Check the General Condition of the Pump
• Look around and underneath the pump for signs of oil or gasoline
leaks.
• Remove any dirt or debris, especially around the engine, muffler,
and recoil starter.
• Look for signs of damage.
• Check that all nuts, bolts, screws, hose connectors, and clamps are
tightened.
• Keep the connecting rod cover in place while operating the pump.
Check the Suction and Discharge Hoses
• Check the general condition of the hoses. Be sure the hoses are in
serviceable condition before connecting them to the pump.
Remember that the suction hose must be of reinforced construction
to prevent hose collapse.
• Check that the sealing washer in the suction hose connector is in
good condition (page 12).
• Check that the strainer is in good condition and is installed on the
suction hose (page 12).
Check the Engine
• Check the oil level (page 8). To avoid the inconvenience of an
unexpected shutdown by the Oil Alert® system, always check the
engine oil level before startup.
• Check the air cleaner (page 9).
• Check the fuel level (page 11). Starting with a full tank will help to
eliminate or reduce operating interruptions for refueling.

OPERATION
PUMP PRECAUTIONS
Before operating the pump for the first time, please review
IMPORTANT SAFETY INFORMATION (page 2) and BEFORE
OPERATION (page 3).
For your safety, avoid starting or operating the engine in an enclosed
area, such as a garage. Your engine’s exhaust contains poisonous
carbon monoxide gas, which can collect rapidly in an enclosed area
and cause illness or death.
Do not pump drinking water. Pump only non-potable water, muddy
water, and water containing solids. Pumping flammable liquids, such
as gasoline or fuel oils, can result in a fire or explosion, causing
serious injury. Pumping sea water, beverages, acids, chemical
solutions, or any other liquid that promotes corrosion can damage the
pump.
Due to the pump diaphragm reciprocating motion, pump assembly
and hoses will move up and down and side-to-side during pumping.
This may cause the pump to walk or move around while pumping.
Depending on the surface conditions, pump hose length, and other
factors, it may be necessary to anchor the pump to limit pump
movement. During operation, observe pump movement and anchor
the pump frame and wheels as necessary.
• Attach anchored tie-down straps to the pump frame
• Place blocks in front and behind the wheels
• Try to locate the pump on level surface
While pumping, the suction hose may move out of the pumping
source and the discharge hose may move away from the pumping
destination. It may also be necessary to anchor hose ends to prevent
hose movement.
If there is no one to monitor the pump during operation, it is advisable
to anchor the pump to prevent unexpected movement.
Pump total dynamic discharge head is 50 feet. Total dynamic
discharge head includes static discharge head (discharge vertical
height) and head loss due to friction. Head loss makes it impractical
for the static discharge head to exceed 25 feet. Pumping to a static
discharge head greater than 25 feet can damage the pump. See the
Pump Performance Curve on page 19.
This diaphragm pump should never be run with the discharge output
shut off or restricted.
NOTICE
Due to pump movement during operation, connecting a rigid pipe to
the pump will cause pump damage. Always use flexible suction and
discharge hoses to prevent pump damage.
When water being pumped contains solids, the solids may get lodged
under the clappet valves, which will prevent the clappet valves from
closing completely. To maintain maximum pump performance, the
discharge hose should angle upward as it exits the pump.
DISCHARGE
HOSE
If the discharge hose must run across a roadway, the hose should
cross the roadway perpendicular to traffic flow. Also, heavy boards
should be placed next to the hose so the motor vehicle weight does
not shut off the discharge as vehicles cross over the hose.
BOARDS
DISCHARGE
HOSE
NOTICE
Pump case failure may result if the discharge output is shut off or
restricted. To avoid pump damage, do not restrict, shut off, or
momentarily stop the fluid flow from the discharge hose.
A rigid pipe should never be used with a diaphragm pump. Flexible
hoses must be attached to the pump. The suction hose must be noncollapsible. Never use hoses that are smaller than the suction or
discharge fittings size.
This pump requires a 3 inch inside diameter or greater hose. Using
rigid pipes or hoses that are too small will cause severe damage to
the diaphragm pump.
4
Driving over a discharge hose while the pump is running, or even
possibly when the pump is stopped, will most likely cause pump case
failure.
NOTICE
Collapsing the discharge hose will cause pump case and/or
diaphragm damage. To prevent pump damage, take the necessary
precautions to prevent the discharge hose from getting compressed
or collapsed.
During freezing weather, always drain the pump case after use. If
water is left in the pump case during freezing weather, the pump case
will break.
PUMP PREPARATION
Optional hose kits, designed specifically for this pump, are available
from your Honda dealer. See page 20.
Suction Hose Connection
If using a commercially available hose, ensure it is the same size or
larger than the suction port diameter (3 inches). To prevent the hose
from collapsing, use a hose that is reinforced with a non-collapsible
wall or braided wire construction.
Keep the pump as close as possible to the pumping liquid. Avoid hose
bends and sharp turns. Pump performance is best when the pump is
not far above the liquid level and the hose is kept straight.
Self-priming time is also proportional to the suction hose length. Using
a longer suction hose will increase the self-priming time.
Tighten the hose connector to the suction hose with a hose clamp to
prevent air leakage and loss of suction. Verify that the connector
sealing washer is installed and in good condition. A loosely connected
suction hose will reduce pump performance and self-priming ability.

Pump Priming
Pump priming is not required if the vertical distance from water to the
pump (suction head) is less than 16 feet. The suction head can be
increased to 24 feet if the pump is primed.
To prime the pump, remove the air cushion chamber cap. Grasp the
suction hose next to the suction fitting and lift the hose about 1 foot off
the ground. Lifting the suction hose will help to ensure the water goes
into the pump housing and not out the suction hose.
Pour about 1 gallon of water into the pump case through the air
cushion chamber. Lay the hose back on the ground, and reinstall the
air cushion chamber cap.

COUPLING
The strainer provided with the pump should be attached to the end of
the suction hose as shown.
Always install the strainer on the end of the suction hose before
pumping. The strainer will prevent debris from entering the pump that
can cause clogging, diaphragm and/or other pump damage.
Discharge Hose Connection
If using a commercially available hose, a short, large diameter hose
will provide lower fluid friction and improve pump output. A long or
small diameter hose will increase fluid friction and reduce pump
output. Never use a hose size smaller than the discharge port
diameter (3 inches).
NOTICE
If a discharge hose is used that has a smaller inside diameter than the
port size, the pump case may be damaged. To avoid pump damage,
always use the correct size hose.
Tighten the hose clamp to prevent the hose from disconnecting under
high pressure.
