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.
Lubrication
The front motor ball bearing should be lubricated
with grease in conjuction with the regular overhaul
of the machine.
For flexible spindle extension – When fitting the
extended spindle – apply 0.5 cm
"Lubricating Engineers LE3752" (or EP grease) at
the bottom of the hole in the collet holder.
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.

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.
