CAUTION!
Alcohol-blended fuels (called gasohol, ethanol or
methanol) can attract moisture, which leads to separation and
formation of acids during storage. Acidic gas can damage the
fuel system of an engine while in storage.
To avoid engine problems, the fuel system should be treated
with a fuel preserver or emptied before storage of 30 days or
longer. If adding a fuel preserver, fill the fuel tank with fresh
fuel. If only partially filled, air in the tank will promote fuel
deterioration during storage. If fuel preserver is not used,
drain the fuel tank, start the engine and let it run until the fuel
lines and carburetor are empty. Use fresh fuel next season.
See Storage for additional information.
NEVER use engine or carburetor cleaner products in the fuel
tank as permanent damage may occur.
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 a qualified Sears 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
DO NOT run the pump without the water supply connected
and turned on.
• Damage to equipment resulting from failure to follow this
instruction will void warranty.
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 one end of hose to
base of spray gun. Tighten by hand.
The high pressure stream of water that this
equipment produces can cut through skin and its
underlying tissues, leading to serious injury and
possible amputation.
• NEVER connect high pressure hose to nozzle extension.
• Keep high pressure hose connected to pump and spray gun
while system is pressurized.
• Always be certain spray gun, nozzles and accessories are
correctly attached.
2. Attach other end of high pressure hose to high pressure
outlet on pump. Tighten by hand.
