Reassemble the nailer in the reverse order of disassembly, making sure all parts are correctly aligned and attached. Use your notes from step 3 to guide you.

Step 8: Test the Nailer

Before loading it with nails, connect the nailer to the air supply and fire it a few times to ensure it’s functioning correctly. If everything is in order, you’re ready to start roofing!

Step 9: Reload Nails

Fill the nail magazine with your chosen roofing nails.
