17 Taking Care of the Guide
Bar
1
► 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 sprocket 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
Chain type Chain pitch
Picco 1/4" P
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.

18 Storing the Machine

For periods of 3 months or longer
► Disconnect the plug from the wall outlet.
► 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.
► Store the machine in a dry, high or locked
location – out of the reach of children and
other unauthorized persons.
19 Checking and Replacing

17 Taking Care of the Guide Bar

19.1 Replace the chain sprocket
– 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 life of the chain. You can
use a gauge (special accessory) 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.
The chain sprocket is driven via a friction clutch.
Have the chain sprocket replaced by an author‐
ized dealer.
STIHL recommends that maintenance and repair
work be carried out only by authorised STIHL
dealers.
20 Maintaining and Sharpe‐
ning the Saw Chain
20.1 Cutting Effortlessly with a Cor‐
rectly Sharpened Chain
A properly sharpened chain slices through wood
effortlessly and requires very little feed pressure.
Working with a dull or damaged chain requires
more physical effort, exposes the user to higher
