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.
Important:

Especially in cold weather, always let the tractor idle for a while to warm up and generate
sufficient oil pressure.

This will ensure normal operating temperature and longer engine life.
Warming Up in Cold Weather
Cold weather changes the viscosity of the oil, resulting in a reduction in the performance of the engine oil
pump, which can cause engine damage if not heated properly.
At the same time, there may be problems with the hydraulic system and synchronization in the transmission.
Warming Up Time
Important:

Make sure the parking brake is engaged during warm-up.

Insufficient warm-up may cause problems or shorten the life of the relevant components.
When the engine is warmed up, depress the clutch and move both shift levers into the desired positions.
Depress the brake pedals and release the parking brake.
Increase engine speed and smoothly release clutch for smooth start.
When driving, change gears only with the (main) gear shift lever and always with the clutch pedal fully
depressed.
Storage of the engine in operating conditions for 3 months or longer
If the engine is not operated for a period of three months or longer during storage, internal engine parts may
corrode and lose oil film.
As a result, the engine may seize when restarting after a long downtime.
In order to prevent this, the engine must be periodically started up.
Temperature Time for warming up
Above 50 °F 5~10 min.
50 °F~32 °F 10~20 min.
32 °F~14 °F 20~30 min.
14 °F~-4 °F 30~40 min.
Below -4 °F Over 40 min.
