Water draining from fuel filter
An oil filter has two functions: oil filtering and water separa-
tion.
1. the water separation function of the fuel filter discharges
water and sediment from the water separator.
2. Stop the engine, and loosen the drain plug for water
separation manually.

the cartridge until fuel is discharged.
4. Tighten the drain plug for water separation by turning it
clockwise.

Fuel may be drained when water is drained from the fuel
filter. Fuel is highly inflammable. Fire may occur when
you use fire near the engine when draining water from
the fuel filter.
• Do not tighten the plug excessively because it may
damage the screw.
• If you do not check the fuel filter regularly and drain
the water in the fuel filter, water flows into the fuel
system of the engine, causing serious failure in the
fuel system, etc., and decrease in or damage to the
fuel filter performance. Inflow of water to the fuel
system may stop the engine.
• Use clean, specified, and qualified fuel only. using
irregular or unspecified fuel may result in more
water in the fuel filter.
Do not reuse the cartridge; replace them with new ones.
