Vise
A. How to know whether it is oil-leaking:
- Pull out the sliding stock from vise body before using the vise and under no hydraulic pressure.
- Check whether it has a gap 1-3 mm or not.
B. How to solve oil-leaking issue:
- Please take out two screws and washes (No. 1).
- Take out whole set of oil filler bolt (No. 2).
- Pull out whole set of cylinder kit (No. 3).
- Use magnifier to check whether oil seals are broken or not.
- Use naphtha to clean the hole 41 mm (No. 4) where cylinder kit can put in, and then dry it by compressed air.
- Even spread grease on the cylinder kit, and then put it in the hole 41 mm.
- Keep a gap 2-4 mm and slant the sliding stock a little bit, then fill oil in.
- Shake sliding stock lightly to let air come out from oil hole. Please ensure there is no air inside the oil hole.
- Screw whole set of oil filler bolt (No. 2), and then screw two screws and washes (No. 1) tight.
- The last step is to install spindle, fix tube nut, and the vise body. After installation, please check its clamping force again.
