REMOVING THE ANVILS
The chipper features both a vertical and horizontal
anvil. To remove the anvils, open the fastening bolts (A)
and (B) (M12). The horizontal anvil fastening bolt (B)
is located below the feed opening. Fig. 16.
SHARPENING THE ANVILS
If you notice wear or rounding of the inner edge
of the anvil, sharpen the anvils so that the original angles
are retained. Fig. 17.
INSTALLING THE KNIVES AND ANVILS
• Check the condition of the fastening bolts and nuts.
• Install the knives and anvils and tighten the
fastening bolts to the torques specified in table.
• Adjust the knife-to-anvil clearance.
ADJUSTING AND CHECKING THE KNIFE-TO-ANVIL
CLEARANCE
The need for adjusting the anvils is determined by the
amount the knives are sharpened. Always check and, if
necessary, adjust the clearance between knives and anvils
• after a heavy sharpening;
• if the knives were removed - for example, due to
sharpening;
• if new knives are replaced,
• if chip length is adjusted.
Check the clearance with a feeler gauge.
1. Loosen the M12 locking screws (A) and (B) of the
anvils. See fig 18.
2. Turn the cutting disk in such a way that the
front edge of the knife is exactly opposite the ver-
tical anvil. Slide a feeler gauge between the knives.
3. Tighten the screws of the anvil (A).
4. Adjust the play of the horizontal anvil towards
the front edge of the knife to 1.2-1.5 mm.
5. Tigthen the locking screw (B).
6. Recheck the knife play.
