2.2.2 California Proposition 65
2.2.3 Spark arresters
IMPORTANT!
State and local safety codes specify that, in certain locations, internal combustion engines that
use hydrocarbon fuels must be used with spark arresters.
A spark arrester is a device constructed of nonflammable materials specifically for the purpose of
removing and retaining carbon and other flammable particles from the exhaust flow of an
internal combustion engine.
Spark arresters are qualified and rated by the United States Forest Service. To comply with all
applicable laws regarding spark arresters, consult your local Health and Safety Administrator.
2.3 Storage and maintenance safety
■When not in use, store equipment in a clean, dry location out of the reach of children.
■Before storing:
❑Drain fuel
❑Drain water and fluids that could freeze
❑Drain fluids that contain solids that could settle or crystallize
❑Drain fluids that may leave a solid or sticky residue inside the pump
■ALWAYS keep the pump in proper running condition.
■Before servicing, ensure the power unit cannot be inadvertently started during service.
■ALWAYS fix damage to the pump immediately. Repair or replace broken or worn parts. Only use
parts from original manufacturer.
■Replace operation and safety decals when they become difficult read.
■Dispose of hazardous waste in accordance with all applicable codes and ordinances. Examples of
potentially hazardous waste include motor oil, fuel, and fuel filters.
❑NEVER use plastic or food containers to dispose of hazardous waste.
❑NEVER pour waste, oil, or fuel directly onto the ground, down a drain, or into any water
source.
WARNING
Health hazard.
Engine exhaust and some of its constituents are known
to the State of California to cause cancer, birth defects,
and other reproductive harm.

3 Operation
3.1 Before starting
3.1.1 Safety
Before operating the Voltmaster Trash Pump:
■Read and be familiar with this instruction manual.
■Read and follow all safety instructions (see Section 2.1, page 3).
■Read and follow instructions in the engine manufacturer’s documentation.
3.1.2 Flow considerations
■Ensure the power unit, pump, wiring, and piping installations are suitable for the fluid being
pumped and comply with all applicable codes and ordinances.
■DO NOT expose pump to extremes conditions of acidity or basicity. If necessary, consult factory
for specific recommendations regarding chemicals and temperatures.
■Drain the pump whenever there is a danger of freezing.
■Overheating can occur if either the suction or discharge becomes restricted. If flow becomes
restricted, refer to Section 4, Troubleshooting, page 9.
■Before operating, ensure pump is on a firm, flat, level surface.
■If pump is located next to a pit or hole, ensure pump is anchored so that it cannot fall in.
■Locate pump as close to the level of the fluid to be pumped, but never higher than 25 feet (7.5m)
above fluid surface.
■Keep hoses and piping straight and as short as possible, avoiding sharp bends.
■If hoses must be laid across a roadway, protect it with planking. Instantaneous shutoff pressure,
applied when a vehicle runs over an unprotected hose, will cause “hydraulic shock” and may
damage the pump.
■If the discharge line runs vertically more than 30 feet (9m), it is advisable to install a check valve in
the discharge line, near the pump, to stop destructive liquid hammer when the pump is shut
down.
❑If a check valve is installed, it may be necessary to vent the top of the pump so that air can be
expelled during automatic priming. This can be accomplished by providing a 1/4-inch
(0.5cm) line from the top of the pump back to the fluid source.
❑If a check valve is not installed, the manufacturer cannot assume responsibility for damage
to the pump due to destructive liquid hammer.
CAUTION
An overheated pump can be extremely hot, resulting
in severe burns.
Stop pump immediately if overheating occurs. Then,
slowly and with great caution, vent pump at drain plug.

Voltmaster Trash Pumps
3.1.3 Installation
1. Install a suction strainer at the suction hose or pipe:
■A strainer is provided with holes or slots small enough to prevent larger particulate matter
from entering and damaging the pump. The strainer should be installed into the suction
end of the line, before piping enters the pump.
■The strainer should be positioned so it will remain completely under water. Running the
pump with the strainer above water for long periods can damage the pump.
■If possible, suspend the strainer to keep it from working into the sediment. Alternatively, set
the strainer on a bed of stones or tie it inside a basket or pail.
■During operation, the strainer should be kept clean to optimize flow.
2. Make plumbing connections to the pump using at least 12 inches (30cm) of flexible hose.
■Rigid piping may put stresses on the pump, resulting in damage to equipment. If rigid
piping is necessary, properly support the piping to eliminate stresses on the pump.
■Use sealant on all threaded connections.
■Ensure connections, drain, and filter plugs are tight but not overtightened. Excessive force
on connections may damage threads or the pump body.
■Ensure proper connection of hose and piping. Air leaks in the suction line may prevent
priming and reduce pumping capacity.
3. Fill the pump with liquid through the priming port on top of the pump.
■DO NOT run pump dry. Always fill the pump body with water before starting.
■The pump is self-priming when filled with water.
4. Prepare for starting the engine:
a. Observe all engine safety precautions in Section 2.2, page 4.
b. Check engine oil, fuel, and coolant levels. Use proper fuel.
c. If the fuel tank was drained or run dry, it might be necessary to prime the fuel lines. Refer to
the engine manual for instructions.
3.2 Operating the pump
1. Before operating the pump, follow all instructions in Section 3.1.
2. Start the engine, referring to engine manufacturer’s instructions if necessary.
3. To manage the flow, refer to the following sections.
3.2.1 Priming time
■At sea level, with a suction lift from 5 to 10 feet (1.5 to 3 meters), the pump should discharge fluid
in less than 1minute. A suction lift of up 25 feet (7.6m) requires less than 2 minutes.
■Priming time will increase with increased elevation above sea level.
■To reduce priming time, the engine speed may be increased (after the engine is properly broken
in; see engine documentation).
■If fluid is not flowing within the time specified above, shut off the pump and check plumbing to
determine whether the flow line is the problem. See Section 4, Troubleshooting.
3.2.2 Flow control
On high suction lifts, engine speed must be increased. On shallow lifts or when there is little fluid
to be pumped, fuel usage may be reduced and engine life increased may be by lowering the
engine speed. Refer to the engine documentation for additional information.

4 Troubleshooting
4.1 Common problems
For troubleshooting, check and resolve the following issues as needed. Contact the factory for
assistance if necessary (see Section 1.2, Where to obtain service, page 1).
If the pump fails to prime:
■The priming chamber might be empty or not sufficiently full
■Liquid in priming chamber might be overheated
■The direction of rotation might be reversed
■Rotation speed might be too slow
■The impeller or volute might be worn or broken
■Delivery line might be under pressure
■There could be air leaks in the suction-line or at joints in the line, loose screws at joints in the line,
or broken hoses in the line
■There could be an air leak through a damaged mechanical seal
■Quick-coupling gaskets might be broken or improperly mounted
■Hose clamps might be loose or broken
If capacity is low:
■The suction strainer might be clogged
■The suction or delivery line might be obstructed
■There could be high-friction losses in the suction line, which may require eliminating bends in
the line or restrictions from valves
■The suction lift could be too high
■The rotation speed might be too slow
■The impeller might be clogged
