Specific Safety Information for Gasoline
Engine Driven Pumps
1. Carefully read the instruction manuals supplied by
the engine manufacturer before attempting to assem-
ble/disassemble or operate the engine or any other
part. The “Warning” and “Caution” statements in this
manual signal potential hazardous conditions to the
operator or equipment. Know when these conditions
can exist. Take necessary steps to protect personnel
as well as equipment.
WARNING
Gasoline is a highly combustible fuel. Use it with care!
The improper use, handling and/or storage of gaso-
line can be dangerous. Help prevent accidents by
following these safety rules:
a. Use gasoline only as fuel, never as a cleaning fluid.
b, Always use an approved container to hold or store
gasoline. Never store gasoline in familiar containers
such as milk gallons or soda pop bottles.
c. Never store gasoline near a heater or an open
flame.
d. When storing or using gasoline, make sure
container is out of the reach of children.
e. Never add gasoline to a running or hot engine.
Spilled gasoline on a hot engine may cause a fire or
an explosion. Fill gasoline tank outdoors and wipe up
any spills.
f. Have a fire extinguisher nearby. Be sure extinguish-
er is in operating condition - check the pressure
gauge or indicator. Be familiar with its proper use.
Consult the local fire department for the correct type
of extinguisher for your application Extinguishers
rated ABC by the National Fire Protection Association
are appropriated for all applications.
g. On permanent installations, be sure all fuel
supplies have a positive shut-off valve. Fuel lines
must be of steel piping, adequately secured and free
from leaks. Do not use copper piping or flexible lines
as copper becomes hardened and brittle and will
break. Use black pipe on natural gas or gaseous
fuels, but not on gasoline or diesel fuels. Piping the
engine should be a suitable flexible line that is
compatible with the fluid.
Positively No Smoking!
2. Check engine oil, fuel levels and gear box oil levels
before initial startup each day. Stay away from mov-
ing parts due to the danger of becoming caught in
moving parts. Avoid loose jackets, shirts, sleeves and
ties. Make sure all nuts and bolts are secure. Keep
power shields and guards in place. If adjustment
MUST be made while the unit is running, use extreme
caution around hot manifolds, moving parts etc.
3. Do not work with this equipment when mentally or
physically fatigued.
4. Be careful not to touch the exterior of the engine,
especially the muffler and the area around it. It is hot
enough to be painful or cause injury.
5. To prevent accidental starting, always remove the
spark plug or disconnect and ground the spark plug
wire before working on the engine or the equipement
driven by the engine.
6. DO NOT RUN THE ENGINE IN AN ENCLOSED
AREA!!
Exhaust gases contain carbon monoxide, which is an
odorless and deadly gas that will cause death if
breathed too long. If equipment is located in an
enclosed area with an exhaust line to the outside,
regularly check the exhaust system for leaks. Be sure
the area is well ventilated.
7. If the gas engine is equipped with a spark arrester
screen in the muffler, it should be inspected for wear
periodically and replaced when necessary.
Specific Safety Information for Electric Motor
Driven Pump
1. This unit is not waterproof and is not intended to be
used in potentially wet locations. The motor is de-
signed to be used in a clean, dry location with access
to an adequate supply of cooling air. Ambient temper-
ature around the motor should not exceed 104° F
(40° C). For outdoor installations, motor must be pro-
tected by a cover that does not block air flow to and
around the motor. This unit is not weatherproof nor is
it able to be submersed in water.
2. When wiring an electrically driven pump, follow all
electrical and safety codes, as well as the most re-
cent United States National Electrical Code (NEC)
and the Occupational Safety and Health Act (OSHA).
WARNING
Risk of electrical shock! Never connect the green
(or green and yellow) wire to a live terminal
3. To reduce the risk of electric shock, the motor must
be securely and adequately grounded! This can be
accomplished by either (1) inserting plug (portable)
directly into a properly installed and grounded

Mudsucker Trash Pump
3-prong grounding-type receptacle (as shown in Fig-
ure 2); 2 permanently wiring the unit with a grounded
metal raceway system. (3) using a separate ground
wire connected to the bare metal of the motor frame,
or (4) other suitable means. The green (or green and
yellow) conductor in the cord is the grounding wire.
The motor must be securely and adequately ground-
ed for your protection against shock hazard. Where a
2-prong wall receptacle is encountered, it must be
replaced with a properly grounded 3-prong receptacle
installed in accordance with the National Electrcial
Code and local codes and ordinances. To ensure a
proper ground, the grounding means best be tested
by a qualified electrician. Use only 3-wire extension
cords that have 3-prong, grounding-type plugs and 3-
pole receptacles that accept the equipment plug.

4. All wiring should be performed by a qualified
electrician.
WARNING
An incorrect connection may cause an electric
short, produce an electrical shock or burn out the
pump motor, resulting in property damage and/or
personal injury.
5. Protect electrical cord from sharp objects, hot sur-
faces, oil and chemicals. Avoid kinking the cord. Re-
place or repair damaged or worn cords immediately.
6. Provide safety shields on all moving and electrical
parts to prevent personal injury.
7. Keep fingers and foreign objects away from ventila-
tion and other openings. Do not insert any objects

(Ref No A3).
e. Place handle (Ref No A35) under pump well.
f. Reinstall two hex nut and washer assemblies then
tighten.
2. Rotating suction / discharge ports (optional)
Refer to Figure A.W.P.
In some applications, it may be preferable to have
suction / discharge ports rotated 90° to be in line with
driver. If so, proceed as below:
a. Remove four hex cap screws (Ref No A9), hex
cap screws (Ref A13 & A14) from pump assem-
bly to separate pump well (Ref No A3) from pump
base (Ref No A8)
b. Rotate pump well 90 degrees clockwise so that
driver is positioned over top of discharge plate
(Ref No W7).
c. Be sure that pump well base and diaphragm (Ref
No P17) are aligned properly with one another.
Then reinstall four hex cap screws, hex nuts and
washer assemblies and tighten.
Gear Box Oil (Refer to Figure A, G)
3.Place pump on a level surface. Fill pump gear box
(ref No A1) with gear box oil before the pump is oper-
ated. Gear oil must meet requirements of API GL-5
and military specification MIL-L-2105B. Remove gear
box housing fill plug (Ref No G8). Remove level plug
(Ref No G5). Pour gear oil into gear box slowly until
oil comes out of level plug.
Warranty on this unit is void unless the gear box
is lubricated with appropriate gear oil listed
above. DO NOT OVERFILL!!!
Installation
NOTE: In any installation where property damage
can occur by pumps not operating due to power out-
ages, discharge line freezing or any other reason, a
backup system (s) and/or warning system (s) should
be used.
1. Place the pump on a level, solid foundation, locat-
ing it as close to the liquid as possible making the
suction line as short and direct as possible.
2. Install pipe nipples (Ref No A36) so the smoother
side of pipe end faces the suction and discharge
hose.
CAUTION
Maximum discharge head is 25 feet or 10.9psi. Oper-
ation over this head or pressure will cause pump to
stall and/or gearbox damage. Use only rigid hoses.
3. Attach suction piping to the suction inlet (ref No
W2) and discharge piping to the discharge outlet (Ref
No W7). The suction line should be positioned such
that there is a continual upward slope from the fluid
source to the pump. Avoid using loops or sections of
pipe or fittings, which might permit air to become
trapped.
NOTE: If hose is used, be sure to use reinforced
hose on both the suction and discharge. DO NOT
USE canvas or similar collapsible materials. NEV-
ER USE PIPE REDUCER; PIPE SIZE MUST BE
EQUAL TO OR LARGER THAN THE PUMP PORT
SIZE. Suction line must be airtight sot that air
cannot leak in and destroy priming vacuum. On a per-
manent installation where piping is used, always con-
nect a piece of flexible hose between pump and pip-
ing so pump is free to move slightly.
4. It is advisable to use a strainer. (Ref No W16) on
the inlet end of the suction hose or pipe. A properly
sized strainer is supplied with this unit and should be
used at all times to prevent damage. Keep the strain-
er clean. If possible, suspend it to keep it from being
clogged with muck., roots, debris or leaves. It is best
to keep hose free of kinks as they will restrict flow and
add excess loading to pump and gearing.
5. Gasoline Engine Units: Follow all instructions
in the engine manual before starting the engine. Fill
engine with oil, gasoline, etc.
Air Motor Units: Follow all instructions in the
air motor manual before starting unit.
Electric Motor Units: It is strongly recommend-
ed that this unit is plugged into a G.F.I. (Ground Fault
Interrupter) circuit. Consult your local electrician for
installation and availability.
6. Input RPM (to pump) - Input RPT must be between
1750 and 2750 RPM. Final pump speed will be 40
strokes/minute with a 1750RPM input and 60
strokes/minute RPM Input.

Mudsucker Trash Pump
Do not exceed 60 strokes per minute with the dia-
phragm pump.
Operation
Operate the diaphragm pump in an upright position
only.
1. This diaphragm pump is capable of priming “dry”
up to fifteen feet; it will prime much faster when it
is filled with clean water through priming cap (Ref
No W6). Primed, it can lift to 25 feet.
2. Activate unit following engine or air motor manual
turning unit on if electrical
CAUTION
Do not control discharge capacity with a valve or sim-
ilar device.
Clearing Jam Up
If large solids or an accumulation of sand or other
sediment becomes lodged in the pump well (Ref No
A3) preventing the plunger arm (Ref No A2) from
making a full stroke, the pump will either stall or the
crank (Ref No P5) will slip on the output shaft (Ref
No G8). The pump is designed to react this way to
prevent severe internal damage. If such a jam-up
does occur, the pump should be thoroughly cleaned
as described in “If Pump Stalls” within this section.
Refer to parts list and illustration for parts identifica-
tion.
CAUTION
If pump has stopped or stalled for any unknown rea-
son, clean out pump cavity thoroughly. Failure to
comply with the “caution” could result in damage to
crank (Ref No P5/P9), plunger arm (Ref No P1) or
other parts of assembly.
1. If pump stalls:
a. Remove handle (Ref No A35).
b. Remove four bolts (Ref No A9 & A10)
c. Clean obstruction & all debris from pump well
(Ref No A3).
d. Reassemble pump in reverse order of disas
sembly and return to service.
2. If Plunger Arm (Ref No P1) seizes and gear box
output shaft (Ref No G8) turns in crank (ref No P5):
a. Remove sheet metal guard (ref No A4) by loos
ening hand knob screws (Ref No A5)
b. Disassemble pump and clean as described in
Steps a thru d listed for stalled engine jam up.
c. Torque the crank lock screw (Ref No A6) to 70
foot pounds with an appropriate torque
wrench. See Figure 3.
d. Reassemble the pump in reverse order of disas-
sembly and return to service.
WARNING
Pump jamming with an over-torqued lock screw may
cause internal damage. Under torqueing may allow
the output shaft to spin and wear parts necessitating
replacement.
