Setting up the Pump to Use a Natural Water Source
To set up a pump to use a natural water source, you must
ensure that you use the Y-screen to filter all materials other
than water.
1.
Remove the pump-inlet cap (
).

Deploying the Zap-alert System
The Zap-alert system is an electric strike-sensing device
on the machine that triggers a strobe light and an audible
alarm whenever 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. The
operator’s platform is electrically isolated from the rest of
the machine to protect you.
DANGER
If the Zap-alert system activates while drilling, the
machine, except for the operator 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 the one who touched the machine 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 the
power shut off to the broken line. Do not
reset the Zap-alert system until the power
has been turned off.
