7.0 Knife Installation/Changing
Changing knives can be very dangerous unless safety precautions are
observed and extreme care is taken when handling knives.
•
Make sure knife lifters are used properly, see instructions following.
•
Keep handling of unprotected knives to an absolute minimum.
•
Clear off cutter table before removing knife.
•
Have scabbard nearby and insert knife immediately.
•
Warn people of any unprotected knife.
•
Knife changing is a ONE PERSON OPERATION. Having more than one person trying to
change knives invites accidents.
Figure 11 – Spartan 185 Knife Change Accessories
The knife changing equipment shown in Figure 11
is included with the machine. The following
instructions show how to remove and install a new or re-sharpened knife. Read through these
instructions AT LEAST ONCE before attempting to actually change or install any blades.
7.1 Knife Removal
1. With no paper in the machine, make a cut and when the knife reaches the table, continue to hold
the left cut button while turning off power with your right hand. This will keep the knife in the
down position. Disconnect the machine power cord and remove the right-most knife screw
ONLY. Restore power to the machine, turn the switch on, and the knife should move to the “up”
position. Turn the main power switch off and disconnect the machine power cord.
2. Raise the knife depth of cut all the way up by turning the knife adjusting screw located on the right
side of the machine counterclockwise until it starts to unscrew out of the machine (see Section
6.6 , p. 13). This will ensure the new knife will not cut too deep since a new knife will cut deeper
than one that has been ground several times.
NOTE: Failure to raise the knife depth could damage the new knife and/or the cutting stick.
3. Remove the two knife bolts from the slotted knife bar holes ONLY and replace with the knife lifter
assembly (Figure 12)
.
Tighten the lifters to hold the knife in place, and then remove the
remaining three knife bolts.
