How To Start The Engine

CAUTION
This engine was shipped from the factory without oil. If
you start the engine without oil, the engine will be
damaged beyond repair and will not be covered under
warranty.
1. Check the oil level.
2. When starting a new engine for the first time, firmly push
the primer bulb (D) five times. Then for all future starts,
push the primer bulb three times (Figure 1).
NOTE: Priming is usually unnecessary when restarting a
warm engine. However, cool weather may require
priming. If you push the primer bulb too many times, the
engine may flood with fuel and will not start.
3. Engage the brake release lever (E, Figure 3), if product
is equipped.
4. Firmly grasp the starter rope handle (G, Figure 4).
Slowly pull until resistance is felt, then pull quickly to
start the engine.
