Add Fuel
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). High
altitude use, see High Altitude.
• Gasoline with up to 10% ethanol (gasohol) or up to
15% MTBE (methyl tertiary butyl ether) is acceptable.
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).
1. Clean area around fuel fill cap, remove cap.
2. Slowly add regular unleaded fuel (A) to fuel tank (B). Be
careful not to overfill. Allow about 1.5" (4 cm) (C) of
tank space for fuel expansion.
3. Install fuel cap and let any spilled fuel evaporate before
starting engine.
High Altitude
At altitudes over 5,000 feet (1524 meters), 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 2,500 feet (762 meters) with
the high altitude kit is not recommended.
Connect Hose and Water Supply to Pump
NOTE: Remove and discard the shipping caps from the
pump’s high pressure outlet and water inlet before attaching
hoses.
1. Uncoil high pressure hose and attach quick connect
end of hose to base of spray gun. Pull down on collar
of quick connect, slide onto spray gun and let go of
collar. Tug on hose to be sure of tight connection.
