Starting The Engine; Stopping The Engine; Warming Up; Warming Up In Cold Weather - Zetor UTILIX HT Series Operator's Manual

Starting the engine

Before starting the engine, perform pre-operation check as
described in the chapter Safe Operation of Tractor.
(1) Sit into the driver's seat.
(2) Depress the foot brake.
(3) Move the hydraulic lever in the lower position.
(4) Move the gearshift lever to neutral.
(5) Insert the ignition key and turn it to the ON position.
(6) Check that all indicator lights are working.
(7) The operator must turn the key to the ON position. The
glowing circuit is automatically activated. The operator
must wait until the glowing indicator light switches off.
When it switches off, turn the key to the start position and
start the engine.
(8) Check that the engine is running and all warning lights
are off.
Important:
Never turn the key to the start position while the engine is running as this can cause serious damage
to the starter and engine flywheel.
Only engage the starter for a period of not more than 10 seconds.
If Engine does not start, rest the starter for about 20 seconds and try again for a maximum of 10
seconds.
If the engine does not start after repeated attempts, refer to the fault tracing guide.
Important: Especially in cold weather, always allow the tractor to idle for a while to warm up &
build up sufficient oil pressure to ensure normal operating temperature for longer engine life.

Stopping the engine

- After light work let the engine idle for a while and turn the key off.
Important: After long or heavy work allow the engine to idle for 5- 10 minutes and turn the key
off.

Warming up

When starting the engine allow it to warm up to operating temperature by allowing it to idle 5-10 minutes to
ensure full lubrication and operating temperature. Failure to do so can shorten engine life substantially.

Warming up in cold weather

Cold weather will change the viscosity of the oil, resulting in a reduced oil pumping capacity, which can
cause damage to the engine if it is not warmed up correctly. It also causes problems with the hydraulic
system and the synchromesh in the transmission.
Correct times for warming up are:
Temperature
Above 50°F
50°F ~ 32°F
32°F ~ 14°F
14°F ~ -4°F
Below - 4°F

Running-in Period

Make sure to observe the following instructions for use in the first 50 hours of machine operation.
(1) Do not drive at excessive speed and do not overload the tractor.
(2) Only use the tractor's full power if the engine is sufficiently warmed up.
(3) Do not run the engine to maximum speed.
(4) Perform regular maintenance and change oil and fluid after 50 hours of use.
(5) To refill and replace engine oil, see Maintenance.
