ADJUSTING THE HEIGHT OF THE MOWING MECHANISM IN THE DRIVING DIRECTION
(applicable to machines AJ102 AJ102 4X4 AND AG 122)
Check the height of the
front edge
A
of the mowing mechanism above the ground. This
must be
13–15 mm
and the edges on both sides must be the same.
If the height is different, tilt the seat up and, depending on the model of machine, remove
either the battery compartment or the tool compartment. Loosen the lock nut (
2
) and turn
the nut to adjust the height (
1
). After setting the correct height, don’t forget to tighten the
nut (
2
).
6.3.7a
As soon as the front edge is at the correct height, place an appropriate washer of the
corresponding height underneath it.
Check the height of the mowing mechanism’s
rear edge B
. It must be
10-13 mm
higher
than the front edge, i.e.,
23-25 mm
above the ground. If the height is incorrect, adjust it
by loosening the screw (
3
) on the mowing mechanism frame. Then retighten the loosened
nuts and bolts to 55 – 65 Nm.
6.3.7b
HEIGHT OF ADJUSTMENT OF MOWING MECHANISM IN THE DIRECTION OF THE RIDE
(applies to AJ110 machines AJ110)
Control the height above ground of the
front edge A
of the mowing mechanism (measured
on the side of the cover), which must be
35–40 mm
and must be the same on both sides
of the edge.
Control the height of the
rear edge B
of the mowing mechanism. This must be
5-8 mm
higher thanthe front edge.
6.3.7b
BALANCING THE MOWING MECHANISM SIDEWAYS
The mowing mechanism must be properly set
on the sides
(
6.3.7c
). The left and right sides of the
mechanism must be horizontal.
Loosen the bolts on the left and right sides of the adjustment plate (
1
).
6.3.7d
Under the mower mechanism cover (
2
) place inserts of identical height (
3
) (e.g., wood
panels, etc.) and use them to balance the cover such that the left and right sides are equal
distance from the ground. The difference between the left and right sides of the cutting
mechanism should be
no more than 5 mm
.
Then retighten the loosened nuts and bolts to 55 – 65 Nm.
6.3.7e
If you are not sure of the procedure, have a service centre do this for you.
6.3.8 MOWING MECHANISM - INSPECTION AND ADJUSTMENT OF THE V-BELT
With time, stress loosens the mowing mechanism’s drive belt, and it must be tightened. The
belt is tensed by pulleys and springs.
Transfer the spring (
1
) to the second hole in the pulley tensioning lever (
2
).
In the case of machine AJ 110, stretch the stretching spring (
3
) of the belt to
A=45 ± 1 mm
using the stretching tie rod with nut (
4
).
Stretch the spring of the mowing mechanism (
5
) driving belt to
B=135 ± 1 mm
(in
position 7), once again using the stretching tie rod with nut (
6
).
6.3.8
6.3.9 MOWING MECHANISM - ADJUSTING THE BLADES’ TOOTHED DRIVE BELT
(Machines AJ 102, AJ102 4x4, AG 122)
Set the mowing mechanism to the lowest position by setting the adjustment lever to
position
1
.
Loosen the bolt on the plastic cover on the right side in the driving direction and lift the
cover.
