POWER REQUIREMENTS
The BVA Nut Splitter is hydraulically driven. All models require a hydraulic pump that delivers 10,000 PSI
pressure. Exceeding 10,000 PSI pressure will void any and all warranties. Any type of hydraulic pump may
be used to operate the BVA Nut Splitter; including air, electric, foot driven, or hand pumps. Pumps can
be purchased seperaely from BVA and include all the necessary hoses and ttings. See the list below for
appropriate pump and Nut Splitter combinations.

ASSEMBLY
Within the BVA Nut Splitter there are three "Model" types; the Straight Head
Models, Angle Head Models, and Angle Head Double Cutting Models. All three
models share similar features of assembly, but between the three models there
are two di󰀨erent methods of holding the cutting chisels. See illustration below.
Type 1 Type 2
The assembly instructions are seperated based on the chisel holder
types. Section 1 assembly shall cover all assemblies involving the "Type
1" chisel holder and section 2 shall cover all assemblies involving the
"Type 2" chisel holder.

1. Unscrew the chisel holder from the cylinder.
2. Place the knobbed end of the cutting chisel into the center hold of the chisel holder.
3. Insert the set screw into the threaded side hole of the chisel holder. Do not over
tighten the set screw, it is provided to hold the cutting chisel inside the chisel holder
only. The cutting chisel should be loose enough to spin with minimal friction inside the
chisel holder, but not fall out.
4. Place the appropriate space for the nut you are cutting inside the cylinder. The spacer
shall be placed inside the cylinder in such a way that engraved side can be read.
Only one spacer is required to split a nut. Never split a nut with more than one spacer
installed at a time, doing so will damage the stud threads.
5. Screw the chisel holder and chisel assembly (from step 3) into the cylinder until it is
seated rmly and bottomed out in the cylinder.
6. Connect the cylinder and pump together via 10,000 PSI hydraulic hose.
7. Pressure up the cylinder until the internal piston has been fully extended from the
cylinder. Hold the pressure so that the piston stays in this extended positon.
8. Place the BVA Nut Splitter housing on the threaded end of the cylinder and screw the
housing onto the cylinder. Screw the housing all the way onto the cylinder until it is
seated rmly and bottomed out on the cylinder, unscrew the housing one full turn.
9. Insert the set screw into the threaded side hole of the housing and tighten to secure it
into place.
10. Release the held pressure on the cylinder to allow the piston to retract back into the
cylinder.
11. Your BVA Nut Splitter is now fully assembled and ready for use.

1. Unbolt the chisel holder from the cylinder.
2. Place the knobbed end of the cutting chisel into the center hold of the chisel holder.
3. Insert the set screw into the threaded side hole of the chisel holder. Do not over
tighten the set screw, it is provided to hold the cutting chisel inside the chisel holder
only. The cutting chisel should be loose enough to spin with minimal friction inside the
chisel holder, but not fall out.
4. Place the appropriate space for the nut you are cutting inside the cylinder. The spacer
shall be placed inside the cylinder in such a way that engraved side can be read.
Only one spacer is required to split a nut. Never split a nut with more than one spacer
installed at a time, doing so will damage the stud threads.
5. Align the two bolt holes of the chisel holder and spacer assembly (from step 3) to the
two threaded holes on the top of the piston on the cylinder, and screw in the two bolts
removed from step 1. Tighten the two bolts until they are seated rmly in the cylinder.
Some of the BVA Nut Splitter models are packaged with two sets of bolts; this is to
accomdate thicker spacers. If during assembly it is discovered that the two bolts are
too short, use the the longer second set to rmly bolt the chisel holder assembly and
spacer into the cylinder.
6. Connect the cylinder and pump together via a 10,000 PSI hydraulic hose.
7. Pressure up the cylinder until the internal piston stays in this extended position.
8. Place the BVA Nut Splitter housing on the threaded end of the cylinder and screw the
housing onto the cylinder all the way until it is seated rmly and bottomed out on the
cylinder. Once the housing has been rmly seated and bottomed out, unscrew the
housing one full turn.
9. Insert the set screw into the threaded side hole of the housing and tighten it to secure
it into place.
10. Release the held pressure on the cylinder to allow the piston to retract back into the
cylinder.
11. Your BVA Nut Splitter is now fully assembled and ready for use.

OPERATION
*Before operation read and follow all warnings, safety tips and assembly instructions.
1. Lubricate the cutting edge of the chisel with an anti-seize lubricant before each split is
attempted.
2. Place the BVA Nut Splitter over the but to be split. Orientate the BVA Nut Splitter in the
exact position as illustrated below. The BVA Nut Splitter should be parallel to the surface of the
ange, and the cutting chisel should be centered on the at side of the nut being split. Refer to
the illustration below for proper alignment.
3. Pressurize the cylinder to extend the chisel slowly until the cutting edge makes
contact with the at nut face. Verify that the cutting edge is centered on the at
of the nut before continuing.

4. Continue to pressurize the cylinder slowly to begin splitting the nut. You will hear a loud
pop; this noise indicates that the but has been successfully split. Once you hear the loud
pop, stop pressurizing the cylinder.
5. If the nut was frozen in place, it should now be freed enough to rotate the nut 180 de-
grees to split the opposite at on the nut for complete removal. If the nut cannot be ro-
tated, reorient the BVA Nut Splitter itself instead and repeat steps 1 through 4.
6. Having two opposite ats faces of the nut successfully split, the nut should now be in two
pieces and can easily be removed from the stud.
A successfully split nut should look like the illustration below.

Maintenance
The BVA Nut Splitter is designed to be a low maintenance tool. Following the steps below will
help ensure a long useful shelf life of the tool for years to come.
* Always lubricate the cutting edge of the chisel with an anti-seize lubricant before each slpit
it attempted. Grease and molly based lubricant is recommended and can be purchased
seperately.
*Do not let the cutting chisel get dull. The cutting chisel can be re-sharpened by hand with a
whestone or on a bench grinder using a slow rpm and a ne ground wheel. Keeping the
cutting chisel well lubricated and cool during sharpening will allow you to sharpen the cut-
ting edge quickly and safely.
* After each use thoroughly clean the tool and its accessories before storage.
* Replace all thread protectors and dust covers on the tool when not in use or during stor-
age. This will help keep any debris from entering the hydraulic system and keep the oil
clean and ready for use.
* For storage, always keep your BVA Nut Splitter in its supplied tool box. The supplied tool
boxes have been manufactured to keep the tool and its accessories safe from any acci-
dental damage and will increase the longevity of the tool.
