Mechanical rather than gas operation offers low running costs and consistent performance, even at low temperatures. Fitted with a brushless motor that offers increased runtime and durability. Trigger and contact trip lock-off prevent accidental discharge of fastener. With tool free stall/jam clearance to minimise down time. The depth of drive can be easily adjusted using the thumb wheel depth adjuster. Two modes of operation: Sequential mode allows for precision placement, Bump operating mode provides the user with production speed of up to 4 nails per second.
