During the driving of the excavator, if the transmission "jumps", the machine should be stopped (or continue to drive) in time, and then find the cause and eliminate the fault. The specific method is:
(1) If there is a "jump" when driving on a flat road, you can stop the machine according to the normal shutdown methods, carefully find the cause, and eliminate the fault.
(2) If there is a "jump gear" when driving uphill, you can set the gear to the low-speed position or the first gear position, and wait for the machine to stop when it reaches the top of the slope to troubleshoot; When "jumping the gear", you should stop the machine according to the action essentials and requirements of the ramp stop, and then troubleshoot.
(3) If there is a "jump" when driving on a downhill, you should move the gear to a high-speed position according to the action essentials of upshifting or take measures of "snatch" (emergency downshift), and wait for the machine to drive to the bottom of the slope. Stop the machine again to check and troubleshoot; if the "upshift" and "gear shift" are unsuccessful or "jump gear" occurs again (neutral gear at this time), the driver can control the engine speed at medium speed (to prevent the engine from stalling) , use the "point brake" method to make the machine slide to the bottom of the slope, and then troubleshoot. If the "upshift", the "grab" is unsuccessful, or the "jump" occurs again (this time it is neutral), and the machine is on the downhill slope again (at this time, the machine will go to the bottom of the slope at a very fast speed" "Dive"), you should quickly stop according to the action essentials and requirements of downhill stop, and then deduct the fault.
