[5] FUELLING
The Rotabroach drilling machine uses an oil-petrol mixture for fuel.
Warning
Petrol is an extremely flammable fuel.
Use extreme caution when handling petrol or fuel mix.
Do not smoke or bring any fire or flame near the fuel.
Ensure the fuel mix does not spill on to hot engine.
FUELLING INSTRUCTIONS
• Fuel your machine in a well-ventilated area, outdoors only.
• Always shut off the engine and allow it to cool before refuelling.
• Petrol vapour pressure may build up inside the gas tank of a two-cycle engine depending
on the fuel used, the weather conditions and the venting system of the tank. In order to
reduce the risk of burns or other personal injury from escaping gas vapour and fumes,
remove the gas cap on the STIHL product carefully so as to allow any pressure build-up
in the tank to release slowly. Never remove the fuel filler cap whilst the engine is
running,
FUEL MIX
• Prepare the mixture of brand name petrol and quality two-stroke engine oil in an
approved safety type canister. Pour in the oil first and then add the petrol.
• STIHL two-stroke engine oil is recommended. It is formulated specially for STIHL engines
and guarantees a long engine life.
• It is recommended that you always use unleaded petrol with a minimum octane number
of 90 ROZ(USA)/Canada: pump octane min. 87.
• Inferior quality petrol or oils may damage the engine, sealing rings, fuel lines or fuel
tank.
MIX RATIO
• With STIHL 50:1 two-stroke engine oil: 50 parts petrol to 1 part oil.
• With other branded two-stroke air cooled engine oils: 25 parts petrol to 1 part oil.
