WARNING
Always use a safety petrol container. Do not smoke
when adding petrol to the fuel tank. Do not add
petrol when you are inside an enclosure. Before you
add petrol, stop the engine and let the engine cool
for several minutes.
1. Fill the fuel tank to the FULL position with regular
unleaded petrol (see Figure 17). Do not use pre-
mium unleaded petrol. Make sure the petrol is
fresh and clean. Leaded petrol will increase de-
posits and shorten the life of the valves.
2. Some models have a fuel shut-off valve (1) located
under the fuel tank (see F
igure 14). If equipped,
turn the fuel shut-off valve 1/4 turn to the OPEN po-
sition.
