Stihl HSA 25 Instruction Manual page 32

English
► After sharpening, wipe away filing or grinding dust with a
dry or slightly dampened cloth and then spray the cutting
blades with a resin solvent, such as STIHL Resin
Remover and Lubricant.
If you make a warranty claim for a component which has not
been serviced or maintained properly, coverage may be
denied.
NOTICE
Operating the machine with dull or damaged cutting blades
may overload the motor. Keeping the cutting blades sharp
helps maintain cutting performance and the expected life of
the product.
