PARTS REMOVAL AND REPLACEMENT
5. Tilt the machine forward and use an extended socket to remove the
two handrail adapter screws from the front leg of the machine.
6. Tilt the machine back into place and pull each handrail out sideways.
Be aware that the handrail extrusion connects the left handrail to the
right handrail, and may fall out when one side is removed.
7. Reverse the removal procedures to reinstall the handrail.

attached to the alternator (see Final Assembly Diagram). Remove the
wires from the alternator.

the alternator from the frame.
4. Reverse the removal procedures to install the new alternator. Be sure
to verify the wiring against the Final Assembly Diagram.

(0.6 cm) of belt deflection with finger tip pressure at the center of the
vertical portion of either side of the belt (see Figure 27).
