Maintenance

General Recommendations

• Always observe safety rules when performing any maintenance.

•

•

•

The warranty on this lawn mower does not cover items that have been subjected to operator abuse or negligence. To receive full value from warranty, operator must maintain the lawn mower as instructed here.

Changing of engine-governed speed will void engine warranty.

All adjustments should be checked at least once each season.

• Periodically check all fasteners and make sure these are tight.

WARNING: Always stop engine, disconnect spark plug, and ground against engine before performing any type of maintenance on your machine.

Lubrication

1. Lubricate pivot points on the blade control at least once a season with light oil. This control must operate freely in both directions. See Fig. 6-1.

2.

3.

Lubricate the wheels at least once a season with light oil (or motor oil). If wheels are removed for any reason, lubricate surface of the axle bolt and inner surface of the wheel with light oil. See Fig. 6-1.

Follow the accompanying engine manual for lubrication schedule and instruction for engine lubrication.

Deck Care

Clean underside of the mower deck after each use to prevent build-up of grass clippings or other debris. Follow steps below for this job.

1.

2.

Disconnect spark plug wire. Drain gasoline from lawn mower or place a piece of plastic under the gas cap.

Tip mower so that it rests on the housing. Keep the side with the air cleaner facing up. Hold mower firmly.

WARNING: Never tip the mower more than 90º in any direction and do not leave the mower tipped for any length of time. Oil can drain into the upper part of the engine causing a starting problem.

3. Scrape and clean the underside of the deck with a suitable tool. Do not spray with water.

IMPORTANT: Do not use a pressure washer or garden hose to clean your unit. These may cause damage to the engine.

The use of water will result in shortened life and reduce serviceability.

4. Put the mower back on its wheels on the ground. If you had put plastic under the gas cap earlier, make sure to remove it now.

•

•

Maintain oil level as instructed in engine manual.

Service air cleaner every 25 hours under normal conditions.

Clean every few hours under extremely dusty conditions.

Poor engine performance and flooding usually indicates that the air cleaner should be serviced. To service the air cleaner, refer to the engine manual.

Clean engine regularly with a cloth or brush. Keep the top of the engine clean to permit proper air circulation.
