Dispose of empty mixing-oil canisters 
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 canister before fueling your 
machine.
The type and style of the harness 
depend on the market.
The use of the shoulder strap is

Fueling
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 fuel cap as 
securely as possible by hand.
