Page 4: Selling Point Descriptions
4-1-2. Original design vibration-absorbing handle (Vibration-absorption is significantly improved) Hitachi's original design vibration-absorbing handle minimizes vibration through the rolling and compression of four cylindrical rubber cushions on inclined surfaces. The spring constant factor is as low as that of the Models H 41SA, H 45SB2, H 41SC, H 45MA, H 60MA and H 60MB and the cushioning structure greatly reduces vibration. -

Page 9: Reference Information
8. REFERENCE INFORMATION Structure: Piston Crank cover O-rings Crank shaft Connecting rod Striker Second hammer Air chamber Cylinder Armature Fig. 3 8-1. Striking Operation The rotation of the armature is transferred to the crank shaft and connecting rod, which in turn cause the piston to reciprocate inside the cylinder. -
Page 10: Idling-Proof Mechanism
8-2. Idling-Proof Mechanism When the bull point is released from the concrete surface, the second hammer moves to the position illustrated in Fig. 4, and the striker moves out of striking position. When this occurs, the air holes are opened and the pressure within the air chamber remains unchanged even though the piston continues to reciprocate, thereby preventing striking operation. -
Page 11: Vibration Absorbing Construction
8-4. Vibration Absorbing Construction Hitachi original, innovative units which absorb vibration are installed between the switch handle and the crank case and between the switch handle and the housing. As a result, the amount of vibration transmitted from the main body to the arms of the operator is considerably less in comparison with conventional hammers. -
