WARNING
Before performing any type of maintenance/service, disengage all
controls and stop the engine. Wait until all moving parts have come to
a complete stop. Disconnect spark plug wire and ground it against the
engine to prevent unintended starting. Always wear safety glasses during
operation or while performing any adjustments or repairs.
Follow the maintenance schedule given below. This chart describes
service guidelines only. Use the Service Log column to keep track of
completed maintenance tasks. To locate the nearest Sears Service
Center or to schedule service, simply contact Sears at

MAINTENANCE SCHEDULE
NOTE: If you’re replacing the friction wheel assembly as a whole,
discard the worn part and slide the new part onto the hex shaft.
Follow the steps above in reverse order to reassemble components. If
you’re disassembling the friction wheel and replacing only the rubber
ring, proceed as follows:
Remove the four screws which secure the friction wheel’s side 1.
plates together. See Figure 32.
Remove the rubber ring from between the plates.2.
Reassemble the side plates with a new rubber ring.3.
NOTE: When reassembling the friction wheel assembly, make sure
that the rubber ring is centered and seated properly between the side
plates. Tighten each screw only one rotation before turning the wheel
clockwise and proceeding with the next screw. Repeat this process
several times to ensure the plates are secured with equal force
(between 6 ft-lbs and 9 ft-lbs).
4. Slide the friction wheel assembly back onto the hex shaft and
follow the steps above in reverse order to reassemble
components.
5. Perform the Drive Control Test outlined earlier in the Service and
Maintenance section.
