Adjustment of restrictor valve
The restrictor valve is used for restricting the maxim-
um speed as well as for shutting off the air supply
before changing paper.
With dust extraction
At delivery the sander is equipped for using self
suction dust extraction. Connect a vacuum hose to
the connector sleeve.
Adjustment of dust extraction power – If neces-
sary the dust extraction power can be reduced using
the spacer. The spacer is to be located between the
ball bearing and the pad.
Without dust extraction
If the sander is to be used as a non-vacuum model
proceed as follows:
• Press the plug into the motor casing.
• Press the exhaust diffusor, including the silencer,
onto the connector sleeve.
Maintenance
Rust protection and internal cleaning
Water in the compressed air, dust and wear particles
cause rust and sticking of vanes, valves etc.
This can be solved by lubricating with oil (a few
drops), running the machine for 5-10 seconds and
wiping off excess oil with a cloth. Do this before
longer standstills.
Lubricating guide
Use lubricants of good quality. The oils and greases
listed in the lubrication table are examples of lubric-
ants that can be recommended.

Overhaul
The machine should be dismantled, overhauled and
cleaned after roughly 500 hours of operation, but at
least once every six months. If the machine is not
running properly, it should be taken out of service
for inspection.

Safety and operating instructions
Check the condition of the bearings, the wear of
the vanes and their surfaces condition. Check that
the original vanes travel freely in the rotor slots.
Clean the rotor and the cylinder before assembling
the vanes. Apply a thin layer of grease on to the end
faces of rotor or end plates.
Assemble the motor dry and check that it is run-
ning free. Add two drops of oil through the air inlet
and turn the motor over so that oil is distributed over
the internal motor parts. Run the machine and expel
excess exhaust oil in an absorbing place.
The strainer in the air inlet adapter should be
cleaned frequently in order to prevent clogging,
which decreases the capacity.

Ergonomic guidelines
) Take frequent breaks and change work positions
1
frequently.
) Adapt the workstation area to your needs and the
2
work task.
• Adjust for convenient reach range by determin-
ing where parts or tools should be located to
avoid static motion.
• Use workstation equipment such as tables and
chairs appropriate for the work task.
) Avoid work positions above shoulder level or with
3
static holding during assembly operations.
• When working above shoulder level, reduce
the load on the static muscles by reducing the
weight of the tool, using for example torque
arms, hose reels or weight balancers. You can
also reduce the load on the static muscles by
holding the tool close to the body.
• Make sure to take frequent breaks.
• Avoid extreme arm or wrist postures, particu-
larly for operations requiring a degree of force.
) Adjust for convenient field of vision by minimiz-
4
ing movement of the eyes and head during the
work task.
) Use the appropriate lighting for the work task.
5
) Select the appropriate tool for the work task.
6
) Use ear protection equipment in noisy environ-
7
ments.
) Use high-quality inserted tools or consumables to
8
minimize exposure to excessive levels of vibra-
tions.
