FUELS/REFUELING
Handling fuel
Utmost care is required when handling fuel. Fuel may contain substances similar
to solvents. Refuel either in a well ventilated room or outdoors. Do not inhale fuel
vapors,avoidanycontactoffueloroilwithyourskin.
Mineral oil products degrease your skin. If your skin comes in contact with these
substancesrepeatedlyandforanextendedperiodoftime,itwilldesiccate.
Variousskindiseasesmayresult.Inaddition,allergicreactionsmayoccur.
Eyescanbeirritatedbycontactwithoil.Ifoilcomesintoyoureyes,immediately
washthemwithclearwater.Ifyoureyesarestillirritated,seeadoctorimmediately.
Fuel and oil mixture
The engine of the brush cutter is a high-efficiency two-stroke engine. It is run with
a mixture of fuel and two-stroke engine oil. The engine is designed for unleaded
regularfuelwithamin.octanevalueof91RON.Incasenosuchfuelisavailable,
youcanusefuelwithahigheroctanevalue.Thiswillnotaffecttheengine,butmay
cause poor operating behaviour.
A similar situation will arise from the use of leaded fuel. To obtain optimum engine
operationandtoprotectyourhealthandtheenvironment,onlyunleadedfuelshould
be used!
Forlubricatingtheengineuseatwostrokeengineoil(qualitygrade:TC3),whichis
added to the fuel. The engine has been designed to use specified two-stroke engine
oilatmixtureratioof50:1toprotecttheenvironment.Inaddition,alongservicelife
and a reliable operation with a minimum emission of exhaust gases is guaranteed.
It is absolutely essential to observe a mixture ratio of 50:1 (specified 2-stroke engine
oil),asotherwisereliablefunctionofthebrushcuttercannotbeguaranteed.
Observe the Safety Instructions on page 4.

recommended
Note: Forpreparingthefueloilmixturefirstmixtheentireoilquantitywithhalfof
thefuelrequired,thenaddtheremainingfuel.Thoroughlyshakethemixture
before filling it into the brush cutter tank. It is not wise to add more engine oil
than specified to ensure safe operation.
This will only result in a higher production of combustion residues which
will pollute the environment and clog the exhaust channel in the cylinder
aswellasthemuffler.Inaddition,thefuelconsumptionwillriseandthe
performance will decrease.
Refuelling
The engine must be switched off.
Thoroughlycleantheareaaroundthefuelfillercap(2),topreventdirtfrom –
getting into the fuel tank (1).
Unscrew the fuel filler cap (2) and fill the tank with fuel. –
Tightly screw on the fuel filler cap (2). –
Clean screw fuel filler cap (2) and tank after refueling. –
Storage of Fuel
Fuel cannot be stored for an unlimited period of time.
Purchase only the quantity required for a 4 week operating period. Only use
approved fuel storage containers.
