Maintenance
Lubricants
All gears and rotating parts shall be greased with
LUBRA K HS (Ordering No. 4230 1480 00). In
the US, the same lubricant is known as Courier.
(Data sheet and other details can be ordered from
Atlas Copco Industrial Technique AB.
Under normal conditions, with motor temperatures
below 80C, a life cycle of 4 years or 2 million cy-
cles is expected.
If a different lubricant is being used a service inter-
val of less than 2 years, or 1million cycles is more
likely.
To ensure maximum life length of the equipment,
make sure to service all mechanical parts once a
year by authorized service staff. Make sure to cali-
brate Torque transducers at regular intervals ac-
cording to your internal quality regulations, but at
least once a year.
Overhaul
Service must only be carried out by qualified per-
sonnel who have access to the Service instruction
and/or have been trained for service on QST nu-
trunners.
The electric motor is a sealed unit and may under
no circumstances be opened by anyone else than
Atlas Copco Industrial Technique AB!
If the electric motor is defect or in need of service,
the complete motor unit should be returned to At-
las Copco for exchange.
Motors which have been opened by anyone else
than Atlas Copco Industrial Technique AB will not
be serviced.

Ergonomic guidelines
Consider your workstation as you read through this
list of general ergonomic guidelines and see if you
can identify areas for improvement in posture,
component placement, or work environment.

• Take frequent breaks and change work posi-
tions frequently.
• Adapt the workstation area to your needs and
the work task.
• Adjust for convenient reach range by deter-
mining where parts or tools should be lo-
cated to avoid static load.
• Use workstation equipment such as tables
and chairs appropriate for the work task.
• Avoid work positions above shoulder level or
with 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, par-
ticularly for operations requiring a degree
of force.
• Adjust for convenient field of vision by mini-
mizing movement of the eyes and head during
the work task.
• Use the appropriate lighting for the work task.
• Select the appropriate tool for the work task.
• Use ear protection equipment in noisy environ-
ments.
• Use high-quality inserted tools or consumables
to minimize exposure to excessive levels of vi-
bration.
• 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 the 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 standard ISO11148 part 3 recom-
mends using something to absorb the reac-
tion torque above 10 Nm for pistol grip
tools and 4 Nm for straight tools.
