 Hold the pneumatic tool with a not too firm yet secure
grip, compliant with the required hand-reaction forces.
The vibrations can be intensified the firmer you hold the
tool.
 When universal rotary couplings (bayonet couplings)
are being used, retaining pins are required. Use Whip-
check hose restraints to protect against failed hose
connections or the connection between hose and pneu-
matic tool.
 Never carry the pneumatic tool by the hose.
 Support the screwdriver with, for example, a reaction
bar when you are working at high torque. Work at high
torques may result in damaging reaction torques, which
can be reduced by using a support device.
 If you want to operate the pneumatic tool in a suspen-
sion device or a clamping fixture, take care to fasten it
in the device/fixture first before connecting it to the air
supply. This measure prevents accidental starting of oper-
ation.
