The following form lists the common operating issues with problems and solutions.
Please read the form carefully and follow it.
If any of the following symptoms occurs during your operation, stop using the tool immediately, or serious
personal injury could result. Only a qualified person or an authorised service centre should perform repairs
of the tool. Disconnect from the air supply before attempting repairs or adjustments. When replacing O-
rings etc. lubricate with air tool oil before assembly.
TROUBLESHOOTING
PROBLEMS
POSSIBLE CAUSES
REMEDIES
Tool runs at normal speed
but struggles under load.
Motor parts worn.
Check / have the parts checked and re-
pair / replace as necessary.
NOTE: Heat usually indicates insufficient
grease in gears. Severe operating condi-
tions may require more frequent lubrica-
tion.
Tool runs slowly. Air flows
slightly from exhaust.
Inlet filter restricted.
Motor parts jammed with
dirt particles.
Air flow blocked by dirt.
Check air inlet filter for blockage.
Pour air tool lubricating oil into air inlet,
operate tool in short bursts quickly reversing
rotation back and forth where applicable.
Repeat above as needed. If this fails return
to service centre.
Tools will not run. Air flows
freely from exhaust.
One or more motor vanes
stuck due to material build
up.
Pour air tool lubricating oil into air inlet,
operate tool in short bursts quickly reversing
rotation back and forth where applicable.
Tap motor housing gently with plastic mal-
let.
Disconnect supply; Free motor by rotating
drive shank manually where applicable
If tool remains jammed return to service
centre.
Tool will not shut off.
‘O’ rings throttle valve dis-
lodged from seat inlet
valve.
Replace ‘O’ ring or return to service centre.
Note: Repairs should be carried out by a qualified person.

SAFETY INSTRUCTIONS….cont
DO NOT
dismantle or tamper with the impact wrench, as this may be dangerous and
will invalidate the warranty.
If a problem with the impact wrench is experienced or suspected stop using the im-
pact wrench immediately and contact your distributor for repair.
Regularly inspect and lubricate the impact wrench, ensuring that it is in good working
order and condition.
Always ensure that the work area is clean and tidy, free from unrelated materials and
has adequate lighting.
Clean and stow the impact wrench correctly.
Failure to follow the warnings in this manual, may result in personal injury and/or prop-
erty damage.
DO
ensure that only compressed air is used to supply the air tool.
The compressed air supply MUST be at a suitable regulated pressure. Pipe work, reg-
ulators, hoses, isolation valves and connection devices MUST be suitable for the in-
tended application correctly installed and maintained in good condition by a com-
petent person.
Appropriate Personal protective equipment MUST be worn and MUST be designed to
protect against all hazards created. Severe permanent injury can result from using
inappropriate or insufficient protective equipment - Eyes in particular are at risk.
Long hair MUST be tied back; loose clothing MUST NOT be worn. There is a severe risk
of these being drawn in or trapped by the moving parts of the air tool.
Open or damaged compressed air lines present a significant ‘whip’ hazard; isolate
the problem hose from the air supply and repair / replace the hose immediately.
This air tool is electrically conductive DO NOT allow them to come into contact with
any source of electrical supply.
After use wait for the air tool to STOP completely before putting it aside.
When putting the air tool aside you MUST ensure that it placed in a stable position. To
avoid inadvertent operation DO NOT place the air tool where it can be knocked or
moved accidentally either directly or by the air connection hose.
If the air tool is not required or the air supply is interrupted, disconnect the air tool
from the air supply and place in secure storage to prevent unauthorised use.
Ensure the air valve (or trigger) is in the “off” position before connecting to the air sup-
ply.
Disconnect the impact wrench from the air supply before making adjustments,
changing impact wrench bits etc. and before servicing the tool.
Always keep your air tool clean and lubricated. Daily lubrication is essential to avoid
internal corrosion and possible failure.
Do not overload the tool. Allow the tool to operate at its optimum speed for maxi-
mum efficiency.
Do not increase the air pressure above the manufacturers recommended level, as
excessive pressure can cause the tool casing to split. This can also create excessive
wear on moving parts and possible failure.
