4.3 BRAKE ADJUSTMENT
Reduced braking power is corrected by adjusting
the spring on the brake rod, which is reached
through the inspection hatch beneath the seat.
The adjustment is to be made with the parking brake
engaged and consists of altering the length of the
spring
(4)
to the best measurement. The braking
capacity is increased by screwing the nut
(3)
down on
the rod (and thus shortening the length of the spring).
Loosen the nut
(1)
which holds on the bracket
(2)
and
turn the nut
(3)
until the length of the spring
(4)
is:
A
= 47.5 ÷ 49.5 mm
➤
For mechanical drive models
B
= 45 ÷ 47 mm
➤
For hydrostatic drive models:
measured from the inside of the washers.
When the adjustment has been made, tighten the nut
(1)
.
Never go under these amounts to avoid overloading
the brake unit.
When the adjustments have been made, the parking
brake should prevent the machine from moving on a
slope of 30% (16°) with the driver in position.
➤
In mechanical drive models:
If braking is still poor or unsteady even after making
the adjustment, remove the control rod
(5)
from the
lever
(6)
and check that the latter has an idle stroke
of 20 mm (measured on the vertical in correspon-
dence with the pin axis) before braking starts; oth-
erwise the idle stroke can be adjusted using the
screw
(7)
, unless the brake pads or disc are so
worn that they need replacing [see 6.11].
When connecting the rod
(5)
be sure to use the
lower
hole in the lever
(6)
and then check the
length of the spring again
(4).
