Once you have identified the pressure relief valve you need to
bypass, proceed as follows:
-
loosen check nut "2" (with a 13 mm wrench) which locks in
place the dowel of the pressure relief valve you need to bypass
(depending on the direction in which you need to tow your
machine).
- while holding the check nut steady, screw dowel "1" clockwise
(with a 4 mm Allen wrench) until the force required for screwing
increases significantly (contact between the dowel end and the
valve slider); once this condition is met, keep on screwing
clockwise by another 1.5 turns (bypass opening is actuated).
- tighten check nut "2" by rotating it clockwise with a torque of 22
Nm (Fig. 3)
CAUTION! While towing your machine, always keep
speed below 2 kph and move your machine just enough to
leave the danger area. In any case, never tow your machine
for longer than 100 metres.
Towing your machine either at a higher speed or for a longer
distance may overheat the hydrostatic motor, with a
consequent damage to pistons.
While towing your machine, the components described in this
paragraph may overheat. Always wear protective clothing!
When you finish towing your machine, disable the bypass function
by carrying out the operations described above in reversed order:
-
loosen check nut "2" (with a 13 mm wrench)
- unscrew dowel "1" completely (with a 4 mm Allen wrench), by rotating it counter-clockwise up to the end of its thread
- tighten check nut "2" by rotating it clockwise with a torque of 22 Nm
NOTE! When you restart the engine after towing your machine, first drain the hydrostatic transmission system
as described in paragraph "EVERY 1500 HOURS - HYDROSTATIC TRANSMISSION OIL", chapter "ROUTINE
MAINTENANCE".
• HOW TO ANCHOR YOUR MACHINE
Use the anchoring points shown below to anchor your machine (e.g. to lock it in
place on a trailer for transport):
C) front anchoring points
D) rear anchoring points
PREPARING YOUR MACHINE FOR BEING ANCHORED
- install proper shackles in each of the indicated points
- tie either ropes or chains to the shackles, and check that they don't come into
contact with machine surfaces
• LIFTING THE MACHINE
-
Disassemble the vehicle attachments
- Assemble suitable clevis in each of the shown points
- Lower and completely retrieve the vehicle boom
- Clamp the ropes to the previously assembled clevis.
The vehicle total weight is written on the identification label outside the cab. Keep
in mind that each clevis and its rope must have a min. lift capacity more than 2/3
of the vehicle total weight. The attachments must be lifted separately from the
vehicle and following the instructions of the pertaining chapter in this handbook
or in the enclosed booklets.
WARNING ! Check that ropes, clevis and lifting devices are in good
condition and that their lift capacity is sufficient for the weight to be handled.
