Suction head in the fuel tank
The fuel filler (5) of the suction head is used to filler the fuel required by the –
carburetor.
A periodical visual inspection of the fuel filter is to be conducted. For that purpose –
openthetankcap,useawirehookandpulloutthesuctionheadthroughthetank
opening.Filtersfoundtohavehardened,beenpollutedorcloggeduparetobe
replaced.
Insufficient fuel supply can result in the admissible maximum speed being –
exceeded. It is therefore important to replace the fuel filter at least quarterly to
ensure satisfactory fuel supply to the carburetor.

Check of muffler exhaust port (6) regularly. –
Ifitiscloggedbycarbondeposits,carefullyscratchthedepositsoutwitha –
