Operation – Preparing the Water Pump for Each Use

2. Environment
conditions
Ambient Operating Temperature Range. +5 °F to +104 °F (-15 °C to +40 °C). If
operating pump below +32 °F (0 °C) drain pump after use to prevent damage from
freezing.
Humidity. 95% max. If possible, avoid any area with high humidity. Humidity
promotes rust and corrosion.
Altitude. If operation of the engine is always at altitudes HIGHER than 6,000 feet
(1828.8 m) above sea level, have an authorized Honda Engine dealer perform
carburetor modifications. At high altitude, the standard carburetor air/fuel mixture
will be excessively rich. Performance will decrease while fuel consumption will
increase.
NOTICE: Operation of the engine at an altitude LOWER than the carburetor is
modified for may result in reduced performance, overheating, and serious engine
damage caused by an excessively lean air/fuel mixture.
3. Use flexible hose
Use at least 12” (30.5 cm) of flexible hose to make plumbing connections to the
pump body. Rigid piping may put stresses on the pump, causing damage.
4. Place unit on
secure footing
Always be sure the unit is on a secure footing. Keep the immediate pump area free
of all unauthorized personnel. If the water pump is sitting beside a pit, be sure it is
well anchored so that it does not fall in.
5. Do not run the
pump dry
Do not run the pump dry. Always fill the pump body with water before starting. It
is not necessary to drain the pump body after each use, unless there is danger of
freezing, settling of solids, or crystallization.
6. Fill the pump
with water
Fill the pump with water utilizing the priming port on the top of the pump.
(The pump self primes only when it is first filled with priming water.)
All hoses and pipe connections must be airtight.
