Clean the cylinder ns with compressed air or a brush (MA5).
(1) Cylinder
(2) Intake air cooling vent (back)
IMPORTANT
If waste gets stuck and causes blockage around the intake air cooling vent or between the
cylinder ns, it may cause the engine to overheat, and that in turn may cause mechanical
failure on the part of the hedge trimmer.
Blades
Oil blades each gas tank lling (MA6).
WARNING
Make sure that the blade bolts are well tightened.
The blade assembly is designed to automatically compensate for any
play between the blades.
SHARPENING (MA7)
Always keep the le or sharpener at an angle of 45° to the blade, and
always grind in the direction of the cutting edge.
NOTE
Files cut only in one direction: lift the le from the blade when returning
to start a new pass.
Remove all burr from the edge of the blade with a slip stone.
Remove as little material as possible.
Before retting the sharpened blades, remove lings and then apply
grease.
Do not try to sharpen a damaged blade: change it or take it to an authorized service center.
Reduction gearbox
Rell gear housing every 25 working hours.
Use grease pump. Feed grease until it comes out of the base of
blades (MA8).
