Energy Recovery System: The energy recovery system increases the striking power using the energy generated by the piston return. When the hammer is used on hard materials, the energy recovery system automatically increases the stroke rate to optimize performance.

exclusive distributor System: The patented valve controls the piston movement to maximize firepower.

Piston, high quality cylinder: The piston and cylinder are made of the same steel high quality as that used in the European aerospace industry. The number of wearing parts such as piston and cylinder has been reduced to lower the cost of replacement and maintenance. The tight tolerances minimize internal leaks and increase the efficiency of the hammer.

Protection against bumps White: A hydraulic damping limit switch in the bottom of the cylinder slows then stops the downward movement of the piston. This damping system prevents the first strike is carried out "blank".
