Introduce the daily routine maintenance of the loader (daily)
1. Check the water volume of the water tank, the amount of fuel oil and the oil volume of the operation tank.
<Once every ten hours; see what you do in detail; different loader fuel tanks are different in size, old forklift fuel tanks can not see the filter screen; new loaders have fuel gauges; only see from below when the amount of fuel is low; generally no fuel tank How much oil is there; see the hydraulic oil every day
2. Check the tire pressure and shape. "If you want to know the loader condition, you don't need to check every day;"
3. Check the operation organization and whether there is no shortage of signal equipment.
"If you want to know the vehicle condition, you don't need to check every day;" 4. Check the amount of engine oil, whether there is any abnormality after initiation, and whether the operation of each instrument is normal. "If you understand the loader conditions, you should pay attention to cold loaders and hot loaders, whether there are changes in different climates;"
5. Whether there is oil leakage, air leakage and water leakage in each part.
6. Whether any fasteners are loose or dropped.
First-level maintenance (weekly), with smooth fastening as the main point, do a good job of "three filter" cleaning operations.
1. Add smooth grease to the grease nipples of the whole loader. "It is necessary to add smooth grease to work equipment every day. Others can be extended appropriately "
2. Check whether the tightening bolts and nuts are loose.
3. Clean the air filter, fuel filter, etc. "If the fuel filter does not work, it is often opened to avoid leaking the fuel if the seal is not tight. Can cause problems with the oil circuit; check the air filter depending on the operating environment; generally increase the black smoke when refueling should check the air filter
3. Check whether the clearance and stroke of the brake pedal, transmission operating lever, and accelerator pedal meet the requirements. If they do not fit, they should be adjusted.
4. Check the bucket, boom and rocker for damage and looseness.
5. Check the height of the battery liquid level and the specific gravity of the electrolyte. "After 06 years, it is useless to watch the battery without protection; as long as the head is tightened and greased,"
Secondary maintenance (monthly), with adjustment as the main point, add the following maintenance on the basis of primary maintenance;
1. Check the oil level of the gearbox, drive axle and wheel reducer to make up for the lack of oil.
2. Check the wear status of brake pads and adjust them. "No adjustment can only be replaced; and to see whether it fits the replacement cycle; if it does not match, you should check the cause of early wear"
3. View the steering organization.
4. Replace the engine oil.
Seasonal maintenance, seasonal climate changes every season, and seasonal adjustments to the whole machine.
1. Winter: engine, torque converter, gearbox, drive axle, operating hydraulic system, replacing low viscosity oil. Increase generator power generation, etc. "The viscosity of the engine oil is not too low, depending on the amount of detailed work; too low is good, the oil pressure is lacking after a large amount of starting work; the viscosity is not good enough to start, but the oil pressure can guarantee long-term operation;" "The generator power generation cannot be increased by most Adjust the fan belt or replace the belt "
2. Summer: Engines, torque converters, gearboxes, drive axles, operating hydraulic systems, replacing high-viscosity oils. In addition, for the cooperative operation organization, the wear status of the operation distribution valve and the cylinder should be checked. If the wear is severe, it must be corrected.
The following content needs professional maintenance; beginners can look at it;
Balance maintenance, mainly to eliminate the unbalanced wear of each assembly. The following maintenance is added on the basis of secondary maintenance.
1. The gearbox, torque converter, drive axle, and operating hydraulic system are all replaced with new oil, and the pipeline, oil tank, filter, etc. are cleaned.
2. Check whether the pins and bushes are damaged or loose, and correct or update them.
3. Check the connection status of the front and rear axles and the operating equipment and frame. If there is any looseness or damage, tighten and repair it.
Overhaul and maintenance. Perform crash review on the engine, transmission, drive axle, steering system, braking system and working equipment, replace wearing parts, correct the deformation of the stressed parts, and perform restorative repairs. When the loader repair plant is used for the first time after being placed for a long time, in addition to viewing the vehicle according to the first-level maintenance, special attention should be paid to the inspection and maintenance of the engine.
