HYDRA-BORER OPERATION
Before You Operate Hydra-Borer
IMPORTANT:
Before beginning any underground
operations, always check with appropriate local utility
companies to determine if any underground cables, wires,
pipes, etc. may be encountered during operations.
Before boring operations begin, do the following:
1. Locate and dig a target hole. This hole should be
large enough for a man to work in [approximately 1.8
x .61 x 1.2m (6 x 2 x 4 ft)].
2. Dig a trench (starting hole) to a depth slightly deeper
than the depth at which boring operations will begin.
The starting hole should be approximately two or
three times the length of the drill stems being used.
3. Place the two guide anchors approximately 1.5 x
2.4m (5 to 8 feet) apart in the starting hole near to
the point at which boring operations will begin. Place
a guide anchor tube over each anchor. The guide ring
on each tube should face away from the wall of the
starting hole. Make sure that the guide anchors are
firmly secured in the ground so that they will not
move or collapse during operation.

4. Align the guide anchors in the direction of the boring
path between starting hole and target hole. The
handle of the drill stem level assembly (see item 11
below) or a string may be used to align the guide
anchors with the boring path.
WARNING:
CLEAR THE WORK AREA OF ALL
BY-STANDERS. DURING HYDRA-BORER
OPERATIIONS KEEP SPECTATORS AWAY. Rock
and soil debris can be thrown a considerable
distance.
WARNING:
Avoid exposure to dust containing
crystalline silica particles. This dust can cause
serious injury to the lungs (silicosis).
WARNING:
Make sure all people are clear of the
machine and working area during Hydra-borer
operations. Serious injury or death can result
from contact with the rotating parts of the Hydra-
borer or flying debris.
WARNING:
Vibrations from the Hydra-borer can
cause a trench, overhang or high bank to fall and
cause injury or death. Be careful when working
near the side of a trench. Serious injury or death
can result if the walls of the trench fall.
WARNING:
Make sure all people are clear of the
work area during Hydra-borer operations. Serious
injury or death can result from contact with the
rotating parts of the Hydra-borer.
WARNING:
Rotating parts - keep clear of
hazardous area. KEEP CLEAR. Serious injury or
death can result from bodily contact.
WARNING:
Never allow anyone in the trench
while during Hydra-borer operations. If work must
be done in the trench or the target hole, always
stop the Hydra-borer and stop the engine.
WARNING:
Do not hold or stand on the drill
stem during Hydra-borer operation. Personal
Injury or death can result. If the drill stem breaks
or needs adjustment, stop the machine, turn off
the engine and remove the key.
