► Turn the bar over – every time you sharpen
the chain and every time you replace the chain
– this helps avoid one-sided wear, especially
at the nose and underside of the bar
► Regularly clean the oil inlet hole (1), the oil‐
way (2) and the bar groove (3)
► Measure the groove depth – with the scale on
the filing gauge (special accessory) – in the
area used most for cutting

If groove depth is less than specified:
► Replace the guide bar
The drive link tangs will otherwise scrape along
the bottom of the groove – the cutters and tie
straps will not ride on the bar rails.
19 Storing the Machine
For periods of 30 days or longer
► Remove the saw chain and guide bar, clean
them and spray with corrosion inhibiting oil.
► If you use a biological chain and bar lubricant,
e.g. STIHL BioPlus, completely fill the chain oil
tank.
► If the KombiTool is removed from the Kom‐
biEngine and stored separately: Fit the protec‐
tive cap on the drive tube to avoid dirt getting
into the coupling.
► Store the machine in a dry, high or locked
location – out of the reach of children and
other unauthorized persons.
20 Checking and Replacing
the Chain Sprocket
► Remove chain sprocket cover, saw chain and
guide bar
20.1
Replace the chain sprocket
a
000BA054 KN
–
replace after using two saw chains or sooner
–
if the wear marks (a) on the sprocket are
deeper than approx. 0.5 mm (0.02 in) since
this would reduce the service life of the saw
chain. You can use a gauge (special acces‐
sory) to check the depth of the wear marks
Using two saw chains in alternation helps pre‐
serve the chain sprocket.
STIHL recommends the use of original STIHL
chain sprockets.
