CARBURETOR ADJUSTMENT
WARNING:
If any adjustments are
made to the engine while the engine is
running (e.g. carburetor), disengage all
clutches and blades. Keep clear of all
moving parts. Be careful of heated
surfaces and muffler.
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load. To adjust the carburetor, refer to
the separate engine manual packed with your unit.
NOTE:
A dirty air cleaner will cause an engine to
run rough. Be certain air cleaner is clean and
attached to the carburetor before adjusting
carburetor.

The brake is located by the left rear wheel inside the
frame. During normal operation of this machine, the
brake is subject to wear and will require periodic
examination and adjustment.
WARNING:
Do not have the engine
running when you adjust the brake.
