    ser. Axis of transducer is much flexible; installing damp seal could reduce the flexibility of shaft. Impotent spring of check valve make oil flow backward even after stop operation, which bring transducer rotating conversely. Pressure oil flow back to transducer, bring negative round. The double optical board has installed wrongly, making data jumping. Automatic stop failure as presetting volume First define which situation trouble occurred ---- in presetting volume or in presetting money. If the former is trouble, reenter unit price. If both trouble, it is need to replace new main board. Loudspeaker trouble In most case, loudspeaker is destroyed. The static voltage of SP terminal of loudspeaker is 0 V; if the data fuel dispenser is 12V, maintainer needs to replace or repair both loudspeaker and main board. Damaged main board and wiring board also result in loudspeaker failure. Small flow lost before stop operation Much little adjusting volume of main valve; Control lead of main valve is incorrectly connected to relative position; Small flow rate is lost due to main board trouble. Stop failure as put down nozzle The silicon on control board is damaged. Switch has destroyed. Abnormal MT voltage leads to the trouble. Lack of phase in motor Lack of electric phase in motor makes alarm. Electric phase is absent in junction box. Creepage Inner winding of motor id damage fuel dispenser d. Water pours into junction box or insulation decline. Outer wire is connected with the frame of fuel dispenser. Creepage of inner electric circuit due to other reasons Reliable protective circuit and earthing aren’t set in fuel dispenser. Fuel dispenser’s creepage easily result in fire and body hurt accident. Only after solve the trouble can operate fuel dispenser. Article II Pipeline failure and maint fuel dispenser enance No delivery or slow flow Filter net is jammed because of mud and sand, metal bits and waste. Cleaning filter net would deal with the trouble of loud noise and no delivery. Large amount of air flo

    er needed to pacify Iraq, but the maximum number that can easily be dispatched there. Donald Rumsfeld, the defence secretary, has sorely limited the number of American troops in Iraq and Afghanistan. But to succeed, as Iraq s security forces continue to disappoint and sectarian killing mounts, America needs to send more. How many more, and for how long, must be for the generals to decide. Wherever American troop numbers have been increased in Iraq, security has been improved, at least for a while. At the same time, it is vital that any increase be kept to a minimum. Three and a half years since the invasion American troops remain brutal peacekeepers, winning few friends with their trigger-happy ways. And the strategy of p fuel dispenser ushing Iraqi forces to take responsibility for their country is sound. But at least one additional American division, around 20,000 men, is needed in western Iraq, according to the leaked estimate of the American commander there. A similar number are probably required in Baghdad, where last month reinforcements of 12,000 American and Iraqi soldiers had small success in taming the madness. Finding these extra troops will be difficult and costly. Even to maintain its current numbers in Iraq, America must break yet more promises to its over-stretched soldiers. It will have to extend combat tours, shorten the intervals between them and perhaps, as a last reso fuel dispenser rt, increase the stipulated 24 months for which the National Guard and the reserves may be deployed. Meanwhile, to ease the strain, it should increase the army s authorised size by at least 30,000 soldiers, the number temporarily added to the force by Congress earlier in the war. With luck, by the time those troops are ready, they will not have to be sent to Iraq or Afghanistan. But they will still be needed.
