WARNING
I
WARNING: Do not bypass, modify, alter, or
disconnect the safety system. Make sure that the
safety interlock system is fully operational each time
before mowing. Failure to do so could present danger
to you and others around you.
There are generally three (3)ways to adjust the
sensitivity of a safety switch. The most appropriate way
to adjust each switch depends upon the application,
location, and the nature of the problem you are
encountering.
Method 1: Adjust location using the mounting screws
1. Move the blade control lever to OFF.
2. Loosen screws (A) until safety switch (B) moves
freely.
3. Slide safety switch (B) firmly against blade bell
crank (C).
4. Tighten screws (A) and check that safety switch (B)
does not move.
Method 2: Adjust location using adjustment nuts on
switch body
1. Loosen locking nut(C) onthe sensor shaft.
2. Adjust switch location by turning the nuts.
3. Tighten the locking nut when proper adjustment is
achieved.
Method 3: Relocate mounting holes
In rare cases where the components become
misaligned, the easiest means of adjusting the location is
to elongate the existing holes or add new holes to
achieve a tighter fit between the activation rod and the
sensor.
