EKASAND Back-Up Pads EKASAND Overhaul Service Kit
EKASAND Service Tools and Accessories
When an EKASAND OS needs to be serviced, we offer a tool kit to make the disassembly/assembly fast and easy. The Service Tools are highly recom-
mended for use with the Overhaul Service Kit. NOTICE: To receive any expressed or implied warranty, the tool must be repaired by an authorized EKASAND
Service Center.
The ESA3311 EKASAND Overhaul Service Kit contains all the re-
placement parts that naturally wear over time and a straightforward
manual to make servicing an EKASAND sander simple.
Overhauling the Orbital Sander can be made even easier with the
use of the above Service Tools. The Service Tools also reduce the
chance of improper assembly.

DOC 1114 6 04/26/06
Use a clean lubricated air supply that will give a measured air pres-
sure at the tool of 90 PSI/6.1 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 meter maximum length airline. It is recom-
mended that the tool be connected to the air supply as shown in
Figure 1. Do not connect the tool to the airline system without in-
corporating 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 lubricated
by shutting off the air supply to the tool, depressurizing the line by
pressing the lever on the tool. Disconnect the airline and put 2 to
3 drops of a suitable pneumatic motor lubricating oil, preferably in-
corporating 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 recommended that the air pressure at the tool be 90 PSI/6.1
Bar while the tool is running so the maximum RPM is not exceed-
ed. The tool can be run at lower pressures but should never be run
higher than 90 PSI/6.1 Bars. If run at lower pressure the perfor-
mance of the tool is reduced.
Proper Use of Tool
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. Se-
lect a suitable abrasive and secure it to the back-up pad.
Be careful and center the abrasive on the back-up pad.
3) 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.
4) Always remove the air supply to the sander before tting,
adjusting or removing the abrasive or back-up pad.
5) Always adopt a rm footing and/or position and be aware of
torque reaction developed by the sander.
6) Use only correct spare parts.
7) Always ensure that the material to be sanded is rmly xed
to prevent its movement.
8) Check 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 con-
nected.
9) Do not exceed maximum recommended air pressure.
10) 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 electric-
ity, gas pipes, water pipes, etc. Check the area of operation
before operation.
12) Take care to avoid entanglement with the moving parts of
the tool with clothing, ties, hair, cleaning rags, etc. If en-
tangled, it will cause the body to be pulled towards the work
and moving parts of the machine and can be very danger-
ous.
13) Keep hands clear of the spinning pad during use.
14) If the tool appears to malfunction, remove from use imme-
diately and arrange for service and repair.
15) Do not allow the tool to free speed without taking precau-
tions to protect any persons or objects from the loss of the
abrasive or pad.

This sander is designed for sanding all types of materials i.e. met-
als, wood, stone, plastics, etc. using abrasive designed for this
purpose. Do not use this sander for any other purpose than that
specied without consulting the manufacturer or the manufactur-
er’s authorized supplier.
Do not use back-up pads that have a working speed less than
10,000 OPM free speed.
Putting the Tool into Service
Work Station
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 in any position but before any such use, the operator must
be in a secure position having a rm grip and footing and be aware
that the sander can develop a torque reaction. See the section
“Operating Instructions”.
