QP-305SLT — SAFETY MESSAGE ALERT SYMBOLS
Safety precautions should be followed at all times when operating
this equipment. Failure to read and understand the Safety
Messages and Operating Instructions could result in injury to
yourself and others.
FOR YOUR SAFETY AND THE SAFETY OF OTHERS!
This Owner's Manual has been
developed to provide complete
instructions for the safe and
efficient operation of the Multiquip
Model QP-305SLT High
Pressure Centrifugal Pump.
Refer to the engine manufacturers
instructions for data relative to its
safe operation.
Before using these pumps, ensure that the operating
individual has read and understands all instructions in this
manual.
SAFETY MESSAGE ALERT SYMBOLS
The three (3) Safety Messages shown below will inform you
about potential hazards that could injure you or others. The
Safety Messages specifically address the level of exposure to
the operator, and are preceded by one of three words: DANGER,
WARNING, or CAUTION.
HAZARD SYMBOLS
Engine exhaust gases contain poisonous
carbon monoxide. This gas is colorless and
odorless, and can cause death if inhaled.
NEVER operate this equipment in a confined
area or enclosed structure that does not
provide ample free flow air.
Potential hazards associated with the QP-305SLT Centrifugal
Pump operation will be referenced with Hazard Symbols which
appear throughout this manual, and will be referenced in
conjunction with Safety Message Alert Symbols.
GASOLINE is extremely flammable, and its
vapors can cause an explosion if ignited. DO
NOT start the engine near spilled fuel or
combustible fluids. DO NOT fill the fuel tank
while the engine is running or hot. DO NOT
overfill tank, since spilled fuel could ignite if it
comes into contact with hot engine parts or
sparks from the ignition system. Store fuel in
approved containers, in well-ventilated areas
and away from sparks and flames. NEVER
use fuel as a cleaning agent.
Explosive Fuel
Lethal Exhaust Gases
Burn Hazards
Engine components can generate extreme heat.
To prevent burns, DO NOT touch these areas
while the engine is running or immediately after
operations. Never operate the engine with heat
shields or heat guards removed.
Rotating Parts
NEVER operate equipment with covers, or
guards removed. Keep fingers, hands, hair and
clothing away from all moving parts to prevent
injury.
NOTE

QP-305SLT — RULES FOR SAFE OPERATION
■ ALWAYS refuel in a well-ventilated area, away from sparks
and open flames.
■ ALWAYS use extreme caution when working with flammable
liquids. When refueling, stop the engine and allow it to cool.
■ DO NOT smoke around or near the machine.
Fire or explosion could result from fuel vapors,
or if fuel is spilled on a hot engine.
■ NEVER operate the pump in an explosive
atmosphere
or near combustible
materials. An explosion or fire could result
causing severe
bodily harm or even
death.
■ Topping-off to filler port is dangerous, as it
tends to spill fuel.
■ Refer to the Engine Owner's Manual for engine technical
questions or information.
■ NEVER use accessories or attachments, which are not
recommended by Multiquip for this equipment. Damage to
the equipment and/or injury to user may result.
■ Manufacturer does not assume responsibility for any accident
due to equipment modifications.
■ NEVER touch the hot exhaust manifold,
muffler or cylinder. Allow these parts to
cool before servicing engine or pump.
■ The engine of this
pump requires an
adequate free flow of
cooling air.
NEVER!
operate the pump in
any enclosed or
narrow area where free
flow of the air is
restricted. If the air flow
is restricted it will cause serious damage
to the pump or engine and may cause injury to people and
property. Remember the pump's engine gives off DEADLY
gases.
■ High Temperatures – Allow the
engine to cool before adding fuel or
performing service and maintenance
functions. Contact with
hot
components can cause serious burns.
The following safety guidelines should always be used when
operating the
centrifugal pump :
GENERAL SAFETY

QP-305SLT TRASH PUMP — OPERATION & PARTS MANUAL— REV. 0 (03/22/05) — PAGE 9
■ High Temperatures – Always stop engine and allow the
engine to cool before adding fuel, oil or performing service
and maintenance functions. Contact with
hot components can
cause serious burns.
■ NEVER disconnect any "emergency or safety devices" .
These devices are intended for operator safety. Disconnection
of these devices can cause severe injury, bodily harm or even
death! Disconnection of any of these devices will void all
warranties.
Maintenance Safety
■ NEVER lubricate components or attempt service on a running
machine.
■ ALWAYS allow the machine a proper amount of time to cool
before servicing.
■ Keep the machinery in proper running condition.
■ Fix damage to the machine immediately and always replace
broken parts, or missing decals.
■ Dispose of hazardous waste properly. Examples of potentially
hazardous waste are used motor oil, fuel and fuel filters.
■ DO NOT use food or plastic containers to dispose of
hazardous waste.
■ DO NOT pour waste, oil or fuel directly onto the ground,
down a drain or into any water source.
Emergencies
■ ALWAYS know the location of the
nearest
fire extinguisher .
■ ALWAYS know the location of the nearest
first aid kit .
■ In emergencies always know the location of the
nearest phone or
keep a phone on the job site .
Also know the phone numbers of the nearest
ambulance , doctor and fire department . This
information will be invaluable in the case of an
emergency.
■ NEVER Run engine without air cleaner. Severe engine
damage may occur.
■ ALWAYS read, understand, and follow procedures in
Operator’s Manual before attempting to operate equipment.
■ ALWAYS be sure the operator is familiar with proper safety
precautions and operation techniques before using pump.
■ ALWAYS store equipment properly when it is not being used.
Equipment should be stored in a clean, dry location out of the
reach of children.
■ NEVER leave the pump unattended, turn off engine when
unattended.
■ Unauthorized equipment modifications will void all
warranties.
■ NEVER pump volatile, explosive, flammable or low flash
point fluids.These fluids could ignite or explode.
■ NEVER operate the pump in an explosive atmosphere.
■ Before starting the pump, check that the clean-out cover is
securely fasten.
■ ALWAYS ensure pump is on level ground before use.
■ Become familiar with the components of the pump before
operating.
■ ALWAYS replace any worn or damaged warning decals.
■ NEVER pump corrosive chemicals or water containing toxic
substances. These fluids could create serious health and
environmental hazards. Contact local authorities for
assistance.
■ NEVER open the priming plug when pump is hot. Hot water
inside could be pressurized much like the radiator of an
automobile. Allow pump to cool to the touch before loosening
plug.
■ NEVER open the pump housing during operation or start the
pump with the clean-out cover removed.The rotating impeller
inside the pump can cut or sever objects caught in it.
■ NEVER block or restrict flow from discharge hose. Remove
kinks from discharge line before starting pump. Operation
with a blocked discharge line can cause water inside pump
to overheat.
■ ALWAYS fill the pump casing with water before starting the
engine. Failure to maintain water inside the pump housing
will cause severe damage to the pump.
■ In winter drain water from pump housing to prevent freezing.
