TROUBLE SHOOTING

Feature of this model: “i-Start” ( RM-4000SI )
“i-Start” generates enough revolving power to rotate
crankshaft up to a speed to ignite the engine and bring
almost no kickback.
“i-Start” makes engine start far more easier than you
ever expect.
IMPORTANT
Stopping engine without returning to idling (low
speed revolution) may cause failure.
Except in case of emergency never fail to stop
engine after shifting to idling (low speed
revolution).
