4.21 REEL LIMIT SWITCHES ____________________________________________________
1. Disconnect lift springs. [Section 4.13]
2. Remove cutting unit from lift arm.
3. Use a Volt/Ohm meter to determine when the switch
opens or closes.
a. Adjust magnet (A) so switch just opens with lift arm
at 20° above the horizontal.
b. Switch should close when lift arm is lowered past
20° above horizontal and stay closed for the
remainder of the lowering operation.
c. Switch should open when lift arm is raised past 20°
above horizontal and should remain open for the
remainder of the lifting operation.
d. Repeat test for each front and wing lift arm.
Note:
The limit switches set the point where the reel motors
engage or disengage, not how high they will raise.
4. Reassemble cutting units and lift springs to lift arms.
