2. Remove the protective plug from the air inlet
3. Using a spanner (not included) screw the quick connector into the air inlet
located at the base of the handle
4. Connect to airline, pressurise carefully and carry out a leak check (e.g. by
spraying small amounts of soapy water on to the outside of the connectors)
• Air lines fitted with matching female quick connectors will now be a push fit
to the tool
Fitting the auxiliary handle
WARNING: To ensure operator safety, ALWAYS use the Auxiliary Handle (8).
1. Screw the auxiliary handle clockwise into the mounting point on the left side
of the tool housing. Tighten by hand
2. To remove the auxiliary handle, unscrew anti-clockwise
Fitting a disc
WARNING: Disconnect the tool from the air supply before fitting or changing discs.
• Find the flat faces on the Spindle (3) and engage them with the Spanner (7), so
that the spindle is held securely and not able to rotate
• Use the Pin Spanner (6) to loosen the Threaded Flange (4)
• Remove the threaded flange and discard the old disc if fitted
• Fit a new disc of correct size (see 'Specifications'), following the manufacturer's
guidance for direction of rotation
Note: Unless otherwise stated, the metal ring at the centre of the disc should face
the spindle.
• Re-fit the threaded flange, ensuring it is not deformed, burred or notched, and
tighten using the spanner and pin spanner
WARNING: A damaged flange may cause irregular pressure on the disc, and may
cause it to break.
WARNING: DO NOT overtighten. The direction of rotation will prevent the bolt from
becoming loose.
• Spin the disc by hand to check it is secure and correctly aligned

LEADER HOSE
• This tool should be connected to a clean, dry air supply with inline oiler and
water separator
• Do not allow supply pressure to exceed the maximum stated (see
'Specifications')
• Ensure that water is drained from air system daily
• Ensure all parts of the system (hoses, couplers, etc.) are correctly rated for the
air pressure to be used
Setting tool power
• The maximum tool speed/power can be adjusted by reducing/increasing the air
supply pressure within the range specified in 'Specifications'
• Whilst working with the tool, speed adjustments can be made via the Speed
Control Trigger (10)

Operation
WARNING: DO NOT switch the machine on/off when the disc is in contact with
the workpiece. Always allow the motor to reach its full speed before applying load,
and to stop completely before placing the grinder down. Always hold the machine
securely, using both hands, on the handles provided.
1. Hold the tool by its Handle (1) and turn it so the open side of the Guard (2) is
facing away from you. Your thumb should wrap around the handle and your
fingers should sit on the Speed Control Trigger (10)
2. Disengage the Safety Catch (9) and gently squeeze the trigger towards the
handle
3. The Grinding Disc (5) will begin to spin. Squeeze the trigger further to
increase the speed; slightly release to decrease the speed
4. With the disc spinning at the required speed, slowly move the disc towards
the workpiece, and gently engage the material
WARNING: When the disc begins to cut/grind, it will force the tool to move
sideways. Make sure you have a firm grip on the tool and are ready to counteract
this.
5. As the disc begins to cut/grind, take note of the direction in which the waste
material is being ejected. It should be directed away from you, and not
towards any person or object to which it may cause damage
6. To stop the tool, remove the disc from the workpiece, fully release the trigger
and allow the safety catch to re-engage
Note: DO NOT allow the tool to run in 'idle rotation' for an extended period of time.
This will shorten its life.
WARNING: Be aware that air tools may hold residual pressure after use. Always
bleed air pressure from the tool after shutting off air supply.
Grinding
• Only use discs specifically manufactured for grinding operations. Stone and
metal grinding discs are not interchangeable; use the correct disc for your
application
• When grinding, hold the tool at a 15° to 30° angle to the surface of the
workpiece (Fig. A)
Note: Do not apply too much pressure to the machine whilst grinding. Excessive
pressure does not result in more effective removal of material, but will cause
premature wear of the grinding disc and increased wear and tear on the machine.
Cutting
• Only use discs specifically manufactured for cutting operations. Stone and metal
cutting discs are not interchangeable, use the correct disc for your application
• Never use cutting discs for grinding operations. The disc might shatter and
produce projectiles that could injure the operator and bystanders
• When cutting, always keep the angle of the disc constant. Do not apply any
sideways force to cutting discs, as this might lead to the disc becoming jammed
in the cut and shatter
WARNING: Do not apply too much pressure to the machine whilst cutting.
Excessive pressure does not result in more effective or faster cutting, but will in
fact cause premature wear of the cutting disc and increase wear and tear on the
machine.
Note: The cutting disc will wear during use, and the disc diameter will gradually
reduce in size. The smaller the disc becomes, the more strain will be placed on
the motor. To avoid damage to the machine, only use cutting discs that are within
approximately 25% of the original size.
