This maintenance guide applies to this small diesel wheel loader with a rated load capacity of 2000kg. It is equipped with a YN38GBZ engine, four-wheel articulated drive and 16/70-20 engineering tires. Following daily, weekly, monthly and seasonal maintenance procedures strictly can extend the overall service life of the machine, reduce downtime caused by malfunctions, and ensure stable and efficient loading operations on farms, construction sites, yards and orchards. Before all maintenance and inspection work, shut down the engine and release hydraulic pressure to guarantee operation safety.

Break-in Period Maintenance for New Machines (First 60 Working Hours)

Do not operate under full load during the break-in period, and avoid long-time high-speed driving.

After the break-in period ends, fully tighten all bolts of transmission shafts, drive axles and wheel rims, replace the initial engine oil and filter elements, and refill grease at all machine lubrication points.

 I. Daily Maintenance (Before and After Each Operation)

 1.1 Pre-operation Full Machine Inspection

1. Check the engine oil level. Pull out the oil dipstick; the oil level must stay between the upper and lower scales of the dipstick. Add special diesel engine oil of the same model if oil is insufficient. Replace the oil immediately if it turns black or contains impurities. This machine is fitted with a YN38GBZ vertical inline water-cooled four-stroke diesel engine, which outputs 76KW power at a rated speed of 2400 rpm. Sufficient and clean engine oil is the foundation for stable power output of the engine.

2. Check the coolant level of the radiator. Add antifreeze coolant in winter and clean soft water in summer. Insufficient coolant will lead to engine overheating and sharp power loss, making long-hour full-load operation impossible.
