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 backung pads that have a working
speed less than 8,500 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 and have 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 service and repair 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 backung pad. Take care to center the
abrasive on the backung pad.
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 disconnect the air supply from the tool before fit-
ting, adjusting or removing the abrasive or backung pad.
6( Always adopt a firm footing and/or position and be aware
of the torque reaction developed by the tool.
7) Use only correct spare parts.
8( Always ensure that the material to be sanded is firmly
fixed to prevent its movement.
9( Check the 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( Do not exceed the maximum recommended air pressure.
Use safety equipment as recommended.
11( 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 operation.
12( 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, which can be very dangerous.
13( Keep hands clear of the spinning pad during use.
14( If the tool appears to malfunction, remove from use immediately and arrange for service and
repair.
15( 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(.
