Excellent machine used to fell 1 year 50 30cm diameter cypress. It happened several times that of the engine has failed or refuses to start what is frustrating when we do not understand why: the 2 pods of the on / off switch must be on-insulated with electrical tape, otherwise they strike sparks each other (short circuit) and this renders the motor to ground. Recurring problem on this model. Once, too, one of two pods had jumped. The switch is easy to get out of its housing to check.
