Fuel mix ages
Only mix sufficient fuel for a few days 
work, not to exceed 3 months of storage. 
Store in approved fuel-containers only. 
When mixing, pour oil into the container 
first, and then add gasoline. Close the 
container and shake it vigorously by 
hand to ensure proper mixing of the oil 
with the fuel.
Dispose of empty mixing-oil containers 
only at authorized disposal locations.
Before fueling, clean the filler cap and 
the area around it to ensure that no dirt 
falls into the tank.
Always thoroughly shake the mixture in 
the can before fueling your machine.
In order to reduce the risk of burns or 
other personal injury from escaping gas 
vapor and fumes, remove the fuel filler 
cap carefully so as to allow any pressure 
build-up in the tank to release slowly.
After fueling, tighten down the filler cap 
by hand as securely as possible.
Change the fuel pickup body every year.
Before storing your machine for a long 
period, drain and clean the fuel tank.
