13.0 Repair and Replacement

13.1 Fuses (skip this section if the machine has Circuit Breakers)

The Champions each have a set of fuses. The fuses are located inside the main power box, (Figure
48). Check the label inside the cover for correct ratings for these fuses. Labels are reproduced with
the drawings at the back of this manual in case those on the cover may be damaged or illegible.

13.2 Knife Cylinder Replacement

Replacing the Knife Cylinder:
1. Remove the knife from the cutter (see Knife, Installation and Set Up).
2. Place a 3" (60mm) lift of paper under the clamp only to hold it up and out of the way of the
knife bar. Then place a 3' (1 meter) long 2x4 board flat side down under the right end of the
knife bar. This will be used for leverage on the knife bar when removing and reinstalling the
knife bar pin.
3. Lock the clamp and knife down by following instructions in the Operator Controls section for
your particular model of machine.
4. Turn off the main power disconnect switch. DISCONNECT POWER AND LOCK IT OUT!
See page 6.
5. Place a pan underneath the cylinder and gradually loosen and remove the hydraulic hose
connections (Figure 49). Loosen the connections slowly to bleed off any trapped pressure.
