7 Charger Safety
– Inspect the hedge trimmer for loose parts (nuts, 
screws, etc.) and for cracked, bent, warped or 
damaged cutting blades. Replace damaged cutting 
blades before using the hedge trimmer.
– Always keep the cutting blades sharp.
■ To reduce blade friction and the buildup of dirt, which can 
interfere with the proper functioning of the hedge trimmer:
– STIHL recommends that you spray the cutting 
blades with a resin solvent, such as STIHL Resin 
Remover and Lubricant, before starting work.
