CLEANING SPIRAL CUTTERHEAD & TIPS (cont.)
Step 3 - Separate the tips from the screws and place in separate containers with a bit of mineral
spirits or non-chlorinated brake cleaner. Once all are removed, wipe down the bare cutterhead
using rags with whichever solvent you chose. Once the oil is wiped off, use an air compressor or a
can of pressurized air to clear each seat and screw hole on the cutter head. This will aid in knife
and cutter tips reinstallation.
Step 4 - Lubricate the Torx screw threads with light machine oil, wipe the excess oil off the threads,
Place each knife in the seat and slightly snug each screw using the Hex Wrench to hold the
cutterhead in position. Once you get a row of tips seated and slightly tightened down, repeat by
going back over each cutter tip and tighten down the screws securely to 48 to 50 inch / lbs.
REINSTALL THE CUTTERHEAD GUARD ASSEMBLY Grasp the guard mounting bracket in
your right hand and pull back on the red cover with your left hand to set proper spring tension.
While holding in this position, place bracket over the 2 screws and slide the guard assembly down.
Tighten the 2 bracket screws. Use FIG 10 and FIG 11 on page 18 for reference if necessary.
After all assembly and adjustment instructions are completed, use a sacrificial board after cleaning
to test for remaining oil. If oil is still apparent, repeat the cleaning method you used above.
