Removal Wear safety glasses and steel-tipped safety shoes to avoid possible injury while handling equipment. Level cannon before venting nitrogen to avoid serious injury to personnel or damage to equip- ment caused by cannon assembly sliding out of battery. Keep all parts of body clear to prevent serious injury when venting nitrogen. High pressure nitro- gen must be completely vented before the drain plug is loosened to prevent serious injury caused by escaping hydraulic fluid. Ensure valves are closed prior to disassembly to prevent sudden release of nitrogen pressure. Care should be taken to prevent contamination of recuperator cylinder during disassembly and assembly. Prior to removing valve cap ensure that the pneumatic valve is closed to prevent release of ni- trogen pressure. This will prevent serious injury or damage to equipment caused by sudden release of nitrogen pressure. 5-54 Change 2
