the product vary largely and different performance and failure as wel fuel dispenser l. The following just introduce some general methods to solve troubles. 3.1. Inefficient performance The bad separate capacity present as: large foam appears in oil indicator as refueling, accuracy is affected. Maintenance method fuel dispenser s and procedure as followed. Firstly to check the nut and plug on fuel dispenser strainer whether loose, whether leakage at joint face as stopping operation. If failure is still exists after solve the sealing problem of strainer cover, conduct next progress. Check whether pipeline leakage between tank and fuel dispensers. The check method is to disconnect the end cover of strainer, and to find whether exist oil in low pressure chamber; if no oil or oil level go down slowly, there is some leaking places in pipeline or bottom valve. Inspect exhausting valve seat. Open upper cover and inspect the small hole at exhausting valve seat whether stuck. If the hole is stuck or narrowed by waste, oil indicator would appear much foam due to air leaking into vapor separate chamber. The method to solve trouble is that dredge hole and clean groove, making enough area. Note that the area should don’t too large, large room easily causes leaking oil at exhausting pipe. Check vapor separate chamber. Under normal condition oil level in the chamber should keep a half capacity so that ensure air can’t reach into low pressure chamber. (Different products with various oil level). If there is no oil or low level in vapor separate chamber, the taper valve would not plug the hole of return oil valve seat, so as air reaching into low pressure chamber via taper valve and returned oil valve. The solution is that inspecting the axis of returned valve and the hole of returned oil valve seat. Reassembling them after solve problems. 3.2. Exhaust pipe leakage When tank position is higher than that of fuel dispenser, exhausting pipe will leak oil. Plugging exhausting pipe could solve leakage phenomenon. If found leakage on tank the following procedure

situation.　　 EVENT fuel dispenser DESCRIPTION　　 RESUME_FP When the FP is resumed the same transaction continues from where it was paused　　 the state changes to the STARTED state. Only the device that has suspended the　　 fuel dispenser transaction can restart it (for exceptions se fuel dispenser e data variable Suspend_Contr_Id).　　 PCD Comment:　　 If the proprietary pump protocol doesn t allow a suspended pump to be re-started　　 then the PCD should NACK the Resume_FP command (with a MS_ACK=5　　 Data_ACK=5) and stay in the SUSPENDED STARTED state.　　 Action: The FP receives the Resume_FP command.　　 Action : The FP state change is send as an unsolicited data array　　 FP_Status_Message .　　 Action : The FP sends an unsolicited data array FP_Error_Type_Mess　　 with the minor error Fuelling_Resumed to the CD and the error　　 is stored within TR_Error_Code.　　 FIRST-VOLUME- The suspend command was received during the first pulses and the flow meter　　 PULSES registers a preset minimum number of pulses signifying that dispensing has started　　 just after reaching the SUSPENDED STARTED state. The FP moves into the　　 SUSPENDED FUELLING state.　　 Action : The FP state change is send as an unsolicited data array　　 FP_Status_Message .　　 NOZZLE-DOWN The customer finishes a started fuelling (no volume pulses are registered) by　　 returning the nozzle. The FP returns to the IDLE state.　　

from 60 to 65. London s tube drivers regularly threaten chaos in the fuel dispenser capital. A proposed merger of three of the biggest unions—Amicus, the Transport and General Workers Union and the GMB—would create a powerful ‘super-union . Even in the long-suffering armed forces, more familiar as strike-breakers fuel dispenser , there is talk of forming a union. At first glance, that promin fuel dispenser ent union profile sits uncomfortably with the figures, which suggest that trade unionism is a spent force in Britain. In 1979 13.2m workers were union members; today only around 7.5m are, though the decline seems to have halted of late. Just 158,000 working days were lost to strikes in 2005, compared with an average of 7.2m a year in the 1980s and 12.9m in the 1970s. Union membership has collapsed in most rich countries. The decline of heavy industry and the rise of service businesses where labour is highly mobile have made it hard for unions to recruit and retain members. “At one extreme you have individuals who are in such a strong position that they don t need unions to bargain for them,� says Richard Hyman, of the London School of Economics. “At the other you have people in low-skilled, insecure jobs with short-term contracts and a lot of staff turnover.�William Brown, at Cambridge University, points out that globalisation gives bosses a powerful stick to control their workers with “If you have a strike today, the first response of an employer may be to outsource everything.� Only in the public sector—safely insulated from the disciplines of the market—have these forces been resisted. Public-sector unions have received a recent boost from New Labour s spending splurge, which has created 700,000 state-financed jobs. Even so, public-sector workers account for only a little more than a fifth of the nation s payroll. But the union members among them now outnumber their privately-employed comrades (see chart 1). They also do most of the striking (see chart 2). Politics, too, has played its part. Margaret
