: File the top of the depth gauge 
parallel to the stamped service 
marking (see arrow) – but do not 
lower the highest point of the depth 
gauge in this process.
The kickback tendency of the 
chainsaw is increased if the depth 
gauges are too low.
: Place filing gauge on the chain – 
highest point of depth gauge must 
be level with the filing gauge.
PM 1, RM2:
Rear hump of tie strap (with service 
marking) is lowered along with the depth 
gauge.
RSC3, RMC3, PMC3:
The upper part of the humped drive link 
(with service marking) is lowered along 
with the depth gauge.
The other parts of the triple-humped 
tie strap and humped drive link must 
not be filed since this may increase 
the kickback tendency of the 
chainsaw.
: After sharpening, clean the chain 
thoroughly, remove filings or 
grinding dust – lubricate the chain 
thoroughly.
: Before long out-of-service period, 
clean the chain and store it in a 
well-oiled condition.
