I. GENERAL SAFETY RULES:
1. A half-hour long hands-on training session with qualified
personnel is recommended before using Huck equipment.
2. Huck equipment must be maintained in a safe working
condition at all times. Tools and hoses should be inspected
at the beginning of each shift/day for damage or wear. Any
repair should be done by a qualified repairman trained on
Huck procedures.
3. For multiple hazards, read and understand the safety
instructions before installing, operating, repairing, maintaining,
changing accessories on, or working near the assembly power
tool. Failure to do so can result in serious bodily injury.
4. Only qualified and trained operators should install, adjust or
use the assembly power tool.
5. Do not modify this assembly power tool. This can reduce
effectiveness of safety measures and increase operator risk.
6. Do not discard safety instructions; give them to the operator.
7. Do not use assembly power tool if it has been damaged.
8. Tools shall be inspected periodically to verify all ratings
and markings required, and listed in the manual, are legibly
marked on the tool. The employer/operator shall contact
the manufacturer to obtain replacement marking labels
when necessary. Refer to assembly drawing and parts list for
replacement.
9. Tool is only to be used as stated in this manual. Any other use
is prohibited.
10. Read MSDS Specifications before servicing the tool. MSDS
specifications are available from the product manufacturer
or your Huck representative.
11. Only genuine Huck parts shall be used for replacements or
spares. Use of any other parts can result in tooling damage
or personal injury.
12. Never remove any safety guards or pintail deflectors.
13. Never install a fastener in free air. Personal injury from
fastener ejecting may occur.
14. Where applicable, always clear spent pintail out of nose
assembly before installing the next fastener.
15. Check clearance between trigger and work piece to ensure
there is no pinch point when tool is activated. Remote
triggers are available for hydraulic tooling if pinch point is
unavoidable.
16. Do not abuse tool by dropping or using it as a hammer. Never
use hydraulic or air lines as a handle or to bend or pry the
tool. Reasonable care of installation tools by operators is an
important factor in maintaining tool efficiency, eliminating
downtime, and preventing an accident which may cause
severe personal injury.
17. Never place hands between nose assembly and work piece.
Keep hands clear from front of tool.
18. Tools with ejector rods should never be cycled without nose
assembly installed.
19. When two piece lock bolts are being used always make sure
the collar orientation is correct. See fastener data sheet for
correct positioning.
II. PROJECTILE HAZARDS:
1. Risk of whipping compressed air hose if tool is pneudraulic
or pneumatic.
2. Disconnect the assembly power tool from energy source
when changing inserted tools or accessories.
3. Be aware that failure of the workpiece, accessories, or the

ERT_S series Ebbert Rivet Tools (HK1038)
General Information
This manual contains operating and service procedures
for the Ebbert Rivet Tool models ERT1S, ERT2S,
ERT3S, ERT4S, and their optional tool congurations.
It is suggested that close attention be directed to the
recommended service procedures in this manual.
Specic instructions for each tool are given under that
tool model number heading. While they may appear to
be similar, each tool contains parts not used on other
models, and removal and replacement methods may
vary.
Principle of Operation
Incoming non-oiled plant air is regulated at 90psi
through the Air Filter/Regulator to the Four-way Valve on
the Power Unit and through the Red Air Line to the valve
in the rivet tool handle.
When the tool trigger is pulled, a trigger/plunger unseats
a valve ball and directs air from the tool handle back
through the Green Air Line to the Four-way Valve. The
Four-way Valve is shifted, directing air pressure through
the Blue Air Line into the Power Booster. As the Power
Booster air piston advances, hydraulic uid is forced
through the black Hydraulic Line into the tool, forcing
the tool to retract. This delivers the necessary force to
install the fastener and break the pintail. (In the EPS1V,
the pintail then travels through the pintail collection tube
from the tool into the Pintail Collection Box.)
When the trigger is released, the Four-way Valve shifts
to its default position; air pressure returns the Power
Booster air piston to the full-back position and the tool
piston to the full-forward position. The cycle is complete.

Disassembly ERT1S & ERT2S
This procedure is for the complete disassembly of the
ERT1S & ERT2S tools. For component identication,
see Figure 2.
1. Unscrew two socket head screws (ERT1S) or four
screws (ERT2S) that secure piston rod guide to the
front of the tool, and remove piston rod guide.
2. Loosen hose clamp/sleeve at rear of tool, and pull
it back far enough to allow clearance for removal of
end cap. From rear of tool, remove two socket head
screws (ERT1S) or four screws (ERT2S) and support
loop assembly.
3. Push piston toward rear of cylinder to remove end
cap/guide tube assembly, piston, and piston forward
stop.
4. Remove remaining seal from front of cylinder.
5. The cylinder is now stripped of parts except retaining
ring. For typical tool service, it is not necessary to
remove this retaining ring. If it is removed, when
replacing it, relocate retaining ring ears at bottom of
cylinder, allowing clearance for hydraulic inlet port.
6. ERT1S: Remove retaining ring and all seals from
piston, and piston rod wiper from piston rod guide.
ERT2S: Remove retaining ring, front seal retainer
and all seals from piston, and O-ring, Back-up ring,
seal, and piston rod wiper from piston rod guide.
NOTE: When servicing the tool to this extent, the
piston rod wiper must be replaced.
7. Remove the O-ring from the end cap.
8. Clean disassembled parts in cleaning solution. While
cleaning the piston, ensure that the small hole in the
“V” groove is open.
Figure 2
Assembly ERT1S & ERT2S
This procedure is for the re-assembly of the ERT1S &
ERT2S tools.
1. When replacing seals, make sure they are correctly
positioned as shown on the Tool Schematic. Wipe
all seals with a thin lm of seal lubricant before
reassembly.
2. It is important to inspect the cylinder wall to ensure
surface is free of gouges and nicks that will damage
a new seal. Small nicks and gouges can be removed
using a ne crocus cloth.
3. After all seals, O-rings and Back-up rings are
replaced:
ERT1S: With piston forward stop placed on the piston
shaft, insert end cap assembly into piston, then slide
the complete assembly into tool cylinder.
ERT2S: Insert end cap assembly into piston, then
slide the complete assembly into tool cylinder.
NOTE: Use caution when inserting this assembly
into cylinder to keep piston from cocking in
cylinder and nicking cylinder wall. This could
ultimately cause a seal edge to be cut.
Secure end cap and support loop assembly with two
screws (ERT1S) or four screws (ERT2S).

Disassembly ERT3S & ERT4S
Assembly ERT1S & ERT2S (continued)
This procedure is for the complete disassembly of the
ERT3S & ERT4S tools. For component identication, see
Figure 3.
1. Remove the handle from the front of the tool.
2. Loosen the hose clamp/sleeve at the rear of the tool,
and pull it back far enough to allow clearance for the
removal of the end cap.
3. After removing support loop assembly, piston and end
cap can be removed by pushing back on front of the
piston for removal through back of the tool.
4. Remove O-ring from end cap.
5. The front seal retainer must be removed from the front
of the tool. This retainer is a snug t and requires a soft
hammer blow to the end of a brass dowel held against
the seal retainer.
6. The cylinder is now stripped of parts except the
retaining ring. For typical tool service, it is not necessary
to remove this retaining ring. If it is removed, when
replacing it, relocate retaining ring ears at the bottom of
the cylinder, allowing clearance for the hydraulic inlet
port.
7. ERT3S: Remove retaining ring, piston forward stop,
and all seals from the piston.
ERT4S: Remove retaining ring, piston seal retainer
and all seals from the piston, and O-ring, Back-up ring,
and hydraulic seal from the front seal retainer.
NOTE: When servicing the tool to this extent, the
piston rod wiper must be replaced.
8. Clean disassembled parts in cleaning solution. While
cleaning the piston, ensure that the small hole in the “V”
groove is open.

4. Reposition tool in vise with open front of cylinder
pointing straight up. Use option “a” or “b” to ll tool
with hydraulic uid:
a) Gravity ll: Connect hydraulic line to power unit
and allow hydraulic uid to ow from the higher
positioned reservoir into tool cylinder until it is level
with the front retaining ring; then disconnect hydraulic
line for installation of remaining components.
b) Optional ll: Using Model 300509 Bleed Pump
Assembly, pump from hydraulic connector through
the line; lling the tool in the same manner and to the
same level as above.
5. ERT2S: Replace front seal retainer by positioning the
cut-out section so it will clear the two ears of retaining
ring when it is dropped into place. If retainer does
not lay at, tap it gently with a screwdriver until it
assumes a at position.
6. Slide the hydraulic seal down over piston threads and
wrench ats carefully to prevent nicking seal edges.
7. ERT1S: Insert piston rod guide and wiper assembly,
pushing the hydraulic seal down into cylinder. Secure
piston rod guide with two screws. Torque screws at
both ends of the tool to 12–15 ft-lbs.
ERT2S: It is not necessary to push the seal all the
way into cylinder. It will assume its position in the
piston rod guide when the guide is next installed and
secured with two bearing plates and four screws.
Torque screws at both ends of tool to 60–80 in-lbs.
This method of relling the tool with hydraulic uid
relieves any further requirement for bleeding air. The
tool can now be connected to power unit and be
test-cycled. The pulling head assembly can now be
installed.

ERT_S series Ebbert Rivet Tools (HK1038)
Assembly ERT3S & ERT4S
This procedure is for reassembly of ERT3S & ERT4S.
1. When replacing seals, make sure they are correctly
positioned as shown on the Tool Schematic. Wipe all seals
with a thin film of seal lubricant before reassembly.
2. It is important to inspect the cylinder wall to ensure the
surface is free of gouges and nicks that will damage a new
seal. Small nicks and gouges can normally be removed
using a fine crocus cloth.
3. After all seals, O-rings and Back-up rings are replaced,
insert end cap assembly into piston, and insert as a
combination into the tool cylinder. NOTE: Use caution
when inserting this assembly into cylinder. Keep
the piston from cocking in the cylinder and nicking the
cylinder wall. This could ultimately cause a seal edge to be
cut. Secure the end cap and support loop assembly with
four screws.
4. Reposition the tool in the vise with the open front of the
cylinder pointing straight up. Use Option “a” or “b” for
filling the tool with hydraulic fluid:
a) Gravity fill: Connect the hydraulic line to the power
unit and allow hydraulic fluid to flow from the higher
positioned reservoir into the tool cylinder until it is level
with the front retaining ring, then disconnect the hydraulic
line for installation of remaining components.
b) Optional fill: Using the Model 300509 Bleed Pump
Assembly, pump from the hydraulic connector through
the line, filling the tool in the same manner and to the
same level as above.
5. ERT3S: Slide the front seal retainer down, using care to
get it positioned straight in the cylinder. The retainer does
not easily slide into the cylinder; it will be drawn into place
later when the handle is secured.
ERT4S: Making sure the cut-out section will clear the
ears of the retaining ring, slide front seal retainer down,
using care to get it positioned straight in the cylinder. The
retainer does not easily slide into the cylinder; it will be
drawn into place later when the handle is secured.
6. Slide hydraulic seal down over piston threads and wrench
flats carefully to prevent nicking seal edges, and position
in cylinder (ERT3S) or front seal retainer (ERT4S).
Positioning this seal requires some effort to work it in.
Start it down on one side and slowly work it in until the
last small area may be assisted by using the flat side of a
common screwdriver.
7. Install handle and piston rod wiper down over piston and
into contact with front seal (ERT3S) or front seal retainer
(ERT4S). While doing this, hold trigger in position to
allow it to drop behind lock-in pin. Install four screws with
bearing plates with equal pressure to draw handle (and
seal retainer - ERT4S) into position in cylinder. Torque
screws at both ends of the tool to 60–80 in-lbs.
8. Air-bleed tool if necessary and connect to the power
unit for test cycle. The pulling head assembly can now be
installed.

ERT_S series Ebbert Rivet Tools (HK1038)
Rivet Tool Handle Function
The rivet tool handle contains the air valve mechanism which,
when actuated, initiates the rivet station cycle.
Figure 4A shows the valve components in the “at rest”
position. The steel ball is sealing air pressure within the red air
line chamber.
Figure 4B shows how the double Quad-rings function to
seal the forward section of the chamber when the trigger is
pressed, directing air pressure through the green air line back
to the Four-way Valve.
After prolonged use, the Quad-rings will wear down resulting
in a poor seal when the trigger is actuated. This can slow
down the cycle time of the tool due to the rivet tool operator
holding the trigger in a tighter position when setting the rivet.
It is easy to remedy the problem. Remove the trigger pin,
trigger, and valve plunger for Quad-ring replacement.
On models ERT1S and ERT2S, the handle is adjustable through
a 20-degree arc. This patented design allows relief to the wrist
when work heights are high or low to the operator’s normal
body position.
Each tool is provided with a 5/32” hex ball driver for the
handle adjustment. By loosening the socket head screw
located inside the handle, the handle can be moved into the
desired position and locked into that location with the hex ball
driver.
In some operations requiring excessive loads on the handle, it
is suggested that the clamp block be reversed, placing the flat
surface into contact with the handle for higher locking force.
NOTE: Make sure the trigger is square to the handle slot
and moves freely after tightening the clamp block.
1. Disconnect the rivet tool air-line from the Power Unit.
2. Attach Bleed Pump 300509 to the hydraulic hose on the rivet tool.
3. Remove the bleed screw from the tool.
4. Pump the bleed pump until no more bubbles appear out of the bleed port of the tool.

Troubleshooting
1. Slow tool cycle.
a. Check air pressure and hydraulic pressure. Reference
Principle of Operation schematic on page 5 of this
manual.
b. Incoming air-line must be 3/8” ID minimum. If longer
that 20’, air-line should increase to 1/2” ID.
2. Tool will not pull rivet.
a. Air in hydraulic system; requires bleeding.
NOTE: Air entrapment is identifiable by sound. As trigger is
actuated, the normal “thud” produced by the power unit is
replaced by a metallic “clack”.
To bleed rivet tool, fill the reservoir, and:
1. Unhook RED air-line from power unit.
2. Lay tool in pan and remove bleed screw.
3. Allow fluid to flow until it is free of bubbles.
If condition persists, replace the seals.
b. 1. Unhook RED air-line from power unit.
2. Attach Filler / Bleed Pump Assembly to tool
hydraulic hose.
3. Remove bleed screw on Rivet Tool.
4. Pump the Bleed Pump until bubbles quit coming out
of the bleed port on the tool.
Always check the simplest possible cause (such as a disconnected air hose) of a malfunction first. Then proceed logically,
eliminating other possible causes until the cause is discovered. Where possible, substitute known good parts for suspected
defective parts. Use this troubleshooting information to aid in locating and correcting trouble.
