5.4 CHIPPER BLADES MAINTENANCE
The chipper blades will eventually become dull, making
chipping difficult and adding extra strain on the machine.
CHECK THE SHARPNESS OF THE BLADES EVERY
5-15 HOURS OF OPERATION AND SHARPEN AS
NEEDED.
Your blades need to be sharpened if:
●
Machine vibrates severely when material is fed into
the chipper.
●
Chips discharge unevenly or have stringy tails,
especially when chipping green branches.
Before you sharpen the chipping blades, check for
permanent damage. Replace the blade if:
●
There are cracks, broken corners or nicks greater
than 1/8" (see below).
●
The base of the cutting edge is worn or has been
re-sharpened so that it no longer extends past the
chipping slot (see below).
