Daily Maintenance

WARNING!

To reduce fire hazard, keep the engine and muffler free of dirt, debris, and leaves.

Prior to each workday, perform the following:

■■Remove all dirt and debris from blower exterior and the engine. Check the cooling fins and air cleaner for clogging and clean as necessary.

CAUTION!

The engine is cooled by air drawn into the air intake cover on the blower housing. The blower fan then pushes the cooling air through an opening in the fan housing, forcing it past the cylinder cooling fins. Failure to keep the cooling system and its passages clear of debris will likely result in engine overheating, a major cause of serious engine problems that can lead to failure.

■■Inspect the engine, tank, and hoses for possible fuel leaks, and repair as necessary.

■■Inspect the entire blower for loose, damaged, or missing components, and repair as necessary.

■■Carefully remove any accumula- tions of dirt or debris from the muffler and fuel tank. Dirt build-up in these areas can lead to engine overheating, fire or premature wear.

Air Cleaner

1. Remove the air cleaner cover by

loosening the thumbscrews and lift-

ing. See Figure 19.

2. Remove and inspect the pre-filter.

If the pre-filter is torn or otherwise

damaged, replace it with a new one.

IMPORTANT!

The blower uses a special high capac- ity dry-type air filter element. The filter should not be cleaned with a liquid cleaner and must NEVER be oiled!

Pre-Filter

Thumbscrews

To remove the cover, loosen the

thumbscrews and lift.

Figure 19

3.Clean the pre-filter with soap and water. Let dry before reinstalling.

4.Inspect the air cleaner element. If the element is damaged or distorted, replace it with a new one.

5.Tap filter gently on a hard surface to dislodge debris from element or use compressed air from the inside to blow debris out and away from the air filter element.

6.Install the filter element, pre-filter and cover in the reverse order of removal.

IMPORTANT!

Direct the air stream at the inside face of the filter only!

CAUTION!

Never operate the blower if the air

cleaner assembly is damaged or

missing!

Every 10/15 Hours

CAUTION!

Never allow dirt or debris to enter the cylinder bore! Before removing the spark plug, thoroughly clean the spark plug and cylinder head area!

Allow the engine to cool before servicing the spark plug! Cylinder threads can be damaged by tighten- ing or loosening the spark plug while the engine is hot!

■■Replace the spark plug annually: Use only NGK CMR5H or equivalent resistor type spark plug of the cor- rect heat range. Set spark plug elec- trode gap to 0.6 mm (0.024 inch).

1.Use the spark plug wrench to remove the spark plug. (See Figure 20)

2.Clean and adjust the spark plug gap to 0.6mm (0.024”). If the plug must be replaced, use a NGK CMR5H or equivalent type plug of the correct heat range.

3.Install the spark plug finger-tight in the cylinder head, then tighten it firmly with the spark plug wrench. If a torque wrench is available, torque the spark plug to 16.7-18.6 Nm

(148-165 inch- pounds).
