exhaust, become extremely hot. Keep sufficient distance from hot surfaces and keep children away
from the running motor.
When refilling or draining the fuel, use a gasoline-approved container in a clean, well-ventilated
area. Smoking, sparks, open flames or other sources of ignition are not allowed in the vicinity and
when filling the fuel. Filling the fuel tank in a closed room is not permitted. Keep grounded,
conductive objects such as tools, clear, current-conducting lines, and connectors away to avoid
sparks or arcs. These can ignite gas or vapors.
Before refilling the fuel, always turn off the engine and let it cool down. Never remove the fuel
cap and fill fuel when the engine is running or is still hot. In the case of leaking fuel lines, the
machine must not be put into operation.
Carefully loosen the tank lid so that the existing pressure in the tank can slowly degrade.
Do not overflow the fuel tank (there should be no fuel above the upper limit mark). Use
appropriate filling aids.

Screw the tank lid onto the fuel tank. immediately wipe the spilled fuel. Never operate the device
without the tightly screwed-on tank lid.
There should be no ignition source near spilled fuel. If fuel is spilled, remove the machine from
there. Do not attempt to start the engine and avoid any ignition source until the fuel fumes are
discharged.
Store the fuel only in containers that are specially approved for this purpose.
Store the fuel in a cool, well-ventilated area, away from heat, open flame and ignition sources.
Fuel, or the engine with fuel in the tank, should never be stored inside a building where it can
come into contact with sparks, an open flame or any other source of ignition, such as water
heaters, ovens, tumble dryers and the like. The engine should cool down before the machine is
stored in a closed room.
