(Fig. 7).

Note: If the discharge door does not sit down properly (as
shown in Figure 7), the bag is not properly installed.

Before Starting

Mixing Gasoline and Oil

Your Lawn-Boy lawn mower is powered by a two-cycle
engine which requires a 32:1 mixture of gasoline and oil.

Use only clean, fresh, lead-free gasoline (including
oxygenated or reformulated gasoline) with an octane
rating of 87 or higher. To ensure freshness, purchase only
the amount of gasoline you expect to use in 30 days.
Using unleaded gasoline results in fewer combustion
chamber deposits and longer spark plug life.

IMPORTANT: 

Do not use methanol, gasoline

containing methanol, gasohol containing more than
10% ethanol, premium gasoline, or white gas.  Using
these fuels can damage the engine’s fuel system.

IMPORTANT: 

Do not use automotive oil (i.e., SAE 30

or 10W30), a two-cycle oil that is not NMMA 
TCW III-certified, or a fuel mixed at the wrong
gasoline/oil ratio.  This can cause engine damage not
covered under the Lawn-Boy warranty.
