Permitted replacement knives: 35 x 3 x 630 (TYP 436|100)

The following measures are generally to be applied:
• Thoroughly clean the knives, wedge bars, contact
surfaces on the shaft as well as the contact surfaces
of the adjusting devices.
• Sharpen, hone and balance the knives in parallel.
• Check the knives for straightness and clean grinding
before insertion.
• The adjustment may only be made with PANHANS
adjusting devices (see  13.2.1 or  13.2.2).
• Generally use only high-quality knives.
• The knives (M) may only be sharpened to such an extent that a minimum clamping length of 20 mm can be
maintained with a knife protrusion of max. 1 mm (see  Figure 44).
To replace the knives, use only the PANHANS cutter adjusting devices included in the scope

of delivery or the magnetic quick adjusters (type 1533), which are available as accessories.
