RULES FOR SAFE OPERATION  
NEVER touch the hot exhaust manifold,  
muffler or cylinder.Allow these parts to cool  
before servicing engine or pump.  
DANGER  
Failure to follow instructions in this manual may lead to  
serious injury or even death! This equipment is to be  
operated by trained and qualified personnel only! This  
equipment is for industrial use only.  
The following safety guidelines should always be used when  
operating the trash pump:  
HighTemperatures – Allow the engine to cool before adding  
fuel or performing service and maintenance functions. Contact  
with hot components can cause serious burns.  
GENERAL SAFETY  
DO NOT operate or service this equipment before  
readingthisentiremanual.  
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  
This equipment should not be operated by persons under 18  
years of age.  
NEVER operate this equipment without proper protective  
clothing, shatterproof glasses, steel-toed boots and other  
protective devices required by the job.  
serious damage to the  
pump or engine and may cause injury to people and property.  
Remember the pump's engine gives off DEADLY gases.  
NEVER operate this equipment when not feeling  
well due to fatigue, illness or taking medicine.  
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 this equipment under the influence or drugs or  
alcohol.  
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.  
Whenever necessary, replace nameplate, operation and  
safety decals when they become difficult read.  
ALWAYS check the machine for loosened threads or bolts  
before starting.  
Topping-off to filler port is dangerous, as it  
tends to spill fuel.  
ALWAYS wear proper respiratory (mask) hearing and eye  
protection equipment when operating the pump.  
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.

damage may occur.  
ALWAYS read, understand, and follow procedures in  
Operator’s Manual before attempting to operate equipment.  
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.  
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.  
Maintenance Safety  
NEVER leave the pump unattended, turn off engine when  
unattended.  
NEVER lubricate components or attempt service on a running  
machine.  
Unauthorized equipment modifications will void all  
warranties.  
ALWAYS allow the machine a proper amount of time to cool  
before servicing.  
NEVER pump volatile, explosive, flammable or low flash  
point fluids.These fluids could ignite or explode.  
Keep the machinery in proper running condition.  
Fix damage to the machine immediately and always replace  
broken parts, or missing decals.  
NEVER operate the pump in an explosive atmosphere.  
Before starting the pump, check that the clean-out cover is  
securely fasten.  
Dispose of hazardous waste properly.Examples of potentially  
hazardous waste are used motor oil, fuel and fuel filters.  
ALWAYS ensure pump is on level ground before use.  
DO NOT use food or plastic containers to dispose of  
hazardous waste.  
Become familiar with the components of the pump before  
operating.  
DO NOT pour waste, oil or fuel directly onto the ground,  
down a drain or into any water source.  
NEVER pump corrosive chemicals or water containing toxic  
substances. These fluids could create serious health and  
environmental hazards. Contact local authorities for  
assistance.  
Emergencies  
ALWAYS know the location of the  
nearest fire extinguisher.  
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.  
ALWAYS know the location of the nearest  
first aid kit.  
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.  
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 case of an  
emergency.  
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.

QP3TY — GENERAL INFORMATION  
Elevation  
APPLICATION  
Higher elevations will effect the performance of the pump. Due to  
less atmospheric pressure at higher altitudes, pumps DO NOT  
have the priming ability that they have at sea level.This is due to  
the “thinner air” or lack of oxygen at higher altitudes.  
The QP3TY Trash Pump is designed to be used for dewatering  
applications. Both the suction and discharge ports on the QP3TY  
trash pump use a 3-inch diameter opening, which allows the  
pump to pump at a rate of approximately 383 gallons/minute  
(gpm) or 1,450 liters/minute (lpm).  
A general rule of thumb is that for every 1,000 feet of elevation  
above sea level a pump will lose one foot of priming ability.  
Trash or self-priming pumps are designed to purge air from the  
suction line and create a partial vacuum in the pump body.The  
reduced atmospheric pressure inside the pump allows water to  
flow through the suction line and into the pump body. The  
centrifugal force created by the rotating impeller pressurizes the  
water and expels it from the pump.  
For example, in Flagstaff, Arizona where the elevation is  
approximately 7,000 feet, the pump would have a suction lift of  
25 feet rather than the 18 feet at sea level.Table 3 shows suction  
lift at various elevations.

Trash pumps derive their name from their ability to handle a  
greater amount of debris and solids than standard centrifugal  
pumps.This pump generally handle solids up to 1/2 the size of  
the discharge opening making them less likely to clog. Also trash  
pumps are capable of handling water with 25% solids by weight.

Table 4 shows percentage drops in performance as elevation

Suction Lift  
This pump is intended to be used for dewatering applications  
and is capable of suction lifts up to 25 feet at sea level. For  
optimal suction lift performance, keep the suction hose or line as  
short as possible. In general, always place the pump as close to  
the water as possible.

QP3TY — PUMP COMPONENTS  
Figure 2 shows a typical application using the QP3TY Trash pump. Please note that this pump is intended for the removal of clean  
water and water containing some debris and solids. Maximum size of solids should not exceed 1.5 inch (30 mm) in diameter. DO  
NOT set strainer on bottom of water bed. Placing the strainer above the water bed will prevent the pump from drawing in excessive  
amounts of sand and foreign debris.
