How to Avoid Fuel Contamination
From Dirt and Dust
Dirt and dust cause more than 85% of all failures in fuel systems and can reduce engine life by 50%. Even tiny amounts of dirt and dust in your machine’s fuel system can obstruct to the engine’s normal processes. Newer engines are even more susceptible to damage, because the fuel injection pressure is higher, and the smallest particles can impair normal engine functions.
Fueling
When you refuel, always replace the nozzle back onto the pump, rather than letting it fall on
the ground where it could gather dust.
Operation
Prevent dust from entering the fuel system by making sure the vent tube and fuel tank caps are
tightly sealed.
Servicing
Minimize the possibility of exposing the engine to the air to reduce the risk of introducing
dirt and dust into the fuel system. Whenever you change filters, refuel or make any type of
engine repairs, complete these tasks indoors, if possible, where there is less chance of
contamination.
Filters
Change filters promptly at the manufacturer’s suggested intervals. Clogged filters cannot
prevent dirt from circulating through your engine. Use filters that are approved by the
equipment manufacturer to assure best results. Carefully follow the instructions provided in
your equipment operator’s manual when changing both the main filters and the prefuel filters, so
that dust does not enter the fuel system during this process. Always check seals to detect
possible leaks. Never pre-fill fuel filters in high pressure fuel systems.
From Water
Prevent condensation
At night, condensation can occur when the temperature drops while the equipment is not
operating, and water may enter the fuel tank. To avoid the formation of condensation, fill up
the tank at the end of each day.
Drain water & sediment
Before beginning to operate your equipment each day, drain the water and sediment that has
accumulated at the bottom of the tank. Similarly, about ten minutes after refueling, water and
sediment should be drained from the fuel tank.
How to Reduce Fuel Usage
Inspect air filters regularly
Inspect your air filters every 50 hours. If the pleats of your filter are clogged with dirt, it
is time to change the filter. Cleaning the air filter can damage it and is not recommended. When
an air filter becomes clogged with dirt, the engine cannot get the air it needs and does not
operate efficiently.
Grease fittings properly
Lubricate your machine according to the manufacturer’s recommendations. By keeping your machine
properly lubricated, fuel efficiency is increased simply because the power needed to perform
operations is reduced.
Check tire pressure
Check tire air pressure before and after each use. If the tire pressure is low, fill the tires
as soon as possible. Low air pressure can reduce the efficiency of your machine and lower fuel
efficiency.
Be alert for signs of a mechanical problem
When you see signs of a mechanical problem, bring your machine in to repair before the problem
gets worse. Mechanical problems, such as a fuel injector that is overfueling a cylinder, can
significantly reduce fuel efficiency.
Run your engine at low RPM when possible
When a job does not require maximum power, running the engine at a lower rpm can significantly
reduce fuel consumption. Begin by running at a low rpm during operation, then slowly raise the
rpm until the engine does not strain to find the optimum rpm for the job.
Service your equipment regularly
Follow the manufacturer’s guidelines for servicing your equipment. Most require service at least
every 500 hours. The best way to ensure that your machine is working efficiently is to service
it regularly.
