easily.

• It is necessary to adopt the high purity with low composition of the impurity, the moisture

and the tar. Especially apply the liquid gas fuel in which propylene content should not

higher than 5%.

• If the local gas source is not good, be sure to perform the maintenance regularly in order to

eliminate the eyewinker and the tar accumulated in the system. Replace the filter screen

piece and so on, so that the engine will run smoothly. The poorer the quality of the fuel is,

the shorter the maintenance period for the single time is.

• At the cold district or the temperature is below the 0 ℃ , the natural evaporation rate gets

slow, at this time, it is better to increase the propane in the liquid gas, so that the liquid gas

volatilizes.

3) Disposal of the accident and the emergency

a) Fill the odorant to the general liquid gas, therefore the leakage condition can be tested

easily. If smell a peculiar taste:

• Drive the forklift to the place with good ventilation in the open air. Shut down the engine.

Make sure there is any fireworks around.

• Screw and close the hand cutoff valve on the gas bomb.

• Check each pipeline, interface and conversion device progressively and carefully, find out

the leakage part, ask for the qualified or experimental technical pesronnel to perform the

operation.

b ） If the accident happens:

• Park the forklift immediately, shut down the engine..

• Screw and close the hand cutoff valve on the gas bomb.

• Make sure there is no fireworks around, use the fan to exhale the leakage gas if necessary.

• Ask for the qualified or experimental technical pesronnel to check the problem completely

and perform the maintenance.

c ） If the fire occurs: ：

• If possible, rotate and close the hand cutoff valve switch.

• If there is the water source, water the gas bomb to cool it down.

• Inform the fire departure of firefighting.

• If the gas bomb fires, it is necessary to evacuate the personnel nearby emergently.

4 ） Precaution during the operation

• Do not operation the forklift at the place which has the fire source.

• All the electrical wire connection should be fast to avoid the short circuit and other faults.

• Do not use the fuel oil indicator which is on the fuel LPG forklift, prior to the liquidometer
