14CAUTION : Observe the applicable accident prevention regulations!STARTINGWARNING: Pay attention that the cutting tool rotates immediately after engine starts. Make sure that the cutting tool has no contact with hardobjects such as branches, stones etc.CAUTION:– Move at least 3 m away from the place of refuelling. Place the unit on the ground taking care that the cutting tool does not come into contactwith the ground or any other objects.– Never pull the rope to the full extension. Once the starter knob is pulled, never release your hand immediately. Hold the starter knob until itreturns to its original point.A: Cold start1) Set this machine on a flat space.2) Grasp the handle (the safety lock-off (1) isreleased by the grasp).3) Press the throttle lever (2) and hold it down.4) Slide the I-O switch (3) to START (4). Itmakes the throttle lever become half-throttlelock state.POINTS IN OPERATION AND HOW TO STOP(1)(2)(3)(4)(1)(4)(2)(3)EM3400U EM3400L5) Give a gentle push on the primer pump (5) repeatedly (7-10 times) until fuelcomes into the primer pump.6) Move the choke lever (6) to the top position ( - closed choke).7) Firmly hold the unit by your left hand.8) Pull the starter knob gently until feeling compression. Then pull it strongly.9) Repeat the starting operation until initial ignitions are heard.10) When the engine starts, return the choke lever to “ - open choke”position.11) As soon as the engine starts, immediately grasp the handle (the safetylock-off is released by the grasp) and pull the throttle trigger for a little, andrelease it. (It releases the half-throttle lock state and the engine runs in idle.)12) Run the engine for approximately one minute at moderate speed beforeapplying full throttle.B: Warm start– Same as described above, except without moving the choke lever (choke lever remains “ - open choke” position).NOTE:In case of excessive fuel intake, remove the spark plug and pull the starter handle slowly to remove excess fuel. Also,dry the electrodesection of the spark plug.Caution during operation: If the throttle lever is opened fully in a no-load operation, the engine rotation is increased to 10,000 min -1 or more.Never operate the engine at higher speed than required. Operate the engine at an approximate speed of 6,000 - 8,000 min -1 .(5)(6)
