MAINTENANCE & SERVICE
SHARPENING BLADES CONTINUED…
4) Grind the angled edge of the chipping blade at 33 degrees (see below picture) using
a slow wet grinder or have them sharpened by a professional. A bench style grinder
can yield poor results if not used properly. If sharpened to quickly or aggressively on
a bench grinder, the blade edge can get hot and begin to change colour. This
indicates overheating and will remove the heat treat properties of the blade. Use
short grinding times and cool with water. Remove an equal and consistent amount of
material from each blade to maintain proper balance.
Chipper Blade
5) Re-install the sharpened blades on the flywheel and torque the bolts to 40-45 ft-lbs
(54-60N-m) . Always replace the nuts and bolts with new hardware when changing
blades or reversing the blades.
SETTING BED PLATE GAP
The bed plate (also known as the “anvil plate”) is located at the flywheel housing on the left
side of the infeed chute (when standing at the back of the chipper). The gap between it and
the chipping blades should be set to 1/16”-1/8” (1.5mm-3mm) . Follow the below steps to
set the gap properly. Failure to set the proper gap can cause poor chipping performance
and/or clogging.
1) If installed, the PTO shaft should be disconnected from the tractor for safety.
2) The upper flywheel housing can be opened to access the blades by using a 24mm
wrench to remove the bolt holding the two halves together.
