Refer to the manual for specific oil and fuel capacities.

Operation Instructions
Properly starting‚ adjusting cutting heights‚ and employing effective mowing techniques are crucial for optimal performance with your Cheetah 127cc lawn mower.
Starting the Engine
Before attempting to start your Cheetah 16 127cc lawn mower‚ ensure the fuel tank is filled with fresh gasoline and the oil level is correct. Confirm the blade is properly attached and the safety bail is engaged.
Prime the engine by pressing the primer bulb several times until fuel is visible. Slowly pull the starter cord with a firm‚ steady motion. Avoid rapid or jerky pulls. If the engine doesn’t start after a few attempts‚ allow the engine to cool before trying again.
Always start the mower on a level surface and keep bystanders clear. Never start or operate the mower indoors or in a poorly ventilated area. Inspect the spark plug and air filter if starting issues persist.
Remember to disengage the blade before storing or transporting the mower.
Adjusting Cutting Height
The Cheetah 16 127cc lawn mower offers adjustable cutting heights to accommodate various lawn conditions. Locate the cutting height adjustment levers‚ typically found on each wheel. These levers control the distance between the blade and the ground.
To raise the cutting height‚ move the levers towards the higher setting. To lower the height‚ move them towards the lower setting. Ensure all four wheels are set to the same height for an even cut.
Start with a higher setting and gradually lower it until you achieve your desired grass length. Avoid cutting more than one-third of the grass blade length at a time to prevent stressing the lawn. Regular adjustments ensure a healthy and well-maintained lawn.
Mowing Techniques
For optimal results with your Cheetah 16 127cc lawn mower‚ overlap each mowing pass by a few inches. This prevents scalping and ensures a consistent cut. Maintain a steady walking pace; avoid rushing‚ as it can compromise the quality of the cut.
When mowing tall grass‚ raise the cutting height and make multiple passes‚ gradually lowering the height with each pass. This reduces strain on the engine and prevents clogging.
Always mow in a straight line‚ turning when you reach the end of the lawn. Consider mowing in alternating directions each time to promote even growth. Empty the grass catcher bag frequently to maintain efficient operation.

Maintenance and Care
Regular upkeep‚ including air filter checks and blade sharpening‚ is crucial for the Cheetah 127cc lawn mower’s longevity and peak performance.
Follow the schedule for optimal results.
Regular Maintenance Schedule

Maintaining your Cheetah 16 127cc lawn mower involves a consistent schedule to ensure reliable operation. After each use‚ inspect the blade for damage and clean the mower deck‚ removing grass clippings.
Every 25 hours of operation‚ check the air filter and clean or replace it as needed; also‚ inspect the spark plug. Every 50 hours‚ change the engine oil – using the correct grade is vital.
Annually‚ sharpen or replace the blade‚ and thoroughly inspect all fasteners for tightness. Regularly check fuel lines for cracks or leaks. Proper maintenance extends the life of your mower and keeps it running smoothly. Refer to the parts manual for component locations.
Air Filter Cleaning/Replacement
The air filter on your Cheetah 16 127cc lawn mower is crucial for engine performance. Regularly inspect the filter – typically every 25 hours of use – for dirt and debris accumulation. A clogged filter restricts airflow‚ reducing power and increasing fuel consumption.
For cleaning‚ gently tap the filter to remove loose dirt‚ or use compressed air‚ blowing from the inside out. If the filter is excessively dirty or damaged‚ replace it with a new one.
Ensure the new filter is properly seated to prevent unfiltered air from entering the engine. Refer to the parts list for the correct filter part number. Maintaining a clean air filter optimizes engine efficiency and prolongs its lifespan.
Blade Sharpening and Replacement
Maintaining a sharp blade is essential for a clean cut and healthy lawn. Regularly inspect the blade on your Cheetah 16 127cc mower for dullness or damage. A dull blade tears grass‚ causing it to brown and become susceptible to disease.
Sharpen the blade using a metal file or a blade sharpening tool‚ ensuring the angle is consistent. If the blade is severely damaged‚ bent‚ or cracked‚ replace it immediately.
Always disconnect the spark plug wire before working on the blade. When installing a new blade‚ ensure it’s securely fastened with the correct torque. Refer to the parts list for the appropriate blade part number and follow safety guidelines.

Troubleshooting Common Issues
This section addresses frequent problems with the Cheetah 16 127cc mower‚ including engine starting failures‚ uneven cuts‚ and excessive vibrations‚ offering solutions.
Engine Won’t Start
If the engine fails to start‚ first verify the fuel tank contains fresh gasoline and the fuel shut-off valve (if equipped) is open. Check the spark plug; ensure it’s clean‚ properly gapped‚ and securely connected. A fouled or damaged spark plug will prevent ignition.
Confirm the air filter is clean; a clogged filter restricts airflow‚ hindering starting. Inspect the carburetor for debris or blockages‚ potentially requiring cleaning or adjustment. Ensure the safety bail is fully engaged during the starting process.
Low oil levels can trigger a safety shut-off; check the oil level and add oil if necessary. If the engine turns over but doesn’t fire‚ the issue may lie within the ignition system‚ requiring professional diagnosis.
Uneven Cut
An uneven cut often indicates a dull or damaged mower blade. Sharpen or replace the blade‚ ensuring it’s balanced to prevent vibration. Check the cutting height adjustment; ensure it’s set to the desired and consistent level across all wheels.
Uneven terrain can also contribute to an uneven cut; mow slowly over bumps and dips. Inspect the deck for any obstructions or buildup of grass clippings‚ which can disrupt airflow. Ensure proper overlap with each mowing pass – approximately one-third of the blade width.
Tire pressure significantly impacts cutting consistency; verify all tires are inflated to the recommended pressure.
Excessive Vibration
Excessive vibration can stem from several issues. First‚ inspect the blade for damage‚ imbalance‚ or looseness; a damaged blade must be replaced or properly sharpened and balanced. Check the engine mounting bolts to ensure they are securely tightened‚ as loose bolts contribute to vibration.
Verify all parts are correctly assembled according to the manual‚ as misaligned components can cause imbalance. Inspect the deck for any debris accumulation that might disrupt balance. Ensure the air filter is clean‚ as a restricted air flow can cause engine strain and vibration.
If vibration persists‚ consult a qualified service technician.
