2. Safety Information

Always prioritize safety when operating power equipment. Read and understand all safety warnings and instructions before use. Failure to do so may result in serious injury.

• Wear appropriate personal protective equipment (PPE), including eye protection, hearing protection, long pants, and sturdy footwear.
• Keep bystanders, children, and pets at a safe distance (at least 50 feet) from the operating area.
• Inspect the work area for debris that could be thrown by the cutting line. Remove rocks, sticks, and other objects.
• Do not operate the mower in wet conditions or on excessively steep slopes.
• Ensure the engine is off and the cutting head has stopped before performing any maintenance, adjustments, or clearing debris.
• Handle fuel with extreme care. Store in an approved container, in a well-ventilated area, away from ignition sources.
• Never leave the mower unattended while the engine is running.

3. Setup

The Earthquake M605 is designed for minimal assembly. Follow these steps to prepare your mower for first use:

1. Unfold Handlebars: Carefully unfold the handlebars to their upright operating position.
2. Tighten Knobs: Securely tighten the tool-less handlebar knobs to ensure the handlebars are firm and stable.
3. Add Engine Oil: Locate the oil fill cap on the engine. Using the provided 4-cycle engine oil, carefully fill the engine to the recommended level. Refer to the engine manufacturer's manual for exact oil capacity and type.
4. Add Fuel: Fill the fuel tank with fresh, clean unleaded gasoline. Do not overfill. Ensure the fuel cap is securely tightened.
5. Install Starter Strings: If not pre-installed, attach the starter strings to the mower head as per the instructions provided with the strings.
6. Check Belt Tensioner: (As per customer review, may need adjustment) Verify the belt tensioner is properly set. Adjust if necessary to ensure optimal performance.
7. Adjust String Head Height: Adjust the height of the string head to suit your cutting needs.

4. Operating Instructions

Operating your Earthquake M605 String Mower effectively and safely.

Starting the Engine:

1. Ensure the mower is on a level surface.
2. Verify the fuel tank is adequately filled and the oil level is correct.
3. Engage the engine brake lever (if applicable) or ensure the bail system is in the disengaged position.
4. Pull the starter cord firmly and smoothly until the engine starts. Multiple pulls may be required.

Cutting Operation:

• Once the engine is running, engage the integrated clutch and hand bail system to start the trimmer head.
• Guide the mower through thick grass, weeds, and brush. The large 14-inch wheels are designed to float over uneven terrain.
• For very tall or dense growth, make multiple passes, gradually reducing the height. Avoid forcing the mower through excessively thick material.
• If the trimmer head binds or encounters heavy debris, release the hand bail to disengage the cutting head. Clear the obstruction before re-engaging.
• Maintain a steady pace and keep both hands on the handlebars for control.

5. Maintenance

Regular maintenance ensures optimal performance and extends the life of your string mower. Always ensure the engine is off and cool before performing any maintenance.

• String Replacement: The super tough nylon line will wear down during use. Replace the string as needed. Refer to the product's specific instructions for your model for proper string type and replacement procedure.
• Cleaning: After each use, clean grass clippings and debris from the deck, cutting head, and engine cooling fins. A clean machine runs more efficiently.
• Oil Level Check: Check the engine oil level before each use. Top up if necessary with the recommended 4-cycle engine oil.
• Air Filter: Inspect and clean the air filter regularly. A dirty air filter can reduce engine performance.
• Spark Plug: Inspect the spark plug periodically. Clean or replace if fouled or worn.
• Storage: When storing for extended periods, especially over winter, ensure the fuel system is properly prepared to prevent issues from stale fuel. This may involve running the engine dry or using a fuel stabilizer. Fold down the handlebars for easier storage.
