Safety during the operation of combustion engines
Checking for signs of damage
Check the engine while switched off for leaks and cracks in the fuel line, tank and fuel cap at least once
per work shift.
Do not operate the machine if there is visible damage or defects.
Have any damage or defects eliminated immediately.
Dangers during operation
Combustion engines can be dangerous, particularly during operation and when refueling.
Read and follow all safety instructions. Otherwise there is a risk of personal injury and/or damage to
property!
Do not start the engine near spilt fuel or if you smell fuel – this may cause an explosion!
Remove the machine from such areas.
Remove the spilt fuel immediately!
Not changing the engine speed
Do not change the preset engine speed, as this may cause engine damage.
Preventing fires
Open flames and smoking are strictly prohibited in the immediate vicinity of the machine.
Make sure that waste, such as paper, dry leaves or grass do not accumulate around the exhaust muffler.
The waste materials may ignite.
Safety precautions when refueling
Please observe the following safety-relevant instructions when refueling:
Do not refuel near open flames.
Do not smoke.
Turn off the engine before refueling and allow it to cool down.
Refuel in a well-ventilated environment.
Wear fuel-proof protective gloves and, if there is the possibility of spraying, protective goggles and
clothing.
Do not inhale fuel vapors.
Avoid skin and eye contact with fuel.
For refueling, use clean tools such as a hopper.
Do not spill fuel, especially onto hot parts.
Remove any spilt fuel immediately.
Use the correct fuel grade.
Do not mix fuel with other liquids.
Fill the tank only up to the maximum marking. If there is no Maximum marking, do not fill up the tank
completely.
Lock the fuel cap securely after refueling.
Operation in closed rooms
In closed or partially closed rooms such as tunnels, drifts or deep trenches, ensure sufficient ventilation
and extraction by, for example, providing a powerful exhaust air fan.
Danger of poisoning!
Do not inhale exhaust fumes. They contain toxic carbon monoxide that can lead
to unconsciousness or death.
Caution with hot parts
Do not touch any hot parts such as the engine block or exhaust muffler during operation or directly
afterwards. These parts can become very hot and cause severe burns.
Shutting off the fuel tap
When the machine stops, shut off the fuel tap.
