GENERAL
■ Operators should receive training from qualified
personnel.
■ Do not bend tool to free if stuck.
■ Tool should only be used to install fasteners.
■ NEVER use as a jack/spreader or hammer.
TO INSTALL A BOBTAIL FASTENER:
1. Check work and remove excessive gap. (Gap is the
space between sheets. Gap is excessive if not
enough pintail sticks through the collar for the nose
assembly puller to grab onto).
2. Put BOBTAIL pin in hole.
3. Slide BOBTAIL collar over pin. (The flanged end of the
collar must be towards the pieces being fastened.)
4. Push nose assembly onto the pin until the nose
assembly puller stops against the pin. Tool and nose
assembly must be held at right angles (90 degrees) to
the work.
5. Depress tool trigger to start installation cycle.
6. When forward motion of nose assembly anvil stops,
release trigger. Tool will go into its return stroke and
push off the installed fastener.
7. The tool and nose assembly are ready for the
next installation cycle.

WARNING: To avoid severe personal injury,
wear approved eye and ear protection.
Ensure
adequate clearance for Operator’s hands
before proceeding with fastener installation.
WARNING: Do not pull on a pin without plac-
ing fastener/collar in a workpiece. This can
cause pin to eject with great velocity and
force if pintail breaks off or teeth or grooves
strip. This may cause severe personal injury.
CAUTION: Remove excess gap from between
the sheets. This permits enough pintail to
emerge from collar for ALL puller teeth to
engage with pintail. If ALL teeth do not engage
properly, jaws will be damaged.
WARNING: To avoid pinch point, never
place hand between nose assembly and
work piece.
WARNING: Only use compatible equip-
ment with this tool.
