DANGER
If the Zap-Alert system activates while drilling, the
machine, except for the operator's platform, will
become energized. If you step off the operator
platform or if someone touches the machine or wet
ground near the machine or in the bore, you or
they could be electrocuted causing serious injury
or death.
• Test the Zap-Alert system before drilling.
• Deploy the grounding stake before drilling.
Ensure that the stake is fully inserted into moist
soil.
• If the Zap-Alert is triggered:
– Stay in the seat and do not touch the ground
or any other part of the machine until the
power has been turned off. Do not pour
liquids or urinate from the operator platform
onto the ground.
– Stop drilling, stop the drilling-fluid flow, and
retract the drill out of the ground.
– Keep everyone away from the machine,
wet ground near the machine or running
from the machine, and any open sources of
water/mud that is in the bore and contacting
the broken line.
– Contact the utility company to have power
shut off to the broken line. Do not reset the
Zap-Alert system until the power has been
turned off.
1. Remove the grounding stake from the holder on the
side of the operator platform

3. If the ground is dry where you put the stake, soak it
with water before using the machine to ensure good
electrical contact.
