TO ADJUST ATTACHMENT CLUTCH
The electric clutch should provide years
of service. The clutch has a built-in brake
that stops the pulley within 5 seconds.
Eventually, the internal brake will wear
which may cause the mower blades to
not engage, or, to not stop as required.
Adjustments should be made by a Sears
or other qualified service center.
1. Make sure attachment clutch and
ignition switches are in =OFF" position.
2. Adjust the three nylon Iocknuts until
space between clutch plate and rotor
measures .012" at all three slot
locations cut in the side of brake plate.
