How old digging machine used in accordance with procedures to adjust the tension of the track: (1) loosen the track: with a long socket wrench slowly counterclockwise rotary valve 1. To loosen track, in accordance with a long socket wrench counterclockwise slowly rotated directional valve (1), grease from the grease outlet. 2, turn on the valve (1) lap to lap and a half, it would be sufficient to loosen track. 3. If the grease can not be discharged smoothly, hand digging machine price information, the track off the ground, and slowly rotating track. 4. After obtaining the proper track tension degree, second-hand excavator quotes and pictures, in a clockwise direction of the valve (1) and tighten to 147 cattle × m (15kgf × m). Note: Do not fast or excessive release valve, fine hand digging machine sales, otherwise the grease in the regulation of the hydraulic cylinders will emit. Care should be taken to put the valve (1) is released and can not be against the valve body or facial oil for diesel engines used in construction machinery, such as CF-4 grade of oil, of which C represents the diesel engine oil; F representative of the quality grade increments every letter, the performance of the oil will be one of the letters the more reliable, higher quality level than before; "- 4" riser grade, second-hand digging machine is an engine oil performance, at the same level of oil in the digital The larger, the better the quality. For imported models in the choice of oil is required in accordance with its engine fueling mode to choose: the choice of direct-injection turbocharged engine CF-4 grade oil can; EFI supercharged engine you need to use the CH-4 rating or higher grade oil to ensure the normal operation of the engine.
