Maintenance and Troubleshooting

14.2.3 Sensor spot replacement

3. When unscrewed completely simply lift out the old

sensor spot. Pull off the maintenance tool and

discard the old sensor spot.

4. Check the red O-ring (position indicated right). If it

appears damaged in any way, then using a pair of

tweezers, remove and replace it with the new

O-ring from the maintenance kit.

NOTICE

Avoid scratching or damaging the sensor spot (the

black surface on the sensor head) during this process.

1. Push the maintenance tool (square sides upmost)

as far down as possible over the new sensor spot.

Continue to push down on the tool and turn gently

until the square sides of the tool and the square

slots of the sensor spot engage. The tool should

then drop into position.

2. Make sure the sensor collar is as far down as it will

go, so that the top of the collar is aligned with the

base of the sensor head.

3. Take the combined maintenance tool and sensor

spot and place it in the end of the sensor.
