PROBLEMS
POSSIBLE CAUSES
REMEDIES
Tool runs at normal speed
but struggles under load.
Motor parts worn.
Piston sticking due to lack
of lubricant.
Check / have the parts checked and re-
pair / replace as necessary.
Check that the piston is well greased; add
grease where 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.
Piston Jamming
Pour air tool lubricating oil into air inlet,
operate tool in short bursts.
Tap motor housing gently with plastic mal-
let.
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.
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.

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 air hammer from the air supply before making adjustments, chang-
ing chisels 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.
Always ensure that the work-piece is firmly secured leaving both hands free to control
the air hammer.
Always wear safety goggles or glasses during operation.
Do not wear watches, rings, bracelets or loose clothing when using air tools.
Use as light weight a hose as possible from the tool to the wall or compressor cou-
pling.
In the interests of safety and possible damage to the tool/operator, always ensure
that the air hammer has stopped before putting it down after use.
Always ensure that the accessories such as chisels are rated / designed for use with
this air hammer as well as the required application, and are correctly and securely
fastened before connecting the tool to the air supply.
Do not carry or move the air hammer by its air hose.
Never allow the tool to come into contact with harsh solvents such as petrol.
