Before use

5.1 Fuel
The two-stroke engine runs on a mixture of gasoline and oil. The quality of the fuel mixture decisively
influences the running and life expectancy of the engine.
DANGER
Risk of fire and explosion. Gasoline vapors are highly flammable.
▶ Never smoke while refueling.
▶ Don't refuel the product at the area where you are working (move at least 3 meters (10 feet) away from
the working area).
▶ Don't refuel the product while the engine is running. Wait until the engine has cooled down.
▶ Make sure there are no naked flames or sparks that could ignite the gasoline vapors.
▶ Take care to avoid fuel spillage. If fuel is spilled, clean up the areas affected immediately.
▶ Check to ensure there is no leakage from the fuel tank.
CAUTION
Risk of injury. The inhalation of gasoline vapors and skin contact with gasoline may be hazardous to the
health.
▶ Avoid direct skin contact with gasoline. Wear protective gloves.
▶ If your clothing becomes soiled with gasoline, it is essential to change your clothing.
▶ Ensure that the workplace is well ventilated in order to avoid breathing in gasoline fumes.
▶ Use a fuel container that complies with the applicable regulations.
Alkylate gasoline does not have the same density (specific weight) as conventional gasoline. To avoid
damage when alkylate gasoline is used, the engine settings must be readjusted by Hilti Service.
Alternatively, the oil content can be increased to 4% (1:25).
5.1.1 Gasoline
▶ Use regular or super gasoline with an octane rating of at least 89 ROZ.
The alcohol content (e.g. ethanol, methanol or others) of the fuel used must not exceed 10%,
otherwise the life expectancy of the engine will be greatly reduced.
5.1.2 Two-stroke oil
▶ Use good-quality two-stroke oil for air-cooled engines that meets at least the API TC specification.
