Choosing between modes allows you to optimally adapt the device to your needs. The polisher is also characterized by high efficiency long runtime and a compact design. This is achieved thanks to the use of a brushless motor. The dpo500z model also features numerous features that increase comfort and safety of use. These include: an anti-restart function soft start continuous operation a switch lock and a side handle. In addition the makita polisher has been designed to limit the contact of the battery with the bodywork as much as possible and the rubber-coated gear housing does not scratch the paintwork when the tool is placed with the disc up on the work surface.product features:4 operating modes: forced oscillation and inertial oscillation (set using the side knob) standard mode and finishing mode (set using the button on the top of the housing)brushless technology - increased efficiency longer runtime and a smaller tool designxpt technology - increased resistance to dust and moistureelastomer-coated gear housing cover - protection against scratching the paintwork when the polisher is placed with the disc up on the paintbattery located in a place that limits contact with the bodyworkanti-restart function prevents the device from starting spontaneouslysoft start protects against the so-called kickback effect when startingspeed control using the setting knob and the switch trigger allows you to optimize your work pace2 switch locks: one for continuous operation (the ability to work without holding the trigger) and the other to protect against accidental startingpossibility to attach a side handle for more convenient tool maneuveringdust covers prevent filings from entering the interior of the deviceexample operating time: up to approx. 35 minutes of operation on a single charge of the bl1860b battery in finishing modepowered by 18v makita lithium-ion batteries except batteries without electronics (bl1811g bl1813g bl1815g) and the bl1815 battery (18v 1.3ah)anti-vibration side handle 144163-3sanding plate 125mm (with velcro) 197922-4allen key 5 783203-8**model without battery and charger
