Foreseen Use of the Tool
This tool is designed to be used with flat reinforced resin 4 ins dia max.
discs having a speed rated above 14,000 rpm. The bore size of the disc
is 3/8 ins.
The tool should not be used with any other type or rating of abrasive disc
or wheel. It must never be used with saw blades or other cutting
devices.
Do not use the tool outside the design intent. Never modify the tool for
any other purpose, or for its use as a disc cutter without first seeking
advice from the manufacturer or an authorised representative.
Putting Into Service
Air Supply
Use a clean lubricated air supply that will give a measured air pressure
at the tool of 90 p.s.i./6.3 bar when the tool is running with the
trigger/lever fully depressed. Use recommended hose size and length.
It is recommended that the tool is connected to the air supply as shown
in figure 1. Do not connect the tool to the air line system without
incorporating an easy to reach and operate air shut off valve. The air
supply should be lubricated. It is strongly recommended that an air filter,
regulator, lubricator (FRL) is used as shownin Figure 1 as this will supply
clean, lubricated air at the correct pressure to the tool. Details of such
equipment can be obtained from your supplier. If such equipment is not
used then the tool should be lubricated by shutting off the air supply to
the tool, depressurising the line by pressing the trigger on the tool.
Disconnect the air line and pour into the intake bushing a teaspoonful
(5ml) of a suitable pneumatic motor lubricating oil preferably
Work Stations

always recommended that the tool is used when standing on a solid
floor. It can be used in other positions but before any such use the
operator must
be in a secure
position
having a firm
grip and
footing and be

Operating
The lever is the on/off valve for the tool. Connect to a suitable air supply
and ensure that the airpressure, measured at the tool inlet, with the tool
running does not exceed 90 psi (6.3 bar). Select disc and ensure that
the disc is not cracked or damaged and that the speed rating of the disc
is in excess of 14,000 rpm. Using only the wheel spacer supplied with
the tool, fit the disc and tighten wheel screw while holding flange. Do
not over tighten as this could crack the disc. Ensure wheel is in place.
When first starting the tool with a new or changed disc the tool should
be first started in a protected area i.e. such as under a heavy bench and
run for say a minimum time of one minute. This will provide protection if
the wheel should break because a fault was not detected. Always use
eye protection and wear protective gloves if there are sharp edges in
the working area. Remember that the cutting process will generate
heat and that cut parts, particularly small items can get very hot and
burn fingers if touched. Allow cut parts to cool.
The tool and the work process may create a noise level such that ear
protectors should be worn. The cutting process will create dust and the
use of breathing masks is recommended. Check that the material being
cut will not cause harmful dust or fumes. If this is so then special
breathing apparatus may be required. Seek advice before starting work.
The cutting process will create sparks. Ensure that these do not create
a hazard to any person, object or process and are not directed near any
flammable materials or fluids. Do not use the cutter in explosive
environments. Do not apply excessive loads to the tool as this will
reduce the efficiency of the disc. Apply light loads and allow the wheel
to cut. Try always to keep the disc square to the cut. Do not apply side
loads or grind on the side of the disc.
Handle the cutter with care. If the cutter is dropped carefully examine
the disc for damage and replace if necessary. Start the tool as for the
first time of fitting a disc, i.e. under a bench. Make sure that the object to
be cut is in a firm fixed position.
incorporating a rust inhibitor. Reconnect tool to air supply and run tool
slowly for a few seconds to allow air to circulate the oil. If tool is used
frequently lubricate on daily basis and if tool starts to slow or lose power.
It is recommended that the air pressure at the tool whilst the tool is
running is 90 p.s.i./6.3 bar.

repairs.
11) Do not lock, tape, wire, etc. the on/off valve in the run position. The
trigger/lever etc. must always be free to return to the ‘off’ position
when it is released.
12) Always shut off the air supply to the tool, and depress the
trigger/lever etc. to exhaust air from the feed hose before fitting,
adjusting or removing the working attachment.
13) Check hose and fittings regularly for wear. Replace if necessary. Do
not carry the tool by its hose and ensure the hand is remote from the
on/off control when carrying the tool with the air supply connected.
14) Take care against entanglement of moving parts of the tool with
clothing, ties, hair, cleaning rags, etc. This will cause the body to be
drawn towards the tool and can be very dangerous.
15) It is expected that users will adopt safe working practices and
observe all relevant legal requirements when installing, using or
maintaining the tool.
16) Do not install the tool unless an easily accessible and easily operable
on/off valve is incorporated in the air supply.
17) Take care that the tool exhaust air does not cause a problem or
blows on another person.
18) Never lay a tool down unless the working attachment has stopped
moving.
19) A cutting wheel should only be fitted by a competent person trained
to do so. The wheel must be of the correct size and speed rating. Never
use tool with guard not fitted.
20) Check the speed of the tool at least once per week, if it is in regular
use, with an accurate tachometer.
21) The tool must only be used with the cutting wheels as set out in
section “Foreseen Use of the Tool” and shown on parts list. Never fit any
other device.
22) Carry out the instructions as set out in “Putting into Service”.
23) Many countries have local or national rules re the use and fitting of
cutting wheels. Make sure such rules are observed.
24) Use a barrier to prevent sparks causing a hazard to the operator,
any other person or anything within the vicinity of the sparks.
25) If a wheel guard becomes damaged or has withstood a wheel
breakage, the guard must be changed.
26) Do not use chipped or cracked cutting wheels.
27) Always wear impact resistant eye protection.
28) Use only washer (54) provided with the tool for locating and
clamping the wheel. Never use substitutes. Use the paper blotter fixed
to the wheel as this ensures even tightness when the wheel is secured.
29) Tighten the wheel plates sufficiently to prevent wheel spin off when
the tool is turned off. Do not tighten excessively as this may crack the
wheel.
30) The noise from the tool or the process noise of the cutting operation
may be such that hearing protection should be worn.
31) Avoid inhaling dust from the cutting process. Wearing of a
breathing mask is recommended. Cutting certain materials may mean
that special breathing precautions are necessary. Seek advice before
using the tool.
32) Always ensure that the work piece is firmly supported so that it
cannot move during the cutting process.
33) If the tool is dropped do not use unless the wheel is first checked for
damage by a competent person.
34) When not in use the tool should be stored in a safe place where it
will not be damaged. If a tool has not been used for a period of time
check the tool as for the first time of using.
35) Be aware that if the cutting process causes high vibration, special
precautions should be taken.
36) The operator should be aware that the cutting wheel will continue
to rotate after the power supply has been shut off. This could cause a
hazard.
37) Always store cutting wheels in accordance with the manufacturer’s
instructions.
38) Check frequently that the spindle thread has not become damaged
or worn.
39) Always ensure that the cutting wheel has a higher permissible
running speed to the speed of the tool.
