GENERAL SAFETY RULES
■Always wear personal protective safety glasses,
gloves, ear protectors, face mask or respiratory
equipment and protective clothing.
■Always ensure machine is switched off before
connecting to air supply.
■Disconnect any machine from the air supply before
changing blades or discs, and before servicing any
type of machine.
■Do not wear watches, rings bracelets or loose clothing
when using air tools.
■Do not overload the machine. Allow the tool to operate
at its optimum speed for maximum efficiency.
■Do not increase the air pressure above the
manufacturers recommended level, as excessive
overload can cause the machine casing to split. Also
this creates excessive wear on moving parts and
possible failure.
■In the interests of safety and possible damage to the
machine/operator, always ensure that the machine
has stopped before putting it down after use.
■Always ensure that the accessories such as blades,
discs, sockets, etc. are rated/designed for use with the
machine. Also correctly and securely fastened before
connecting the machine to the air supply.
■Ensure you read, understand and apply safety
instructions before use.
■Keep children away from the tool and workplaces
when using the tools.
■Air tools are not generally insulated and should not
come in contact with electric power sources.
■Polishers and sanders should not be used in a
potentially explosive environment.
■Pay attention to the risk of explosion or fire due to the
material being processed.
■Pay attention to the risk of cutting.
■Pay attention to the risk of hair or loose clothing being
drawn in or trapped in the tool.
■Pay attention to the whipping compressed air hose.
■Check that the maximum operating speed of the
inserted tool (flap wheels, abrasive belts, fibre discs
etc.) is higher than the rated speed of the air tool.
■Check the speed after each service in relevant cases.
■Special care has to be taken when assembling the
speed governor or protective devices.
■The spare parts would not affect the health and safety
of the operator.
■Personal protection and dust collection device should
be used with regard to the material being worked upon.

APPLICATIONS
The tool is ideal for smoothing concrete, removing burrs
from metal and for finishing weld seams. It features a
rugged die-cast aluminum body and an ergonomic rubber
grip. It has built-in regulator for positive speed control,
screened inlet to prevent dirt particles from entering air
intake. Any other use is forbidden.
AIR SUPPLY AND OPERATION
■Ensure air valve (or trigger) is in the “off” position
before connecting to the air supply.
■Connect the air tool to the air hose .
■Press the trigger to operate the tool.
■DO NOT use any additional force upon the
tool.
■DO NOT allow tool to free run for an extended period
of time as this will shorten its life.

English
■Release the start and stop device in the case of an
interruption of the energy supply.
■Disconnect tools from the energy source
before changing accessories or making
adjustments.
■The flow of air may be regulated by adjusting flow
valve at the base of the handle.
■Required air pressure of 90psi, and an air flow
according to specification.
■For inserting the polished section to the tool, insert
the rear washer and exhaust washer with the polished
section.
■Using straight wrench and wrench for tighten the
washers for securing the polished section.
■Apply straight wrench on the inside "D" shape of the
spindle shaft.
■Apply wrench on the directions to tighten or lossen.
■Before operation, ensure the inserted tool is fixed in
tool.
WARNING
Ensure the air supply is clean and does not exceed
90psi while operating the tool. Too high an air pressure
and unclean air will shorten the product life due to
excessive wear and may be dangerous, causing
damage and/or personal injury.
LUBRICATION
An automatic in-line filter-regulator-lubricator is
recommended (Fig. 7) as it increases tool life and keeps
the tool in sustained operation. The in-line lubricator
should be regularly checked and filled with air tool oil.
Proper adjustment of the in-line lubricator is performed by
placing a sheet of paper next to the exhaust ports and
holding the throttle open approximately 30 seconds. The
lubricator is properly set when a light stain of oil collects
on the paper. Excessive amounts of oil should be avoided.
If it becomes necessary to store the tool for an extended
period of time (overnight, weekend, etc.), it should receive
a generous amount of lubrication at that time. The tool
should be run for approximately 30 seconds to ensure oil
has been evenly distributed throughout the tool. The tool
should be stored in a clean and dry environment.
●It is most important that the tool be properly
lubricated by keeping the air line lubricator filled
and correctly adjusted. Without proper lubrication
the tool will not work properly and parts will wear
prematurely.
●Use correct lubricant in the air line lubricator. The
lubricator should be of low air flow or changing air
flow type, and should be kept filled to the correct
level. Use only recommended lubricants, specially
made for pneumatic applications. Substitutes may
harm the rubber compounds in the tools O-rings
and other rubber parts.
IMPORTANT!
See Figure 7.
If a filter/regulator/lubricator is not installed on the air
system, air operated tools should be lubricated at least
once a day or after 2 hours work with 2 to 6 drops of oil,
depending on the work environment, directly through
the male fitting in the tool housing.
LOADING AND OPERATION
WARNING
If any of the following symptoms appears during your
operating, stop using the tool immediately, or serious
personal injury could result. Only qualified persons or
an authorized service center can perform repairs or
replacement of tool.
■Clean air inlet filter weekly.
■Line pressure should be increased to compensate for
unusually long air hoses (over 8 metres). The minimum
hose diameter should be 6.35 mm (1/4”) I.D. and fittings
must have the same inside dimensions.
■Keep hose away from heat, oil and sharp edges. Check
hose for wear, and make certain that all connections
are secure.
■Release the start and stop device in the case of energy
supply failure.
■Use only accessories recommended by the
manufacturer of the tools are used.
■WARNING! Grinding wheels and cutting off tools shall
not be used.
MAINTENANCE
■Keep the tool safe by regular maintenance.
■Always keep your air tool clean and lubricated. Daily
lubrication is essential to avoid internal corrosion and
possible failure.
■Maintenance shall be taken weekly.
■Drain the air tank daily. Water in the air line will
damage the wrench.
■If the tool cannot be used anymore, make sure to
dispose of it so as not to impose hazards on people

and the environment.
■Only lubricants (air tool white oil) recommended by the
manufacturer should be used.
TROUBLESHOOTING
WARNING
If any of the following symptoms appears during your
operating, stop using the tool immediately, or serious
personal injury could result. Only qualified persons or
an authorized service center can perform repairs or
replacement of tool.
Disconnect tool from air supply before attempting repair or
adjustment. When replacing O-rings or cylinder, lubricate
with air tool oil before assembly.
PROBLEM: Tool runs at normal speed but fails under
load.
POSSIBLE CAUSES
■Motor parts worn.
■Cam clutch worn or sticking due to lack of lubricant.
REMEDIES
■Lubricate clutch housing.
■Check for excess clutch oil. Clutch cases need only
be half full. Overfilling can cause drag on high speed
clutch parts, ie. a typical oiled/lubricated tool requires
1⁄2 ounce of oil.
Grease lubrication
NOTE: Heat usually indicates insufficient grease in
chamber. Severe operating conditions may require
more frequent lubrication.
PROBLEM: Tool runs slowly. Air flows slightly from
exhaust.
POSSIBLE CAUSES
■Motor parts jammed with dirt particles.
■Power regulator in closed position.
■Air flow blocked by dirt.
REMEDIES
■Check air inlet filter for blockage.
■Pour air tool lubricating oil into air inlet as per
instructions.
■Operate tool in short bursts quickly reversing rotation
back and forth where applicable.
■Repeat above as needed.
PROBLEM: Tools will not run. Air flows freely from
exhaust
POSSIBLE CAUSE
One or more motor vanes stuck due to material build
up.
REMEDIES
■Pour air tool lubricating tool into air inlet.
■Operate tool in short bursts of forward and/or reverse
rotation where applicable.
■Tap motor housing gently with plastic mallet.
■Disconnect supply. Free motor by rotating drive shank
manually where applicable
■If tool remains jammed return to service centre.
PROBLEM: Tool will not shut off.
POSSIBLE CAUSE
‘O’ rings throttle valve dislodged from seat inlet valve.
REMEDY
Replace ‘O’ ring .
NOTE: Repairs should be carried out by a qualified
person.
