Proper Use of Tool
This tool is designed for sanding all types of materials i.e. metals,
wood, stone, plastics, etc. using abrasive designed for this pur-
pose. Do not use this tool for any other purpose than that speci-
fied without consulting the manufacturer or the manufacturer's
authorized supplier. Do not use backing pads that have a working
speed less than 12,000 rpm 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 having a firm grip and
footing and be aware that the tool 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 backing pad. Take care to centre the abrasive on the backing
pad.
3) Always wear appropriate 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 stop-
ping. 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 backing 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 collec-
tion bag should be cleaned or replaced daily or when bag
reaches half full or 2.3 kg (5 lbs.). Cleaning or replacing the
bag also assures optimum performance.
11) Do not exceed maximum recommended air pressure. 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 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, 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 per-
sons 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 tool to the air supply
and run 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).
