Putting the Tool into Service
Operating Instructions
1) Read all instructions before using this tool. All opera-
tors must be fully trained in its use and aware of
these safety rules. All service and repair must be
carried out by trained personnel.
2) Make sure the tool is disconnected from the air sup-
ply. Select a suitable abrasive and secure it to the
back-up pad. Be careful and center the abrasive on
the back-up pad.
The tool is intended to be operated as a hand held tool.
It is always recommended that the tool be used when
before any such use, the operator must be in a secure
the sander can develop a torque reaction. See the sec-
tion “Operating Instructions”.
Use a clean lubricated air supply that will give a mea-
sured air pressure at the tool of 90 psig (6.2 bar) when
the tool is running with the lever fully depressed. It is
recommended to use an approved 3/8 in. (10 mm) x
25 ft (8 m) maximum length airline. It is recommended
that the tool be connected to the air supply as shown in
Figure 1.
Do not connect the tool to the airline system without
incorporating an easy to reach and operate air shut off
valve. The air supply should be lubricated. It is strongly
(FRL) be used as shown in 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 manually lubricated by shutting off the air sup-
ply to the tool, depressurizing the line by pressing the
lever on the tool. Disconnecting the airline and putting
2 to 3 drops of suitable pneumatic motor lubricating oil,
preferably incorporating a rust inhibitor into the hose end
(inlet) of the machine. 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 recommend-
ed that the air pressure at the tool be 90 PSI (6.2 Bar)
while the tool is running so the maximum RPM is not
exceeded. The tool can be run at lower pressures but
should never be run higher than 90 PSI (6.2 Bar). If run
at lower pressure the performance of the tool is reduced.
3) Always wear required safety equipment when using
this tool.
4) When sanding always place the tool on the work
then start the tool. Always remove the tool from the
work before stopping. This will prevent gouging of
the work due to excess speed of the abrasive.
5) Always remove the air supply to the sander before
pad.
6)
aware of torque reaction developed by the sander.
7) Use only correct spare parts.
8) Always ensure that the material to be sanded is
9)
not carry the tool by its hose; always be careful to
prevent the tool from being started when carrying
the tool with the air supply connected.
10) Dust can be highly combustible. Vacuum dust col
lection bag should be cleaned or replaced daily.
Cleaning or replacing of bag also assures optimum
performance.
11) Do not exceed maximum recommended air pres-
sure. Use safety equipment as recommended.
12) The tool is not electrically insulated. Do not use
where there is a possibility of coming into contact
with live electricity, gas pipes, water pipes, etc.
Check the area of operation before operation.
13) Take care to avoid entanglement with the moving
parts of the tool with clothing, ties, hair, cleaning
rags, etc. If entangled, it will cause the body to be
pulled towards the work and moving parts of the
machine and can be very dangerous.
14) Keep hands clear of the spinning pad during use.
15) If the tool appears to malfunction, remove from use
immediately and arrange for service and repair.
16) Do not allow the tool to free speed without taking
precautions to protect any persons or objects from
the loss of the abrasive or pad.
Proper Use of the Tool
This sander is designed for sanding all types of materi-
als i.e. metals, wood, stone, plastics, etc. using abrasive
designed for this purpose. Do not use this sander for any
manufacturer or the manufacturer’s authorized supplier.
Do not use back-up pads that have a working speed less
than 12,000 RPM free speed
