5. Construction features
The L LI IP PC CO OP Pa at th hw wa ay yG Gr ra ad de er r, when connected to a (small) tractor, is
capable of loosening, levelling and ramming the area to be treated in
a single operation.
As shown in Fig. 1, the L LI IP PC CO OP Pa at th hw wa ay yG Gr ra ad de er ris equipped at the
front with a roller, which serves for the precise depth adjustment of
the unit. This front roller allows the levelness or the desired
transverse slope to be adjusted precisely.
The rotating gear bar loosens the entire area of the uneven surface.
Special tools allow the machine to be used on hard ground. The
working depth of the gear bar is adjusted by the rear roller. The small
spindle pitch of the adjusting spindle allows the working depth to be
adjusted to the nearest millimeter.
A levelling plate, which levels the already loosened ground, is
arranged behind the gear bar. The round shape of this levelling plate
simultaneously serves for pressing the loosened soil.
Each group can be adjusted separately via adjusting spindles.

8. Connection of the machine to the tractor
•Before starting the machine and the tractor, check road and
operating safety!
•Persons must never be allowed to stand between the tractor and
the attachment unit without having secured the vehicle against
rolling away by means of the locking brake and / or wheel
chocks!
•Never stay in the rotating and pivoting area of the unit!
•Before attaching and removing the Pathway Grader to the three-
point suspension, place the operating device in the position in
which unintentional lifting and lowering is excluded!
•When transporting the unit on roads, sufficient lateral arresting of
the tractor three-point suspension has to be ensured, in order to
avoid lateral swing-out of the machine!
•The compression link should be adjusted such that the machine
runs freely on the front and rear rollers.

9. Connecting the universal joint shaft
•Only use universal joint shafts in perfect condition and with
overload protection!
•When the unit has been coupled to the tractor, check the exact
length of the universal joint shaft.
•Very important:
Highest possible overlapping has to be aimed at. During
operation, the maximum extension of the joint shaft should be
half the sliding profile overlapping (Fig. 2). When connecting to
different tractors, the length has to be checked again!
•Press sliding pin and push the joint shaft
onto the power takeoff shaft until the
sliding pin engages! (Fig. 3)
•This tractor symbol indicates the tractor
side of the joint shaft. Always attach the
overload protection on machine side!
•Attach the holding chain of the joint
shaft in order to avoid a rotation of the
joint shaft protection.

18 - 26 04.11.2004 / 01
•Attach the holding chain so that a sufficient pivoting area of the
universal joint shaft is guaranteed in all operating positions.
Never use the holding chain to suspend the universal joint shaft!
•For your own safety, replace the safety devices if they are
damaged or worn. When the machine is not in use, the universal
joint shaft can be hung in the bracket provided for protection!
•Make sure that when you mount the universal joint shaft on the
machine, the unit protective cover overlaps the joint shaft
protection in all operating positions!
•Lubricate the universal joint shaft before start-up and every 8
operating hours with proprietary grease and check the smooth
running of the sliding profiles. In winter, the protective tubes have
to be greased in order to avoid freezing (see lubrication plan Fig.
4).
Attention!
Only use joint shaft types prescribed
by the manufacturer!

10. Adjustment of working depth/levelling
The working depth of the individual components is regulated by
rotating the particular roller spindles (see Fig. 6). The scales on the
spindles allow an exact adjustment. It is possible to vary the working
depth from 0 to 5 cm. It is important for the machine to rest on both
rollers while working.
Levelling
The levelling is done by means of the levelling plate, which,
depending on the working depth chosen, can be adjusted by hand on
the spindle. For proper levelling, make sure that there is always
some terrain in front of the blade while working. If necessary,
readjust.

11. Maintenance
Steps to be carried out in order to maintain the machine in good
working condition:
•Check the correct connection of the universal joint shaft and the
safety devices.
•Grease the roller bearings (Fig. 8).
•Check the level of liquid grease in
the gearbox via the corresponding
plug (Fig. 9). This operation must
be carried out when the machine
has already been running for a few
minutes and the grease has
warmed up and become distributed
evenly. With the machine switched
off, check the grease level using a
dipstick (the grease level should be
2 cm above the cogwheels). If
necessary, top up liquid gear
grease (based on sodium
bicarbonate - type GP 00).
•For the angular gear, the oil level is
read on the check screw. (Fig. 10)
Oil level up to check screw level.
(In the angular gear, use gear oil
GX 85-90A) The first oil change
should be done after 30-50
operating hours, and then every
200 operating hours, but at least
once a year.
