4.7 Working with your machine
Never work in the vicinity of 
other persons, particularly 
children, or animals. Ensure 
that the grass is never 
discharged in the direction of other 
persons.
Do not operate the machine in the rain or 
during thunder storms, particularly when 
there is  a risk of lightning strike.
Exhaust gases:
The machine generates 
poisonous exhaust gases when 
the engine is running. The 
gases contain poisonous 
carbon monoxide, a colourless and 
odourless gas, as well as other pollutants. 
The engine must never be operated in 
closed or poorly ventilated spaces.
Starting:
The machine must only be started from the 
driver's seat.
Start the machine on level ground, not on 
a slope.
The engine may only be started in a well 
ventilated working area, sufficient 
ventilation must be ensured, particularly in 
garages.
Before starting the engine, disengage the 
cutting tool, attachments and drive and 
press down the brake pedal fully.
When starting, it must be ensured that 
there is sufficient clearance between the 
feet and the cutting tool.
Never start the engine by short-circuiting 
the starter terminal. If the normal starter 
circuit is bypassed, the ride-on mower may 
suddenly be set in motion.
Never start the engine if the smell of petrol 
can be detected – Explosive hazard!
Working:
Only work during the day or with good 
artificial light.
When driving off the lawn or when not 
mowing, the mowing blades must be 
disengaged and the mowing deck must be 
set to the highest cutting position.
Objects hidden in the turf (lawn sprinkler 
systems, posts, water valves, foundations, 
electrical wires, etc.) must be avoided. 
Never run over any such foreign objects.
Always hold the steering wheel firmly with 
both hands when driving.
Particular care must be taken when driving 
on lawns and other uneven surfaces, as 
the steering wheel can be made to turn 
due to holes, mounds, impacts, etc.
Risk of injury to hands and fingers!
If, during operation, a defect in the tank, 
tank cap or in the fuel-carrying 
components (fuel lines) is detected, the 
engine must be stopped immediately. A 
specialist dealer must then be contacted. 
STIHL recommends STIHL specialist 
dealers.
Beware of depressions (holes) in the 
terrain and other invisible points of danger. 
Obstacles can be easily overlooked in long 
grass.
Danger to life through poisoning!
In the case of nausea, headache, 
impaired vision (e.g. decreasing 
field of view) hearing disorder, 
dizziness, decreasing power of 
concentration, stop working 
immediately. These symptoms may 
be caused by excessively high 
exhaust gas concentrations.
Warning – Risk of injury!
Observe the working 
area of the mowing 
blade. Never put hands 
or feet on or underneath 
rotating parts. Never touch the 
rotating mowing blade. Always 
keep away from the discharge 
opening. An adequate safety 
distance must always be 
maintained.
