STORAGE

Proper storage is essential for keeping your
lawnmower troublefree and looking good. The
following steps will help protect the mower from rust
and corrosion, and make the engine easier to start when you use the
lawnmower again.

CLEANING

Engine
Clean the engine by hand, using a rag and a brush.
NOTICE
Using a garden hose or pressure washing equipment can force water into the
air cleaner. Water in the air cleaner will soak the paper filter and can enter the
carburetor or engine cylinder, causing damage. Water contacting a hot
engine can cause damage. If the engine has been running, allow it to cool for
at least half an hour before cleaning.
Cutting-means Enclosure
To assure a longer lifetime and more efficient operation, the underside of
the lawnmower must be kept clean and free of grass debris by cleaning
with a brush and scraper. After use the lawnmower must be cleaned
thoroughly before being stored.
Before cleaning the underside of the cutting-means enclosure, allow the
engine to cool and be sure the fuel valve is in the OFF position. Disconnect
the spark plug cap. Rest the mower on its right side so the fuel filler cap is
up. This will help prevent fuel leakage and hard starting due to carburetor
flooding. Wear heavy gloves to protect your hands from the cutting
means.
Grass catcher
Remove the catcher from the mower, and wash it with a garden hose or
pressure washing equipment. Allow the catcher to dry completely before
storage.
After the lawnmower is clean and dry, touch up any damaged paint and
coat other areas that may rust with a light film of oil.
Correction
Apply less pressure to the Smart Drive
control or push slower.
Set both levers at the same cutting height
position (page 7).
Empty the grass catcher. Wash the grass
catcher if it is clogged with dirt (page 14).
Clean out the cutting-means enclosure
(page 10).
Sharpen or replace the cutting means if
necessary (page 13).
