Fuel And Oil Recommendations; Adjustment Of The Throttle Cable - Cobra BC270KB Owner's Manual

4. Fuel and Oil Recommendations

Warning:
Petrol is extremely flammable and can be
explosive under certain conditions, creating the
potential for serious burns.
Turn the ignition switch to "OFF".
Do not smoke. Make sure the area is well-ventilated
and free from any source of flame or sparks; this
includes any appliance with a pilot light.
Never fill the tank completely to the top. If the tank is
filled completely to the top, heat may cause the fuel
to expand and overflow through the vents in the tank
cap.
After refuelling, make sure the tank cap is closed
securely. If petrol is spilled on the fuel tank, wipe it
off immediately.
Note: Running on petrol only will cause the
engine to seize. Use petrol-oil mixture.
Use petrol and engine oil mixing ratio: 50:1
(Petrol 50, 2-stroke engine Oil 1)
Note: Do not use any fuel that contains
more ethanol or other oxygenates than
specified for E10 fuel* in this engine.
Damage to the engine and fuel system, or engine
starting and/or performance problems may result
from the use of improper fuel.
*E10 means fuel containing up to 10% ethanol as
specified by European directive.

volume content not more than 10% and an octane
rating equal to or higher than that shown in the table.
Ethanol Content:
Minimum Octane Rating:
- Do not use petrol that has been stored longer than
two months.
