“Mowing
Tips”.
The cutting gear of your lawn mower was optimally adjusted be-
fore leaving our company. If, after longer use, a clean cut of the
grass is no longer possible or the blade roller contacts the lower
blade, then the lower blade should be adjusted.
1. Remove the plug from the mains socket.
2. Check cylinder
J
and lower blade
K
for notches and remove
these with a grindstone if necessary.
3. Unscrew internal hexagon screws
L
with an internal hexagon
wrench (5 mm) anticlockwise until the cylinder
J
turns freely.
4. Push the feeler gauge supplied (thin strip of metal)
M
on the
left side between one blade
J
on the cylinder and the lower
blade
K
.
5. Tighten left internal hexagon screw
L
with an internal
hexagon wrench (5 mm) until the feeler gauge
M
is held
gently.
6. Continue turning the cylinder until the blade
J
, already
adjusted on the left side, is exactly above the lower blade
K
on the right side.
7. Tighten the right internal hexagon screw
L
with an internal
hexagon wrench (5 mm) until the feeler gauge
M
is held
gently.
8. Rotate cylinder
J
. If a banging noise is produced during this,
open up the internal hexagon screw
L
slightly on the side
affected.
When the cylinder and the lower blade can hardly be heard
touching each other, the cutting mechanism has been adjusted
correctly.
9.
Cutting test:
Place a strip of paper
N
in such a way on the lower blade
K
that it points towards the spindle of the cylinder
J
.
10. Turn cylinder
J
carefully.
If the lower blade is set correctly
K
the paper will be cut off
as if with scissors.
11. Repeat the cutting test on the other blades
J
.
On safety grounds, only original GARDENA spares
A
may be used.
Please contact GARDENA Service if it is necessary to replace
the cutting tool, which will only become blunt after several years
use if well-maintained.
