Fuel Tank; Tracking Knob - Husqvarna MZ61 Operator's Manual

Fuel Tank

WARNING! Gasoline is highly flammable.
Observe caution and fill the tank outdoors (see the safety
instruction).
WARNING! The engine and the exhaust system,
become very hot during operation.
Risk for burns if touched.
Allow engine and exhaust system to cool before refueling.
WARNING! Fill to bottom of filler neck. Do not
overfill. Wipe off any spilled oil or fuel. Do not store, spill or
use gasoline near an open flame.
Read the safety instructions before refueling. The capacity for
the tank is 5 gallons (19 liters).
Regularly check the gas cap gasket for damage and keep the
cap properly tightened.
The engine will run on a minimum of 87-octane unleaded
gasoline (no oil mix). Environmentally adapted alkylate
gasoline can be used. See Technical Data concerning ethanol
fuel. Methanol fuel is not allowed. Do not use E85 alcohol
based fuel. Damage to the engine and components may
occur.
When operating in temperatures below 0° C (32° F), use fresh,
clean winter grade gasoline to help insure good cold weather
starting.
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.
