Check the Engine
1. Check the fuel level (see page 13). Starting with a full tank will
help to eliminate or reduce operating interruptions for refueling.
2. Check the engine oil level (see page 13). Running the engine
with a low oil level can cause engine damage.
3. Check the air filter element (see page 15). A dirty air filter
element will restrict air flow to the carburetor, reducing engine
and powerhead performance. A damaged air filter element will
allow dust to enter and damage the engine.
4. Check the throttle cable free play (see page 15). Operate the
throttle system several times and check if it the free play (i.e.
throttle lever does not move while operating the throttle
trigger).
