Zero switch (for customers with the Halo magnetic battery)
The battery is equipped with a zero function which zero’s out the inclination. This can be useful if drilling on an incline that is
not plumb, such as inclined piers. It’s also useful if a greater accuracy is required. A colour sequence displays on the Halo
LED ring to give the operator an indication of zero mode. Press the switch to activate zero mode and the Halo LEDs will
all ash blue for a moment. When in zero mode, the middle section of the LED array will illuminate blue. To exit zero mode,
press the switch again and the LEDs will all ash white for a moment. Now the middle section of the LED array will display
white. It’s not recommended to zero the Halo beyond 30° from plumb. The zero switch is of a type which has no mechanical
movement. This
improves the longevity and reliability of the switch. The lack of noticeable movement does not indicate a fault. To activate
the switch, tap and press heavily on the top of the switch and observe the LED changes.
Charging the battery
The battery should be charged after every use and at least once every 3 months if not used regularly. This type of lithium
battery will have a prolonged life if charged after or before each use. Make sure the battery is never left hanging by the
charger cord as this could result in failure over time. The charger should only be used indoors and out of direct sunlight in a
cool, dry place (similar to where and how you would charge a mobile phone). The battery should be charged fully before rst
use. Batteries are shipped at 30% charge as per recommended practise.
Best practices
When connecting power to the Halo, allow the drive to hang stationary (no movement) for 30 seconds for the system to
perform a start-up calibration. If this isn’t permitted, the calibration may not complete.
While HALO is not in use, while being transported or stored, place the yellow lead-in cable into the hood to protect it from
potential crushing damage. Ensure cable is connected to the hood or hoses before placing into the hood to avoid cable
from falling out of reach.
