Operation Instruction
damaging it.
2.
Starting time should not be more than 5s each time and starting interval should not be less than 15s each
time. To maintain the battery charging performance, continuous times of starting engine should not exceed 3
ones. If failure after successively 3 times, please find out the cause and start again.
3.3.2.1 Battery starting
Ambient starting (over -5 ℃): Turn the ignition key clockwise to “ON” to turn on the circuit. Then rotate it
again to “ST” to start engine. After engine is started, please immediately let your hand go, the key will
automatically return back to “ON”. As tractor has safety starting switch, firstly depress down the main clutch
pedal, then rotate the key to start engine.
Pre-heat starting (only limited to tractor type with pre-heat circuit)
Use the pre-heat to start the engine at lower temperature (below -5 ℃), as the cold start is difficult. Place the hand
throttle to full position. Rotate the starting switch clockwise to Preheat for hold it for (15~20) s and then to ST to
start engine. After engine is started, the key will automatically return back. At last place the handle throttle to
small-openness position.
As to the tractor without pre-heat circuit, before starting engine in severely cold winter, fill the radiator with over
90
Drain the oil in the oil sump (it is best to drain it when still hot) into a container with cap to be heated to
(70~90) ℃
. Then refill into oil sump. Never heat the oil sump.
3.3.2.2 Starting engine by towing tractor: when towing tractor, please engage high III-gear or high IV-gear.
To ensure safety, the speed of towed tractor should not be more than 15km/h.
Note:
In the case of tow start the tractor, once the engine operates, depress the main clutch pedal immediately and
reduce throttle opening.
3.3.3 Engine running
After eng
ine starting, please immediately decrease the throttle openness to allow the engine at idle speed. At
this time, check the engine oil pressure and ensure the oil pressure gauge pointer is pointing to green range.
After startup, the engine should not run at full-load immediately. It is correct to let the engine to be heated at
middle speed and with no load. Do not increase to max. speed or put it into full-load work until the coolant
temperature is up to 60 ℃ or more.
Slowly increase or decrease engine speed
and load, especially to justly started engine. Do not run at high
speed by “full throttle”.
During running, always check the oil pressure and coolant temperature. The indicator shall stay in green area
during the operation.
Important: During engine runni
ng, the oil pressure gauge pointer should not point to red range at left side at any
