Check And Adjust Track Reverse Tension
May 04, 2018

1. Replace the fuel filter and additional fuel filter after 250H of the new machine; check the engine valve clearance.     

2. Daily maintenance: check, clean or replace air filter element; clean the inside of cooling system; check and tighten track shoe bolts; check and adjust track reverse tension; check intake air heater; replace tooth; adjust bucket clearance; check Front window cleaning liquid level; check and adjust air conditioning; clean the cab floor; replace the crusher filter (option). When cleaning the inside of the cooling system, after the engine is sufficiently cooled, slowly loosen the water inlet cover to release the internal pressure of the water tank before draining water. Do not perform cleaning work while the engine is working. High-speed rotating fans may cause danger. When cleaning or replacing cooling For liquids, the machine should be parked on level ground.      

3, check the project before starting the engine: check the liquid level position of the coolant height (water); check the engine oil level, add oil; check the fuel level (plus fuel); check the hydraulic oil level (plus hydraulic oil); Check if the air filter is clogged; check the wires; check if the horn is normal; check the lubrication of the bucket; check the water and sediment in the water separator.    

4, every 100 maintenance items: arm cylinder cylinder head pin; boom foot pin; arm cylinder cylinder rod end; arm cylinder cylinder head pin; boom, arm link pin; arm cylinder rod end; Bucket cylinder cylinder head pin; half bar connecting rod connecting pin; arm, bucket cylinder cylinder rod end; bucket cylinder cylinder head pin; arm connecting rod connecting pin; check the oil level in the rotary mechanism box (plus (oil); discharge water and sediment from the fuel tank.     

5, every 250H maintenance items: check the final gearbox oil level (plus gear oil); check the battery electrolyte; replace the engine oil sump oil, replace the engine filter; lubrication slewing ring (2); check the fan belt The degree of tension, and check the tension of the air conditioning compressor belt, and make adjustments.     

6. Maintenance items for every 500h: maintenance items for every 100 and 250H at the same time; replacement of fuel filter elements; check the height of slewing pinion grease (grease); check and clean radiator fins, oil cooler heat sinks and cold suspects Fins; replace the hydraulic oil filter; replace the oil in the final gearbox (only for the first time at 500h, 1000h later); clean the air filter inside and outside the air conditioning system; replace the hydraulic oil vent filter.     

7. Maintenance items per 1000h: Maintenance items for every 100, 250, and 500h at the same time; Replace the oil in the rotary mechanism box; Check the oil level of the damper housing (Return oil); Check all fasteners of the turbocharger Check the clearance of the turbocharger rotor; check and replace the tension of the generator belt; replace the anti-corrosion filter; replace the oil in the final transmission case.     

8, every 2000h maintenance items: first complete every 100,250,500 and 1000h maintenance items; clean the hydraulic tank filter; clean, check the turbocharger; check the generator, start the motor; check the engine valve clearance (and adjust) Check the shock absorber.     

9, 4000h above the maintenance: increase the inspection of the pump every 4000h; every 5000h increase the project to replace the hydraulic oil.    

10. Long term storage: When the machine is stored for a long time, in order to prevent the piston rod of the hydraulic cylinder from rusting, the working device should be placed on the ground; after the whole machine is washed and dried, it is stored in the indoor dry environment; if the conditions are limited, it can only be outdoors When storing, the machine should be parked on a well-drained concrete floor; fill the fuel tank before storage, lubricate all parts, replace the hydraulic oil and oil, coat the exposed metal surface of the cylinder rod with a thin layer of butter, and remove the battery. The negative terminal, or the battery is stored separately; according to the minimum ambient temperature in the cooling water by adding a proper proportion of antifreeze; start the engine once a month and operate the machine in order to lubricate all moving parts, while charging the battery; open air conditioning cooling operation 5-10min.
