Through Bolt	Assemble & hold the front head, cylinder and back head tightly. They need to be inspected for loosening and re-tightened weekly according to specified torque. Quality and tightness of Through Bolt is very important to ensure the durability of the breaker.
Back Head	Contains the cushion chamber charged with Nitrogen(N2) gas that compresses during upward strokes of the piston, and serves to provide maximum absorption of piston recoil, efficientiy storing this energy for the next blow.
Control valve	The valve controls reciprocal piston action with hydraulic fluid distribution.
Cylinder	Contains the moving piston which strikes the tool. The seals for both ends of the Piston are also located in the Cylinder. The seals for the upper end of the piston are located in a removable Seal Retainer while the seals for the lower end of the piston are located in grooves machined directly into the cylinder.
Accumulator	Reduces the surge pressure and spikes generated from the circiut of excavator. It also increases impact energy. (Applied for PB1500 and bigger models.)
Piston	Designed to deliver maximum energy to the Tool and efficiently reduce recoil from the Tool. Impact power of breaker is decided by the amount of energy delivered by Piston.
Front head	Retains the tool using the tool pins. The tool can be replaced by removing these pins.
Tool	Transfers piston impact power to the objects. We recommend various types of tool according to working conditions.
