Testing the Zap-Alert System
The Zap-Alert system is an electric strike sensing device on
the machine that triggers a strobe light and audible alarm in
the event that the drill bit, reamer, or stake breaks into an
energized power line. In the event of an electric strike, the
machine will become energized, setting off the alarm.
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.
– Keep standing or running water and drilling
fluid contained close to the machine. Keep
water and drilling fluid sources away from
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.
Test the Zap-Alert system before using the drill each day, as
follows:
1. Open the front hood.
2. Lay the grounding stake flat on the ground away from
the machine. Do not drive the stake into the ground.
Important: Do not allow the stake to touch any
part of the machine.
3. Connect an alligator clip from the Zap-Alert tester to
the grounding stud on the Zap-Alert system
