2. Setup and Assembly
Before operating your new Murray EQ2-400 lawn mower, some initial setup and assembly are required. Please follow these steps carefully:
- Unboxing: Carefully remove all components from the packaging. Ensure all parts listed in the packing list are present.
- Handle Assembly: Unfold the ergonomic handle and secure it in place using the provided fasteners. Ensure the handle is firmly locked to prevent movement during operation.

3. Operation Guide
3.1. Starting the Engine
Ensure the fuel tank is filled and the oil level is correct. For cold starts, prime the engine as per the instructions on the engine itself. Pull the starter cord firmly until the engine starts. Allow the engine to warm up for a few moments before engaging the blade.

3.2. Adjusting Cutting Height
The Murray EQ2-400 features a convenient 6-level central cutting height adjustment system, ranging from 25 mm to 75 mm. To adjust the cutting height, locate the central lever near the wheels. Move the lever to your desired height setting. Always adjust the cutting height when the engine is off and the blade is stationary.

3.3. Mowing Functions (2-in-1)
Your mower offers two primary mowing functions:
- Collecting: For a tidy lawn, attach the 50-liter grass collection bag. The bag features dust protection and a fill indicator to let you know when it needs emptying.
- Rear Discharge: For situations where collecting grass is not necessary, you can operate the mower without the grass bag, allowing the clippings to be discharged from the rear.

4. Maintenance and Care
Regular maintenance ensures the longevity and optimal performance of your Murray lawn mower. Always ensure the engine is off and the spark plug wire is disconnected before performing any maintenance.
4.1. Cleaning the Mower
The mower is equipped with an integrated wash port for easy cleaning of the cutting deck. After each use, connect a garden hose to the wash port, turn on the water, and start the engine for a short period (as per the engine manual). This will help dislodge grass clippings from the underside of the deck.

4.2. General Maintenance Tips
- Check Oil Level: Regularly check the engine oil level before each use and top up if necessary.
- Clean Air Filter: Inspect and clean the air filter periodically to ensure proper engine performance.
- Inspect Blade: Check the cutting blade for sharpness and damage. A dull or damaged blade can lead to an uneven cut and strain the engine.
- Spark Plug: Inspect and clean or replace the spark plug as recommended in the engine manual.
- Storage: When storing the mower for extended periods, especially during off-season, ensure the fuel tank is empty or treated with a fuel stabilizer. Clean the mower thoroughly and store it in a dry, protected area. The ergonomic handle can be folded to reduce storage space.
