4-1. Selling Point Descriptions
4-1-1. A highly reliable mechanism for prevention of idle hammering results in prolonged service life
Conventional mechanism for prevention of idle hammering is to open and close the air holes according to the
movement of the striker. The Model H 30PV has air holes located at the position unaffected by the rebound of the
striker at no load. The air holes are opened and closed by the movement of the sleeve provided around the
cylinder that interlocks with the tool and the second hammer to prevent idle hammering. This mechanism
securely prevents idle hammering even in wall hammering works or even if a tool that can cause great rebound on
the striker such as a cutter is used. Thanks to the highly reliable mechanism for prevention of idle hammering, the
service life of the Model H 30PV is prolonged and hammering works requiring much attention not to break the
surroundings can be efficiently performed with the Model H 30PV.
4-1-2. Easy-to-handle tool holder specially designed for single-step installation of the hammer bit
The commercially available SDS-plus shank bits can be used in the Model H 30PV. Thanks to the single-step tool
retainer provided for the Model H 30PV, the SDS-plus shank bits can be installed just by adjusting the groove
position and pushing in.
4-1-3. Simple turning method, variable lock mechanism for easy working-angle adjustment of chisels, etc.
The tool swivel angle can be changed in 12 steps by turning the grip 60 degrees. The tool is securely locked at
the changed step by turning the grip back to the original position.
4-1-4. Soft-touch grip for easier handling
The double-layer molded handle consists of a plastic resin base covered with a soft plastic layer to ensure a soft
touch and firm, non-slip grip of the handles.
