Safety Information
If it is judged that the electric motor is defect or in
need of service, the complete motor unit should be
returned to Atlas Copco Tools for exchange.
Motors which have been opened by anyone else
than Atlas Copco Tools will not be serviced.
Overhaul and preventive maintenance is recom-
mended at regular intervals once per year or after
maximum 250.000 tightening depending on which
occurs sooner. If the machine is used in heavy-
duty operations more frequent overhaul may be
needed. If the machine not is working properly, it
should immediately be taken away for inspection.
When dismantling the tool always use the spe-
cially designed service tool 4080 0848 80, (two
service tools are required).

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.
• When using direct-driven screw or nutrun-
ners:
Reaction forces depend on tool setting and
joint characteristics. The ability to bear re-
action forces depends on the operator's
strength and posture. Adapt the torque set-
ting to the operator's strength and posture
and use a torque arm or reaction bar if the
torque is too high.
• Use dust extraction system or mouth protection
mask in dusty environments.
