4) The throttle control valve is depressed to begin the
flow of compressed air to the piston. The piston will
begin to strike the accessory tool and provide energy

frequency rates and blow force values. Normal
operation of the Long Reach Air Tool is with the throttle
control valve in its maximum depressed position.
