discharges water and sediment from the water
separator.
2. Stop the engine, and loosen the drain plug for water
separation manually.

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 seri
ous
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.
