4. OPERATING YOUR PUMP

1.STARTING (See Fig. 3)

(1)Open the fuel valve. (See Fig.3-q)

(2)Turn the STOP SWITCH to the position “ I ” (ON). (See Fig.3-w)

(3)Set the speed control lever 1/3 of the way towards the high speed position. (See Fig.3-e)

(4)Close the choke lever. (See Fig.3-r)

■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.3-t)

(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 temperature is low, because the engine may stop. (See Fig.3-y)

2.RUNNING (See Fig. 4)

(1)After the engine starts, set the speed control lever at the low speed position (L) and warm it up without load for a few minutes.

(See Fig.4-q)

(2)Gradually move the speed control lever toward the high speed position (H) and set it at the required engine speed. (See Fig.4-w)

■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. 5)

(1) Set the speed control lever at the low speed position and

ENGLISH

(2) Turn the STOP SWITCH counterclockwise to the position

allow the engine to run at low speed for 1 or 2 minutes

 

before stopping.

 

(See Fig.5-q)

 

“ ◯ ” (OFF). (See Fig.5-w)

 

(3) Close the fuel valve. (See Fig.5-e)

 

(4) Pull the starter handle slowly and return the handle to its

 

original position when resistance is felt. This operation is

 

necessary to prevent outside moist air from intruding

 

into the combustion chamber. (See Fig.5-r)

 

※STOPPING ENGINE WITH THE FUEL VALVE

Close the fuel valve and wait for a while until the engine stops. Avoid to let the fuel remain in the carburetor over long periods, or the passages of the carburetor may become clogged with impurities, and malfunctions may result.
