Disposal of on-board spare parts jump while driving.
_1. "Gear jump" occurs when driving on downhill. The gear position should be put in high speed position according to the main points of upshift action or take measures of "emergency downshift". After the machine drives to the bottom of the slope, stop to check and correct the fault; If "upshift", "gear-up" is unsuccessful or "gear-off" (in this case neutral) occurs again, the loader accessory driver can control the engine speed at medium speed (to prevent the engine from stalling), slide the machine to the bottom of the hill by means of "brake-on" and then correct the fault. If "upshift", "gear-up" is unsuccessful or "gear-off" (then neutral) occurs again, when the machine is on a downhill slope (at this time the machine will "dive" rapidly towards the bottom of the slope), it should stop quickly according to the main points and requirements of downhill stopping action, and then deduct the fault.
_2. "Gear jump" occurs when driving on flat roads, which can be stopped according to the main points of normal stopping. Carefully find out the causes and correct the faults.
_3. "Gear jump" occurs when driving uphill. The gear position can be put in the low speed position or the first gear position. Stop the machine after driving to the top of the hill to correct the malfunction; If deceleration is unsuccessful or "gear jump" occurs again, stop according to the action essentials and requirements of ramp stop, and then troubleshoot.
_During the process of using loader, there are some minor problems due to the problems of loader accessories. We need to understand some issues to maintain ourselves and prepare some loader accessories at the same time.
_Loader is in gear, but the loader is weak and can not even walk. The reasons are as follows:
_1. Clutch piston rings, sealing rings are severely worn and leaking.
_2. Clutch automatic empty valve is not tightly sealed to reduce pressure;
_3. The shut-off valve cannot be returned;
_4. Severe wear of friction plate and excessive clearance;
_5. Fatigue or breakage of shift valve positioning spring, steel ball runs out;
_6. Shift control valve pipeline blocked;
