2. Assembly – From Box to Yard

Before you can start the mower, a few simple assembly tasks are required. Grab a screwdriver (usually supplied) and follow these steps:

  1. Attach the handle. Align the handle’s mounting holes with the engine’s brackets and tighten the bolts until the handle is firm but not over‑tightened.
  2. Install the blade guard. Slide the guard onto the blade shaft, ensuring the slots line up with the guard’s clips.
  3. Fit the leaf‑catcher (optional). Clip the bag onto the rear of the mower if you prefer a cleaner finish.

All connections should be snug; a loose handle can cause vibration, while an ill‑fitted guard may affect cutting performance.

3. Preparing the Engine

Proper preparation is essential for a smooth start. The Mac Allister B&S 300E uses a four‑stroke petrol engine that requires oil and a clean spark plug.
