49 aRequired distance between depth 
gauge and cutting edge
When cutting softwood outside of the 
frost season, the distance can be 
increased by up to 0.2 mm (0.008").
Lowering the depth gauges
The depth gauge setting is lowered 
when the cutter is sharpened.
NCheck the depth gauge setting after 
each sharpening
NLay the appropriate file gauge (1) 
for the chain pitch on the saw chain 
and press it against the cutter to be 
checked – if the depth gauge 
protrudes past the file gauge, the 
depth gauge must be reworkedSaw chains with humped drive link (2) – 
upper part of the humped drive link (2) 
(with service mark) is lowered at the 
same time as the depth gauge of the 
cutter.
WARNING
The rest of the humped drive link must 
not be filed; otherwise, this could 
increase the tendency of the chain saw 
to kick back.
NR e w o r k  t h e  d e p t h  g a u g e  s o  t h a t  i t  i s  
flush with the file gauge
NAfterwards, dress the leading edge 
of the depth gauge parallel to the 
service mark (see arrow) – when 
doing this, be careful not to further 
lower the highest point of the depth 
gauge
WARNING
Depth gauges that are too low increase 
the kickback tendency of the chain saw.
NLay the file gauge on the saw chain 
– the highest point of the depth 
gauge must be flush with the file 
gauge
NAfter sharpening, clean the saw 
chain thoroughly, removing any 
filings or grinding dust – lubricate 
the saw chain thoroughly
NIn the event of extended periods of 
disuse, store saw chains in cleaned 
and oiled condition Chain pitch Depth gauge
