4.2.2 Fuel
The engine requires a mixture of gasoline and engine oil. Unsuitable fuels or a mixing ratio that deviates from
the specification can lead to severe engine damage. The engine, seals, fuel lines and fuel tank may be
damaged if poor quality gasoline or engine oil is used. Use only high-quality gasoline with an octane rating of at
least 90 ROC - leaded or unleaded.
For reasons of health and for environmental reasons unleaded petrol is to be preferred. If fuel with an octane
number below 90 RON is used, glow ignition (causing "pinging" in the engine) and a rise of temperature may be
the result. This in turn can lead to damage to the driving mechanism on account of "piston jamming".
Mixing fuel
For preparing the fuel mixture only branded two-stroke engine oils are allowed! We particularly recommend the
STIHL-two-stroke engine oil 1:50; this oil is specifically blended for use in STIHL-engines. Mixing ratio: with
STIHL 1:50 two-stroke engine oil: 1:50, 1 part oil + 50 parts petrol, with other branded two-stroke engine oils
classification TC: 1:25, 1 part oil + 25 parts petrol.
When preparing the mixture, first fill in oil, then petrol.
Storing fuel mixture
Fuel mixture ages! Mix only as much as needed for a few weeks! Store in approved safety fuel canisters only in
a dry, cool and secure place protected against light and sunlight.
Do not store fuel mixture for longer than three months. The fuel mixture can become unusable faster if exposed
to light, sunlight or low or high temperatures. Fuel mixture that stagnates for a longer time unmixes. Therefore
shake the can containing the fuel mixture well before you fill it up again.
The fuel tank and the canister in which fuel mixture is stored should be cleaned thoroughly from time to time.
Residual fuel and the liquid used for cleaning must be disposed of in accordance with regulations and without
harming the environment!
Refuelling
Before refuelling stop the engine. Do not refuel as long as the engine is hot - fuel can overflow - fire hazard!
Open the fuel cap carefully so that overpressure is slowly reduced and no fuel spurts out.
Refuel only at well-ventilated places. If some fuel was spilled, immediately clean the motorized equipment - let
no fuel get in contact with your clothing, otherwise change your clothes immediately.
Thus the risk is reduced that the fuel cap unscrews on account of the vibration of the engine and fuel runs out.
Pay attention to leaks - if fuel runs out, do not start the engine - Danger to life on account of burns!
Attention: Avoid direct skin contact with and breathing in of gasoline fumes!
Attention: Pressure can build up insie the canister - open carefully!
Attention: Petrol is extremely flammable - keep it away from open fire - do not spill any fuel
- do not smoke!
Attention: After re-fuelling tighten the screw cap as tightly as possible.
