WARNING:
PUT THE SAFETY DEVICES AND THE WARNING NOTICES IN POSITION BEFORE YOU START A TASK ON OR NEAR:
- THE FLIGHT CONTROLS
- THE FLIGHT CONTROL SURFACES
- THE LANDING GEAR AND THE RELATED DOORS
- COMPONENTS THAT MOVE.
WARNING:
THE CARTRIDGE IS AN EXPLOSIVE DEVICE. REMOVE IT BEFORE YOU DISASSEMBLE THE FIRE EXTINGUISHER BOTTLE.
TO PREVENT INJURY TO THE PERSONNEL BECAUSE OF THE EXPLOSION OF THE CARTRIDGE IF IT HAS NOT BEEN FIRED:
- INSTALL A SHUNT DEVICE.
- THIS WILL SHUNT THE PINS TOGETHER ON THE CARTRIDGE BEFORE ITS REMOVAL.
WARNING:
BE VERY CAREFUL WHEN YOU MOVE A FULL FIRE EXTINGUISHER BOTTLE. A SUDDEN OR HEAVY SHOCK TO A FULL BOTTLE CAN CAUSE UNWANTED DISCHARGE AND INJURY TO PERSONS.
