the lock washers and flat w ashers.
11. Do not operate the unit without the deflector in place .
12. Before stopping the chipper, be sure the all of the material is out of the head and out
of the feed roll.
13. All of the material in the chute must be gone or the unit could jam on a small piece of
material. This can usually be cleared by turning the unit backwa rds by hand.
14. To replace the blades, take the PTO shaft out of ge ar, then turn off the tractor. The
blades on mos t models are replac ed or turned by removing the insp ection plate on
the side opposite the chute.
15. Unhook the feed roll sprin gs, block the fe ed roll to maximum position, and , with an
Allen wrenc h on th e chute side and a socket on the other, remove the bolts. (Be
careful not to drop any pa rt inside.)
16. Remove th e blade, clean the blade pocket and turn or s harpen the blade. Replace
blade.
17. Torque the bolts to 50 ft.-lbs. in al l holes so the bolts are straight through the
flywheel. A small screwd river or ice pick wo rks well to clean pocke ts for the Allen
wrench. Replace the inspec tion plate and reattach the springs.
18. Turn over by hand before applying power.
19. The cutte r bar should be adjusted to 0.010 to 0.03 0" from the blades by loose ning
the bolts in the bottom of the chute in the slotted holes and movi ng the bar on slots.
20. Bolts are to be tor qued to 35 ft.-lbs.
21. The cutter bar can be reversed and/or resharpened.
22. Dull blades caus e many problems, such as: Seeming lack of power, plugging of the
discharge chute, rough cutting wi th more vibration than usual, feed roll shaft brok en,
main bearing housing broken, main bearing wo rking loose and the flywheel or
blades hitting the case or bed knife, feed roll kicking out of gear, and not feeding.
