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 firmly 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 firmly 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 firmly and bottomed out on the
cylinder. Once the housing has been firmly 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.
