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.
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.

Safety and operating instructions
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.
) Minimize exposure to reaction forces.

• When cutting:
A cut-off wheel can get stuck if the wheel is
either bent or if it is not guided properly. Make
sure to use correct flanges for cut-off wheels
and avoid bending the wheel during cut-off
operation.
• When drilling:
The drill might stall when the drill bit breaks
through. Makes sure you use support handles
if the stall torque is too high. The safety stand-
ard ISO11148 part 3 recommends to use
something to absorb the reaction torque above
10 Nm for pistol grip tools and 4 Nm for
straight tools.
• When using direct driven screw or nutrunners:
Reaction forces depend on tool setting and joint
characteristics. The ability to bear reaction
forces depends on the operator's strength and
posture. Adapt the torque setting to the operat-
or's strength and posture and use a torque arm
or reaction bar if the torque is too high.
