D: Adjusting the micro switch:
1. Hold the OPC bar gently in to the main handle
and listen for a faint click coming from the back
left hand corner of the engine. You are
checking here for a micro-switch engaging
which allows the electrical feed to the spark
plug. If there is no audible click it may be that
the micro-switch is not fully engaged.
2.
In this case, follow the OPC cable down to the
back left hand corner of the engine where the
lever moves when the OPC is depressed.
Come BACKWARDS along the bare metal
cable (2) some 8cms to where the metal
bracket (5) grips the black plastic cable
covering (directly below the fuel filler).
3. Release the plastic cable cover by compressing
the 2 lugs (4) inwards on the plastic cable cover
that are splayed out and hold it in place. Feed
the black plastic cable cover BACKWARDS
through the bracket (5).
4. With a pair of pliers bend the metal bracket
BACKWARDS 4 mm towards the handle. and
then replace the cable in the bracket. This will
now engage the micro-switch by pulling it
further, and you should now be able to start the
mower in the normal way.
E: No response from key start (electric start models only):
Before attempting to start a new engine on the key,
charge the battery for 24 hours continuously (use only
the battery charger supplied with the machine) and then
leave to rest for 12 hours.
Frequent stopping and restarting of the engine may
result in a low battery charge. In this instance it is
recommended that the battery be charged over night
once a month during the cutting season, more frequently
if heavily used.
The battery charger should feel slightly warm if working
correctly when attached to both mains and battery.
