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
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

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.
