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.
