future reference. Make sure that you have read and understood theinstruction manual
before using thetool. Failure to follow thesafety instructions could lead to serious
personal injuries.
Warning: Do not exceed therecommended working pressure, 6.3 bar (90 psi).
Too high apressure can cause theimpact wrench to explode which may result in
serious or fatal personal injuries.
a) Disconnect theimpact wrench from theair 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 theimpact wrench is in use.
c) Do not pull thetrigger whilst theair 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 animpact wrench.
e) Do not pull thetrigger before thesocket has securely mated with thenut
or bolt. The socket must grip thehead of thebolt or nut securely.
f) Before using thetool, make sure that all connections are tight and that
theair hose is not damaged in any way.
g) WARNING: Always disconnect theair hose from theimpact wrench before
attaching thesocket/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.

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

Troubleshooting
The impact wrench
fails to deliver full
power or does not
rotate at all.
The tool is unlubricated. Lubricate thetool with appropriate
oil, refer to theLubrication section.
Low air pressure. Adjust thepressure regulator on
thecompressor to 90 psi/6.3 bar.
The function selector is in
thewrong position.
Check and adjust.
The pressure keeps falling. Air hose is too long or has too small
abore causing pressure drop.
Check and replace it with ashorter
hose or one with alarger bore.
Worn/broken rotor blades
in air motor.
Replace.
Water or spray blows out
of theexhaust.
Empty any condensation from
thetank and hose.
If theimpact wrench
has been left unused
for along time therotor
blades in theair motor
might have stuck.
Lubricate thetool with appropriate
oil, refer to theLubrication section.
