41. attentions ： 1 ） when start the engine, locking level for travelling should be in lock position ， otherwise alarm will occur. 2 ） when do travelling/working operation ， locking level should be in unlock position ， otherwise the bulldozer has no action. 3 ） when stop bulldozer or do maintenance ， locking level should be in lock position to prevent dangerous. Locking for working Locking for travelling Shaft ass’y Operation and maintenance attentions Operation attentions 9

42. Attentions ： 1 ） when start engine ， the key stay at “ START”position should not more than 20s, and second-start should have at least 2min interval. 2 ） When start engine using electric cable ， we should wear glasses ， and first connect positive electrode. When do disassembling, we should first disassemble negative electrode. 3 ） It is very dangerous to make positive and negative electrodes connected, the battery may produce spark or explosion. 4 ） When use other machine’s battery to start engine, do not let two machine connected, and positive connect positive, negative connect negative. Attentions for starting engine Operation and maintenance attentions 9

43. 1 ） Do not open radiator cap when engine is running or coolant has not chill-down to prevent dangerous . 2 ） We should loosen radiator cap slowly to release pressure in radiator. Attentions for radiator Operation and maintenance attentions 9

44. When bulldozer has trouble and can not move ， we can take out reducer’s sun gear shaft and do towing. Attention for towing Operation and maintenance attentions 9

45. Oil cleanliness control piston pump and motor ， electro-hydraulic proportional valve need oil very clean. Oil cleanliness should reach NAS8. Oil contamination Components worn Blocking small passage Components damage Machine can’t work 70% of hydraulic troubles are caused by oil contamination Operation and maintenance attentions 9

46. oil cleanliness control source of oil contamination external contamination assembly contamination internal contamination wear new oil maintenance Operation and maintenance attentions 9

47. oil cleanliness control 4 points to make oil clean Use clean components Cleanliness of pump, motor, valve, tank, pipe should be OK. Use cap to protect oil ports Filtration use clean oil New bulldozer do system filtration to make oil cleanliness reaching NAS8 Clean working space Do not work at dusty environment Change oil and filter on time Operation and maintenance attentions 9

48. maintain on time according to manual book ， otherwise troubles may be appear . Conform to Operation & Maintenance Manual Operation and maintenance attentions 9

49. This type air filter has safety filter and main filter. When air filter indicates it need maintenance ， we only need take off main filter and clean it by compressed air. Do not clean safety filter. After the third cleaning of main filter, safety filter and main filter have to be changed together. We have to ensure that buckle and cap are OK when install filter .Otherwise air may bypass the filter and directly enter engine . Attentions for air filter maintenance Operation and maintenance attentions 9

50. When change oil ， working space should be clean, and don’t do this work at raining or dusty environment to prevent containment going into hydraulic system. All around the maintenance parts have to be cleaned, especially refilling cap ， filter ， fitting ， oil port. Attentions for hydraulic system maintenance Operation and maintenance attentions 9

51. Hydraulic oil type :L-HM46 ( cleanliness should reach NAS8 ) When change oil, drain oil by opening plug on tank. Case of travelling pump and motor have to be inject oil before doing replacing maintenance, and we have to exhaust air in the hydraulic system when restart the engine . filter tank motor pump reducer Attentions for hydraulic system maintenance Operation and maintenance attentions 9

52. Do not directly use water to flush meters and whole of the electric system ， otherwise electric troubles will appear. Earthed contacts should be derusted and check if there is virtual connection Attentions for electric system maintenance Operation and maintenance attentions 9

53. We have to maintain on time according to manual book ， otherwise rust will appear at connecting parts. Lubrication points are at moving parts ， such as blade, ripper, cylinder ， and track . 3 Attentions for lubrication system maintenance Operation and maintenance attentions 9

54. The reducer should not have abnormal sound , and temperature of reducer should not upon 80 ℃ If metal debris appear in drain-oil , the reducer may has trouble and we have to check it. Attentions for reducer maintenance Operation and maintenance attentions 9
