CAUTION
– Periodically check the fuel filter and drain the wa-
ter from it. Otherwise, moisture may flow into the
fuel unit of the engine, resulting in critical faults in
the fuel injection pump, the fuel injection pipe, the
common rail, and injectors. In addition, the per-
formance of the fuel filter may be degraded or
damaged.
– Fuel may be drained when water is drained from
the fuel filter. Fuel is highly inflammable. Fire may
occur when you smoke or use fire near the engine
when draining water from the fuel filter.
– Use clean, specified, and qualified fuel only. Using
irregular or unspecified fuel may result in more
water in the fuel filter.
– Drain the water from the fuel filter if the fuel filter
alarm lamp is turned on. Otherwise, moisture may
flow into the fuel unit, causing the engine to stop.
