EQUIPMENT

The new Anti Vibration technology built into this specific model will produce unrivalled lower levels of vibration. This is achieved by using active vibration absorbers, and damper springs absorb the reaction force caused by the drill bit at the moment of impact. The level of vibration is further reduced by completely separating the machine holding section from the motor/transmission section. Therefore, when the machine moves the handle stays still, similar to how a shock absorber works on a motor vehicle. Another great new addition on the HR4013 is the soft no load function that reduces the vibration of the tool body when idling and accordingly decreases the amount of vibration to the operator’s hands. It also mini- mises the deflection of the bit tip when you begin to chip. The HR4013 has increased drilling efficiency which is 20% higher (using a 32 mm diameter bit) and a 45% higher chipping efficiency (with a bull point) when compared to its predecessor model. An SDS-Max drive system, with a drilling capacity of 40 mm will drill just about anything. The one-touch sliding chuck allows for quick and easy bit changes. Due to rotary hammers being used in rugged applications, Makita has focused on the safety aspects of both the operator and the tool. A torque limiter has been built in to ensure stable torque control that stops the rotation of the drill bit in case it hits against any reinforcing bars, The HR4013 Rotary Hammer is powered by an 1 100 Wmotor and produces super speed and efficiency during drilling, chiselling and demolition operations in reinforced concrete. > NOW WITH ADVANCED VIBRATION CONTROL

thus preventing possible muscular injuries to the operator or damage to the tool. This 2-mode rotary hammer with its easy to operate operation mode change lever that is located on the top of the motor housing has four setting options –the lock-on position for continuous chiselling applica- tions; a trigger position for intermittent chiselling applications; a bit angle setting and then of course the rotation with hammering. A soft rubberised D-grip handle and side handle provides added comfort and greater control, while minimising hand fatigue and pain. It also reduces the level of vibration absorbed by the operator. The HR4013 has a red LED service light that indicates when to replace the carbon brushes. The Makita HR4013 with its low level of vibrationwill make a substantial difference to both user and project alike, enhancing operator comfort and productivity.
