5.1. ADJUSTMENT
OF
THE
WORKING
DEPTH
The depth adjusting wheel permits to obtain a homoge-
neous processing depth thanks to its vertical movement.
This adjustment can be made by acting on crank
B
.
To adjust the working depth simply act on the crank as fol-
lows:
•
Loosen the locking spring
A
and free the crank (Fig.5.1).
• Rotate
crank
B
counterclockwise to increase depth and
clockwise to reduce it (Fig.5.2).
•
Hook the locking spring
A
again;
•
Adjust all the elements to the same working depth.

5.2. DEVICE TO MAKE THE ELEMENT
HEAVIER
This device, to be used only wherever the characteristics of
the ground require it (generally “hard” ground), is used to
make the element heavier and increase the impact of the to-
ols on the ground.
The system consists of a spring
M
mounted on the parallelo-
gram (Fig.5.3) , which can be switched in 3 different positions
according to the type of ground, namely on:
K1 - K2
for light ground;
K3 - K4
for medium ground;
K4 - K5
for heavy ground;
