5. Replace bottom cover. Turn on power and make a cut. Check position of knife – USE
CAUTION, THE KNIFE EDGE IS VERY SHARP. The edge of a new knife should be above
the bottom of the clamp when the knife and clamp are in the “up” positions. If the knife edge
is below the clamp, repeat the adjustment procedure, moving the bracket slightly in the
direction that allows the knife to come up further. NOTE: The knife should not be able to
come up so far that the gears become disengaged – or damage to the machine could result.
3.5.13 Knife-Down Limit Switch Adjustment (All Models)
The down limit switch is normally adjusted by the operator from the exterior of the machine. No
internal adjustments can be made, but the switch can be checked to ensure that it is functioning
properly.
To check switch assembly:
1. Turn off the power and disconnect the power cord.
2. Remove rear bottom cover.
3. Check all bracket and switch hardware to make sure they are tight (Figure 20).
