2015 series Pneudraulic Installation Tools (HK958)
Description
The 2015 series tools are lightweight, high-speed production
tools that install 3/32” and 1/4” nail-type blind fasteners. An
integral nose assembly increases reliability and simplifies use of
this tool.
The 2015V model has a Tubing & Slide Assembly - a ribbed
“ON/OFF” vacuum-regulating slider that enhances the tool
capabilities by expelling broken pintails into the pintail
collector, and holding fasteners firmly in the nose assembly,
with the tool in any position.
When the tool is not in use, the OFF position (slider forward)
will prevent air loss. See Figure 5 for the location of this
assembly (pictured in the ON position) on the tool.
The pulling action of the pull piston is provided by a
pneumatic-hydraulic (pneudraulic) intensifier system that
is powered by 90 psi (6.2 bar) air pressure. The air inlet is
equipped with a connector with 1/4”-18 female pipe threads to
accept your air hose or quick-connect fitting. The piston return
stroke is spring actuated.
Specifications
STROKE: 0.683 in (1.73 cm)
WEIGHT: 2015: 4.9 lbs (2.22 kg)
2015B & 2015V: 5.2 lbs (2.36 kg)
MAX AIR PRESSURE: 90 psi (6.2 bar)
MAX FLOW RATE: 4.3 scfm (121.76 l/min)
POWER SOURCE: 90 psi (6.2 bar) maximum shop air
MAX OPERATING TEMP: 125° F (51.7° C)
PULL CAPACITY: 2670 lbs @ 90 psi
(11.88 kN @ 6.2 bar)
SPEED / CYCLES: 30 per minute
HOSE KITS: Use only genuine Huck Hose Kits rated @ 10,000
psi (689.5 bar) working pressure.
HYDRAULIC FLUID: Hydraulic fluid shall meet DEXRON®III,
DEXRON VI, MERCON®, Allison C-4 or equivalent Automatic
Transmission Fluid (ATF) specifications. Fire-resistant fluid may
be used if it is an ester-based fluid such as Quintolubric®HFD
or equivalent. Water-based fluid shall NOT be used as serious
damage to equipment will occur.
DEXRON is a registered trademark of General Motors Corp.
MERCON is a registered trademark of Ford Motor Corp.
Quintolubric is a registered trademark of Quaker Chemical Corp.
PULL STROKE:
When tool is connected to the air supply, the
air pressure holds the throttle valve in the up
(RETURN) position; air pressure is directed
to the top of the air piston, keeping it down.
When the trigger is pressed, the throttle
valve moves down to the PULL position, and
pressurized air is directed to the bottom of
the air piston, causing it to move upward.
The air above the air piston is exhausted and
directed through the center of the throttle
valve and out the bottom of the tool (through
the muffler). As the hydraulic piston rod
moves upward, a column of pressurized fluid
is forced into head, which moves the pull
piston rearward. The attached nose assembly
moves with the pull piston to start fastener
installation.
RETURN STROKE:
When fastener installation is completed, the
trigger is released. Air pressure, with the
assistance of a spring, sends the throttle valve
to the up (RETURN) position. Pressurized air
is re-directed to the top of the air piston (see
above), causing it and the hydraulic piston rod
to move downward. The air from below the
piston is exhausted through the bottom of the
tool. The piston and hydraulic piston rod move
downward, hydraulic pressure is reversed, and
the pull piston is returned forward.

preparation for uSe
The 2015 tools ship with a plug in the air inlet
connector. The connector has 1/4”-18 female pipe
threads to accept the air-hose tting. Huck recommends
quick-disconnect ttings and a 1/4” inside-diameter
air hose. The air supply should have a lter-regulator-
lubricator unit and access to 90 psi (6.2 bar), capable of
a ow rate of 2.9 CFM (170 l/m).
NOTE: Quick-disconnect ttings and air hoses are
not available for purchase from Huck International,
Inc. Huck includes an air hose (P/N 115436) to
facilitate immediate tool use.
1. Remove the shipping plug from air inlet connector
and add a few drops of an approved hydraulic uid.
2. Screw the quick-disconnect tting into the air inlet
connector.
3. Set the air pressure on the regulator to 90 psi (6.2
bar), and connect the air hose to the tool and the air
inlet connector.
4. Press and release the trigger a few times to cycle
the tool.
5. Disconnect the air hose from the tool, and remove
the retaining nut. Select the proper nose assembly
for the fastener being installed.
6. Connect the air hose to the tool and install fasteners
in a test plate of proper thickness with proper size
holes. Inspect the fasteners.
If the fasteners do not pass inspection, consult the
TroubleshooTing section to investigate possible causes.

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
ngers between tool and structure if
clearance is limited.
WARNING:
As applicable, do not use without
deectors or pintail bottles.
If deectors 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 ying 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
structure that will stop ejecting pintails.
CAUTION: Do not use TEFLON®tape on
pipe threads. Tape can shred and break free
into uid lines, resulting in malfunctions.

Read all of these instructions in order to ensure the safe operation of this equipment.
This section details installing Huck Blind Fasteners.
Review all CAUTIONs and WARNINGs prior to installing
these fasteners. If the tool malfunctions, consult the
TroubleshooTing section before attempting any repairs.
NOTE: Reasonable care of tools by operators is
an important factor in maintaining efciency and
reducing downtime.
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.
CAUTION:
• BOM blind fasteners will jam in the
nose assembly if they are pulled when
not in a workpiece.
• To avoid structural and tooI damage, be
sure there is sufcient clearance for the
nose assembly at full stroke.
• Remove excess gap from between
the sheets to permit proper fastener
installation and prevent jaw damage.
ALL jaw teeth must engage the pintail
to avoid damaging the teeth.
CAUTION: Ensure the tool has been
properly re-assembled prior to use.
WARNINGS:
• Wear approved eye and hearing
protection.
• Ensure adequate clearance for
operator’s hands before installing
fasteners.
• Be sure that pintail deector is attached
to the tool and directed away from all
personnel.
• Do not pull on a pin without placing a
fastener in a workpiece. Make sure that
the collar chamfer is out, toward the
tool. Pins eject with great velocity when
pintails break off or teeth/grooves strip,
which could cause serious injury.
WARNINGS:
Inspect tools for damage and wear before
using. Do not use if damaged or worn;
serious personal injury may occur.
Pulling a pin without a collar, or with collar
chamfer against workpiece, may result in
the pin becoming a high-speed projectile
when the pin grooves are stripped or the
pintail breaks off. Serious personal injury
may occur to anyone in the pin’s “ight
path.” This includes pin ricochet.
Broken pintails eject from the deector
with speed and force. To reduce the risk of
serious personal injury, be sure the pintail
deector is properly attached and directed
away from all personnel.
Pintail bottles must always be used with
models 2015B and 2015V. To reduce the risk
of serious personal injury, do not operate
tool with a damaged pintail deector or
pintail bottle; replace these parts if they are
damaged.

This procedure is for the assembly of the tool. For
component identication, see Figures 4–7.
BEFORE RE-ASSEMBLING THE TOOL:
• Clean components with mineral spirits or a similar
solvent. Inspect for wear/damage and replace as
necessary.
• Use the O-rings, Quad-rings, and Back-up rings
from the appropriate Huck Spare Parts Service Kit
(P/N 2015KIT or 2015VKIT). When assembling the
tool, take care not to damage O-rings, Quad-rings,
Back-up rings.
Smear LUBRIPLATE® 130-AA (Huck P/N 502723)
or SUPER-O-LUBE® (Huck P/N 505476) on rings
and mating parts to ease assembly.
IF THE BUSHINGS WERE REMOVED FROM THE
CYLINDER:
• Use an arbor press and apply Loctite®#609,
(503377) on the bushings before pressing them into
the cylinder. Place the chamfered end of the upper
bushing in the top of the cylinder. Carefully press
the bushing squarely into the cylinder. Repeat the
procedure for the lower bushing.
TO RE-ASSEMBLE THE TOOL:
1. Assemble the gland assembly. Replace the
Polyseal, spacer, and retaining ring. Install the
adapter into the cylinder handle/head.
NOTE: Note the orientation of the Polyseal in the
Assembly Drawings in this manual.
2. Thread the Polyseal Insertion Tool (P/N 121694-
202) into the handle assembly.
3. Thread the Piston Assembly Tool (P/N 123111-
4), onto the piston assembly. Push the front gland
assembly (except for wiper seal) onto the piston.
Then slide the wiper seal onto the piston.
4. Use a press, or a soft mallet and wood or brass
drift, and gently push the assembled components
into the handle assembly from the rear.
5. Remove the Piston Assembly Tool and Polyseal
Insertion Tool.
6. Model 2015: (Figure 4) Assemble the spring,
spacer, rear wiper seal, and end cap into handle/
head.
Models 2015B & 2015V: Reverse the instructions
in speciAl DisAssembly insTrucTions for 2015b AnD
2015V in the DisAssembly section.
7. Position cable assembly in trigger slot and push
the dowel pin through holes in trigger and cable
assembly. Position assembled trigger in handle and
drive roll pin through holes in handle and trigger.
8. Secure the handle assembly upside-down in a soft-
jaw vise. Place the inverted cylinder assembly on
the base of the handle. The cylinder pin maintains
the orientation.
9. Apply Loctite®243™to the threads of the gland
assembly. Screw the gland assembly into the
handle assembly. Use a 1-3/8” socket wrench to
tighten and torque to 36–66 ft.-lbs.
10. Push the bumper rmly over the gland. (The slots
must face the bottom of the tool.)
11. Clean the piston rod threads and apply Loctite®
243™. Carefully press the assembled air piston and
piston rod into the cylinder just enough to allow
installation of the cylinder head assembly.
12. Secure the head upside-down in a vise. Push the
cylinder head squarely into the cylinder, taking care
not to damage O-ring. Install the retaining ring; align
the screw holes with the mufer end cap. (Figure 6)
13. Position mufer in the center of the cylinder head.
Position the gasket on the cylinder assembly, taking
care to note the direction of the lip in Figure 6.
14. Carefully position the mufer end cap on the
cylinder, making sure that it is properly positioned in
the recess of the bottom plate. Secure the mufer
end cap with the three button head screws using a
1/8” hex key.
15. Place the tool upright on a level surface. Drop the
spring into the throttle valve bore in the cylinder,
and push the throttle valve assembly into the
cylinder.
16. Place the ball end of the cable assembly in the
end of throttle arm. Slide throttle arm into slot on
cylinder.
17. Insert the pivot screw into the cylinder to retain the
throttle arm.
18. Screw anvil insert into anvil holder. (Figures 4 & 5)
19. Assemble the collet with all necessary components,
and screw the assembled collet onto the piston rod;
tighten securely.
20. Screw the anvil holder into the adapter.
The tool is now assembled and must be lled with
hydraulic uid prior to use. See the fill AnD bleeD
section. NOTE: Install the bleed plug and O-ring
assembly after that process.

fill and bleed
This section documents the “bleed-&-ll” procedure. For
component identication, see Figures 2–2B.
REQUIRED EQUIPMENT
• DEXRON® III or equivalent ATF (See specificATions
for more information.)
• Shop air-line with 90 psi (6.2 bar) max.
• Air regulator
• Fill Bottle Assembly (P/N 120337, included with
tool)
• Large at-blade screwdriver
• Nose assembly or optional stall nut (P/N 125340)
and stop (P/N 125341)
NOTE: The stall nut is used to load the tool
during bleeding and for measuring tool stroke.
See KiTs & Accessories.
• Fasteners (optional)
PREPARATION
• Install air regulator in
the air-line and set
the pressure to 20–40
psi (1.4–2.8 bar).
• Add an approved
hydraulic uid to the
ll point of the ll
bottle. (Figure 2)
TO BLEED AND FILL THE TOOL:
1. Connect tool to the air supply to seat the air piston
at the bottom of the air cylinder; then disconnect.
Lay tool on its side with ll port facing up.
2. Remove the bleed plug from the ll port. Screw the
ll bottle into the ll port. (Figure 2A)
3. Connect tool to the air supply and stand it upright.
4. Hold the ll bottle at a right angle (90°) to the tool
(Figure 2B); cycle the tool 20–30 times; watch for air
bubbles escaping into the bottle.
NOTE: Rock the tool to free trapped air. Do not
allow air to re-enter the tool. Always hold the ll
bottle as shown in order to prevent drawing in
air.
4. When air bubbles stop accumulating in the ll
bottle, stop cycling the tool. When the trigger is
released, the pull
piston returns to the
idle (full forward)
position. Disconnect
the tool from the air
supply.
5. Lay the tool on its
side, and remove
the ll bottle.
Carefully add uid
to “top off” the uid
in the ll port. Insert
and tighten the
bleed plug.
6. Connect the tool to the air supply to check the tool
stroke. NOTE: There are two procedures for
measuring tool stroke: with and without a stall
nut. See meAsuring Tool sTroKe.
If the stroke is less
than recommended
minimum, remove
the bleed plug and
add uid. Then
re-insert the plug
and re-check the
stroke.
If the uid level
drops, repeat steps
until the uid level
does not drop when
the tool is cycled.
NOTE: This usually requires 3 or 4 repetitions.
When the tool stroke is as recommended:
a. Increase air pressure according to specications.
b. Install two fasteners to check function and
installation in a single stroke (or cycle the tool with
the stall nut fully threaded onto the piston).
c. Re-measure the stroke.
Repeat this process until stroke is at minimum
requirement.

WARNING: Avoid contact with hydraulic
uid. Hydraulic uid must be disposed of
in accordance with local regulations. See
MSDS for hydraulic uid shipped with tool.

WARNING: Air pressure must be at 20–40
psi (1.4–2.8 bar) to prevent possible injury
from high-pressure spray.
Before cycling the tool, make sure the:
• bleed plug is tightened in the ll port, or
• ll bottle is securely attached to the tool
(if the bleed plug has been removed), or
• ll port is held over a container. (Figure

BLEED PROCEDURE FOR PARTIALLY FILLED
TOOL IN FIELD USE
1. Disconnect the tool from the air supply. Lay tool on
its side with ll port facing up.
2. Remove the bleed plug from the ll port, and
position ll port over suitable container. (Figure 2A)
3. Connect the tool to the air supply and cycle it
several times to drain uid, air, and foam.
4. Screw the ll bottle into the ll port.
5. Connect the tool to the air supply, with the pressure
set at 20–40 psi (1.4–2.8 bar).
6. Stand tool upright. While slowly actuating the trigger
(20–30 cycles), attach the ll bottle at a right angle
(90°) to the tool (Figure 2B) and watch for escaping
air bubbles.
7. When air bubbles stop accumulating in the ll bottle,
stop cycling the tool. When the trigger is released,
the pull piston returns to the idle (full forward)
position. Disconnect the tool from the air supply.
8. Lay the tool on its side, and remove the ll bottle.
Carefully add uid to “top off” the uid in the ll port.
Insert and tighten the bleed plug.
9. Connect the tool to the air supply to check the tool
stroke.
NOTE: There are two procedures for measuring
tool stroke: with and without a stall nut. See
meAsuring Tool sTroKe.
If the tool stroke is less than the recommended
minimum length, remove the bleed plug and add uid.
Then re-insert the bleed plug and re-check the stroke.
The uid level may drop slightly. If so, repeat these steps
until the uid level does not drop when the tool is cycled.
NOTE: This usually requires 3 or 4 repetitions.
When the tool stroke is as recommended:
a. Increase the air pressure according to the tool
specication.
b. Install two fasteners to check function and
installation in a single stroke (or cycle the tool with
the stall nut fully threaded onto the piston).
c. Re-measure the stroke.
Repeat this process until the tool stroke is at the
recommended minimum length.
