Precautions for removal and refitting
1. When replacing the water separator, it is necessary to handle the drained fuel
properly to avoid environmental contamination.
2. When pumping fuel with a hand pump, always unscrew the air drain bolts to avoid
damage to the hand pump.
3. It is prohibited to place the filter near high temperature or open fire to avoid
damage to the water collector and water separator.
4. It is prohibited to wildly operate or knºCk the water separator by using a tool to
avoid damage to the water collector and threads.
5. According to the maintenance requirements, drain filtered water from the water
separator on a regular basis.
6. Upon completion of a new water separator, before first use, always press the hand
pump for 15-30 times to ensure full flow of fuel and normal start of the engine. In
winter or low-temperature area, after first use of the water separator, it is required
to press the hand pump frequently with more than 30 times for each pressing.
CAUTION:
1.Do not tighten the fuel filter and water separator with the water
separator spanner during installation; otherwise the threads may
deform and the filter may be damaged.
