Wing Switch Replacement

1. Park machine on a level surface, engage parking
brake, lower the cutting units and turn engine OFF.
2. Remove deck covers.
3. Disconnect wing switch electrical connector.
4. Remove boot, spring, nut and washer, then remove
the wing switch. Disconnect wiring assembly from
switch terminals.
5. Install wire assembly on new wing switch. Make sure
that one wire is connected to the "COMMON" terminal,
and one wire is connected to the "NORMALLY OPEN"
(N.O.) terminal.
IMPORTANT: The wing switch has three (3) termi ­
nals. If the two (2) wires are not connected to the
"COMMON" and "NORMALLY OPEN" (N.O.) termi ­
nals, the safety interlock circuit will not function
properly.
CAUTION
If the wires are not correctly installed to the
switch, the wing deck could operate when in
the raised position.
6. Coat switch terminals and wires with skin-over
grease.
7. Install new switch. Apply Loctite 242 or equivalent
switch threads before installing nut. Tighten nut to a
torque of 75 - 100 in-lb. Install spring and boot.
