Introduction and Safety
• Adequate, unobstructed flow of cooling and
ventilating air is critical to correct pump
operation. Do not alter the installation or
permit even partial blockage of ventilation
provisions, as this can seriously affect safe
operation of the water pump.
Fire Hazards
DANGER
Explosion and Fire. Fuel and vapors are
extremely flammable and explosive. Add fuel
in a well ventilated area. Keep fire and spark
away. Failure to do so will result in death
or serious injury.
DANGER
Explosion and Fire. Do not overfill fuel tank.
Overfilling may cause fuel to leak and ignite
or explode, resulting in death or serious injury.
• Wipe up any fuel or oil spills immediately.
Verify that no combustible materials are left
on or near the chemical pump.
• Reflective exhaust heat may damage the
fuel tank, causing fire. Keep at least five (5)
feet (152 cm) of clearance on all sides of
the pump for adequate cooling, mainte-
nance, and servicing.
• It is a violation of California Public
Resource Code, Section 4442, to use or
operate the engine on any forest- covered,
brush-covered,
unless the exhaust system is equipped with
a spark arrestor, as defined in Section
4442, maintained in effective working order.
Other states or federal jurisdictions may
have similar laws. Contact the original
equipment manufacturer, retailer, or dealer
to obtain a spark arrestor designed for the
exhaust system installed on this engine.
Fuel Hazards
DANGER
Explosion and Fire. Fuel and vapors are
extremely flammable and explosive. Add fuel
in a well ventilated area. Keep fire and spark
away. Failure to do so will result in death
or serious injury.
WARNING
Explosion and fire risk. Do not smoke near unit.
Keep fire and spark away. Failure to do so could
result in death, serious injury, or property or
equipment damage.
WARNING
Explosion and Fire. Do not smoke while
refueling unit. Failure to do so could result in
death, serious injury, or property or equipment
damage.
• Turn pump OFF and let cool at least two (2)
minutes before removing fuel cap. Loosen
cap slowly to relieve pressure in tank.

Before Starting Equipment
• There is no oil in the engine. The engine
crankcase must be filled before starting the
engine for the first time. See
Oil.
• Verify spark plug, muffler, fuel cap, and air
cleaner are in place.
• DO NOT crank engine with spark plug
removed.
• Keep your hands and body clear from the
discharge of the pump.
• Make sure all connections are tight.
• Secure the pump. Loads from the hoses
may cause it to tip over.
• Secure the discharge hose to avoid whip-
ping.
When Operating Equipment
Electrocution. Water contact with a power
source, if not avoided, will result in death
or serious injury.
Equipment and property damage. Do not operate unit on
uneven surfaces, or areas of excessive moisture, dirt, dust
or corrosive vapors. Doing so could result in death, serious
injury, property and equipment damage.
land
Personal injury. Keep out of reach of children.
Failure to do so could result in death or serious injury.
Personal injury and equipment damage. Do not use
equipment as a step. Doing so could result in fall,
equipment damage, unsafe equipment operation,
and could result in death or serious injury.
• DO NOT tip engine or equipment at angle
which causes fuel to spill.
• DO NOT pump flammable liquids, such as
fuel, or fuel oils.
• Secure the pump. Loads from the hoses
may cause it to tip over.
• Do not submerge the pump.
• DO NOT stop the engine by moving the
choke lever to the CHOKE position.
• Always run pump with liquid. Running a dry
pump will destroy the pump seal.
• Run pump with open valves to avoid over-
heating and pump failure.
• Run pump at full throttle to prevent engine
overheating.
• Do not add pressurized liquid from another
source to the inlet as this may cause pump
failure.
• Always use flexible non-collapsible hose.
Hard piping causes pump connection
stress and pump failure.
