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.
BRAKE ADJUSTMENT (See figure 20)
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.
Figure 20
To adjust the brake, adjust the lock nut so the brake

5/16" away from the axle housing.
NOTE: Figure 20 is shown with the unit tipped up
on rear wheels for clarity only.
