Foreseen Use of Tool
The spindle thread on this tool is M6 and is designed to be used as a
polisher by use of a velcro backing pad and appropriate wool and
sponge buffs. Do not use the tool for any other purpose than a polisher.
Do not fit any other type of pad or abrasive or cutting device.
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 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
shown in Figure 1 as this will supply clean,
lubricated air at the correct pressure to the
Work Stations
The tool should only be used as a handheld, hand operated tool. It is
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 oper-
ator must be in a secure position having a firm grip and footing and be
aware of a reaction force on the hand as result of the tool doing work.

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 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. The tool can run at lower and higher
pressures with the maximum permitted working air pressure of 100
p.s.i./7 bar.

Operating
Select a suitable polishing pad or buff (see Section "Foreseen use of the
tool") and make sure that it is fixed securely to the tool. Connect to
suitable air supply as recommended.
Apply the polisher lightly to the work and allow the tool to do the work.
Take great care when polishing around sharp edges and surfaces to
avoid the disc snagging i.e. the disc may be brought to an abrupt stop or
considerably slowed that will cause the tool to kick in the hands.
It is always recommended to use safety glasses and a breathing mask.
The polishing of certain materials may create a hazardous dust which
may require special breathing equipment. Check before using the tool.
Even if the machine has a low noise level the actual polishing process
may cause a noise level such that ear protectors will be required. If there
are sharp areas on the material being sanded safety gloves are
recommended.
Do not use undersized or oversized polishing accessories.
Safety Rules for a Polisher
1) Read all the instructions before using this tool. All operators must be
fully trained in its use and aware of these safety rules.
2) Do not exceed the maximum working air pressure.
3) Use personal safety equipment.
4) Use only compressed air at the recommended conditions.
5) If the tool appears to malfunction remove from use immediately and
arrange for service and repair.
6) If the tool is used with a balancer or other support device ensure that
it is fixed securely.
7) Always keep hands away from the working attachment fitted to the
tool.
8) The tool is not electrically insulated. Never use the tool if there is any
chance of it coming into contact with live electricity.
9) Always when using the tool adopt a firm footing and/or position and
grip the tool firmly to be able to counteract any forces or reaction forces
that may be generated whilst using the tool.
10) Use only correct spare parts. Do not improvise or make temporary
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) Always check the speed of the attachment is higher than the speed
of the tool.
20) Check speed of tool at regular intervals.
21) Check always that the material to be polished may not cause a risk
by being sanded, i.e. fire or explosion.
22) If self fixing discs are used always ensure the disc is fixed centrally to
the pad.
23) Use only accessories (i.e. pads and discs) rated to run above the
speed of the tool.
