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 air supply.
■The tools shall not be used in explosive atmospheres
unless specially designed for that purpose.
■Always use ear protectors and wear safety glasses,
face mask or respiratory equipment.
■Do not wear watches, rings bracelets or loose clothing
when using air tools, and avoid drawing in or trapping
of long hair.
■Always ensure that the blade is designed for use with
the tool and ensure that the blade is properly clamped.
■Do not use blades which are cracked or deformed.
■Ensure you read, understand and apply safety
instructions before use.
■Keep children away from tools and workplaces.
■Do not overload the machine. Allow the tool to operate
at its optimum speed for maximum efficiency.
■In the interests of safety and prevent possible damage/
injury to the machine/operator, always ensure that the
machine has stopped before putting it down after use.
■Always ensure that the work piece is firmly secured
leaving both hands free to control the machine.
■Do not stop rotation of the disc by applying lateral
pressure on it.
■Make sure that the guard of the rotary saw blade,
if mounted on the saw, is in place and is correctly
mounted and functioning properly.
■Make sure that sparks, if emitted, are directed away so
as not to cause a hazard.
■Air tools are not generally insulated and should not
come in contact with electric power sources.
■The spare parts would not affect the health and safety
of the operator.

APPLICATIONS
This lightweight, slim-designed tool cuts curved surfaces
and tight circles with ease. The tool cuts all types of
aluminum, plastic, fiberglass, and metal. Other features of
the tool include: rear exhaust, rubber grip, safety trigger
to prevent accidental starts, safety frame at the head of
body saw. The product is for sawing only, 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.
■Required air pressure of 90psi, and an air flow
according to specification.
■Disconnect air tools from the energy source before
changing blades or making adjustments.
■Connect the tool to the air hose.
■Press 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.
■Release the start and stop device in case of failure of

the energy supply.
■For inserting the blade to the tool, insert the blade to
the no mar.
■Tighten the hex screw at no mar tip for securing the
blade.
■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. 5) 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.
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 5.
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
Drain the air tank daily. Water in the air line will
damage the tool.
■Clean air inlet filter weekly.
■Line pressure should be increased to compensate for
unusually long air hoses (over 8 metres). The hose
diameter should be 9.52 mm (3/8”) I.D.
■There is a risk of being injured by whipping compressed
air hose.
■Keep hose away from heat, oil and sharp edges. Check
hose for wear, and make certain that all connections
are secure.
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.
■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.
■Operate tool in short bursts quickly reversing rotation
back and forth where applicable.
■Repeat previous steps when needed.
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.
