A. How to know whether it is oil-leaking:

1. Pull out the sliding stock from vise body before using the vise and under no hydraulic pressure.
2. Check whether it has a gap 1-3 mm or not.
   

B. How to solve oil-leaking issue:

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

MANUAL FOR MC PRECISION POWER VISE

HOW TO USE:

(A) Setting clamping force:

1. Select an adequate clamping force to prevent the distortion or damage of the work-piece. To set the tightening range, align the numerical number of the sleeve face to the mark by the attached wrench as shown in the following figure.
   

(B) Clamping operation:

1. Normal clamping – Turn the handle clockwise to fasten the work-piece.
2. Max. clamping force – In order to accomplish the max. clamping force, please push the handle set after insert into the sleeve end face, and knock the handle lightly until you feel resistance. Then, release the handle and turn the handle clockwise once again. The max. clamping force can be accomplished as follows.
   
3. Unclamping – Released easily by turning the handle counterclockwise.
   
   

CAUTIONS FOR USE

1. Don’t hit the handle with a hammer, while fastening.
2. Check the flatness of the bottom face of the vise in order to prevent the damage and dirt. Coat the surface and upper surface with machine oil regularly.
3. Clean the slide cover way.
4. Remove the first slide cover and clean, if the swarf and dust enter inside cover.
