How to adjust cutting edge height M 1. Assemble all related parts into the cutter. Make the back end of 2. Make sure the back end of cartridge makes contact cartridge contact with Wedge screw adjustment screw with adjustment screw (Fig. 1), and pull them lightly inwards (Fig. 2). Wedge Tighten the cartridge clamp screw temporary. Adjustment screw Insert Cartridge 3. Install the insert (Fig. 3), and tighten the wedge clamp screw screw temporary. Fig. 1 Temporarily tighten the screw with a 40 to 45 degree rotation after the wedge contacts the insert. 4. Loosen the cartridge clamp screw. (Fig. 4) 5. Adjust the extruding amount with adjustment screw. (Fig. 5) Fig. 2 Fig. 3 6. Tighten the wedge screw and firmly fix the insert. (Recommended tightening torque: 6N·m) Cartridge clamp screw 7. Tighten the cartridge clamp screw firmly. (Recommended tightening torque: 10N·m) Wrench

Notes: 1. Follow steps 1 ~ 7 above for adjustment. 2. To adjust the edge height adjust the wedge screw and loosen the cartridge clamp screw.

Tightening the adjustment screw with the clamp screw fixed firmly may damage the Fig. 4 Fig. 5

adjustment screw. 3. The adjusted edge height difference must be within 5µm.
