LOADING THE TOOL WITH NAILS
-Remove the battery pack into the tool.
-With the nose of the tool pointed away from you, feed a strip of nails into the magazine. Be sure the nails are pointed downward and at the angle shown.
Keep the tool pointed away from yourself and others when loading nails. Failure to do so could result in possible serious personal injury.
-Slide the nail strip as far forward in the magazine as possible.
-Slide the pusher all the way to the rear of the magazine. Release the pusher and allow it to push the nails up to the driving mechanism. The pusher will stop when it rests against the end of the nail strip.
NOTE: Do not allow the pusher to snap back into place.
Use only the nails recommended for use with this tool. The use of any other nails can result in tool malfunction, leading to serious injuries.
Never load nails with the work piece contact or trigger activated. Doing so could result in possible serious personal injury.
