Vibration reduction
Makita claims that its new 32kg electric breaker, the HM1812, sets best-in-class standards with a 60% increase in impact energy at 73 joules and a 25% reduction in vibration to just 6.5m/s².
The HM1812 introduces a new vibration damping system that effectively separates the impact generation from the motor housing, cutting vibration ratings and producing 4 hours 43 minutes of useable work time to reach the Exposure Limit Value.
This breaker is powered by a 2000w 240v motor (1700w in 110v version) that gives this it a low 107 dB(A) sound power rating.
The Makita Soft-Start function is incorporated allowing maximum power to be ramped up on full depression of the trigger. This limits torque reaction to the motor to ensure that the operator keeps full control. The soft no-load function cuts motor impact if the motor is running but the point is not pressed to the ground and this too effectively reduces vibration. The operator is further protected by the soft-grip handles whilst the ‘top mounted’ heavy duty switch further limits the operators’ hand fatigue.
