Check & Changing the Oil in the Gearbox
IMPORTANT: The used oil is a pollutant and must be
m
disposed of correctly. Pour it into a suitable container
b
and take it to the special oil collection points.
•
Check the oil in the gearbox: Check the level of the lubricant
through the plug “1”, the oil must reach the lower edge of the
hole of level plug.
(Fig 7.2)
•
Changing the oil in the Gearbox: Change the first oil fill after
the first 50 hours service. Following this, the oil should be
changed after every 250 hours service. Consult below for the
recommended type of oil.
Checking the Belt Tension
Work should only be carried out on the transmission belts when the tractor has been turned off, the ignition key is not
in the ignition, the parking break is in position and the drive has been disconnected. When possible, such operations
should only be carried out after the shredder
has been disconnected from the tractor.
Dismount the casings “3”.
(Fig 7.3)
•
The belts are fitted correctly if, when pressing
down, with one hand, halfway between the
multiplier pulley and the rotary shaft, the belts
yield by approximately 12mm (1/2 inch).
•
To tighten the belts, loosen the nut “1” and turn
the screw “2” until the belt is as tight as required.
•
When the belt has been tightened as required,
use the nut to lock it in place.
IMPORTANT: Make sure the belts are intact, that they
are not cracked and do not have ragged edges. If this is
not the case, replace them with new belts.
Check & Replacing Blades
IMPORTANT: It is advisable to replace all the blades at the same time to prevent the machine vibrating.
When mounting the new blades, make sure the cutting edges are positioned in the direction the rotor rotates
in.
•
Place the machine at a comfortable height and
lock it in position with sufficient support to
guarantee the operator's safety. Prevent the
blade rotating by locking
•
the shaft with a key (the shaft is designed for this
with two flat areas immediately above the blade)
•
Using the key, unscrew the nut “1” and remove
the blade.
(Fig. 7.4)
•
Check the state of wear of the pin and the nut
and, if necessary, replace them.
•
Mount the new blade, screw in the nut "1 " fully
and with force, keeping the shaft locked at the
same time as described above.
