Checking the Pipe Load Guard
Safety Interlock Functions
You will need 2 people for this procedure.
1.
Start the engine.
2.
Lower the pipe load guard.
3.
With the engine running, have 1 person sit in the
seat and begin the drilling process.
4.
Raise the pipe load guard.
Note:
The cam assembly should not engage.
If it does engage, there is a malfunction in the
interlock system that you should correct before
resuming operation.
Testing the Zap-Alert
System
DANGER
If the Zap-Alert system activates while drilling,
the machine will become energized. If you
step off of 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.
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 becomes
energized, setting off the alarm.
Test the Zap-Alert system before using the drill each
day, as follows:
1.
Remove the ground cable from its storage
position at the rear of the machine
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.
Open the front hood; refer to
and Rear Hoods (page
4.
Connect an alligator clip from the Zap-Alert
tester to the grounding stud on the Zap-Alert
system
(Figure 46
5.
Connect the other alligator clip to a metal
component of the machine frame.
6.
Push the T
EST
