 a: Check if the pre-pressure is in the available condition before using.

     Inspection methods: 

    1. Pointer is not at zero, and there is left pre-pressure

    2. Manually check the pressure gauge and if the      

        body turns

        if so, it means there is left pre-pressure. 

        Otherwise, 

        if don't, that means there is no 

        pre-pressure.

b: Method of reloading pre-presssure of dynamometer

    1. Remove the screw B.

    2. Loosen the pull stud A and loosen it again.

    3. Push the pull stud A inwards (so that the oil level is reduced).

    4. Fill R68 hydraulic fluid from hole B and then tighten the screw B. 

    5. Tighten the pull stud A. In the same time, Pointer C will be moving upward.

       As the pull stud A is fully tightened, the proper pressure indication will be 

       between 10 to 30kg. 

       If it is over 30kg, loosen Screw B and let the indication be 10 to 30kg  

c: Method of dynamometer dial indicator reading

   1. The inner area of the dynamometer 10.00875 m㎡, so when the indication 

      times 10 is the correct pulling force.  

   2. An unit of dynamometer equals to 10kg  

   3. The digital dynamometer uses the Newton as 1 unit. (1kg = 9.8 N)

d: Method of pull stud replacement

    1. Use the adjustable wrench to clamp the seat of "D"

    2. Turn the A lever ("D" to hold )

    3. Replace the new lever A and lock it again.

    4. Check the preload again, if the preload is normal, 

         you can continue to use it.
