CARBURETOR ADJUSTMENTS
A WARNING: If any adjustments are made to
the engine while the engine is running
(e.g. carburetor), disengage all clutches

Be careful of heated surfaces and muffler.
Minor carburetor adjustments may be required to
compensate for differences in fuel, temperature,
altitude and load. Refer to separate engine manual
for carburetor adjustment information.
NOTE: A dirty air cleaner will cause an engine to runrough.
Be certain air cleaner is clean and attached to
the carburetor before adjusting carburetor.

by following instructions in Assembly section.
BRAKE ADJUSTMENT (See figure 15)
The brake is located by the right rear wheel inside the
frame. During normal operation of this machine, the
brakes are subject to wear and will require periodic ex-
amination and adjustment.
A WARNING: Do not adjust the brake while
the engine is running. Be sure to block the
wheels of the tractor before making the
brake adjustment.
