Clearing a jammed nail gun:
Disconnect the tool from the air supply before performing any maintenance. Once air supply is
disconnected, pull back on the nail switch release latch. Remove any fastener(s) or nail(s) which
are in the magazine. Insert a flathead screwdriver (not included) into the driving mechanism of the
nail gun and push the driving mechanism back into the gun body. This should free the fastener/nail
jam. Remove any bent fastener or nail from the gun body or driver guide and/or nail plate. Once
bent fastener or nail is removed, reinsert the fastener(s) or nail(s) into the magazine. Close the nail
switch release latch so that there is pressure on the fastener(s)/nail(s). Reconnect the air supply
to the nail gun.
