21.2 Cleaning the Cutting Blades
WARNING
To reduce the risk of personal injury from unintended 
activation, remove the battery before carrying out any 
cleaning work, @ 8.1. Users of this hedge trimmer should 
carry out only the cleaning described in this manual. To help 
prevent injuries, always wear heavy-duty work gloves when 
handling the hedge trimmer or its cutting blades, @ 6.3.
To clean the cutting blades:
► Spray both sides of the cutting blades with a resin solvent, 
such as STIHL Resin Remover and Lubricant.
► Insert the battery and switch on the hedge trimmer for a 
few seconds to evenly distribute the resin solvent 
throughout the cutting blades.
► Do not use a pressure washer to clean the cutting blades 
or spray them with water or other liquids.
22.1 Inspecting and Maintaining the Hedge Trimmer
WARNING
To reduce the risk of personal injury from unintended 
activation, remove the battery before inspecting the hedge 
trimmer or carrying out any maintenance, @ 8.1. Carry out 
only the maintenance operations described in this manual. 
There are no user-authorized repairs. STIHL recommends 
that repair work be performed by authorized STIHL servicing 
dealers.
To properly maintain the hedge trimmer:
► Sharpen the cutting blades.
► Have the gearbox lubricated every 50 hours of operation 
by an authorized STIHL servicing dealer.
► Have worn or damaged cutting blades replaced by an 
authorized STIHL servicing dealer.
► Have worn, missing or damaged safety labels replaced by 
an authorized STIHL servicing dealer.
If you make a warranty claim for a component that has not 
been serviced or maintained properly, coverage may be 
denied.
22.2 Inspecting and Maintaining the Cutting Blades
WARNING
To reduce the risk of personal injury from unintended 
activation, remove the battery before inspecting the cutting 
blades or carrying out any maintenance, @ 8.1. To help 
prevent injuries, always wear heavy-duty work gloves when 
handling the hedge trimmer or its cutting blades, @ 6.3. 
STIHL recommends having the cutting blades sharpened by 
an authorized STIHL servicing dealer.
Although it is best to have the cutting blades sharpened by 
a dealer on a workshop sharpener, it is possible to use a flat 
crosscut sharpening file.
Sharpen the cutting blades when cutting performance 
begins to deteriorate, i.e., blades frequently snag on 
branches or fail to cut material cleanly.
To sharpen the cutting blades with a file:
► Sharpen each cutting edge of the upper cutting blade with 
a sharpening file. Always file toward the cutting edge with 
a forward motion matching the sharpening angle, @ 24.3. 
Sharpen on the forward stroke. Lift off the blade on the 
backstroke.
