CAUTION
Water pump is constantly engaged and operates whenever water pump engine is
running. At least one water inlet valve must be opened whenever water pump
engine is running. A pressure reading on PUMP DISCHARGE gauge (engine
running) indicates adequate water supply to water pump for cooling. Failure to
comply may result in water pump overheating and will cause damage to equipment.
Water pump must be primed when operating water pump engine. Failure to prime
water pump when operating water pump engine will cause damage to equipment.

engine misfires, runs rough, or lacks power.
