Drain Fuel Filter
--- every 10 hours (daily)
IMPORTANT: Drain fuel filter daily before starting
operation. The engine may be damaged if you do
not drain fuel filter daily. Drained water should
contain fuel. Follow the local regulations when
disposing it.
Fuel pre-filters have water separator function, which
allows float to rise as water accumulates.
Be sure to drain the accumulated water daily until float
goes to the bottom of case.
Draining Procedures (Pre-Filter)
1. Remove two bottom plates (4) of the pre-filter box
by removing the flanged bolt.
2. Connect transparent drain hose (2) stored in the tool
box to drain (1).
3. Place 0.5 liters or larger capacity container under
drain hose (2) to collect the drained water.
4. Rotate drain (1) on the bottom of the filter
counterclockwise. Drain the water accumulated in
the filter until float (5) goes to the bottom of case.
If it is difficult to drain, loosen plug (3) on the top of
the fuel pre-filter.
