3. ADJUSTING
CARBURETOR
WARNING:
If any adjustments are made to
the engine while the engine is running (e.g.
carburetor), keep clear of all moving parts.
Be careful of heated surfaces and muffler.
The carburetor has been pre-set at the factory and
should not require adjustment. However, if your
engine does not operate properly due to suspected
carburetor problems, take your chipper-shredder
to
your nearest SEARS service center.
4. ENGINE SPEED
The engine speed on your chipper-shredder
has
been set at the factory.
Do not attempt to increase
engine speed or it may result in personal injury. If you
believe the engine is running too fast or too slow, take
your chipper-shredder
to the nearest SEARS service
center for repair and adjustment.
