Bevel gear

The bevel gear is filled with the right quantity of grease at the
factory. However, before using the machine you should check
that the bevel gear is filled three-quarters full with grease. Use
HUSQVARNA special grease.
The grease in the bevel gear does not normally need to be
changed except if repairs are carried out.
Lubricating the flexible drive shaft
Inside the hollow drive shaft of the edger is a flexible drive
shaft. This flexible drive shaft should be regularly lubricated
every 25 hours in operation. Loosen the two screws on the
bevel gear and remove it. The flexible drive shaft is easily
removed from the hollow shaft by taking a firm grip on the shaft
end. Lubricate the entire length of the flexible drive shaft and
reinsert it in the hollow drive shaft. Turn the shaft while
inserting it so that it correctly engages in the clutch. Refit the
bevel gear on the hollow drive shaft and tighten the two screws.

Adjusting the edger's cutting depth

The cutting depth must be adjusted before starting work.
Loosen the locking knob (A) and rotate the guard by
moving the locking knob forwards or backwards. If the
locking knob is moved forwards (away from the machine)
the cutting depth is increased. If the locking handle is
moved backwards (towards the machine) the cutting
depth is reduced.
Set the desired cutting depth.
Lock the locking knob.
