Adjusting Carburetor

To adjust the drive clutch, rotate the adjustment wheel with your fingers. You should rotate the wheel clockwise to tighten the cable and counter-clockwise to loosen the cable. See Figure 16.

If the drive clutch control handle is not in a comfortable position for you, adjust the handle by tightening the adjustment wheel. See Figure 16.

Adjusting Carburetor

If the engine is running rough, minor adjustments to the carburetor may be required to compensate for differences in fuel, temperature, altitude and load.

NOTE: A dirty air cleaner may cause an engine to run rough too. So make sure that the air cleaner is clean and attached to the carburetor before deciding to adjust the carburetor.

To adjust the carburetor, please follow the recommendations and instructions on carburetor adjustment in the engine manual.

WARNING: If any adjustments are made to the engine (e.g. carburetor) while the engine is running, keep clear of all moving parts. Be careful of heated surfaces like the muffler.

SECTION 11: LUBRICATION

WARNING: Always stop engine and disconnect spark plug wire before cleaning, lubricating or performing any kind of work on your lawn mower.

For complete lubrication chart, see Figure 17.

Wheels: The wheels require no lubrication. However, if the wheels are removed for any reason, lubricate the surface of the axle bolt and the inner surface of the wheel with light oil or engine oil.

Chute Deflector: Lubricate the torsion spring and the pivot point on each end of the chute deflector using a light oil. This will prevent rusting and ensure that the deflector, which is a safety device, can always work properly.

Engine: Follow the engine manual instructions and recommended schedule for lubricating engine components.

Pivot Points: Lubricate the pivot points on the blade control handle, brake cable and the cutting height adjustment lever at least once a season with light oil. The blade control handle must operate freely in both directions. The cutting height adjustment lever should be able to move easily.
