Clearing a Jammed Fastener
Most jams are caused by a fastener or part of
a fastener wedging between the driver blade
and the nail guide. Fastener strips with an
incorrect collation angle or the wrong fas-
tener type may cause continuous jamming.
To clear the jam:
1. Lay the tool on its side and point the
nose of the tool away from yourself and
others.
2. Disconnect the air supply from the tool
and remove fastener strip.
3. Pull out the latch tab to open the jam-
clearing door.
4. Remove any debris.
5. If the driver blade is visible, insert a
screwdriver into the jam clearing door.
The tip of the screwdriver should contact
the tip of the driver blade.
6. Tap the screwdriver gently with a ham-
mer. The screwdriver will push the driver
blade back, freeing the jam.
7. Remove the fastener and other debris
(use needle-nose pliers if necessary).
8. Close the jam-clearing door securely.
9. Follow the steps under "Required Daily
Testing" before restarting the work.

Do not carry an air hose or a tool con-
nected to an air hose when climbing
ladders, rigging or scaffolding. Do
