Operating Instructions
HUCKBOLT® FASTENER INSTALLATION:
Place pin in workpiece and place collar over pin. See
WARNING. (If Collar has only one tapered end, that end
MUST be out toward tool - not next to workpiece.) Hold
pin and push nose assembly onto pin protruding through
collar until nose anvil touches collar. Depress trigger and
hold until collar is swaged and pintail breaks. Release
trigger. Tool will go into RETURN stroke. Tool and nose are
ready for next installation cycle.
BLIND FASTENER INSTALLATION:
Fastener may be placed in workpiece or in end of nose
assembly . See WARNING. In either case, tool/nose must be
held against work and at right angles to it. Depress and
hold trigger until fastener is installed and pintail breaks.
Release trigger. Tool will go into its return stroke. Tool/nose
are ready for next installation cycle.
CAUTIONS:
Do not let disconnected hoses and couplers
contact a dirty floor. Keep harmful material out
of hydraulic fluid. Dirt in hydraulic fluid causes
valve failure In Tool and In Powerig Hydraulic
Unit.
Do not use TEFLON® tape on pipe threads.
Pipe threads may cause tape to shred resulting
in tool malfunction. (Threadmate™ is available
from Huck in a 4oz. tube as part number
508517.)
Remove excess gap from between the sheets to
permit correct fastener installation and prevent
jaw damage. ALL jaw teeth must engage pintail
to avoid damaging teeth.
BOM blind fasteners jam in nose assembly if
pulled when not in workpiece.
To avoid structural and tool damage, be sure
enough clearance is allowed for nose assembly
at full stroke.
Do not abuse tool by dropping it, using it as a
hammer or otherwise causing unnecessary
wear and tear.
WARNINGS:
Read full manual before using tool.
Inspect tool for damage or wear before each
use. Do not operate if damaged or worn, as
severe personal injury may occur.
A half-hour training session with qualified
personnel is recommended before using Huck
equipment.
When operating Huck installation equipment,
always wear approved eye protection.
Be sure there is adequate clearance for the
operator’s hands before proceeding.
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. Be sure
that pintail deflector is on tool and directed
away from all personnel.
Do not pull on a pin without placing
fastener/collar in a workpiece, and also, collar
chamfer MUST be out toward tool - - these
conditions cause pin to eject with great velocity
and force when the pintail breaks off or
teeth/grooves strip. This may cause severe
personal injury.
This tool is shipped with an attached regulator and a 1/4” inside diameter air hose (Huck p/n 115436), with a plastic plug
in the air inlet connector. An air supply capable of 6.3 CFM at a pressure greater than 10 psi greater than the installed
regulator set point (Figure 16) must be available. Air supply should be equipped with a filter-regulator-lubricator unit.
Do NOT pull a
fastener with the
collar upside down.
