CoNTRolS
IMPORTANT INFORMATION Experience indicates that
alcohol blended fuels (called gasohol, ethanol or methanol)
can attract moisture which leads to separation and
formation of acids during storage. Acidic gas can damage
the fuel system of an engine while in storage. To avoid
engine problems, the fuel system should be emptied before
storage of 30 days or longer. Drain the gas tank, start the
engine and let it run until the fuel lines and carburetor are
empty. Use fresh fuel the next season. See Storage for
additional information. Never use engine or carburetor
cleaners in the fuel tank or permanent damage may occur.
Tracking Knob
If the mower is not tracking straight, check the air pressure in
both rear tires. Recommended air pressure is 15 psi (103 kPa /
1 bar) for all tires. Tracking must be checked on a flat and level
concrete or blacktop surface.
Rotating the tracking knob allows fine tuning adjustments so
the machine tracks straight with the steering control levers in
the full forward position.
Rotate the knob counter clockwise (as viewed from the
operation position) to increase the speed on the left lever.
Rotate clockwise to decrease speed.
