Inspect/Sharpen Chipping Knives
The unit’s high-quality chipping knives are manufactured
from a high-quality precision tempered steel, and are
designed to provide positive feeding of tree limbs and
branches, as well as exceptionally long service life.
Normal chipping operations will gradually wear the
cutting edges of these blades, but the rugged design
and tough material used allows them to be quickly and
easily resharpened for long-lasting, like-new
performance.
When tree limbs and branched begin to require
additional pressure to feed into the chipping knives, it
may be time to sharpen the cutting edges to return them
to their original performance.
Sharpening the cutting knives requires the following
major steps:
1. Disconnect spark plug wire.
2. Removal of the shredder hopper.
3. Removal of the chipper cone.
4. Removal of the access plug.
5. Removal of the cutting knives.
6. Careful, low-speed, wet grinding of a new edge.
7. Reassembly of the cutting knives to the oval chipping
block.
8. Reassembly of the chipper cone and shredder hopper
to the unit.
Consult the troubleshooting and repair section of this
manual for complete disassembly, inspection, and
replacement instructions.

Lubricate Wheel Axles
The low profile and excellent balance of the unit makes
transporting it easy, but constant exposure to dirt,
debris, and chipper/shredder materials requires routine
lubrication of the wheels.
To lubricate, squirt 3-5 drops of engine oil on each wheel
axle. Wipe up any runoff and spin wheels briefly to work
oil around entire axle.
Check Safety Labels
The safety labels located in various positions on the
shipper/shredder have been place to help remind you of
important safety rules while you are running the chipper/
shredder unit.
While these labels are extremely durable, constant
abrasion from tree limbs and branches can eventually
affect their readability. Check each label to make sure it
is still properly affixed to the chipper/shredder, and is
still completely legible.
If any label can’t be read, contact your local dealer for
an immediate replacement. If you must use the unit
without the label, review the label information in the
“safety labels” section of this manual.
Clean Engine Fins/Air Intake Area
See the engine service manual shipped with your
chipper/shredder for additional information.
To clean the air intake area remove any chipper/
shredder build up, and then blow out the area using a
stream of compressed air. If a compressor is not
available, use a stiff bristle parts brush, which is
available at most auto parts supply stores.
To clean the cooling fins, brush the area between the
fins with a stiff bristle parts brush, and blow out any
remaining debris with a stream of compressed air. If the
cooling fins are caked with an oily build-up of chipper/
shredder debris, using a commerically available engine
cleaning aerosol may help loosen and remove the
deposits.
If you use such a cleaning product, you must follow all
safety and use instructions to prevent damage to the
engine components and personal injury to you.
Using a stream of water to clean the engine requires
immediate drying of engine components to prevent
rusting and possible malfunctioning of the engine’s
electrical system.
