BXS Series
3PH Self-feed Chipper
36
8.6 Rotor Blades
Check rotor blade sharpness daily.
If the chipper is not pulling the material or material has to
pushed into the chipper, the rotor blades are probably dull.
Reverse or sharpen the blades if the cutting edge becomes dull.
Check blade sharpness more often if processing material with a
lot of sand, soil or dirt in it.
Keeping the blades sharp reduces the amount of power required
during operation.
Sharpening Rotor Blades
1.
Remove the blades from the rotor to sharpen. Sharpen at a
45° angle to provide the best cutting effect.
IMPORTANT! Make sure equal amount of material is
removed from each blade when sharpening to maintain
proper rotor balance.
CAUTION!
Risk of getting hands pinched or wedged
between lower rotor housing and rotor. Turn
rotor slowly and be aware of hand positioning.

2.
Install rotor blades with leading edge out, towards the
ledger blade. Tighten the blade mounting bolts.

8.7 Ledger Knife
Observe ledger knife performance daily. Check the ledger
knife sharpness every 50 hours.
The ledger knife is bolted inside the lower rotor housing
assembly. As the rotor turns, material fed into the chipper is
sheared off at the ledger knife by the rotor blades.
When the corner of the ledger knife facing the rotor blade rounds
over, the blade can be removed and re-installed with a different
corner facing the rotor blade. Once all four corners have been
rounded, remove the knife to sharpen or replace it.

To obtain the best chipper performance, check the clearance
between the rotor blade and stationary ledger blade every 50
hours.
