Starting the Engine in Low Temperatures (below 40F):
When starting the tractor in low temperatures (below 40F), use the
engine preheater. Put the fuel throttle lever in the one-quarter throttle
position, turn the key clockwise to H position and leave it on H for
15–20 seconds. Turn the key to the ST position to engage the starter.
Release it immediately after starting and the key will automatically
return to the ON position.
2.5 Running the Engine
1. Once the engine is started, ease up on the throttle immediately. Check the engine oil pressure to ensure that
the indicator on the oil pressure gauge is in the green zone. The oil pressure indicator light should turn off
at this time.
2. Do not attempt to run at full-load immediately. It is necessary to run the engine at medium speed to warm
it up. When coolant temperature is above 60°C (140F), you can then increase the speed and operate the
tractor with a full load.
3. The engine rpm and load should be varied between low and high speed, especially for a new engine. Do not
attempt to run the tractor at high speed using the fuel throttle lever or the accelerator foot pedal.
4. When running the engine, the oil pressure and coolant temperature should be checked regularly. During the
normal operations of the engine, the cooling temperature should be around 85°C (185F) and the engine oil
pressure should be 310 to 345kPa. (45-50 psi).
IMPORTANT ISSUES: In order to avoid damage to the engine, never let the oil pressure gauge
fall into the red zone. If the oil pressure is dangerously low, shut down the engine and troubleshoot the
problem immediately.
