Makita 6836 Manual

Continuous Rating (W)
Voltage (V)
Model 6836 has been developed as an upgraded sister tool to the current 6833.
Features high rotational speed of 6,000rpm for high operation efficiency while
less pressure is required on the tool to drive screws, reducing operator fatigue.
These two main advantages will allow operator to set more screws for one day
operation with less fatigue.
