of rotation of the power takeoff and cardan shaft!
Disengage at all times the power takeoff when beginning driving on a step slope as
well as in cases where its operation is unnecessary!
After disengaging the power takeoff, the hazard due to the inertial mass remains for
some time. Do not approach the connected machine during this time! Performing any works
is only allowed after complete stop! Stop obligatorily the engine and remove the ignition key!
Cleaning, lubricating or adjusting the aggregate driven from the PTO or cardan shaft
shall be only performed provided that the power takeoff is disengaged, the engine is
stopped and the ignition key is removed!
The disconnected cardan shaft shall be secured on the respective bracket!
After removing the cardan shaft, fit the protective cover to the end of the power take-
off!
Inspect visually the cardan shaft, power takeoff and power intake shaft. Eliminate
immediately the faults revealed!
10.7. Rules concerning the pressurized instruments and mechanisms of the machines
and tractor
Caution! Do not forget about the presence of high pressure in the hydraulic and
pneumatic systems of the tractor and machines aggregated!
When connecting the hydraulic cylinders and hydraulic motor from the complete set
of the machine, check the correctness of connection of the hydraulic hoses!
Prior to beginning connecting the hydraulic hoses to the hydraulic system of the trac-
tor, make sure that the hydraulic circuits of the tractor and aggregate are depressurized!
When performing the hydraulic connection between the tractor and the machine, it is
necessary to mark beforehand the components to be connected in order to avoid errors in
the control of the units of the hydraulic system of the aggregated machine! Erroneous con-
nection of the reverse function (for example, lifting or lowering) can cause an accident!
When connecting the hydraulic hoses of the machine to the tractor’s hydraulic system,
make sure that the system is depressurized; observe the correctness of the connections be-
tween the hydraulic system of the tractor and the hydraulic system of the aggregate in accord-
ance with marking the hoses a n d connecting diagram. The connecting diagram shall be given
in the Operation Manual for the machine.
Check regularly the condition of the hydraulic hoses. Should any damages or ageing
signs be revealed, the hoses shall be replaced without delay! The new hoses intended for
substituting the old ones shall comply completely with the manufacturer’s requirements!
To avoid injury when determining the leakage places, use appropriate aids! A liquid
(hydraulic oil) flowing out under pressure can penetrate under skin and cause heavy injuries!
In case of injury, call immediately for medical aid! Hazard of blood poisoning!
Prior to beginning the work with the use of the hydraulic system of the tractor, lower
the machine, depressurize the hydraulic system, stop the engine and remove the ignition
key!
Any works with the hydraulic and pneumatic connections of the hydraulic accumula-
tors and receivers of the machines shall be performed with the pressure released!
Improper installation and operation of the hydraulic accumulators with violation of the
labour protection requirements can become a cause of heavy accidents.
