Overview:
Priming the engine is an essential step for getting your lawn mower started. If your lawn mower has a primer bulb, press it 1-2 times before starting the engine. This will help to circulate the fuel and make starting easier.

Steps:
1. In cold weather only push the primer bulb 1-2 times
2.  Stand behind the mower and pull the power lever toward the handle 
grip with one hand.  
3. Place the other hand on the starter handle. Pull the starter handle until you 
feel resistance and then start the engine with a sharp pull. 

4.  Slowly return the recoil handle.

Tips & Warnings:
- Return the recoil handle slowly by hand, DO NOT let it snap back.
- Before starting, ensure the spark plug cap is connected to the spark 
plug and the engine is filled with sufficient oil and gas
