4-1. Selling Point Descriptions

4-1-1. Highest chipping and demolishing performance in its class
The powerful impact force of each blow ensures efficient and easy demolition of concrete. The demolition
performance is 1.0 --- 1.3 times more powerful than that of similar products.

4-1-2. T-shaped handle with shock absorber reduces operator fatigue
The T-shaped handle is equipped with the Hitachi's original shock absorber. Vibration transmitted from the tool
main body is effectively absorbed and vibration transmitted to handle (B) and the side handle is minimized by
compressing and shearing the two blocks of rubber mounted between the housing and handle (B) and between
the housing and the side handle. The T-shaped handle improves downward chipping and demolishing
performance and reduces operator's fatigue for a long-time operation.
4-1-3. Dustproof double air vent construction protects against concrete chips
A fine mesh is mounted between the tail cover and the housing which act as the air vent (inlet) for the motor
cooling fan. The double air vent construction prevents concrete chips from entering in the motor directly (Fig. 1).
