ELECTROMAGNETIC BRAKE
See Figure 10. The Drive Wheel Assembly (4) has a built in electromagnetic brake that is engaged whenever the Master Key Switch (A) is OFF or the FWD /
REV Drive Pedal (3) is in the neutral position. This brake can be manually over ridden if necessary by inserting a medium to large screwdriver behind the Yoke
(AA) as shown. This should only be done in the event you need to push or pull the unit.
