1. cutting machine horizontal walking crawling. Reason: the oil tank oil surface is low, there is air in the cylinder. Exclusion method: fill the tank with oil, loosen the tubing bolts at both ends of the cylinder, start the motor, press the left and right switches to exhaust. 

2. cutter head slides after the cutter stops working. Reason: Pressure system valve closure is not strict. Removal method: drop the cutter head of the cutting machine to the bottom dead point, power off, remove the DF-B10K right angle valve and the YF-B10H4 relief valve, separate the right angle valve and relief valve to clean the original with clean kerosene. After cleaning can be restored to install, if the original wear, must replace the new. 

3. oil spill Cause: The sealing ring is broken. exclusion method: replace the new sealing ring. 

4. rise or fall Cause: yf-b10h4 relief valve adjustment is too tight. 34 bm-b10h-t solenoid broken. Exclusion method: Rotate the relief valve handle to return the speed to normal working speed. Remove the 34 bm-b10h-t solenoid electromagnet, remove the damaged thimble and replace the new thimble. If this happens on the left and right, it is excluded. 

5. cutter head guard without water. Reasons: cutter head guard outlet hole blockage: water selection switch damage; intake pipe filter block; water pump or power burn out. Elimination: Remove the cutter head shield and remove the clogging with fine wire. check select switch if damaged replace new. Check if the pump or power is burned out if burned out replace the new one. 

6. got stuck cutting a blade Cause: belt loose, cutting piece aging, bearing damage. current overload protector current adjustment is too large. Exclusion method: adjust the belt tensioning wheel, tighten the belt, such as belt aging, replace the new. If the cutting piece is aging, replace the new cutting piece. Check 207 bearing if damaged, replace new bearing. Turn the current overload protector down.

 7. there's no manual action No manual left action, check manual left button and bracket left stroke switch is damaged. 2, no manual right action, check manual right button and bracket right stroke switch is damaged. The above original and the line no problem, check whether the action electromagnet stuck coil burn. 

8. problems and elimination methods in automatic cutting When cutting automatically, the drop is not right, because the drop stroke switch is not separated or the stroke switch is damaged. 

Exclusion method: adjust the bolt under the touch iron and bracket plate to make the blade in the right position, set the stroke switch to separate, replace the stroke switch. Do not rise to the right end when cutting automatically. The reason is that the guide rail mud too much can not walk the position of the separation stroke switch, lubrication is not in place, the right end stroke switch damage. Exclusion methods: clean up the sludge, inject lubricating oil or replace the stroke switch. If it is not the above problem to increase the pressure of the oil pressure system. inaccurate metering of 

9. meters Cause: The transcoder and meter are damp or aging. exclusion method: blow dry with electric blow. Always watch out for moisture. Replace new appliances.
