Huck Model 201 (family) Sound Level
SEL --- 75.7 dB (A)
peak value = 104.4 dB (C)
For an eight hour work day, installing 3000 typical Huck fasteners will result in an
equivalent noise level (Leq) of 65.9 dB (A).
To calculate equivalent noise level for other quantities of fasteners in an eight hour
period, use the formula:
Leq = SEL + 10 log (n/28,800)
where n = number of fasteners in eight hours.
Huck Model 201 (family) Vibration Level
For an eight hour work day, installing 3000 typical Huck fasteners will result in an
equivalent weighted RMS vibration level (Aeq) of 12.25rn/s2.
To calculate the equivalent vibration level for other quantities of fasteners in an eight
hour period, use the formula:
Equivalent Vibration Level, Aeq (rn/s2) = (n/480) x 1.96
where n = number of fasteners in eight hours, and 1.96 (m/s2) = Aeq for 60 seconds
Test data to support the above information is on file at Huck International, Inc. Kingston, N.Y. Vibration
measurements are frequency weighted in accordance with ISO 8041 (1990).

Except where noted, these are WARNINGS
and involve possible serious personal
injury. There may be other WARNINGS,
Cautions and Notes in the manual that
must be observed when operating the
equipment:
I. Approved eye protection (e.g. safety
glasses) must be worn by the operator.
2. When using fasteners in some types of
structure, the fracturing of the pintail
during installation may generate noise
levels above the first action level of the
Noise at Work Regulations and therefore
approved hearing protection must be worn.
3. NEVER look directly at the front or rear
of the installation tool when it is in use.
4. NEVER use the nose assembly for a tool
handle. Do not grip the nose assembly
during fastener installation.
5. Keep hands/fingers clear of any moving
parts and away from holes in nose
assemblies.
6. DO NOT pull on a pin (fastener) without a
collar. When there is only one collar
chamfer, it MUST be out toward the tool
-- NOT against the workpiece. Fastener
will eject at high velocity when pintail
fractures and may cause serious injury.
7. DO NOT pull on a fastener’s pintail
without first placing the fastener in a
workpiece. Fasteners installed “in
air” will eject at high velocity when the
pintail fractures and may cause serious
injury.
8. Keep fingers clear from the underside of
the head (blind side) and collar of the
fastener. Keep fingers from within the
joint.
9. Do not look directly at the head, or blind
side, of fasteners during the installation
cycle.
10.KEEP HANDS CLEAR during the
installation cycle as the tool will pull and
straighten itself to the axis of the fastener.
Beware of hands being trapped against
any nearby structure.
11. NOTE: The trigger on the tool is the
operator’s direct link to controling swaging
movement. Releasing the trigger at any
time during the installation cycle will
immediately put the tool into reverse.
12.Beware of fastener pintails which are
ejected, (sometimes forcibly), when pintail
breaks during the installation cycle. The
pintail deflector, bottle, or catcher must
always be in place on the tool - - direct
deflector away from people.
13.Do not continue to use any equipment that
develops any type of malfunction while
being used.
14.Do not drag hoses and electrical cables.
Avoid kinking hoses.

switch ON, has two functions:
1. With tool in any position, vacuum holds
fastener firmly in nose assembly.
2. Vacuum expels broken pintail into pintail
collector.
•Weight of 2015: 4.9 lbs
•Weight of 2015B & 2015V: 5.2 lbs
•Min. Capacity: 2670 lbs @ 90 psi

Figure 1A - 2015V Outline Dimensions

When tool is connected to proper air supply,
air pressure holds throttle valve in the up
position - - air pressure is directed to the top of piston
keeping it down. Depressing trigger moves throttle
valve to the down position - - air is
directed to the bottom of the piston moving it
upward, air from above piston is exhausted
downward thru the throttle valve and exits the
muffler at bottom of tool. Air piston
rod is a hydraulic piston. Pressurized
fluid is forced into the cylinder head moving
pull piston rearward. The nose, which
is connected to the pull piston, will install the
fastener during the rearward piston movement.
8
2015 TOOLING HUCK FASTENERS
When fastener installation is completed, and
upon trigger release, air pressure causes
throttle valve to return to its up position - - air
flow reverses. The air piston and rod move
down to their starting position, exhausting air
from below the piston through the muffler at
bottom of tool. As rod moves downward and
hydraulic pressure is released from pull piston,
a spring behind pull piston returns it to its
starting position.

WARNING
As applicable, do not use without deflec-
tors or pintail bottles.
If deflectors are removed or damaged,
separated pintails may eject forcibly from
rear of tool. Unshielded eyes, especially,
may be permanently injured. Other severe
injuries can be caused by flying pintails. If
there is any chance of a projectile-like
ejection, always point rear of tool in a safe
direction, or be sure there is some struc-
ture that will stop ejecting pintails.
WARNING
To avoid pinch points, be sure there is
adequate clearance for tool and operator’s
hands before proceeding. Tool moving
toward structure may crush hands or
fingers between tool and structure if
clearance is limited.
The 2015 is equipped with a plastic plug in
the air inlet connector. Connector has 1/4-18
female pipe threads to accept the hose fitting.
Quick connect fittings and 1/4 inch inside
diameter air hose are recommended. An air
supply of 90-100 psi, capable of 4.3 CFM,
must be available. Air supply should be
equipped with a filter-regulator-lubricator unit.
PREPARATION FOR USE
MODEL 2015 TOOL All Models HUCK FASTENERS

NOTE: 2015V is sold with the ribbed
vacuum control ON/OFF slide in the forward
or OFF position. See FIGURE 10 for slides
location which is shown in the ON (rear)
position. While tool is not being used, move
slide to the OFF (forward) position to prevent
unnecessary air loss.
Nail Type Blind Fastener Installation:
The fastener may be placed, either in the work
hole or, in the end of the nose assembly. 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.
Warnings
Inspect tool for damage before each use.
Do not operate if damaged as severe
personal injury may occur.
Broken pintails eject from deflector with
speed and force - - be sure pintail deflector
is directed safely away from operator or other
personnel in the area. Ejecting pintails
striking anyone may cause serious personal
injury. For Models 2015B and 2015V,
pintail bottles must always be used. Replace
damaged pintail deflectors and bottles as
serious personal injury may occur from
pintails when using these defective parts.
Good Service Practice
Service Kits, 2015KIT and 20I5VKIT,
include perishable parts and should be on hand
at all times. Other components, as experience
dictates, should also bo kept for replacements.
ALWAYS REPLACE O-RINGS AND
BACK-UP RINGS WHEN TOOL IS
DISASSEMBLED FOR ANY REASON.
The efficiency and life of any tool depends
upon proper maintenance and good service
practices. Tool should be serviced by
personnel who are thoroughly familiar with it
and how it operates.
A clean, well-lighted area should be available
for servicing the tool. Special care must be
taken to prevent contamination of pneumatic
and hydraulic systems. Proper hand tools and
soft materials to protect tools must be
available. Use only standard hand tools, brass
drift and wood block. Vise with soft jaws
should be available. Unsuitable hand tools
will cause installation tool damage.
All parts must be handled carefully and
examined for damage and/or wear.
Components should be disassembled and
assembled in a straight line without bending,
cocking or undue force. Disassembly and
assembly procedures outlined in this manual
should be followed. If Huck recommended
procedures are not followed, the tool may be
damaged.
Rub SLIC-TITE TEFLON* thread compound,
or equivalent, on pipe plug threads and quick
connect fitting.
CAUTION: Do not use TEFLON tape on
pipe threads. Pipe threads may cause tape
to shred resulting in tool malfunction.
(SLIC-TITE is available in stick form, as
503237, from Huck.)
OPERATING INSTRUCTIONS
MAINTENANCE

2015 TOOLING HUCK FASTENERS
Tool Maintenance
The 2015 series require a minimum amount of
maintenance. Regular inspection and
correction of minor problems will keep the
tool operating efficiently and prevent
downtime.
Using filter-regulator-lubricator unit is highly
recommended for safe and reliable tool
operation. If a filter-regulator-lubricator unit is
not being used in the air supply: (1) remove
hose fitting from air inlet connector and drop
in a few drops of automatic transmission fluid
or light oil (2) blow out air line to remove dirt
and water before connecting air hose to tool.
At regular intervals, depending upon use,
replace all seals in tool. Service Kits should
be kept on hand. (See SPARE PARTS AND
SERVICE KITS.) Inspect both hydraulic
pistons, and their piston rods for scored
surfaces, excessive wear or damage, and
replace as necessary.
Always replace seats and back-up rings when
tool is disassembled for any reason to assure
proper sealing and tool function.
Nose Assembly Maintenance
Caution
Damaged jaw teeth, or debris packed
between teeth, will result in failure to install
fastener or improperly installed fastener.
Frequently cleaning the nose assembly is
recommended. Remove nose assembly from
tool and disassemble - - see DISASSEMBLY.
Check components for any signs of damage,
e.g. cracks, scores and damaged spring. Check
gripper teeth for damage. Remove any debris
packed between teeth with a sharp pointed
“pick”. Periodically dip nose, while cycling
tool, in mineral spirits, isopropyl alcohol or
other suitable solvent, to clean jaws and wash
away metal chips and dirt.
Smear LUBRIPLATE* 130AA, or equivalent
lubricant, on O-rings and mating surfaces to
aid assembly and to prevent damage to
O-rings. (LUBRIPLATE 13OAA is available
