4、電。Cautions about accumulator 蓄電池 注意 ！ The + and - poles of accumulator must be clear before changing accumulators or using other assistant powers. + pole of new accumulator or assistant power should be connected to + of the old one,the same as the - pole. If the poles are connected wrong,serious dam

5、ages even fires will occurred to the circuits and generator! 更換蓄電池或使用其它輔助電源起動發動機時,必須將蓄電池“+”、“”接線柱辨別清楚后, 再把蓄電池“+”、“”接線柱上的連線分別接到新蓄電池或輔助電源的“+”、“”接線柱上，絕對不允許接反；否則將引起燒毀線路和發電機的嚴重后果, 還可能引起火災! 1.1.2 Generator 硅整流發電機 This generator uses silicon diode as commuting component and changes mechanical energy into e

6、lectrical energy. When the generator works properly, it can provide power to electrical equipments and provide the extra power to accumulator as storages as well . 硅整流發電機是用硅二極管作整流元件的發電機，作用是將機械能轉變成電能，正常工作時，一方面向用電器件供電，另一方面將多余的化學能供給蓄電池儲存備用。 1.1.3 Main Power Switch 電源總開關Cautions: While the engine is run

7、ning, it is forbidden to shut off the main power switch.If it is done like this,the connections between accumulator and generator will be destroyed, the generator will lose a good smoothing element.The instant high voltage will puncture the adjustor and the semiconductors inside the generator and ca

8、use the damage of generator. 注意：當發動機運轉時，絕不允許切斷電源總開關，否則將損壞發電機（和調機器），因切斷后，蓄電池與發電機之間的聯系被切斷，發電機失去了一個良好的濾波器件，但發動機仍帶動發電機發電，瞬間的過電壓將擊穿調節器和發電機內部的半導體元件。 1.1.4 Ampere Meter 電流表 Ampere Meter is used to indicate the power conditions of charging and consumptions. The hand of Meter leaning to + means charging , th

9、e hand leaning to - means consumption. If the hand leans to + while the power is consumed, this means that poles of Meter are connected wrong and needs to exchange. When the main power switch is turned on, it is ok if the hand leans a little to the direction of -. If the hand moves to the bottom of

10、the direction of -, it means that the circuit must be grounded. The main power switch should be shut off at once and switches on again only after having found and resolved the problems. 電流表是原來指示充電和用電情況的。 一般，指針偏向“+”，表示發電機給蓄電池充電；指針偏向“”，表示蓄電池向用電器件供電。若偏向“+”為用電的話，則電流表正負極接反了，應對換正負極的接線。合上整車電源總開關，駕駛室儀表板上的電流

11、表指針向“” 方向稍微偏轉是正常情況。若電流表指針向“” 方向偏轉到底，說明電路有接鐵故障。應立即切斷電源總開關，尋找并排除故障后方可再合上。 1.1.4 Ampere Meter 電流表After starting the engine, the hand of Ampere Meter in the cab leans to + in a certain time,it means that the generator is charging the accumulator.The deflection angle of the hand is wide at the beginning

12、and then reduces gradually. If the circuit is under light load or no load,the hand of the Ampere Meter deflects lightly or does not deflect at all.This mean that the power system works rightly.If the deflection angle is always in wide position,this means that there are something wrong with the circu

13、it.If the engine works properly and the hand of Meter leans to - indicating discharging,the problem is that the generator does not charge or there are something wrong with the Ampere Meter.發動機起動運轉后，在一段時間內，駕駛室儀表板上的電流表指針偏向“+”，表示發電機向蓄電池充電，開始偏轉角度大，隨后逐漸減小，在電路無負載或輕負載的情況下，電流表指針偏轉很小，甚至不偏轉，這說明電源系統正常。若電流表指針偏轉

14、角度一直較大，表示電路有故障。若發動機已正常運轉，而電流表指針仍偏向“”，指示放電，最大可能是發電機不發電，其次就是電流表本身有故障。 1.2 1.2 Start-up Unit Start-up Unit 起動部分起動部分Including 包括1.2.1 Starter 起動機1.2.2 Igniter 點火開關 1.2.1 Starter 起動機 In fact, the Starter is a series excitation and DC electromotor. 起動機實質為一個串激直流電動機，將電能轉為機械能，用以起動發動機。 Cautions about Starter!

15、 起動機起動機 注注 意意 ! The Starter is designed according to interruption work and the current may reach several hundreds Ampere please pay attentions to the following : 由于起動機是按短時間斷續工作而設計的，且工作電流達數百安培，所以應注意以下事宜： l The duration of starting should not exceed 5 seconds. Only after 3 minutes stop, you can restar

16、t the engine, otherwise the lives of the accumulator and starter will be shortened or be terminated. 每次起動時間不得超過5秒，重復起動應停歇3分鐘以后進行。否則將縮短蓄電池和起動機的壽命，甚至當場損壞； Cautions about Starter! 起動機起動機 注注 意意 !l In cold winter, start the engine after preheated or according to the instructions of starting engine in col

17、d weather. 在寒冷的冬季，應待發動機預熱后再起動，或嚴格按冷起動操作規程起動。 l If the engine can not be started for three times, stop operations and inspect the troubles at once. Restart the engine again only after all troubleshooting. 若連續起動三次都失敗，應立即進行檢查，待故障排除后再起動。l Loosening the starting switch at once after the engine was starte

18、d in case of any damage to the starter. Do the same thing at the driller console.起動后應立即松開起動按鈕（或旋鈕），避免損壞起動機。司鉆控制箱上的起動按鈕操作也應如此。 1.2.2 Ignition Switch 點火開關 Its function is to switch on the Starter.At normal condition,the ignition switch can be pressed down or circumrotated easily and can spring up auto

19、matically without any block after loosening hand. If there are something wrong with the switch,it should be repaired or replaced.If the switch can not spring up automatically,it may destroy the Starter. 它是用來接通起動機的。正常情況下，起動按鈕應能輕松地按下（或旋轉），松手后應立即自動復位，不得有卡阻現象發生，如有異常應予修理或更換，否則將影響起動；若按下（或旋轉后）不能自動復位，有可能損壞起

20、動機。當用點火開關起動檔時，也應如此。 1.3 Lighting and Signals 1.3 Lighting and Signals 外部照明和信號裝置外部照明和信號裝置1 11.3 1.3 Lighting and Signals Lighting and Signals 外部照明和信號裝置外部照明和信號裝置2 21.4 1.4 Speakers,Sound and light alarming systemSpeakers,Sound and light alarming system音響及聲光報警裝置音響及聲光報警裝置 Electrical Speaker can make sou
