To do a check of the hand guard (HA110, for gasoline
products only)
The hand guard prevents hands from coming in contact
with the moving blades, for example, if the operator
loses grip on the front handle.
1. Check that the hand guard is fitted correctly.
2. Check that the hand guard is undamaged.
To do a check of the blades
To ensure good cutting results it is important that the
contact pressure between the blades is correct.
1. The contact pressure is adjusted by turning the
screws on the underside of the bar clockwise as far
as they will go.
2. Then turn the screws anticlockwise a 1/4 turn.
3. Lock the screws using the locking nut on the top of
the bar.
4. Check that the screws are loose enough to allow the
washers under the screw heads to slide sideways.
5. When the blades are correctly adjusted the play
between the blades should be 0,2–0,4 mm,
measured at the screws.
6. The edges of the blades are too hard to be filed. Dull
blades should be sharpened using a grinder.
7. Replace the blades if they are bent or damaged.
