Blades
Hedge trimmer blades are very sharp, touching them may lead
to severe personal injury. Use long hex wrenches and sockets
with extensions when tightening blade bolts and blade lock nuts
to keep hands at a safe distance from sharp blades.
Blades should only be removed and reinstalled by an authorized
servicing dealer, otherwise premature wear or internal damage may
occur.
Accessing Blade Edges
For blade maintenance procedures or inspection, blades can be manually
moved to separate top and bottom blade teeth.
1. Remove plug bolt (A).
2. Insert M4 bolt (B), at least
15mm long (not included)
into bolt hole.
3. Rotate bolt to manually
move blade teeth for access
to cutting edges.
