ds. Disassemble the meter and clean them.
2. The rollers are worn. Replace them.
3. The bearings are worn. Replace them
Q: The pump blocked
A: 1. The vanes cannot work freely. Replace them. (Only for vane pump)
2. There are foreign matters in the pump components. Turn off the pump immediately and remove the matters.
3. Pumping elements stick to each other because of heat generated by dry running (It is forbidden to run the pump for a long time without fuel). Stop the pump immediately, after cooling down, reassemble the pump. If damaged, replace it.
4. It is not necessary to replace the complete set of pump if it is struck, only the externalgear and the cover should be replaced with new ones. Please do it according to the following procedure, refer to Figure 11(c):
a. Keep the strainer installed to the oilinlet clean.
b. Screw out the internalgear & the driving shaft assembly (Item 1). Clean the fitting surface and oilpassage.
c. Apply lubricating oilto the driving shaft, and then push internalgear & driving shaft into the pump body. Please do this carefully to avoid damaging the oilseal. The driving shaft should work freely after reassembling.
d. Put O ring (Item 3)into the pump body and make it rest on the hub of pump body.
e. Coat the shaft with lubricating oil, assembly the externalgear (Item 2) around the shaft of the cover (Item 4), and then push them into the body.
f. Please tighten the bolts with turning the belt pulley wheelby hand at the same time.
g. Check if the belt wheelturn freely.
Please turn on the pump with oildelivering not less than 5 minutes. Check if the pump can work normally.

Q: When the pump powered, the counter advances before delivery starts.
A: 1. The hose has flexibility. When pump is powered, oilgoes into the hose and cause the counter to work. In this case, the counter register the same amount each time.
2. The bottom valve or pipe leaks. The fuelleveldrops in the intervalbetween two deliveries. At the beginning of the next delivery, some gas get into the flow meter. In this case, the longer the interval, the more the counter registers, and when the nozzle is opened, gas comes out of the spout.
3. The pipeline waves, the bottom valve or pipe leaks and air is sucked in. Repair the pipeline.
When lifting the nozzle, motor buzzes without movement, or run abnormally
Generally, this is caused by the lack of one phase. Power off the pump immediately to avoid burning out, and check dispenser power supply. If the power supply is good, check the dispenser.
Q: Single phase motor does not turn
A: It is possible that the voltage is excessive low, or the diameter of the cable is too thin. The cross sectionalarea of the cable should be not less than 2.5mm2. The motor may be damaged when the above problems occur. Avoid such problems.
The parameter lock 1 does not work
For parameter programming, enter the parameters and direct the lock to green mark and then relocate it back. If do not follow the procedure above, the lock does not work.
Q: leakage from O ring or gasket
A: 1. The O ring or gasket is inflated or damaged. Replace them and apply grease to them.
2. Tighten the loose bolts.
2. The rollers are worn. Replace them.
3. The bearings are worn. Replace them
