FUELING AND LUBRICATION
WARNING: Never smoke whilst refueling and avoid

The unit is equipped with 2-stroke engine. There -
fore, mixture of unleaded gasoline (of 89 octane or
higher) and 2-stroke oil must always be used. Use
only gasoline that does not contain any ethanol
or methanol. It is very important to pay attention
with the fuel mixture that you use, since accurate
mixture of oil and fuel must be obtained. Small
quantities of oil and fuel mixture with small inac-
curacies, can affect the ratio of mixture, which may
lead to engine overheat and serious damages in
the engine. It is recommended that you mix only
the amount needed for the job that you are about
to do, in order to keep only fresh mixture.
WARNING: Carefully open the tank top as pressure
could have formed inside.
Especially formulated 2-stroke oil for air cooled
2-stroke engines must be used. Do not use 2-stroke
