every bearing adequately lubricated and oil pressure stable. Gradually accelerate and load the engine after oil
pressure is stable.
xCheck the instruments for operational conditions in engine idle running.
Caution: Do not accelerate and load the engine immediately after it is started up.
Caution: Do not idle the engine for a long period of time or it can cause problems to the engine. When an
engine idles, the temperature in combustion chamber is low and combustion is not complete. It can cause
carbon deposit in cylinder that results in blocking of orifice of fuel injector, as well as the seizures of piston
rings and valve, thus leading to engine performance deterioration.
Caution: If the engine is start by a jumper cable, parallel connection of the cable should be adopted by
connecting the positive pole to the positive terminal and the negative pole to the negative terminal. If the
engine is start by external power supply, the circuit breaker should be set to the position OFF. Take out the
key to prevent accidental activation before connection of jumper cable.
3.4.2 Cold starting
The engine has the ability to start successfully without any pre-warming aid if the temperature is above -15ć. The
engine is equipped with an intake air heating device for fast and smooth start, as well as for keeping speed stable and
improving the smoke after starting up.
There are two types of intake air heating device: electric heating and flame heating.
1) Electric heating device consists of electric heater, electronic controller, temperature sensor and indicator light. Its
work is governed by the electronic controller.
2) Flame heating device consists of flame heating plug, solenoid valve, fuel inlet pipe, electronic controller,
temperature sensor and indicator light. Its work is governed by the electronic controller.
The electronic controller governs intake air heating action according to ambient temperature. The heating is divided
into two stages: heating intake air before engine start (pre-heating) and heating intake air after engine start
(after-heating). Generally, it is not allowed to start engine during the first stage of heating (pre-heating). Once the
engine is started, the pre-heating will automatically stop. Start the engine after the pre-heating is over.
xInsert the electric key and turn the switch from the position OFF to the position ON to electrify the electronic
controller. Pre-heating intake air starts and the indicator light flashes on. Intake air heating ends and the indicator light
flickers. The engine is ready to start.
xTurn the switch from the position ON to the position START to start the engine after the indicator light goes out. The
switch turns back to the position ON automatically after the engine has started up.
xAfter-heating begins and its duration is governed by the electronic controller. The indicator light does not flash in the
process.
Refer to Normal Starting Procedure for other engine starting instructions.
Note: If startup does not happen or the engine has not been started up within 30 seconds after the indicator light
starts flickering, the electronic controller will automatically disconnect the circuits of glow plug, solenoid and indicator
light, entering delay protection. If another startup is initiated, turn the electric key back to the position OFF, and wait for
5 seconds before repeating the above process.
