Important: Do not operate the tool before reading these instructions
The Auto-Spreader™ HS10K is designed for spreading and lifting. It
is a small, light and powerful precision tool. It generates 10,000 lbs. of
spreading force by using hydraulic power. It is extremely versatile, and
can be used wherever lifting power is needed.
Some Common Applications:
• Flange Spreading
• Controlled Lift, Level, and Align Heavy Equipment
• Shaft Replacement
• Impeller Replacement
• Separate Manways
• Change Gaskets, Turn Blinds
• Hydraulic Model Allows for Remote Opening of Flanges
The Auto-Spreader is simple to use. To spread the feet, connect the hydraulic cylinder to a hydraulic pump and pressurize it. To close the feet,
release the pressure of the pump. The cylinder has a spring return.
The Auto-Spreader only needs .09” or 2.3 mm gap to engage the feet. It
has a separating capacity of 3” spread under full load. The high strength
alloy steel forged feet close automatically when the pressure is released.

Note: When using the Auto-Spreader for fl ange spreading, it is recommended that two Auto-Spreaders be used. Place the fl ange spreaders on
opposite sides of the fl ange for even spreading. See fi gure 1.
Maximum Spreader Extension
A red mark will appear on the shaft of the center foot, when maximum
safe extension is achieved. See fi gure 2.
Creating pressure beyond the 10,000 PSI rated capacity may result
in injury.

Safety Tips
• Always wear the appropriate protective equipment, such as safety
glasses and gloves.
• Always use safety blocks under any load being lifted with the tool,
where possible. See fi gures 3 & 4.
• Never place any body part between the tool and the equipment being
worked on.
• Creating pressure beyond the 10,000 psi rated capacity may result in
injury.
Safety Block Benefi ts
• Multi-Step Design: Each safety block has three
steps - 1”, 2”, & 3”, which allows the operator to
choose the width of fl ange separation.
• Light Weight with Easy Grip Handle: Allows the
operator to easily grip the safety block, even when
wearing gloves.
• Secure Support: After the Auto-Spreader opens
Figure 3
the fl ange, safety blocks are inserted in the gap
between the fl anges. The fl ange spreaders are then
closed to transfer the load to the safety blocks, enabling the operator to work more safely on the gasket
surfaces.

Maintenance
Treat the Auto-Spreader like any other precision tool. Keep it clean and
free from moisture. Simply wipe it down with a cloth or paper towel after
use.
If there is damage, due to improper storage or unusual circumstances,
contact Fastorq for handling instructions.
All internal parts are lubricated at the factory and do not need cleaning or
re-lubrication.
All the materials used in the Auto-Spreader were chosen through extensive research. All parts are rated for their intended use, and do not need
fi eld repair. Improper assembly, modifi cation or substitution of other parts
is unsafe, will void the warranty and could damage the tool.
Foot Replacement Kit
After extended usage, the feet may need replacement. These are the
only parts which are fi eld replaceable. Call 1-800-231-1075 for the AutoSpreader foot replacement kit, refer to part #RKCF for the center foot kit
or part #RKOF for the outside feet kit.

Foot Replacement
When it is necessary to replace a foot on the Auto-Spreader follow these
steps:
1. Close the feet. The center foot (6) should be aligned with the outside
feet (2 and 3). See fi gures 5 and 6.
2. Loosen the two fl at head Allen screws (1,4) on the bottom of the foot
being replaced.
3. Remove old foot and position new foot in its place.
4. Tighten the two fl at head Allen screws.
Note: It is very important that the fl at head Allen screw be properly tightened. The required torque value is 40 ft. lbs.
Tool Storage
1. Wipe the tool clean with a cloth or paper towel.
2. Close the feet.
Note: The Auto-Spreader should be kept in the ready position when not
in use; feet closed. See fi gure 5.

Assembly/Disassembly Instructions
The Auto-Spreader™ HS10K is delivered assembled and ready to use.
If it is necessary to disassemble the Auto-Spreader for repairs, follow
the assembly instructions carefully when re-assembling. Failure to follow
these instructions may damage one or more of the components. If any
of the Auto-Spreader components are damaged, please contact your
Fastorq representative before re-assembly.
Disassembly Instructions
All numbers in parentheses are referenced in fi gure 6 and the Parts List
on page 7.
Should it become necessary to disassemble the Auto-Spreader, follow
these steps:
Note: Before disassembling the tool, mark the position of the cylinder in
reference to the housing.
1. Close the feet by retracting the center foot until it is aligned with the
outside feet.
2. Position the Auto-Spreader on its side. The side with the dowel pin (7
) should be facing up.
3. Insert a socket head cap screw or any hardened screw with #8-32
threads and about 2” long in the hole and screw it in the dowel pin inside
the hole.

4. Engage the screw using a pry bar and pull it out 1/2”. The dowel pin
should come out along with the screw.
5. Extend the cylinder to the maximum extension mark on the piston (6).
6. Pressurize the cylinder to 2,000 PSI or so.
7. Turn the sub-assembly counter-clockwise until it is completely unscrewed and slides out easily. The sub-assembly consists of the adapter
(10), piston (5) and the center foot (7).
8. Release the pressure to retract the cylinder and disconnect the cylinder from the pump.
9. Loosen the set screw in the front of the housing with a 5/36” Allen
wrench. Remove the cylinder (11) by turning it counter-clockwise.
Assembly Instructions
1. Review the Parts List and verify that all the parts are available and in
good order.
2. Clean all the parts with a de-greasing solvent.
3. Screw the cylinder (11) all the way onto the housing (8).
4. Position the outside feet (2 and 3) against the bottom of the housing
(8). Be sure to place the feet, which are marked (L) and (R), on the appropriate sides of the housing. The countersunk screw holes should be
facing out, and not against the bottom of the housing (8).
5. Insert the fl at head Allen screws (1) in the screw holes on the outside
feet, and tighten them with a 5/16" Allen wrench to 35-40 Ft lis.
6. Place the center foot (5) on top of the piston. The countersunk screw
holes will be facing up. See fi gure 7.

7. Insert the fl at head Allen screws (4) in the screw holes on the center
foot, and tighten them with a 1/4" Allen wrench to 25-30 ft. lbs.
8. Screw the adapter (10) into the piston (6) all the way until the shoulder
on the adapter touches the top of the piston. Torque to approximately 35
ft. lbs. Note: The adapter has left hand threads.
9. Lightly lubricate the outside of the piston (6) with
Fastorq A/G (70% solid lubricant), which can be purchased from Fastorq.
10. Connect the hydraulic cylinder to a pump through the quick disconnect
attached to the cylinder. Use 10,000 PSI
W.P. rated hydraulic hose. Extend the cylinder by pressurizing the pump.
Maintain full pressure on the cylinder while executing step 11.
11. Insert the sub-assembly in the housing (8). The
sub-assembly consists of the center foot (5), piston (6), adapter (10).
Screw the assembly clockwise into the front of the piston rod, until the
adapter stops against the
cylinder rod.

12. Release the hydraulic pressure from the cylinder and the center foot
will retract.
13. Install the dowel pin (7) in the hole on the side of the housing (8),
use a hammer if necessary. The dowel pin will ride in the slot on the side
of the piston (6), if everything is properly assembled.
14. Check the feet again to be sure they are still aligned. Check the
alignment of the cylinder in reference to the housing (this should have
been marked in disassembly). Insert the set screw (9) in the hole provided in the front of the housing (8). Tighten the set screw to the cylinder.
Do not tighten the set screw too tight, or future removal of the cylinder
may be diffi cult.
15. Pressurize and de-pressurize the cylinder to check that the tool is
operating properly.
Trouble Shooting
General Notes:
- Do not twist or bend hoses too sharply.
- Pay close attention to keeping all parts clean internally
and externally. (Dirt and foreign matter are the most
common causes of trouble in hydraulic systems)
- Make sure all quick couplers are always completely
coupled together.
