WARNING
POTENTIAL HAZARD
Gasoline is extremely flammable, highly
explosive and under certain conditions can
cause personal injury or property damage.
WHAT CAN HAPPEN
Tipping the lawn mower may cause fuel leakage
from the carburetor or fuel tank.
HOW TO AVOID THE HAZARD
Avoid fuel spills by running the engine dry or
removing gas with a hand pump; never siphon.
5. Tip the lawn mower onto its left side (Fig. 17).

IMPORTANT: Move the blade as little as possible to
avoid future starting problems.
Inspecting the Blade
Carefully examine the blade for sharpness and wear,
especially where the flat and the curved parts meet
(Fig. 18A). Because sand and abrasive material can wear
away the metal that connects the flat and curved parts of
the blade, check the blade before using the lawn mower. If
you notice a slot or wear (Figs. 18B and 18C), replace the
blade; refer to Removing the Blade on page 16.

Note: For the best performance, install a new blade before
the cutting season begins. During the year, file down any
small nicks to maintain the cutting edge.
POTENTIAL HAZARD

piece of the blade could be thrown into the
operator's or bystander's area.

WHAT CAN HAPPEN

personal injury or death to the operator or

Inspect the blade periodically for wear or
damage.
Replace a worn or damaged blade.

Grasp the end of the blade using a rag or thickly padded
glove. Remove the blade bolt, the lock washer, the
