Safety instructions
Warning
• Make sure you are familiar with the operating in-
structions before you use this machine.
• Before making any adjustments (e.g. setting the
torque, changing bits or sockets) disconnect the
machine from the compressed air line.
• The machine, together with any attachments and
accessories, must never be used for anything other
than the designed purpose.
• Use power sockets only. For safe and economic
use - replace worn sockets.
• Check that the power socket is properly fastened
- replace the square drive retainer when necessary.
• Keep your fingers away from the power socket
during operation to avoid injury. Always work
with protective goggles.
• Avoid unnecessary idling, i.e. running the machine
unloaded (free speed).
• When using a suspension yoke, check that it is in
good condition and correctly fastened.
General information
General
The machine is designed for a working pressure (e)
of 6.3 - 7 bar (max.) = 630 - 700 kPa (90 - 102 psi).
If the compressed air line pressure is higher than
7 bar it is preferable reduced with a pressure regulat-
or of the type Atlas Copco REG.
The Atlas Copco Air Line Test equipment is suit-
able for checking of air pressure and airflow at the
installation point (please see AirLine Accessories in
our main catalogue).
The machine can operate at a lower working
pressure. Maximum torque will be reduced at lower
pressures.
A
If frequent used for tightening or loosening
that need longer time than 3-5 seconds, a
larger wrench should be used. Otherwise the
servicelife of the impact mechanism will be
reduced.
To avoid pressure drop use recommended hosesize,
length, and connections. For more information please

Please make sure that the impact screwdriver
is only used for its intended purposes. In the
event of inappropriate use, impact sparks
can occur between the socket wrench and
the screw or nut to be tightened. It is there-
fore recommended that torque wrenches are
used exclusively. Before using the impact
screwdriver, please make sure that this tool
is not worn and that a perfectly tight-fitting
connection is assured between the screw-
driver and the screw or nut to be tightened.
Furthermore, it must also be assured that
there is a perfect tight-fitting connection
between the square drive pin of the screw-
driver and the square retainer of the torque
wrench. Furthermore, the impact screwdriver
must be earthed to the equipotential bonding
system of the workshop, for instance through
suitable accessories such as hoses and air-
pressure connections.
To avoid excessive increases in temperature,
the operator must ensure that the working
pressure does not exceed 6.3 bar. The impact
screwdriver may only be used for fitting and
dismantling work within the range of normal
screw cycles. It is not permitted to use the
screwdriver in constant operation (e.g. in-
stead of a compressed air motor).
National safety regulations must be properly
observed, if the tool is to be used in areas
that are subject to an explosion hazard. It is
the responsibility of the user to make sure
that all possible accessories for the tool,
such as wrenches and air connections, con-
form to the national safety regulations for
equipment used in potentially explosive
areas.
A
Maintenance and repairs of the tool must be
carried out exclusively by authorised person-
nel, after which a no-load test of at least 10
minutes and temperature measurements
must be carried out and recorded in a report.
A maximum surface temperature of 135°C
may not be exceeded.
