Clean Engine Fins/Air Intake Area
The engine that powers this chipper/shredder is air-
cooled, and requires unobstructed air flow into and
around the engine. For proper engine cooling, the cool-
ing fins on the engine cylinder head area must also be
kept clear of chipper/shredder deposits, as well as any
other build-up of debris that could prevent heat from radi-
ating away from the engine.
To clean the air intake area, remove any chipper/shred-
der 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 commercially 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 rust-
ing and possible malfunctioning of the engine’s electrical
system.
Clean/Oil/Replace Air Filter Element
The engine air filter element filters and removes airborne
dirt, dust, and other work site debris from the air before it
can enter the carburetor and damage sensitive fuel pas-
sages.
Depending on the type of air filter element installed on
your chipper/shredder engine, you should periodically
perform one of the following steps:
• clean and oil the air filter (foam filter only),
• only clean the air filter (Type “A” filter),
• or replace the filter every year or 100 hours of opera-
tion (paper filter element).
Consult the engine manufacturer’s manual provided with
your chipper/shredder for the specific instructions that
apply to your unit.
If you have any doubts about what type of filter element
you have, consult you local authorized dealer for help in
replacing or ordering the correct element.

Inspect/Rotate Shredding Hammers
The patented shredding hammers on this line of chip-
per/shredders can be easily rotated to provide new cut-
ting surfaces as required.
Triangular hammers can be rotated twice, then flipped
over for a total of six sharp, new leading edges. “J” ham-
mers on the Model 5/14 can be flipped over once, for a
total of two sharp, new leading edges.
If the shredding action of the unit seems sluggish, or you
notice that shredded material is not shredded as thor-
oughly as when the unit was new, the shredding ham-
mers may need to be rotated or replaced.
Rotating the shredder hammers requires the following
major steps:
1. Removal of the shredder hopper.
2. Removal of the rotor housing.
3. Removal, rotation, and/or replacement of the shred-
der hammers.
4. Replacement of the rotor housing.
5. Replacement of the shredder hopper.
Consult the Troubleshooting and Repair Section of this
manual for complete disassembly, inspection, and
replacement instructions.
Your local authorized dealer can provide this service to
you if you do not wish to disassemble the unit and
inspect/repair it yourself.
