3. Slowly add regular unleaded fuel (A) to fuel tank (B).
Be careful not to overfill. To allow for fuel expansion,
do not fill above the bottom of the fuel tank neck.
4. Install fuel cap and let any spilled fuel evaporate
before starting engine.
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.
Assemble and Attach Hoses
You will need the following tool to install the hoses to the
water pump:
• 10 mm nut driver
Connect Suction Hose to Pump
Use a commercially available hose. The suction hose
must be reinforced with a non-collapsible wall or
braided material. DO NOT use a hose with an inside
diameter smaller than the pumps suction port size.
1. Slide barb cuff over hose barb. Insert rubber seal
into end of barb cuff. Figure
2. Screw hose barb assembly onto pump in clockwise
rotation until hose barb assembly is tightened
securely. Figure

3. Slide hose clamp over end of hose. Slide suction
hose onto hose barb. Tighten hose clamp securely
using a standard 10 mm nut driver. Figure
Attach Suction Hose to Strainer Basket Figure
Slide hose clamp over hose. Attach open end of
suction hose to strainer hose barb. Tighten hose clamp
securely using a standard 10 mm nut driver.
Connect Discharge Hose (Optional)
If desired, use a commercially available hose. DO NOT
use a hose with an inside diameter smaller than the
pump's discharge port size.
1. Slide barb cuff over hose barb. Insert rubber seal
into end of barb cuff.
2. Screw hose barb assembly onto pump in clockwise
rotation until hose barb assembly is tightened
securely. Figure

3. Slide hose clamp over end of discharge hose.
Slide discharge hose onto hose barb. Tighten
hose clamp securely using a standard 10 mm nut
driver. Figure

Operation
Water Pump Location
For best pump performance, locate the pump on a
flat, level surface as close as possible to the water to
be pumped. Secure water pump to avoid tipover. Use
hoses that are no longer than necessary.
• Keep at least 1.5 m (5 ft) of clearance on all sides

What is "Head"? Figure
Head refers to the height of a column of water that can
be delivered by the discharge of the pump.
Suction Head (A) is the vertical distance between the
center of the pump and the surface of the liquid on the
suction side of the pump. May also be referred to as
"suction lift". The atmospheric pressure of 1 bar (14.5
psi) at sea level limits suction head lift to less than
approximately 8m (26 ft) for any pump.
Discharge Head (B) is the vertical distance between
the pump's discharge port and the point of discharge,
which is the liquid surface if the hose is submerged or
pumping into the bottom of a tank.
WARNING Exhaust heat/gases could ignite
combustibles, structures or damage fuel tank
causing a fire, resulting in death or serious
injury.
of water pump including overhead.
WARNING POISONOUS GAS HAZARD. Engine
exhaust contains carbon monoxide, a
poisonous gas that could kill you in minutes.
You CANNOT see it, smell it, or taste it. Even
if you do not smell exhaust fumes, you could still be
exposed to carbon monoxide gas. If you start to feel
sick, dizzy or weak while using this product, get to
fresh air RIGHT AWAY. See a doctor. You may have
carbon monoxide poisoning.
• Operate this product ONLY outside far away from
windows, doors and vents to reduce the risk of
carbon monoxide gas from accumulating and
potentially being drawn towards occupied spaces.
• Install battery-operated carbon monoxide alarms or
plug-in carbon monoxide alarms with battery back-
up according to the manufacturer's instructions.
Smoke alarms cannot detect carbon monoxide gas.
• DO NOT run this product inside homes, garages,
basements, crawlspaces, sheds, or other partially-
enclosed spaces even if using fans or opening doors
and windows for ventilation. Carbon monoxide can
quickly build up in these spaces and can linger for
hours, even after the product has shut off.
• ALWAYS place this product downwind and point
the engine exhaust away from occupied spaces.
