There are two motor and pump set-ups, both the motors are made by the same parent company, having only slightly differently design features, the main differences being the size of the fuel tanks, Motor-2 is a bit quieter (79dBA) and slightly different dry weight, other than that they use the same motor and pump.

NB: These low pollution motors have been designed to run a SPECIAL Fuel/Oil mixture ratio of up to 100:1, but you MUST use a special oil that is designed to be run this lean, DON'T just use any oil at 1:100 or you may damage the motor.

You should be able to obtainable a 100:1 Two-stroke oil from almost any Chain saw or Mower outlet, if not just use the best one you can find.

Try not to run a NEW motor to Hard until you have run for an hour or so, if you intend to work the motor hard and for long periods, I would suggest you increase the content of oil to 25:1 minimum.
