STORAGE
With the engine and exhaust system cool, cover the mower to
keep out dust. A hot engine and exhaust system can ignite or
melt some materials. Do not
use
sheet plastic as a dust cover. A
nonporous cover will trap moisture around the mower, promoting
rust and corrosion.
Removal From Stoiage
Check your mower as described in the BEFORE MOWING
chapter of this manual.
If the fuel was drained during storage preparation, fill the tank
with fresh gasoline. If you keep a container of gasoline for
refueling, be sure that it contains only fresh gasoline. Gasoline
oxidizes and deteriorates over time, causing hard starting.
If the cylinder was coated with oil during storage preparation, the
engine will smoke briefly at startup. This is normal.
