POSITION AND WARNING (Cont.)
ADJUSTMENT OF NOSE GEAR DOWN LIMIT SWITCH
Gear down limit switch is mounted on horizontal support tube of engine mount that runs between right
attachment points of gear housing and upper drag link.
1. Ascertain that gear is down and locked.
2. Down limit switch should actuate only after leading edge of downlock hook, when moving to locked
position, has passed downlock roller by 0.06 of an inch. (Refer to Figure 27.) Position hook at this
location in relation to roller by moving actuator piston manually toward up position. Downlock spring
may be disconnected, if desired.
3. Loosen lower attachment screw of switch mounting bracket and move bracket toward downlock hook
until it is heard to actuate. Retighten bracket attachment screw.
4. Manually move hook from locked to unlocked position and ascertain that switch actuates at correct
location of hook.
5. Retract and extend gear hydraulically by turning master switch on, raising emergency gear extension
lever and moving gear selector handle to up position. As gear begins to retract, green light below
selector should go out and red gear unsafe light at top of instrument panel (PA-32R-301 SP/301T SP)
or GEAR WARN anunciator light (PA-32R-301 II HP) come on.
ADJUSTMENT OF MAIN GEAR UP LIMIT SWITCH
A gear up limit switch is located in each wheel well above gear door hinge. There is no adjustment of these
switches other than to check that gear, when retracting, will actuate switch within .88 of an inch of full up.
Switch operation turns red gear unsafe light (PA-32R-301 SP/301T SP) or GEAR WARN anunciator light
(PA-32R-301 II HP) out.
