connected and properlyused. Useof dust collection equipment can reduce
dust related hazards.
4) Use and maintenance of the power tool
a) Do not force thepowertool. Usethecorrect power tool for your application.
Thecorrect power tool will do thejob better and safer if used at therate for which
it was designed.
b) Never use thepower tool if thepower switch does not switch thetool
on andoff. Anypower tool that cannot be controlled by thepower switch is
dangerous and must be repaired.
c) Disconnect theplug from thepower source and/or thebattery pack from
thepower tool before making any adjustments, changing accessories or
storing thepowertool. Theseprecautions reduce therisk of thepower tool
starting unexpectedly.

ENGLISH

d) Storepower tools that are not being used out of children’sreach. Donot
allow people who are unfamiliar with thetool or its functions to operateit.
Powertools are dangerous in thehands of untrainedusers.
e) Maintain powertools. Checkfor misalignment, binding of moving
parts, broken parts or anything else which might affect theoperation of
thepowertool. Ifdamaged, have thepower tool repaired beforeuse.
Manyaccidents are caused by poorly maintained powertools.
f) Keep cutting tools sharp andclean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
g) Use thepower tool and any accessories in accordance with these instructions,
taking into account theworking conditions and thework to be performed.
Useof thepower tool for apurpose other than that for which it is intended could
result in adangerous situation.
5) Service
a) Repairs and service should only be performed by qualified tradesmen, and
only with original spareparts. This guarantees that thesafety of thepower tool is
maintained.
Specic safety instructions for impact wrenches
• Warning: Useonly sockets and accessories designed to be used with theimpact
wrench. Chrome-plated sockets and accessories are only designed for hand tools
and MUST NOT be used for impact wrenches. Thesecan fracture and cause
bodilyharm.
• Always unplug theimpact wrench before changing sockets. Unintended starts
pose arisk for hand injury.
• Themains lead should be checked regularly. Neveruse theimpact wrench if
themains lead or plug is damaged.
• If themains lead is damaged in any way it must be replaced by aqualified electrician.
• Any extension leads used must be designed for outdooruse. Usinganon-compliant
extension lead poses aserious danger.
• Protect theimpact wrench from rain or moisture.
• Unplug theimpact wrench from themains when not inuse.

Operating instructions
Preparations
• Warning: Parkthevehicle in gear and engage thehandbrake. Vehicles with
automatic gear boxes should be put into P(Park) and thehandbrake engaged
before attempting to lift thecar. Ensure that any wheels still in contact with
theground are securely blocked with wheel chocks to prevent them from moving.
• Read thecar’s owner’s manual if you are at all unsure on how to position thejack
under thecar.

ENGLISH

Things to consider
• Park thevehicle on afirm and stable surface.
• Use afloor jack which can support theweight of thevehicle by agood margin.
• Support thevehicle on axle stands if you need to go under thevehicle for any reason.
• Never place any body part under avehicle that is only being supported by floorjacks.
• Some vehicles may have different threads on thewheel nuts on theright- and
left-hand sides of thevehicle respectively. Checkthis before loosening thenuts in
order to avoid accidentally tighteningthem.
• Screw on thewheel nuts/bolts by hand, using at least 3 complete rotations in
order to prevent possible thread damage when tightening with theimpact wrench.
Loosening the wheel nuts/bolts
1. Attach an 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). Use a hexagon impact
socket.
2. Fit the socket fully over the nut/bolt you wish
to loosen.
3. Hold the impact wrench firmly with one hand
around the front part of the tool, hold the
handle (7) with the other hand.
4. Press in the selector (6) for anticlockwise
rotation of the socket (to loosen the bolt).
Note: Do not use the impact wrench for
more than 15 seconds 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 (6) 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 the wheel nuts/bolts
Note: When tightening wheel nuts/bolts, 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 the wheel could be damaged.
1. Attach a hexagon impact socket which fits exactly onto the head of the screw/bolt
or nut which you want to undo.
2. 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.
3. Fit the socket fully over the nut/bolt you wish to tighten. Always start with the lower
nut/bolt (see below pictures).
4. Hold the impact wrench firmly with one hand around the front part of the tool, hold
the handle (7) with the other hand.
5. Press in the selector (6) for clockwise rotation of the socket (to tighten the bolt).
6. Lower the jack so that the vehicle is standing on the ground.
Warning: Useatorque wrench to check that thewheels are fastened to
therecommended torque setting before using thecar after changing its wheels.
Note: Tighten thewheel nuts/bolts in thecorrectorder. Belowis anexample of
both a4- and 5-bolt wheelsetup.
