4) Recoil starter
Pull the start knob gently until it is hard to pull (compression point). Then, return
the start knob, and pull it strongly. Never pull the rope to the full extension. Once
the start knob is pulled, never release your hand immediately. Hold the start
knob until it returns to its original point.
5) Warm-up operation
Continue warm-up operation for 2 to 3 minutes.
NOTE: In case of excessive fuel intake, remove the spark plug and pull the starter
handle slowly to remove excess fuel. Also, dry the electrode section of the
spark plug.
Caution during operation:
If the throttle lever is opened fully in a no-load operation, the engine speed is
increased to 10,000 min
-1
(rpm) or more. Never operate the engine at a higher
speed than required and at an approximate speed of 6,000 - 9,000 min
-1
(rpm).
B: Startup after warm-up operation
1) Repeat pushing the primer pump gently.
2) Keep the throttle lever at the idling position.
3) Pull the recoil starter strongly.
4) If it is difficult to start the engine, open the throttle by about 1/3.
Pay attention to the cutting blades which may move.
At times, such as winter, when starting the engine is difficult, operate choke
lever with the following procedure when starting engine.
• After implementing startup steps 1) to 3), set choke lever to the CLOSE position.
• Implement startup step 4) and start engine.
• Once engine starts, set choke lever to the OPEN position.
• Implement startup step 5) and complete warm up.
CAUTION: If a bang (explosive sound) is heard and the engine stops, or the
just-started engine stalls before the choke lever is operated, return the
choke lever to the OPEN position, and pull the starter knob a few times
again to start the engine.
CAUTION: If the choke lever is left in the CLOSE position, and the starter knob
merely pulled repeatedly, to much fuel will be sucked in, and the engine
will become difficult to start.
