INSTALLATION & OPERATION
3. Remove the fill cap/dipstick. Add oil until the level reaches
the bottom of the opening.
4. Check the oil level by pushing the cleaned dipstick into the
oil-fill opening without screwing it in. Remove dipstick and
inspect it. Add oil if needed. Reinstall the cap / dipstick.
The engine has a low-oil monitoring system. If the oil level
drops too low, the system will automatically turn off the
engine.
5. : DO NOT fill fuel tank when engine is running.
Check fuel level in tank. Do not over fill. Use fresh, clean
automotive fuel that has an octane rating of 86 or higher.
6. : PUMP MUST NOT BE RUN DRY. On self-
priming pumps, only the chamber needs to be filled with
liquid. The pump must not run without the priming chamber
completely filled with liquid as 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.
After use, the priming chamber should be flushed and drained
to avoid chemical corrosion and damage from freezing. Drain
by removing the lower drain plug located at the bottom of the
casing.
STARTING THE PUMP
1. Before starting engine, be sure the priming chamber is filled
with liquid and the discharge hose is secure.
2. Open the Fuel Valve by moving to the right which allows fuel
to the engine.
3. Move the Throttle (speed control) slightly to the left.
4. Choke: When starting a cold engine, move the choke
control to the left (closed). As the engine warms up, move
it towards the right (open). A warm engine should start with
the choke open.
5. Engine Switch: The engine switch controls the ignition.
Turn it to the “ON” position to start the engine.
6. Start engine by pulling recoil starter out quickly and
forcefully. Repeat pulling until the engine starts.
PUMP OPERATION
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 rpm to proper speed for your pumping
application.
STOPPING THE PUMP
1. Stop pump for a short time: Run engine throttled all the way
down (fully to the right). Turn engine switch to OFF position.
2. Stopping pump for storage:
Turn fuel cock to OFF position instead of turning the
engine switch off.
Let the engine idle for 2 to 3 minutes until fuel in
carburetor is depleted and engine stops. If a valve is
installed on the discharge hose, run pump with valve
closed during this procedure.
PUMP STORAGE
1. Drain pump. Flush pump after use to avoid gumming or
corrosion inside the pump.
Flush the pump and system with a solution that
chemically neutralizes the liquid pumped. Mix according
to manufacturer’s directions to dissolve most residues
remaining in the pump.
2. Drain all the fuel from the fuel tank, fuel lines, and filter.
3. Store pump in a clean, dry environment.
