Proper Use of Tool
Figure 1
This tool is designed for use on 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-
ed without consulting the manufacturer or the manufacturer’s
authorized supplier. Do not use backing pads that have a working
speed less than 3,000 rpm free speed.
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 oor. It can be used in any position but before any such use,
the operator must be in a secure position and have a rm grip and
footing, and be aware that the tool can develop a torque reaction.
See the section “Operating Instructions”.
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 lter,
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(.
1( Read all instructions before using this tool. All operators must be fully trained in its use
and be 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 center the abrasive on the backing
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 tool before
tting, adjusting or removing the abrasive or backing pad.
6( Always adopt a rm 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 rmly
xed to prevent its movement.
9( Check the hose and ttings 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 servicing
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.

Specications subject to change without prior notice.
*The values stated in the table are from laboratory testing in conformity with stated codes and standards, and are not sufcient for risk
evaluation. Values measured in a particular work place may be higher than the declared values. The actual exposure values and amount
of risk or harm experienced by an individual are unique to each situation and depend upon the surrounding environment, the way in which
the individual works, the particular material being worked, work station design as well as upon the exposure time and the physical condi-
tion of the user. Mirka Ltd. cannot be held responsible for the consequences of using declared values instead of actual exposure values
for any individual risk assessment.
