Operation
The AEROPRO Air-powered Coiled Roofing Nailer CN45RA is equipped with a push lever at the nailing
point and
will not operate unless the push lever is depressed (pushed upwards).
Bump fire(multiple shots)
• Pull the trigger with the nailer off the workpiece.
• Drive a nail by pressing the nailer against the workpiece to
depress the push lever.
• Drive additional nails by moving the nailer along the workpiece with
a bouncing motion.Each depression of the push lever will drive a nail.
When the required nails have been driven, remove finger from the trigger(Fig.E).
Adjusting The Nailing Depth
To assure that each nail penetrates to the same depth,be sure that:
①The air pressure to the Nailer remains constant (regulator is installed
and working properly)
②The nailer is always held firmly against the workpiece.If nails are driven
too deep or too shallow into the
workpiece,adjust the nailing depth using the following instructions.
1. Disconnect air hose from nailer(Fig.F).
2.
If the nails are driven too deep,
pull the adjuster downward
and turn counter-clockwise(Fig.G)
If nails are driven too shallow,
pull the adjuster downward
and turn clockwise(Fig.H)
When the adjuster is released it will spring back up and can be set with a click at each 1/4 rotation.The
adjuster changes the nailing depth approximately 0.25 mm per 1/4 rotation.
3.Connect the air hose and perform a nailing test,ALWAYS WEAR EYE PROTECTION.
4.If additional adjustments are necessary,DISCONNECT AIR HOSE FROM NAILER and repeat step 2
