Procedures
Preparing for Maintenance
1. Move the machine to a level surface.
2. Stop the engine and wait for all moving parts to stop.
3. Disconnect the wire from the spark plug, and secure
the wire so it cannot come in contact with the spark
plug (Figure 19).

WARNING
Tipping the machine may cause the fuel to leak
from the carburetor or the fuel tank. Gasoline
is extremely flammable, highly explosive, and,
under certain conditions, can cause personal
injury or property damage.
Avoid fuel spills by draining the gasoline to an
acceptable level with the fuel valve; never siphon.
4. If you must tip the machine and there is fuel
in the fuel tank, empty the fuel tank; refer to
Emptying the Fuel Tank (page 21).
Note: If possible, wait to perform maintenance
until the fuel tank is nearly empty from running the
machine during normal operation.
