Clearing a Jammed Nail (Fig. A, L)

WARNING: To reduce the risk of serious personal injury, disconnect battery pack
from tool before making any adjustments, changing accessories, servicing,
or moving the tool. Such preventative safety measures reduce the risk of starting the
toolaccidentally.

CAUTION: When removing a jammed nail, DO NOT orient the nailer with the nose
up or with the battery foot up. Positioning the nailer this way makes the jammed nail or
pieces of the nail more likely to be ingested into the nailer. If any portion of a nail is ingested
into the tool, the nail should be retrieved by removing the topcap.
If a nail becomes jammed in the nosepiece, keep the tool pointed away from you and follow
these instructions to clear:
1. Remove battery pack from tool and engage

the blade with a long screw driver may benecessary.
