"Auto-grease" function...Optional

Standard internal piping allows direct grease application to the front cover and the thrust-bush section, thereby improving rod and bush life. Further, detachment of the grease nipple and installation of dedicated piping, enables an automatic grease supply by remote control, either from within the cabin or with a timer system, to be used.

 
Piston idle blow prevention function.....Optional

During a long stroke, at the instant that the object to be crushed has been broken, idle blow of the piston normally occurs, but with the F-series, it is automatically eliminated. (Patented)

Number-of-blows manual adjustment function.....Standard

Stepless adjustment is possible via the adjuster. Further, spool replacement allows selection of "idle blow" and "idle blow prevention" during a long stroke. ("idle blow prevention" type fitted as standard)
 

Number-of-blows remote adjustment function.....Optional
Thanks to installation of  pilot pressure piping operator manipulation from within the cabin permits on/off selection as well as switching between low/high number-of-blows.

Safety valve function ....Standard
Should the operating pressure rise above 21~22Mpa, the "safety valve" incorporated in the hydraulic breaker automatically opens to protect the breaker from an overload. (Patent pending)

Dust intake prevention function.....Standard
Aspecially incorporated device prevents dust (such as rock dust) from being drawn into the "Front head". Incorporation of an "Air filter" and "Air check valve" in the back head and front head, eliminates the "air pump phenomenon" caused by the automatic dust prevention effect. (Patent pending) Dedicated air piping set....Optional
