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.
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.
