4. ENGINE USAGE
The first 20hrs are the break-in period of the engine, the operator must obey to following items:
• Warm up the engine 5 minutes after the initial starting.
Run the engine at low speed and zero load before the engine becomes warm. Do not run the engine
at high speed and zero load.
• Do not run the engine with overload.
Run the engine at 3000r/m with 50% load in break –period.
• Replace the engine oil on time.
Replace the engine oil while the engine is warm after
20-hours-running it, drain the old oil
completely. (Please see 8.1 Replacing the Engine oil)
4-1 Selection and usage of the fuel and oil
1. Selection and usage of the fuel and oil. Please use light
diesel most applicable for the performance of the engine.
2. Diesel usage:
• If diesel is mixed with water abnormal running will result. Seal the diesel in clean
drums and store the drums in a dry place away from rain and dust.
• If diesel has been stored for several hours,water and dirt deposits at the bottom of the drum.
You can pump the upper portion of the diesel for usage.
3. Refueling the diesel

4-2 Selection and Usage of engine oil
1. Selection of engine oil
It is very important to select the appropriate engine oil, if you use the improper diesel the piston
rings will adhere together. The piston will burn out, and the cylinder head gasket will wear out
quickly as well as bearings and other moving parts. The engine life will be shortened.
We recomend CC/CD oil classified by API for all four seasons.
The viscosity of the engine oil is depended on the ambient temperature.
Ambient Temperature
SAE 15W-40 Semi Synthetic Oil
2. Check and Refill the Engine Oil

4-3 Replace the air cleaner
1. Screw off the wing nut and remove the air cleaner cover. If the output
power of the engine is not sufficient, the exhaust color will be abnormal,
then it is necessary to replace the element.
2 Re-assemble the air cleaner and screw on the wing nut after replacement.
