Knife Removal - Challenge CHAMPION 305 Instructions And Parts Manual

8.1 Knife Removal

1. Clear the cutter table. Place chipboard directly under the knife to prevent nicking if the blade
hits the table.
On the screen menu choose "MAINT." and then "Knife Adjust". The menu will lead
you through the rest of this step, then lock out the main power source as shown on
page 6.
2. If equipped with the paper deflector option, lock it down by screwing the lock knob all the way
in Figure 13
3. Back off the knife adjusting screws on the top of the knife bar, (Figure 14), as far as they will
go (counter-clockwise). A new knife will cut deeper than a knife that has been ground several
times. If the adjusters are not backed off, damage can result to the new knife and/or the
cutting stick.
4. Raise the knife.
Press Exit. Push both cut buttons, and the knife will return up.
5. DISCONNECT THE POWER AND LOCK IT OUT, (See Power Lockout Procedure on pg. 6.)
6. Remove the bolts in the two slotted holes of the knife bar and replace them with the knife
lifters. Tighten the lifters enough to hold the blade in place. Remove the remaining four bolts
(Figure 15). The leftmost bolt must be removed while the knife bar is "UP".
