Safety Information

Operating any power equipment can be hazardous. Always follow these safety guidelines to prevent injury or property damage:

• Read the Entire Manual: Familiarize yourself with all controls and proper use of the equipment.
• Wear Appropriate Safety Gear: Always wear eye protection, hearing protection, long pants, and sturdy footwear.
• Keep Bystanders Away: Ensure children, pets, and other people are at a safe distance (at least 50 feet) from the operating area.
• Inspect Work Area: Clear the area of debris, rocks, wires, or other objects that could be thrown by the trimmer line.
• Handle Fuel Safely: Gasoline is highly flammable. Refuel outdoors in a well-ventilated area with the engine off and cool. Do not smoke while refueling.
• Maintain Control: Operate the trimmer mower with a firm grip on the handles. Do not overreach.
• Engine Heat: The engine and muffler become very hot during operation and can cause burns. Allow the engine to cool before touching or storing.
• Never Operate Indoors: Engine exhaust contains carbon monoxide, a colorless, odorless, and deadly gas.

Setup

1. Assembly

The YL2250 requires some assembly. Typically, this involves attaching the handle assembly and ensuring all fasteners are secure. Refer to the detailed assembly diagrams in the separate assembly guide for specific steps.

2. Fuel and Oil

• Engine Oil: Before starting, ensure the engine crankcase is filled with the recommended engine oil to the proper level. Consult the engine manual for oil type and capacity.
• Fuel: Fill the fuel tank with fresh, unleaded gasoline (minimum 87 octane). Do not use E85 or E15 fuel. Do not overfill.

3. Trimmer String Loading

The YL2250 features an onboard cord caddy for convenient storage of extra, pre-cut trimmer strings. To load new string:

1. Ensure the engine is off and cool.
2. Locate the trimmer head.
3. Insert the pre-cut trimmer lines into the designated slots on the trimmer head. Ensure they are securely seated.

4. Cutting Height Adjustment

The cutting height can be adjusted without tools to one of 5 positions, ranging from 1.5 inches to 3.5 inches. Locate the height adjustment mechanism, typically near the wheels or cutting deck, and select the desired height.

Operating Instructions

1. Ensure the fuel valve is open (if applicable).
2. Set the choke to the START or CHOKE position.

4. Pull the starter rope firmly until the engine starts.

• Air Filter: Inspect and clean or replace the air filter regularly, especially when operating in dusty conditions.
