> Small size Hydraulic Breakers F1 to F5

Hydraulic Direct-Acting System contributes to reduced maintenance costs!
No back head gas charging for ease of maintenance. Through bolt design with large CD threads for added strength.
Increase front head wall thickness for added serive life.

> Medium size Hydraulic Breakers F6-F9

Hydraulic Direct-Acting System contributes to reduced maintenance costs!
Increase in back head pressure and large piston diameter results in 25% greater impact energy.Longer thrust bushing improves piston alignment during impact and incorporates grease holes to evenly distribute grease in the front head.Through bolt design with large CD threads for added strength. Increase front head wall thickness for added service life.

> Large size Hydraulic Breakers

Large size F series models responding to next generation needs by offering new functions and greater versavility!
Advanced technology supporting new function Patented dust intake prevention system.Improved lubrication greease front head and thrust bushing.Higher back head pressure results in a 20% increase in impact energy over previous models.Free spinning front head bushing ensure uniform wear. Built-in hydraulic safety valve actuates when it exceeds the maximum pressure.
