Fill the Fuel Tank
Turn off the engine, fill with correct diesel fuel according
to the Oil Requirements , and never overfill the tank.
• Do not mix gasoline, alcohol, or their mixture
with diesel fuel.
• Do not refuel the machine while the engine is
running.
• Due to the extremely accurate tolerance match
of the diesel injection system, it is critical to
keep the fuel clean and free of dirt or water.
The dirt or water entering the combustion sys-
tem can cause severe damage to the fuel pump
and injectors.
Replace the Fuel Filter Element
It is recommended to replace the fuel filter element
every 6 months or after 500 hours of operation.
NOTICE
Do not pre-fill the filter, or the filter may be
contaminated.
