Empty the fuel tank (e.g. by running it 
empty) before placing the machine in the 
cleaning position.
Remove accumulated clipping deposits 
using a stick. Clean the underside of the 
mower with water and a brush.
Never use high-pressure cleaners and do 
not clean the machine under running water 
(e.g. using a garden hose).
Do not use aggressive cleaning agents. 
These can damage plastics and metals, 
impairing the safe operation of your STIHL 
machine.
In order to prevent fire hazards, keep the 
area around the air vents, cooling ribs and 
the area of the exhaust free from 
e.g. grass, straw, moss, leaves or 
escaping grease.
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.
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).
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.
Only perform work on the cutting unit when 
wearing protective gloves ( 5.4) and 
exercising extreme care.
Ensure that all nuts, pins and screws (in 
particular the blade fastening screw) are 
securely tightened so that the machine is 
in a safe operating condition.
Replace damaged exhaust silencers and 
guard plates.
Check the complete machine and the 
grass catcher box for wear or damage on 
a regular basis, particularly before 
extended periods when the machine is not 
in use (e.g. over winter). For safety 
reasons, worn or damaged parts must be 
replaced immediately to ensure that the 
machine is always in a safe operating 
condition.
Never alter the basic setting of the engine 
or run at excessive engine speeds.
Components or guards that are removed 
for maintenance operations must be 
properly reinstalled immediately.
5.9 Storage for prolonged periods 
without operation
Allow the engine to cool before storing the 
machine in an enclosed space.
Ensure that the machine is protected from 
unauthorised use (e.g. by children).
Store the machine with empty fuel tank 
and the fuel reserve in a lockable and well-
ventilated room.
Never store the machine with petrol in the 
tank inside a building. The resulting petrol 
fumes could come into contact with naked 
flames or sparks and could be ignited.
If the tank has to be emptied (e.g. to store 
the machine before the winter break), this 
should only be done out of doors (e.g. by 
running the tank empty).
Thoroughly clean the machine before 
storage (e.g. winter break).
Store the machine on a suitable surface 
and only standing on its wheels – secure it 
against rolling away.
Only store the machine with the spark plug 
socket disconnected.
RM 650 VE: Before storing the machine, 
remove the battery and store it separately 
from the machine as well as protected 
from unauthorised use (e.g. by children).
Store the machine in good operational 
condition.
Allow the machine to cool down 
completely before covering it.
