Clean Engine Air Intake Area

The engine is air-cooled, and requires unobstructed air flow into and around the engine. The cooling fins on the engine cylinder head area must also be kept clear of chipper and shredding deposits, as well as any other build-up of debris that could prevent heat from radiating away from the engine (Figure 14).

To clean the air intake area, remove any external materi- al 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 debris, using a commercially available engine cleaner aerosol may help loosen and remove the deposits. If you use such a product, you must follow all safety and use instructions to prevent damage to the engine compo- nents 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 electrical system. If a water stream is used to clean debris, start the engine immediately, and allow engine heat to speed drying.

The recoil starter rope and handle should be inspected for signs of abrasion or wear that could result in breakage.

Inspect Chipper Cone

Check the cone to make sure that it hasn’t been dam- aged or worn excessively by constant use, and replace it if it is cracked, worn out, or no longer fits securely on the chipper cone mounting flange.

Cracks, worn areas, and loose attachment points can cause material to jam or clog when feeding it into the machine, and may result in kick-back or other hazard to the operator.

Contact your local dealer for replacement parts if your unit shows any evidence of these problems, and discon- tinue use of the unit until the appropriate repairs can be made .

Check Safety Labels

The safety labels located in various positions on the Chipper Vacuum have been placed to help remind you of important safety rules while you are operating or transporting the Chipper Vacuum unit.

If any label can’t be read or is missing, contact your local dealer for an immediate replacement. If you must use the unit without the label, review the label informa- tion in the “Safety Decals” section of this manual.

Lubricate Wheels, Pulleys, and Sprockets

To lubricate, squirt 3-5 drops of SAE 30 oil on each wheel axle at the wheel bearings, and at each bearing on the pulleys and sprockets. Wipe up any run-off and spin wheels briefly to work oil around entire axle

Inspect Vacuum Nozzle Housing

Check the vacuum nozzle housing for build-up of debris,
