Fuel System Maintenance; Avoiding Fuel-Related Problems - Honda HRN216VKU Owner's Manual

When maintained properly, your Honda lawn mower should provide years of trouble-free operation. This includes the fuel system. However,
petrol can quickly deteriorate, causing starting or running problems and, in some cases, damage to the fuel system. Most fuel-related problems
can be avoided by following the precautions listed below. Fuel system damage and engine performance problems resulting from deteriorated
fuel are not covered by the LIMITED WARRANTY (see
Follow These Precautions to Prevent Most Fuel-Related Problems
During the Normal Mowing Season
Do not use petrol containing more than 10% ethanol.
Store petrol in a clean, plastic, sealed container approved for fuel
storage.
Store your fuel supply container away from direct sunlight; if the
container has a vent, keep it closed.
Purchase only enough petrol to last for 30 to 60 days.
If you purchase enough petrol to last for more than 60 days, add a
fuel stabilizer to your storage tank when you fill it.
When you finish mowing, turn the fuel valve OFF and fill the
mower's fuel tank.
3 to 4 Weeks Before Next Use
Turn the fuel valve OFF and fill the mower's fuel tank.
With the fuel valve off, start the engine and let it run until it runs out
of petrol. Running time should be approximately 3 minutes.
1 to 3 Months Before Next Use
If you did not add fuel stabilizer to your fuel storage tank when you
filled it up, fill your mower's fuel tank with fresh petrol.
Add fuel stabilizer to the mower tank according to the stabilizer
manufacturer's instructions.
Run the engine outdoors for 10 minutes.
Stop the engine and turn the fuel valve OFF. Restart the engine and
let it run until it runs out of petrol. Running time should be
approximately 3 minutes.
More Than 3 Months Before Next Use
Start the engine and let it run long enough to empty all the petrol
from the entire fuel system, including the fuel tank. Do not allow
petrol to remain in your lawn mower for more than 3 months of
inactivity.
We recommend Pro Honda Fuel Stabilizer that has an improved formulation with added corrosion protection.

AVOIDING FUEL-RELATED PROBLEMS

A high level of ethanol in petrol attracts water and can corrode or
damage the fuel system and cause performance problems.
A clean plastic container will prevent rust and metallic contaminants
from entering the fuel system.
Petrol will deteriorate faster when exposed to air and sunlight.
Petrol deteriorates with age, so try to avoid storing it for long
periods, especially in summer heat.
Fuel stabilizer will extend the shelf life of petrol, but it will not
reconstitute stale fuel.
If the fuel tank is only partially filled, air in the tank will promote fuel
deterioration.
If the fuel tank is only partially filled, air in the tank will promote fuel
deterioration.
The small amount of petrol in your lawn mower's carburetor will
deteriorate faster than the fuel in the fuel tank due to its small
volume and heat from the engine.
If the fuel tank is only partially filled, air in the tank will promote fuel
deterioration.
Fuel stabilizer will extend the life of petrol, but it will not reconstitute
stale petrol.
To make sure treated petrol has replaced untreated petrol
throughout the fuel system.
The small amount of petrol in your lawn mower's carburetor will
deteriorate faster than the fuel in the fuel tank due to its small
volume and heat from the engine.
All fuel stabilizers have a shelf life. It is good practice to empty the
fuel system for long-term inactivity.
