The nitrogen chamber provides significant reduction in breaker recoil. The low-pressure nitrogen charge cushions piston recoil to protect the skid steer and operator from the recoil caused during the ''rebound'' or ''cocking'' stroke. The efficient, fully hydraulic design protects the skid steer hydraulic circuit so that no surge-damping accumulators are required. Breakers offer a powerful punch and dependable performance with only two moving parts. With few seals and no special tools required for repair, these breakers are truly field serviceable and owner repairable. For tight trench work or crowded demolition applications, the narrow rectangular shape lets the operator get into tough spots where other breakers can't reach. The precision-ground and plated components of the breakers offer high efficiency and light weight.
