2. Safety Information

Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury. Failure to follow these instructions may result in serious injury or death.

• Read and understand all instructions before operating the machine.
• Keep children and pets away from the mowing area.
• Wear appropriate personal protective equipment (PPE), including eye protection, hearing protection, and sturdy footwear.
• Never operate the mower in wet grass or rain.
• Turn off the engine and disconnect the spark plug wire before performing any maintenance or clearing blockages.
• Refuel in a well-ventilated area with the engine off and cool.

3. Setup and Assembly

Your lawn mower may require some assembly before first use. Follow these steps carefully.

3.1 Handle Assembly

1. Unfold the lower handle section and secure it to the mower deck using the provided bolts and knobs.
2. Attach the upper handle section to the lower section, ensuring all cables are routed correctly and not pinched.
3. Tighten all fasteners securely.

3.2 Fuel and Oil Filling

This mower uses a 4-stroke gasoline engine. Do NOT mix oil with gasoline.

• Engine Oil: Remove the oil dipstick/fill cap. Fill the engine with recommended 4-stroke engine oil (e.g., SAE 30 or 10W-30) to the 'FULL' mark on the dipstick. Do not overfill.
• Gasoline: Fill the fuel tank with fresh, unleaded gasoline (minimum 87 octane). Do not overfill. Leave space for fuel expansion.

3.3 Adjusting Cutting Height

The TOYAMA TLM510SM-50L features height regulation for precise cutting.

1. Ensure the engine is off and the spark plug wire is disconnected.
2. Locate the height adjustment levers, typically near the wheels.
3. Pull the lever outwards and move it to the desired cutting height position. Ensure all wheels are set to the same height for an even cut.

4. Operating Instructions

4.1 Starting the Engine

1. Ensure the fuel tank is filled and the oil level is correct.
2. Move the throttle lever to the 'START' or 'CHOKE' position (if equipped).
3. Press the primer bulb 3-5 times (if equipped) until fuel is visible in the bulb.
4. Grip the engine brake lever against the handle.
5. Pull the starter rope with a quick, firm motion until the engine starts.
6. Once started, gradually move the throttle to the 'RUN' position.

4.2 Mowing Techniques

The TLM510SM-50L is a 2-in-1 function mower, offering mulching and side discharge capabilities.

• Mulching: For mulching, ensure the side discharge chute is closed and any grass bag is removed. The mower will finely cut grass clippings and return them to the lawn as natural fertilizer.
• Side Discharge: For side discharge, attach the side discharge chute. This will direct clippings out from the side of the mower.
• Overlap cutting swaths slightly to ensure an even cut.
• Avoid cutting more than one-third of the grass blade length at a time.
• Mow across slopes, not up and down, to maintain control.

5. Maintenance

Regular maintenance ensures optimal performance and extends the life of your lawn mower.

5.1 Engine Oil

• Check Oil Level: Before each use, check the oil level using the dipstick. Add oil if necessary.
• Change Oil: Change the engine oil after the first 5 hours of operation, then every 25 hours or annually, whichever comes first.

5.2 Air Filter

• Clean/Replace: Inspect the air filter every 25 hours or more frequently in dusty conditions. Clean or replace as needed. A dirty air filter can reduce engine performance.

5.3 Spark Plug

• Inspect/Replace: Inspect the spark plug annually or every 50 hours. Clean or replace if fouled or damaged. Ensure correct gap.

5.4 Cutting Blade

• Inspect: Regularly inspect the cutting blade for sharpness and damage. A dull blade tears grass, leading to an unhealthy lawn.
• Sharpen/Replace: Sharpen or replace the blade as necessary. Always ensure the engine is off and the spark plug wire is disconnected before handling the blade.

5.5 Cleaning and Storage

• Clean Deck: After each use, clean grass clippings from the underside of the mower deck to prevent buildup and corrosion.
• Long-Term Storage: For storage longer than 30 days, drain the fuel tank or use a fuel stabilizer. Store in a dry, protected area.

8. User Tips

• For best mulching results, mow frequently and when the grass is dry.
• Always clean the underside of the deck after each use to prevent grass buildup, which can affect cutting performance and lead to rust.

• Consider using a fuel stabilizer if you don't use up a full tank of gasoline within a few weeks.
