Adjusting the Operator Presence Control cable (450 and 500 Series
engines only):
1.
With time the OPC cable may stretch and not
fully engage switch which allows the electrical
feed to the spark plug. This is the cable which
runs down from the top bar on the main handle.
2.
Follow the OPC cable down to the back of the
engine where the lever moves when the OPC is
depressed. Come BACKWARDS along the
bare metal cable some 8cms to where the
metal bracket (X) grips the black plastic cable
covering (directly below the fuel filler).
3.
Release the plastic cable cover by compressing
the 2 lugs inwards on the end of the plastic
cable cover that are splayed out and hold it in
place. Feed the black plastic cable cover
BACKWARDS through the bracket to release
the cable.
4.
Disconnect the Z-end of the OPC cable from the
lever which moved when you held the OPC bar
back to the handle in Step 2 above.
5.
Thread a thin washer onto the cable, over the Z-
end of the OPC cable, and then over the 2 lugs
which fasten the cable into the bracket.
6.
Re-connect the Z-end of the cable into the lever
and then replace the cable in the bracket. This
will now compensate for stretch in the cable.
You should now be able to start the mower in
the normal way.
