Checking and Adjusting Transmission Tracking
CAUTION: Avoid injury! Engine exhaust fumes contain carbon monoxide and can cause seri- ous illness or death.
•Move the machine to an outside area before running the engine.
•Do not run an engine in an enclosed area with- out adequate ventilation.
•Connect a pipe extension to the engine exhaust pipe to direct the exhaust fumes out of the area.
•Allow fresh outside air into the work area to clear the exhaust fumes out.
NOTE: Check and adjust transmission tracking on a hard, level surface.
