Preventive daily maintenance.
z
Perform this maintenance daily or after every 8 - 10 hours of operation at the latest.
Safety cab
z
If the protective frame of the safety cab is damaged by corrosion, an accident or otherwise, the safety
cab must be replaced.
Air-conditioning
z
Disassembling, turning or otherwise handling the screw union of the air-conditioning system is not
allowed in any case. Sudden leak of the coolant may occur, causing quick local cooling. Contact or
freezing of components in hands may cause serious damage of some tissues.
z
The air-conditioning system is equipped with quick-couplers that make it possible to separate the cab
from the tractor body if necessary without any coolant leak. Entrust interventions into the air-
conditioning system to a specialized repair shop.
Electric installation
No additional interventions into the electric installation (connection of other electric
appliances) are permissible due to its possible overloading!
z
The values of the electric installation are:
Nominal voltage 12 V =
Grounded minus pole ( - ) pole
z
Using starting trucks or auxiliary power supplies with a different voltage or polarity may cause serious
failures of the tractor.
z
When handling the battery you must pay increased attention and avoid short-circuits. In tractors
equipped with a battery disconnector switch the disconnector off when handling the battery.
z
Zetor tractors must not be operated with a disconnected battery as this may lead to a serious failure of
the tractor.
Work in a chemically aggressive environment
z
If the tractor is operating in a chemically aggressive environment (e.g. working with chemical sprays,
fertilizers, in environments with high concentrations of salt, etc.), it is always necessary to clean the
tractor thoroughly from chemically aggressive substances and neutralize them after the termination of
the work according to the manufacturer's instructions.
