1.5 Magnet Replacement
The magnet in the cap assembly is coated to protect
the magnet from moisture. If the coating becomes
chipped or damaged, the magnet may swell or come
apart. If the magnet is damaged, it can be replaced
by unscrewing one hex screw, removing the old
magnet and replacing it with a new magnet (Figures
7.8 and Figure 7.9).

1.6 Proper Electrical Switch Adjustment
The gap between the electrical switch and the rocker
arm on the flag assembly used with the electrical
indicator comes pre-set from the factory. However,
on occasion the gap may move out of adjustment and
need to be re-adjusted to function properly.
⚠ WARNING
This is a strong magnet. To avoid
personal injury, take care to keep
flesh from between magnet and
metallic items.
