Failures of the mower push-pull switch:  
Alamo has recently received reports of failures of the referenced switch. The failures  
modes are:  
(a)  
(b)  
Knob pulls off rod.  
Rod and Knob pulls out of switch body.  
Test performed on numerous switches indicates that the (b) failures are due to excessive  
force being applied to the knob when shutting off the mower. Specifically, the knobs are usually  
roughly slapped to turn the mower off. After internal parts of the switch are damaged, the rod can  
then be pulled out easily. The (a) failures are due to the knobs not being securely tightened.  
To prevent these failures from occurring, or to replace a damaged switch, use the following  
procedure to adjust the travel of the switch. (See attached diagram).  
1.  
2.  
Install the switch body in the holder and tighten the nut.  
Screw the Knob on the rod to the bottom of the thread, but do not overtighten. It  
will probably be necessary to hold the rod with pliers to get the knob tight, if you do  
use caution not to score the rod with the pliers.  
3.  
Measure the distance (if any) between the knob and the nut. Record the  
measurement.  
4.  
5.  
If a Gap exists between the knob and the nut, remove the knob.  
Remove the nut and install the same thickness of flat washers that was  
measured in step 3. Install and tighten the nut> DO NOT install more washers  
thanneededtotakeupthespace.FlatWasherPartNo.00023500orequivalentcan  
be used.  
6.  
Install the Knob, using Locktite or similar thread locking compound. Thread the  
knob on the rod all the way. Test to make sure that when the switch is "Off" (with  
rod pushed in) that the knob can not travel further into the switch.
