It is recommended that the water chamber of pump
casing should be primed with full of water before
operating.
WARNING
Never attempt to operate the pump without
priming water or the pump will overheat.
Extended dry operation will destroy the
mechanical seal.
If the unit has been operated dry, stop the
engine immediately and allow the pump to
cool before adding priming water.

4. OPERATING YOUR PUMP

1. STARTING (See Fig.
(1) Open the fuel valve. (See Fig.
(2) Turn the STOP SWITCH to the position " I " (ON).
(See Fig. - )
(3) Set the speed control lever 1/3 of the way towards
the high speed position. (See Fig.
(4) Close the choke lever. (See Fig.
■ If the engine is cold or the ambient temperature is
low, close the choke lever fully.
■ If the engine is warm or the ambient temperature
is high, open the choke lever half-way, or keep it
fully open.
(5) Pull the starter handle slowly until resistance is felt.
This is the "compression" point. Return the handle
to its original position and pull swiftly. Do not pull out
the rope all the way. After starting the engine, allow
the starter handle to return to its original position
while still holding the handle. (See Fig.
(6) After starting the engine, gradually open choke
by turning the choke lever and finally keep it
fully opened. Do not fully open the choke lever
immediately when the engine is cold or the ambient

at the low speed position (L) and warm it up without
load for a few minutes. (See Fig.

high speed position (H) and set it at the required
engine speed. (See Fig.
■ Whenever high speed operation is not required,
slow the engine down (idle) by moving the speed
control lever to save fuel and extend engine life.
3. STOPPING (See Fig.
(1) Set the speed control lever at the low speed
position and allow the engine to run at low speed
for 1 or 2 minutes before stopping. (See Fig.
(2) Turn the STOP SWITCH counterclockwise to the
position " " (OFF). (See Fig.
(3) Close the fuel valve. (See Fig.
(4) Pull the starter handle slowly and return the handle

operation is necessary to prevent outside moist air
from intruding into the combustion chamber.

STOPPING ENGINE WITH THE FUEL VALVE
