1. Always drain and flush pumps before servicing or
disassembling for any reason.
Preliminary to Mounting
Before setting up the pump for operation, check to
see that the motor and pump turn freely by hand. If it
cannot be turned over by pulling on the recoil starter,
open casing to check for obstructions lodged in pump.
Selecting the Suction Line
To get full capacity of the pump, the suction line should be
the same size as the pump suction port. If suction hose is
longer than approximately 6 feet, use next size larger hose.
The suction line must be free of air leaks. All joints and
connections of the suction line must be tightened securely
so that no additional air may enter the suction side through a
Preparations before Starting the Engine
1. Fuel: Check fuel level in tank. Do not over fill tank.
Use fresh, clean automotive fuel. Note: DO NOT FILL
FUEL TANK WHEN ENGINE IS RUNNING.
2. Engine Oil: Before checking or refilling with engine
oil, make sure the engine is stopped and placed
on a stable, level surface. Use oil recommended
for ambient air temperatures that the engine will be
running at. See chart below. Change oil according to
manufacturer's recommendation. (Once after the first
20 hours and every 100 hours thereafter.)

3. Priming Water: IMPORTANT: PUMP MUST NOT BE
RUN DRY. On self-priming pumps, only the chamber
needs to be filled with liquid. The pump must not run
unless the priming chamber is completely filled with
liquid because there is a danger of damaging the
mechanical seal, which depends on the liquid for its
lubrication.
Self-priming models can be primed by removing the
filler cap, located at the top of the pump where the
discharge line is mounted to the pump, and filling the
priming chamber with liquid. The priming chamber will
fill to the level of the inlet port. After use, the priming
chamber should be flushed and drained to avoid

2. Before returning unit for repair, drain out all liquids and
flush unit with neutralizing liquid. Then, drain the pump.
Attach a tag or include a written notice certifying that
this has been done.

loose connection. Use a good grade of suction hose that will
not collapse.
Basket Strainer
The basket strainer supplied with this pump
is to be used when transferring solutions that
may contain debris and solids which could
become lodged in the pump or damage the
impeller. Because of the high flow capacity
of this pump, unknown debris could be
siphoned off the bottom of the tank. Install the strainer on the
suction side of the pump whenever possible to avoid pump
damage.
chemical corrosion and damage from freezing. Drain by
removing the lower drain plug located at the bottom of
the casing.
Starting the Pump
IMPORTANT: Before starting engine, be sure the
priming chamber is filled with liquid and the discharge
hose is secure.
1. Turn engine switch located by recoil starter to ON
position.
2. Turn the fuel cock to ON.
3. Push the throttle lever to a slightly open position.
4. Operation of choke lever.
When engine is cold:
In cold weather, start engine with choke in fully
closed position.
In warm weather, start engine with choke in half-
closed position.
When engine is warm:
Start engine with choke in fully open position.
5. Start engine by pulling recoil starter out quickly and
forcefully. Repeat pulling until the engine starts.
Operation of the Pump
1. Idle the engine for 3 to 5 minutes to warm it up.
2. Open the throttle lever to the upper zone after engine
has warmed up.
3. Once the pump has primed, you will note a load on
the engine; adjust RPMs to proper speed for your
pumping application.
