6. OPERATING YOUR ENGINE
(See Fig. 󱯔)
1. STARTING
(1) Open the fuel valve. (See Fig.󱯔-①)
(2) Turn the STOP SWITCH to the position “ I ” (ON).
(See Fig.󱯔-②)
(3) Set the speed control lever 1/3 of the way towards the high
speed position. (Except EX30) (See Fig.󱯔-③)
(4) Close the choke lever. (See Fig.󱯔-④)
■
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.󱯔-⑤)
2. RUNNING
(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.󱯖-①)
(2) Gradually move the speed control lever toward the high
speed position (H) and set it at the required engine speed.
(See Fig.󱯖-②)
■ 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
(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.󱯘-①)
(2) Turn the STOP SWITCH (or KEY SWITCH) counterclock-
wise to the position “○” (OFF). (See Fig.󱯘-②)
(3) Close the fuel valve. (See Fig.󱯘-③)
(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.󱯘-④)
※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.
(6) After starting the engine, gradually open choke by turning
the choke lever and fi nally 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.󱯔-⑥)
FOR ELECTRIC STARTER MODELS.
Insert the key into the key slot and set it at the “ I ” (ON)
position. Turn it to the right (START position) to start the
engine. (See Fig.󱯔-⑤)
■
Do not operate the electric starter continuously for more
than 5 secounds, even if the engine dose not start.
■
If the engine failed to start, set the key to the “ I ” (ON)
position and wait for about 10 secounds before retrying.
■
Never turn the key switch to the START position while
engine is running.
