● Remove the mowing deck. (Ö 14.1)
Turn over the mowing deck (1) and set 
down with the blades facing upwards on 
wooden supports (2) approx. 20 cm high 
and sufficiently long.
● Carefully clean the mowing deck and 
mowing blades. (Ö 15.2)
The mowing blades must be at least 
2.5 mm thick and at least 56 mm wide at 
their narrowest point.
Check the blade thickness of the two 
mowing blades using a slide calliper (1) at 
several points. Check the blade width at 
the point shown, again using a slide 
calliper (1).
Replace the mowing blades if any of the 
measured points no longer meet the 
specified values.
Checking the installation position of 
the mowing blades (RT 5112 Z, 
RT 6112 C, RT 6112 ZL, RT 6127 ZL):
● Set down the mowing deck on two 
suitable wooden supports if necessary.
STIHL recommends removing the 
mowing deck if the wear limits need 
to be checked.
If a suitable lifting platform is 
available, the mowing blade wear 
limits can also be checked with the 
mowing deck installed.
Risk of injury!
The mowing blades must be 
installed offset at an angle of 
approx. 90° to each other to 
prevent them touching during 
mowing.
The mowing deck must not be 
engaged if the angle of the blades 
relative to each other is not as 
specified.
If necessary, consult a specialist 
dealer. STIHL recommends STIHL 
specialist dealers.
STIHL recommends removing the
