4.8 Maintenance and repairs
Before beginning cleaning, 
adjustment, repair and 
maintenance operations, park 
the machine on firm, level ground, engage 
the parking brake, stop the engine, allow it 
to cool down and remove the ignition key.
Allow the machine to cool down before 
working on or around the engine, exhaust 
manifold or muffler; this also applies in 
particular to all maintenance operations on 
the mowing deck. Temperatures of 80 °C 
and above can be reached. Danger of 
burns:
Direct contact with engine oil can be 
dangerous. Engine oil must not be spilled.
STIHL recommends leaving the task of 
topping up engine oil or performing engine 
oil changes to a STIHL specialist dealer.
Cleaning:
Following operation, the entire ride-on 
mower and the attachments must be 
cleaned. In particular, all grass residues 
must be removed because the moisture 
these contain leads to damage in the long 
term. 
STIHL does not recommend the use of 
high-pressure cleaners. (Ö 15.2)
Remove the mowing deck for cleaning 
operations. Never clean the mowing deck 
using water under high pressure (e.g. 
garden hose) or by engaging the mowing 
deck in puddles of water.
Never drive close to an edge or a ditch for 
the purpose of cleaning (e.g. the frame of) 
the ride-on mower.
In order to prevent fire hazards, keep the 
engine, cooling ribs, battery compartment, 
area around the fuel tank and exhaust free 
from grass, leaves or escaping oil (or 
grease).
Always clean the grass catcher box.
Maintenance operations:
Only maintenance operations described in 
this instruction manual may be carried out. 
Have all other work performed by a 
specialist dealer.
If you do not have the necessary expertise 
or auxiliary equipment, please always 
contact a specialist dealer.
STIHL recommends that you have 
maintenance operations and repairs 
performed exclusively by a STIHL 
specialist dealer.
STIHL specialist dealers regularly attend 
training courses and are provided with 
technical information. 
Only use tools, accessories or 
attachments approved for this machine by 
STIHL or technically identical parts. 
Otherwise, there may be a risk of 
accidents resulting in personal injury or 
damage to the machine. If you have any 
questions, please consult a specialist 
dealer.
The characteristics of original STIHL tools, 
accessories and spare parts are optimally 
adapted to the machine and the user's 
requirements. Genuine STIHL spare parts 
can be recognised by the STIHL spare 
parts number, by the STIHL lettering and, 
if present, by the STIHL spare parts 
symbol. On smaller parts, only the symbol 
may be present.
The ride-on mower and all attachments 
should be inspected once annually by a 
specialist dealer. (Ö 15.1)
Always keep warning and information 
stickers clean and readable. Damaged or 
missing stickers must be replaced by new, 
original plates from your STIHL specialist 
dealer. If a component is replaced with a 
new component, ensure that the new 
component is provided with the same 
stickers.
For safety reasons, fuel-carrying 
components (fuel line, fuel cock, fuel tank, 
tank cap, connections, etc.) must be 
checked regularly for damage and leaks 
and replaced by a technician if necessary 
(STIHL recommends STIHL specialist 
dealers).
Before starting work on or near electrical 
components, the negative (–) cable must 
be disconnected from the battery.
The machine is equipped with numerous 
safety devices. These devices must not be 
removed or modified (bypassed, etc.) and 
must be checked at regular intervals. 
Operations on the safety devices must 
only be carried out by a technician. STIHL 
recommends STIHL specialist dealers for 
this purpose.
Be aware that moving one cutting tool 
results in the turning of the other cutting 
tools.
Ensure that all nuts, pins and screws, 
especially the blade fastening screws, are 
securely tightened, so that the machine is 
in a safe operating condition.
For safety reasons, worn or damaged 
parts must be replaced immediately.
Check the grass catcher unit (e.g. grass 
catcher box, discharge chute) regularly for 
wear, damage or loss of functionality.
Particular care is required when working 
under the machine, due to the weight of 
the ride-on mower. Consult your specialist
