254 and 254OS Pneudraulic Installation Tools (HK1172)
TO INSTALL A LOCKBOLT FASTENER:
1.
Place a pin in the workpiece and place the collar over
the pin.
NOTE
:
If collar has one tapered end, that end must
be out toward tool; not next to the sheet.
2.
Hold the pin
in the hole
and push the nose assembly
onto the pin protruding through the collar until the
nose anvil touches
the collar.
3. Press and hold the trigger until the collar is swaged
and the pintail breaks.
4. Release the trigger
; the tool will perform its RETURN
stroke.
The
pressure is
re-directed;
the piston moves
forward; and
the tool
is pushed off the fastener and
ready for the next
installation cycle.
TO INSTALL A HUCK BLIND FASTENER:
1. Place a
fastener in the workpiece or in the end of the
nose assembly.
NOTE
:
The tool or nose assembly must be
held against, and at a right angle (90°) to, the
workpiece.
2. Press and hold the trigger until the fastener is
installed and the
pintail breaks.
3. Release the trigger
; the tool will perform its RETURN
stroke.
The
pressure is
re-directed;
the piston moves
forward; and
the tool
is pushed off the fastener and
ready for the next
installation cycle.
CAUTIONS:
BOM blind fasteners will jam in the nose
assembly if they are pulled when not in
workpiece.
To avoid structural and tooI damage, be
sure there
is sufficient
clearance for the nose
assembly at full stroke.
CAUTION: Tool must be properly reassembled
prior to use.
Operating Instructions
FOR SAFE OPERATION, THIS SECTION MUST BE READ AND UNDERSTOOD.
Do NOT pull a
fastener with the
collar upside down.
CORRECT
CORRECT
Do NOT install a fastener without a
workpiece (structure to be fastened), a
pin, and a properly oriented collar in place.
WARNINGS:
To avoid severe personal injury, wear approved eye and ear protection.
Be sure of adequate clearance for operator’s hands before proceeding with
fastener installation.
If the tool comes with a pintail deflector or bottle, make sure it is attached to
the tool and directed away from all personnel.
Do NOT attempt to install a pin without placing the fastener and collar in the
work piece (structure to be fastened).
Do NOT attempt to install a pin without a properly oriented collar in place.
The collar flange must be against work piece.
If these safety measures are not followed, the fastener could eject with great
velocity and cause severe personal injury.
This condition can cause pin to eject with great velocity and force if the
pintail breaks off or teeth/grooves strip. This may cause severe personal
injury.
To avoid pinch point, never place hand between nose assembly and work
piece.
Only use compatible equipment with this tool.
CAUTIONS: Remove
excess gap from between
the sheets. This permits
enough pintail to emerge
from collar for ALL jaw
teeth to engage with
pintail. If ALL teeth do not
engage properly, jaws will
be damaged.
Note: In certain situations,
it may be permissible to
use a BobTail tool and
fastener without a collar
to remove sheet gap prior
to full installation with a
collar. Consult qualified Huck
engineering personnel before
attempting this operation.
