Assembly
Read entire operator’s manual before you attempt
to assemble or operate your new water pump.
Every effort has been made to ensure that information
in this manual is accurate and current. However, we
reserve the right to change, alter or otherwise improve
the product and this document at any time without prior
notice.
Your water pump requires some assembly and is ready
for use after it has been properly serviced with the
recommended oil and fuel.
If you have any problems with the assembly of your
water pump, please contact the store at which you
purchased the unit or any authorized dealer. If calling
for assistance, please have the model, revision, and
serial number from the ID label available.
Unpack Water Pump
1. Remove everything from carton except water pump.
2. Open carton completely by cutting each corner from top
to bottom.
3. Ensure you have all included items prior to assembly.
Items in the carton include:
• Water pump
• Parts bag (which includes the following):
• Operator’s manual
• Coupler assembly kit
• Vibration mount kit
To prepare your water pump for operation, you will
need to perform these tasks:
1. Add oil to engine crankcase.
2. Add fuel to fuel tank.
3. Move water pump to safe operating location.
4. Assemble and connect hoses.
5. Locate strainer basket into water source.
6. Prime the water pump.
Add Engine Oil
Figure
1
1. Place water pump on a flat, level surface.
2. Clean area around oil fill (
A
) and remove oil dipstick.
3. Using oil funnel (optional), slowly pour recommended
oil into oil fill opening until the point of overflowing (
B
).
Verify oil is the correct viscosity for current
ambient temperature.
NOTICE
Improper treatment of water pump could damage
it and shorten its life.
• DO NOT attempt to crank or start the engine before it
has been properly serviced with the recommended oil.
This could result in an engine failure.
4. Replace oil fill cap and fully tighten.
Add Fuel
Figure
2
Fuel must meet these requirements:
• Clean, fresh, unleaded petrol.
• A minimum of 87 octane/87 AKI (91 RON). For high
altitude use, see
High Altitude.
• Petrol with up to 10% ethanol (gasohol) is acceptable.
NOTICE
Use of unapproved fuels will damage the
engine components and void the engine warranty.
• DO NOT use unapproved petrol, such as E15 and
E85.
• DO NOT mix oil in petrol or modify the engine to
run on alternate fuels.
To protect the fuel system from gum formation, mix in a
fuel stabilizer when adding fuel. See Storage. All fuel is
not the same. If you experience starting or performance
problems after using fuel, switch to a different fuel
provider or change brands. This engine is certified to
operate on gasoline. The emission control system for this
engine is EM (Engine Modifications).
WARNING
Fuel and its vapors are extremely flammable
and explosive which could cause burns, fire or
explosion resulting in death or serious injury .
WHEN ADDING FUEL
• Turn water pump OFF and let it cool at least 2 minutes
before removing fuel cap. Loosen cap slowly to relieve
pressure in tank.
• Fill or drain fuel tank outdoors.
• DO NOT overfill tank. Allow space for fuel expansion.
• If fuel spills, wait until it evaporates before starting engine.
• Keep fuel away from sparks, open flames, pilot lights,
heat, and other ignition sources.
• Check fuel lines, tank, cap and fittings frequently for
cracks or leaks. Replace if necessary.
• DO NOT light a cigarette or smoke.
1. Make sure water pump is on a level surface.
2. Clean area around fuel fill cap and remove cap.
3. Slowly add unleaded gasoline (
A
) to fuel tank (
B
).
Be careful not to fill above the baffle (
C
). This allows
adequate space for fuel expansion as shown.
4. Install fuel cap and let any spilled fuel evaporate before
starting engine.
Fresh fuel prevents gum from forming in the fuel
system or on essential carburetor parts. Purchase fuel
in quantity that can be used in 30 days.
High Altitude
At altitudes over 1524 meters (5,000 feet), a minimum
85 octane / 85 AKI (89 RON) gasoline is acceptable. To
remain emissions compliant, high altitude adjustment is
required. Operation without this adjustment will cause
decreased performance, increased fuel consumption,
and increased emissions. See an Authorized Briggs &
Stratton dealer for high altitude adjustment information.
Operation of the engine at altitudes below 762
meters (2,500 feet) with the high altitude kit is not
recommended.
