The electrolyte is sulfuric acid. Please don't let the 

electrolyte spatter on your eyes, skin and coat to avoid 
serious hurt. 

If the electrolyte's liquid level is on the  "LOWER 

LEVEL" marks, please don't use the battery again, 
Otherwise, it will cause aging inside the battery, shorten 
the use lifetime of the battery and even the battery will 
explode.

3.1.4.1Checking the electrolyte's liquid level
Please remove the BATTERY cap and 
check the electrolyte's liquid level. The 
electrolyte must keep above the middle of 
the upper and lower level marks. If below 
the middle, please add electrolyte.
3.1.4.2 Checking the electrolyte's proportion
Please refer to the following table of the 
mutual connection among the electrolyte 
temperature, proportion and recharging rate. 
When the remaining bulk is below 75% and 
the electrolyte's proportion is between 1.23 
and 1.24, please charge the battery.

Reference table of electrolyte temperature, proportion and charging rate%

3.1.4.3 The positive terminal must not be connected to the negative terminal 
when checking circuitry Otherwise, it will break the diode on alternator 
3.1.4.4 Open the battery cap to let the gas come out during charging.
3.1.4.5 Stop charging the battery for a moment to cool the battery liquid when it is 
overheated (above 45

),then go on after the battery is cooled down.

3.1.2.1 The specification the Oil
CD Level classified under API
Choosing the correct mucosity oil 
according to surrounding temperature. 

3.1.2.2 the use of the Lubricant Oil

Stock & Using the Oil properly, Avoiding dirt or dust 

falling into the oil. Cleaning the Filling-Jaws area while 
filling the Oil.

In order to avoid impacts of the oil character, Please do 

not use mixed oil with different specification.

3.1.3 Cooling water

The misapplication of cooling water may cause radiator, housing unit and cylinder 

begrimed and then affect the cooling.

More attentions should be taken in cold area because the frozen cooling water 

may damage such parts as radiator, housing unit and cylinder cover.
3.1.3.1 Cooling water
Using soft water (from tap water or rain water), and add durable LLC to avoid rust 
and freezing.
3.1.3.2 LLC
To select good-quality durable LLC can avoid rust, and then the antirust is not 
necessary. The useful-life of cooling water is one year and it should be replaced 
once a year.
3.1.3.3 The ratio of the LLC in the soft water should between 30% and 55%. In 
standard area (-15

above), it should be 30%; and in cold area ( -35

above), 50%.

NOTE

The lowest environment temperature

3.1.3.4 The ratio should be moderate: If the ratio of LLC is too low, it is difficult to 
avoid freezing and rust; on the contrary, if too high, it will also have a harmful effect 
on cooling the engine. Please keep to the instructions about the ratio made by 
manufacturer.
3.1.4 Battery Operation 

Charge the battery in a good ventilated place which is 

far from fire. The battery may produce flammable gas. If 
handle it by mistaken, it will cause explode;

The positive terminal must not be connected to the 

negative terminal when checking circuitry or connecting 
with cable. Otherwise, it will cause spark to serious hurt 
and find hazard.
