LOCKBOLT® FASTENER INSTALLATION:
Place pin in work hole and place collar over pin. See
WARNING. (If Collar has only one tapered end, that end
must be out toward tool, not next to sheet.) Hold pin and
push nose assembly onto pin protruding through collar
until nose assembly anvil touches collar. Depress trigger
and hold depressed until collar is swaged and pintail
breaks. Release trigger and tool will go into return stroke.
The tool and nose assembly are ready for the next fastener
installation cycle.
BLIND FASTENER INSTALLATION:
Remove excess gap from between the sheets to
permit correct fastener installation. Fastener may be placed
in work hole or in end of nose assembly. See WARNING. In
either case, tool and nose assembly must be held against
work and at right angles to it. Depress trigger and hold
it depressed until fastener is installed and pintail breaks.
Release trigger and tool will go into its return stroke.
The tool and nose assembly are ready for next fastener
installation cycle.
READ ALL WARNINGS AND CAUTIONS PRIOR TO USING YOUR SYSTEM. Failure to understand
WARNINGS may cause serious personal injury. Failure to understand CAUTIONS may cause damage to
structure and Tool. Additional safety information can be found on page 4.
CAUTION: 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
stripped and/or damaged.
WARNING: Do not pull on a pin without a
collar. The pin will eject with velocity and
force when the pintail breaks off. This may
cause serious injury.
WARNING: Do not pull on a fastener’s pin
without rst placing fastener In a work piece.
The fastener will eject forcibly when the pintail
breaks off. This may cause serious Injury.
CAUTION: To avoid structural and Tool
damage, be sure enough clearance is allowed
for nose assembly at full stroke. Do not abuse
the tool by dropping it, using it as a hammer
or otherwise causing unnecessary wear and
tear. Reasonable care of installation tools by
operators is an Important factor in maintaining
tool efciency and reducing downtime.
