Proper Use of Tool
This sander is designed for sanding all types of materials i.e.
metals, wood, stone, plastics, etc. using abrasive designed for this
purpose. Do not use this sander for any other purpose than that
specified without consulting the manufacturer or the manufac-
turer's authorized supplier. Do not use back-up pads that have a
working speed less than 10,000 OPM free speed.

Work Stations

The tool is intended to be operated as a hand-held tool. It is
always recommended that the tool be used when standing on a
solid floor. It can be used in any position but before any such use,
the operator must be in a secure position and have a firm grip
and footing, and be aware that the sander can develop a torque
reaction. See the section "Operating Instructions".
1) Read all instructions before using this tool. All operators must be fully trained in its
use and aware of these safety rules. All servicing and repairs must be carried out by
trained personnel.
2) Make sure the tool is disconnected from the air supply. Select a suitable abrasive and
secure it to the back-up pad. Be careful and center the abrasive on the back-up pad.
3) Always wear the 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 disconnect the air supply from the sander
before fitting, adjusting or removing the abrasive or
back-up pad.
6) Always adopt a firm footing and/or position and
be aware of the torque reaction developed by the
sander.
7) Use only correct spare parts.
8) Always ensure that the material to be sanded is firmly
fixed to prevent its movement.
9) Check hose and fittings regularly for wear. Do 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. The vacuum dust
collection bag should be cleaned or replaced daily.
Cleaning or replacing of the bag also assures opti-
mum performance.
11) Do not exceed the 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 working area before use.
13) Take care to avoid entanglement of 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, stop using it immediately and arrange for servicing
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.
Use a clean lubricated air supply that will give a measured air
pressure at the tool of 6.2 bar (90 psig) bar when the tool is run-
ning with the lever fully depressed. It is recommended to use an
approved 10 mm (3/8 in.) x 8 m (25 ft) 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 recommended that an air filter,
regulator and lubricator (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.
To manually lubricate the tool, disconnect the airline and put 2 to
3 drops of suitable pneumatic motor lubricating oil such as Fuji
Kosan FK-20, Mobil ALMO 525 or Shell TORCULA® 32 into the
hose end (inlet) of the machine. Reconnect the tool to the air
supply and run the tool slowly for a few seconds to allow air to
circulate the oil. If the tool is used frequently, lubricate it on a daily
basis or lubricate it if the tool starts to slow or lose power.
It is recommended that the air pressure at the tool is 6.2 bar (90
psig) while the tool is running. The tool can run at lower pressures
but never higher than 6.2 bar (90 psig).
