TOOL OPERATION
Daily Function Test
Always check the tool first to make
sure that it does not contain a load
or fastener. Test the tool several times
by depressing the muzzle bushing fully
on a hard surface and pulling the trigger.
You should hear an audible click as the
firing pin releases. Let up on the tool and
check to be sure that the barrel has
opened to the semi-closed position.

WITH THE POINT OUT
OPERATING THE MODEL 721
1. After checking to be sure that
the tool is not loaded, point it in a
safe direction and snap the barrel
open with a quick downward
motion.This action positions the
piston in preparation for the next
fastening. Use the spall guard every
time possible to minimize the risk of
being struck by flying debris.
2. With finger off the trigger, place
the fastener, point out, into the
muzzle end of the tool until the
point end is inside the muzzle.
NEVER load a fastener with
your finger on the trigger. DO
NOT use excessive force when
inserting a fastener. STOP
immediately if excessive force is
required, inspect the barrel to
find out why the fastener is not
entering the muzzle freely. DO
NOT continue loading unless
the problem is corrected.
3. With the tool pointed in a safe
direction, the barrel fully open, and
your finger away from the trigger,
make sure the chamber is clear
and insert a load into the tool
chamber. Always start with the #1,
gray power level. If the #1 load does
not fully set the fastener, try the
next higher power level until the
proper power level is found.
