Starting The Engine While Using Coolant Heater; Immediately After Start; Engine Heating - Zetor Proxima CL 80 Operator's Manual

Starting the engine while using coolant heater

With low temperatures of the surroundings, engine starting eases heating coolant. Leadin electrical
installation and its protection against dangerous contact must be done pursuant to valid regulations
1. First plug the plug to the heater.
2. Then connect heater to electrical network of the voltage of 230 V.
With regard for the lower engine wear with low temperature, the use of heater is recommended by
manufacturer. The duration of heating is dependent on the surrounding temperature (1 - 2 hours before the
expected start).
After completing the heating, disconnect the device first from electrical network and only then
disconnect the plug from the heater! Danger of injury due to electricity!
It is necessary to ensure tractor operator's instruction and regular revision of coolant heater
including feeding cable pursuant to valid legislation of the state where the tractor is operated at least
prior to each winter period.

Immediately after start

After starting, set revolutions to 800 - 1,000 rpm and let engine run without load for a period of
app. 2 minutes.
Check greasing, charging and other functions ensuring proper engine operation (controls must go out) in this
time. The time of engine operation without load must be observed, in particular in winter period.

Engine heating

Do further heating of the engine when driving. Heating engine by lengthy idle run or abrupt
revolutions increase is harmful to the engine. If the temperature of coolant has not reached 45°C, do
not overcome engine revolutions over 2,000 rpm.
