5.4 The Blade and Counter Blade maintenance
• Routine inspection of the Chipper Blade and counter blade will ensure that your PTO
Chipper is operating at full efficiency. Operating with a worn or damaged Chipper Blade or
Counter blade will cause extreme stress and vibration to the machine and make chipping
difficult for the operator.
• Routinely check the chipper blade for sharpness. Using a dull blade will decrease
performance and cause excessive vibration that will cause damage to the chipper.
• Routinely check the distance between blade and counter blade. Wrong distance will
decrease performance and cause excessive vibration that will cause damage to the PTO
chipper.
• Disengage PTO, shut down the tractor engine, remove the key, wait for all moving parts to
come to a complete stop, disconnect the PTO shaft from the tractor, then wait 5 minutes
before performing any maintenance procedure or inspection on the chipper.
• If the rotor surface is not cleaned properly and the chipper blade is not mounted flush on
the rotor, the blade could crack when the hardware is tightened.
• Be careful and wear gloves when working near the chipper blade. The blade edge can cut
you if you come in contact with it.
•
The torque of Blade bolts is around 60-70NM
•
Fix the bolts from centre one to both sides evenly.
1. Remove the conveyor and hopper.
