Description

ABSTRACT:
A nailing machine includes a body, a driver extending downwardly from the body and vertically reciprocally movable for driving nails, and a driver guide for guiding the driver. A contact arm is movable between a lower first position and an upper second position and has a lower end for abutment on a work. A magazine is mounted on the body for feeding the nails into the driver guide. A trigger is operable by an operator for driving the driver. A trigger control device is interlocked between the trigger and the contact arm for permitting the driver to be driven by the operation of the trigger only when the contact arm is positioned in the upper second position. An idle driving prevention device is operable independently of the trigger control device for preventing the driver from being driven through operation of the trigger when the amount of the nails has been reduced to a predetermined amount.
