22. Diagnostics of hydraulic system defects
Watch until brake indicator lamp goes OFF with the ignition •
key turned ON.
Brakes of the machine have been released for towing.
Before you release the brakes, wedge the both drums against any spontaneous movement of the ma-
chine thereafter.
When braking o the gearbox, hydro motors and short-circuiting the hydraulic loop of the travel, it will
not be possible to use operating, emergency or parking brakes! All brakes are now disabled!
Due to the seepages the pressure may drop when towing; check brakes do not heat up due to insuf-
cient braking o.
When towing, please use undamaged towing cable or pull rod of sucient loading capacity 1,5 higher
than the weight of hauled Machine. It is forbidden to use a chain for hauling.
No person may stay on a towed Machine where engine does not work.
It will be necessary to maintain minimal deection from direct angle of hauling. Max deection will be
possible within angle of up to 30°.
It will be required to keep moving continuously when hauling. Do NOT exceed hauling speed of over 2
km/hr. (1.2 mph).
The machine should only be towed for the shortest possible distance – to extricate the machine if it gets
stuck or is blocking trac in case of breakdown. Do not tow the machine for a longer distance than 300
m (0.19 mi).
The hauling machine shall t with its size the Machine broken. It shall have sucient hauling force (per-
formance), weight and brake eect.
When hauling downhill with the help of cable it will be necessary to attach next hauling machine to
the rear part of the Machine broken. In this way it will be possible to avoid uncontrolled motion of the
Machine damaged.
Do NOT start the engine when towing the Machine.
A sunk Roller can be hauled for a short distance if its engine is running and the drive and steering work.
Driver on hauled Roller must steer the Roller in hauling direction.
Unless the engine works, measures have to be taken to avoid any damage to the steering, drive and
brake that are not eective.
When towing is completed, please secure the wheels and drum with scotch blocks (cotters), and put
into initial state.
