5 INCH CHIPPER/SHREDDER/BLOWER
SERVICE & MAINTENANCE
WARNING
BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE,
AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.
1. Loosen and remove the 3/8" carriage bolt securing
the knife access cover.
2. Open the access cover exposing the chipper shredder
compartment.
3. Rotate the rotor so that the bolts holding the chipper
blade are most accessible.
4. Remove the two hex head bolts holding the blade
itself. Repeat for the second blade. The chipping
blades have two edges per blade and can be reversed
one time each before sharpening. If one side has not
been used, remove and reverse the chipping blades.
Chipping blades are sharp! Use caution when working
on machine to avoid injury.
WARNING
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 blades can be ground on a bench grinder or by a
professional.
1. Never sharpen or grind the mounting surfaces of
the blades. This will cause the edge to roll and the
blade will be damaged, resulting in poor chipping
performance.
2. Regrind the angled edge of the chopping blades to
45 degrees (Figure 5.1). Use the blade angle gauge
plate when sharpening the blades to achieve the
proper angle (see Figure 5.2).
5.2 ROTOR LOCK
There are holes on the rotor that are utilized to lock
the rotor in place before performing any kind of service
and/or maintenance.
Follow the steps below to lock the rotor:
1. Insert bolt through hole on rotor and rotate the rotor
until the bolt rests on the housing, preventing the
rotor from moving.
2. Remove bolt when service and/or maintenance is
completed.
The rotor assembly has a lock mechanism. When
working on the rotor assembly, use the lock mechanism
at all times.
WARNING
●
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).
