INTRODUCTION
1-1 Using Your Tsurumi Operation, Repair and Service Manual
We thank you for purchasing a Tsurumi trash pump. We are sure that the trash pump you have selected will meet your portable pumping needs.
This manual applies to the Tsurumi trash pumps listed below. Specifications for the trash pumps are
provided in the SPECIFICATIONS section. Key features of the trash pump are shown in the
DESCRIPTION section.
EPT3-50HA
EPT3-80HA
EPT3-100HA
This manual provides instructions for operation, service, and repair of your trash pump. We strongly
recommend that those who operate the trash pump become familiar with the trash pump’s features
and controls, and read the operating instructions before using the trash pump.
The Operation, Repair, and Service Manual also provides instructions to service, checkout, and repair
the trash pump. This manual also provides replacement parts information.
Repair and service information for the Honda engine is provided in the Owner’s Manual for Models
GX160, GX240, and GX340. A copy of the Owner’s Manual has been provided in the trash pump’s literature package. Parts information for the Honda Engine is available in Honda’s Parts Catalogs.
When there are differences between trash pump models, separate instructions are provided. The separate instructions are provided to make sure the correct procedures are used on the affected trash pumps.
All information in the Tsurumi manuals is based upon the latest production configuration of the trash
pump at the time of approval for printing.
If you have a problem with your trash pump that cannot be resolved using the Operation, Repair, and
Service Manual, or if you have questions about the operation, service, repair, or maintenance of your
trash pump, contact your local Tsurumi trash pump dealer.
1-2 Precautions
Pay special attention to precautionary notes preceded by the words WARNING, CAUTION, and
NOTE
.
W
ARNINGS indicate that there is a strong possibility of personal injury or loss of life if the procedure
is not followed, or if cleaning, lubricating, adhesives, and other materials are not used properly.
CAUTIONS
indicate that there is a possibility of equipment damage
if instructions are not followed.
NOTES
are used in procedures to provide additional or supplemental information to make the proce-
dure easier or more efficient.
W
ARNING:
• The trash pump is designed to give safe and dependable service when operated according
to the instructions in the technical manual provided with the trash pump.
• Do not operate the trash pump before you have read and understand the instructions and
the engine manufacturer’s manual. Failure to do so could result in personal injury or equipment damage.

Tsurumi’s Operation, Service, and Repair Manual
1-3 Safety Precautions
WARNING:
• IN ORDER TO ASSURE SAFE AND EFFICIENT OPERATION OF THE TRASH PUMP, OPERATOR’S SHOULD READ AND COMPLY WITH THE FOLLOWING SAFETY PRECAUTIONS.
• Do not operate the trash pump near gasoline or gaseous fuels because of the potential danger from explosion or fire.
• Do not fill the fuel tank with fuel while the engine is running. Be careful not to spill fuel during
refueling. If fuel is spilled, wipe it off and let it dry before starting the engine.
• Do not smoke or use open flame near the fuel tank.
• Do not place flammable materials near the trash pump. Be careful not to place fuel, matches,
gunpowder, oily cloths, straw, trash, or any other combustibles near the trash pump.
• Do not operate the trash pump inside a room, cave, tunnel, or other insufficiently ventilated
area. Always operate the trash pump in a well-ventilated area. The engine may become overheated, and the poisonous carbon monoxide gas contained in the exhaust gases will endanger human
lives.
• Keep the trash pump at least 1 meter (3 feet) away from any structure or building during use.
When a trash pump is located close to a building or nearby equipment, heat and exhaust from the
engine will cause the surrounding temperature to rise. This will degrade the engines cooling efficiency, causing overheating.
• Do not enclose the trash pump nor cover it with a box. The trash pump has a built-in, forcedair cooling system, and may become overheated if it is enclosed.
• Operate the trash pump on a level surface. It is not necessary to prepare a special foundation
for the trash pump. However, the trash pump will vibrate on an irregular surface. Therefore, choose
a level place without surface irregularities.
• Shutoff the trash pump when moving the trash pump to another work site. It the trash pump
is tilted or moved during operation, fuel may spill and/or the trash pump may tip over, causing a hazardous situation. Proper lubrication cannot be expected if the trash pump is operated on a steep
incline or slope. In such a case, the piston may seize; it may seize even if the oil is above the upper
level.

OPERATING INSTRUCTIONS
2-1 Operating Controls
A. The trash pump operating controls are located on the engine.
B. The controls consist of a throttle lever (for speed control), choke lever (for cold weather
starting), fuel shutoff lever (to prevent fuel spills), and a recoil starter (to turnover engine by
hand). (Refer to Figure 2-1.)
2-2 Check the Engine Oil Level
CAUTION:
• ENGINE OIL IS A MAJOR FACTOR AFFECTING PERFORMANCE AND SERVICE LIFE.
NON-DETERGENT OILS AND 2-STROKE OILS ARE NOT RECOMMENDED BECAUSE
THEY HAVE INADEQUATE LUBRICATING CHARACTERISTICS
• CHECK THE OIL LEVEL WITH THE ENGINE ON A LEVEL SURFACE AND THE ENGINE
STOPPED.
A. The trash pump is controlled by the engine operating controls.
B. Use Honda 4-stroke oil, or use an equivalent high detergent, premium quality motor oil cer-
tified to meet or exceed U.S. automobile manufacturer’s requirements for Service
Classification SG, SF. Motor oils classified SG, SF will show this designation on the container. SAE 10W/30 is recommended for general, all-temperature use.
C. Other viscosity grades shown in Figure 2-2 may be used when the average temperature in
your area is within the indicated range.
