3.5.14 Re-engaging the Knife Pull-Down Gear (All Models)
If the knife pull-down gear becomes disengaged, the following procedure must be followed in order to
properly re-engage it:
1. Turn off the power and disconnect the power cord.
2. Remove rear bottom cover. It may be helpful to lower electrical panel and slide forward (see
Section 3.4 Accessing the Electrical Panel, page 12).
3. Disengage the motor brake by holding the brake lever either up or down (Figure 21).

4. With the brake disengaged, move the gears in the directions shown in Figure 21. The
smaller gear has a small stub on it which can be used to turn the gear using a pair of pliers or
locking pliers if necessary. If the larger gear cannot be moved by hand, tap on it with a
rubber hammer or carefully pry it with a long bar. Be very careful not to damage the gear
teeth. Rotate the gears so that at least one whole tooth is engaged (Figure 22, page 25).
