 If possible, use a stand, spring pull/balancer or com-
pensation device in order to support the weight of the
pneumatic tool.
 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.
