4.1.2Check and add fuel
Check the remained fuel level in the fuel tank and add the recommended fuel as 
necessary.
4.1.3Check and add oil
Check the oil level with oil dipstick. If the remnant oil level is too low, add the 
specified oil to the upper limit level, inspecting the level to avoid spilling.
4.1.4Check and add cooling water
Check the cooling water level in the radiator and sub-tank after the engine is 
cooled down. If the level is too low, add the soft water properly. In daily inspection, 
just add cooling water into the sub-tank. If the cooling water level is lower than the 
limit, then check the water level in the radiator.  
4.1.5Check the agility of governor lever
The governor lever should be operated lightly. If it is hard to manipulate, add oil to 
the governor cable joints and pivots. And if there is a dislocation or excessive 
clearance between the governor and the control level, adjust it to normal state.
4.1.6Check alarm system
Check all the alarm systems to ensure the alarm system would function normally. 
If the alarm system lost its function, it will result in a serious fault. 
4.2Starting
4.2.1Start the engine as shown below:
4.2.1.1 Release all clutches or turn the starting switch to OFF position to cut off 
the driven load.
4.2.1.2 Open the fuel tank switch.
4.2.1.3 Turn on the battery switch.
4.2.1.4 Insert the key into the starting switch.
4.2.1.5 Turn the key to ON position. Check whether all the alarm system are 
normal or not.                                                

4.2.1.6 Set the governor (control lever) at the LOW position.
4.2.1.7 Turn the key to the START position to start the engine. Once the engine 
starts, release the key right away. And the key automatically returns to ON 
position.

Operate the start switch within 15seconds, otherwise 

it will overheat the starter motor.

There should be 15 seconds interval for starting the 

engine again.

Starter motor may only drive the flywheel gear to 

rotate, but flywheel gear cannot drive the starter motor 
to rotate. Otherwise, starter motor will be damaged. So, 
once engine is started, disconnect the start gear from 
the flywheel gear immediately.

4.2.2Start the engine at low ambient temperature
If the engine is hard to start in cold weather (approx. 0? or below), use the glow 
plug for easier start.
Follow steps 4.2.1.1to 4.2.1.6 as above, and then follow the steps as below:
4.2.2.1 Turn the key from OFF to HEAT, and stay there for about 15 seconds until 
the glow plug finish preheating process. 
4.2.2.2 Turn the key to the START position. After the engine starts, release the 
key at once. And the key automatically returns to ON position.
4.2.3 Restart after failure
If the engine fails to start, wait about 30s to reach the normal battery voltage level, 
and then turn the switch key to START. If the engine cannot start after several 
attempts, eliminate the troubles and restart the engine.
4.2.4Check and operation after starting
After the engine starts, run it at the idle speed and check the following items

Alarm lamps and instruments

no display of 6 alarm lamps indicates normal 

state. 

Water leak, gas leak and oil leak from engine.
Color of exhaust gas.
Vibration or noise of engine.

.

Running

4.3.1Run the engine at a low speed without any load for about 5 minutes to 
lubricate all the moving parts of the engine, but without long time idle running.
4.3.2Increase its speed while the engine is applying for loading and check for the 
rotating sate such as color of exhaust gas, vibration and noise of the engine.
4.3.3Adjust the engine speed by operating the governor lever (control lever) of the 
accelerator. And engine speed regulation is realized by adjusting the accelerating 
spring. If the spring increases, as well as fuel supply and engine speed will 
increase. If the spring decreases, the result will be opposite. 
4.3.4Move the governor lever in the accelerator slowly. Avoid accelerating or 
decelerating the engine fast. It benefits the engine life by increasing the load step 
by step. 

High-speed operation or sudden load without preheating process may result in 
engine seizure.
