SAFETY INFORMATION
THE USE OF THIS EQUIPMENT IS SUBJECT TO CERTAIN HAZARDS WHICH CANNOT BE
PROTECTED AGAINST MECHANICAL MEANS OR PRODUCT DESIGN. ALL OPERATORS
OF THIS EQUIPMENT MUST READ AND UNDERSTAND THIS ENTIRE MANUAL, PAYING
PARTICULAR ATTENTION TO SAFETY AND OPERATING INSTRUCTIONS, PRIOR TO
USING THE EA AUGER. IF THERE IS SOMETHING IN THIS MANUAL YOU DO NOT
UNDERSTAND, ASK YOUR SUPERVISOR TO EXPLAIN IT TO YOU. FAILURE TO OBSERVE
THESE SAFETY PRECAUTIONS CAN RESULT IN DEATH OR SERIOUS INJURY OR SERI-
OUS EQUIPMENT DAMAGE.
All bystanders should be kept a minimum of 10 feet away from working area of the earth
auger.
Always wear an OSHA approved hard hat and safety eye protection when operating or
servicing this equipment. Do not wear loose fitting clothing, flopping cuffs, dangling
neckties and scarves, or rings and wrist watches that can catch moving parts.
An operator must not use drugs or alcohol, which can alter his alertness or coordination.
An operator taking prescription or over the counter drugs should seek medical advice on
whether or not he can safely operate equipment.
Always locate underground electrical wires, telephone cables, and gas, water, and
sewer lines before digging. Maintain safe clearance and avoid contact with any under-
ground or overhead utility lines or electrically charged conductors.
Never alter or remove any safety decals or safety shields. Check this manual for loca-
tion of these items and replace immediately if damaged or illegible.
Never adjust a relief valve for pressure higher than recommended by vehicle manufacturer.
Whenever changing or installing this or other attachments, make sure all connections
are securely fastened.
Travel only with the earth auger in a safe transport position to prevent uncontrolled
movement. Drive slowly over rough ground and on slopes. Tether earth auger with a
chain, if necessary, to prevent uncontrolled swinging of earth auger when moving from
hole to hole. Remove earth auger from vehicle when transporting to and from job site.
Before exiting the vehicle, lower earth auger to ground, turn off vehicle engine and lock
vehicle breaks.

Never check a pressurized system for leaks with your bare hand. Oil escaping from
pinhole leaks under pressure can penetrate skin and could cause serious infection.
Hold a piece of cardboard up next to suspected leaks and wear a face shield or safety
eye protection. If any fluid is injected into the skin, it must be removed immediately by a
doctor familiar with this type of injury.
Before disconnecting hydraulic lines or fittings be sure to relieve all pressure by cycling
all hydraulic controls after shutdown. Remember hydraulic systems are under pressure
whenever the engine is running and may hold pressure after shutdown. Before applying
pressure to the system make sure all connections are tight and that there is no damage
to lines, fittings, and hoses.
Flow and pressure gauges, fitting, and hoses must have a continuous operating pres-
sure rating of at least 25% higher than highest pressures of the system.
Avoid steep hillside operation, which could cause the vehicle to overturn. Consult your
vehicle operator’s and safety manuals for the maximum incline allowable.
Never perform any work on an earth auger unless you are authorized and qualified to
do so. Always read the operator service manual before any repair is made. After com-
pleting maintenance or repair, check for correct functioning of the earth auger. If not
functioning properly always tag “DO NOT OPERATE” until all problems are corrected.
This manual covers the safe use, installation, operation, and service instructions for the
earth auger only. Always read the operating and safety manuals prepared for your vehi-
cle and any other attachments before using them.

HYDRAULIC SYSTEM HOOK-UP INSTRUCTIONS
1. Once the installation instructions are complete you are now ready to make the hydraulic con-
nections necessary to operate your earth drill. Read and understand safety information
prior to making hydraulic connections.
2. Your equipment dealer is in the best position to advise you as to where the best place on your
machine is to make the hydraulic connections to power your earth drill drive unit. Some of the
most common places to “tap” into the hydraulic system on various types of machines are as
follows:
Skid Steer Loaders ..............Auxiliary Hydraulic Outlets.
Backhoes & Excavators ......Auxiliary Hydraulic Outlets or Bucket Curl Cylinder Outlet.
Wheel Loaders ......................Auxiliary Hydraulic Outlets or Bucket Dump Cylinder Circuit.
3. Determine the length of hydraulic hoses required to plumb drive unit into the place on your
machine where you will be “tapping” in to the hydraulics. Be sure the two hydraulic hoses are
long enough to perform at the full range of the earth drills’ operating capacity.
4. Models EA10, EA15, and EA19 require two ½” I.D. hoses with #10 JIC female fittings on one
end of each to connect hoses to drive unit fittings.
5. Once all hydraulic connections have been made and checked for leaks and proper hose
lengths, you are now ready to operate your earth drill. Read and understand operating
instructions and safety information prior to operating your earth drill.
WARNING! Hoses and Fittings must have a Continuous Operating Pressure
Rating of at least 25% Higher than the Highest Pressures of the System that you
are “tapping” into.

1. After all installation instructions have been completed, safety information read and understood and the
rest of this operator’s manual has been reviewed, your Hydraulic Earth Drill is now ready to use.
2. With the auger raised off the ground and the vehicle engine set at a low RPM, activate the earth drill
control valve to determine position control valve lever must be in to turn auger in a forward (clockwise)
rotation. This is the “digging” position.
3. Before beginning to dig, experiment with auger speed to determine a suitable auger RPM. Generally
in light and sandy soil a high RPM is desirable. In hard, rocky, or frozen soils a slower RPM is desir-
able. To increase auger RPM, increase vehicle engine RPM. To decrease auger RPM, decrease
vehicle engine RPM.
4. Return earth drill control valve to neutral position to stop the auger. Lower the auger to the ground so
that only the center point penetrates the ground about 2”.
5. Activate the earth control valve so auger is turning in a forward (clockwise) rotation. Use only enough
down pressure to assure positive penetration of auger into the ground. Ease up on down pressure if
auger rotation slows down drastically or stalls. Excessive down pressure will cause the auger to stall
frequently.
6. When the auger has penetrated the ground about 24”, raise the auger from the hole to clean the dirt
out. Repeat this procedure until the desired hole depth is obtained.
7. Once the required hole depth is reached, allow the auger to turn a few seconds at this depth to clean
the hole.
8. Return the earth drill control valve to the neutral position to stop the rotation of the auger. Raise the
auger out of the hole, move away from the hole, then activate the earth drill control valve to spin the
loose soil off of the augers.
9. If necessary, repeat steps 7 & 8 to obtain a cleaner hole.
10. In some soil conditions or when excessive down pressure is applied, auger may “screw” itself into the
ground and become stuck causing earth drill to stall. If this happens, reverse the auger rotation
(counter Clockwise) by moving the control valve lever to the reverse position and slowly raise the
auger. Once the auger is unstuck, return the control valve lever to the forward position and continue
digging.
11. If the auger becomes lodged under rocks, roots, or other large obstructions, do not attempt to raise
auger out of the ground. See step 10 for proper procedure to relieve the auger.
12. Avoid excessive side loading to the earth drill which can cause drive unit or auger damage.
13. Keep auger teeth and points in good condition. Check frequently and always keep spares on hand so
they can be replaced as wear is detected to avoid damage to tooth holders and auger flighting.

MAINTENANCE INSTRUCTIONS
1. CLEAN HYDRAULIC OIL IS ESSENTIAL! 80% of all hydraulic component failures are caused by con-
tamination of the hydraulic oil. Always keep all dirt and other contaminates from entering hydraulic sys-
tem during disconnect and connect operations. Always use dust caps and plugs on all quick disconnects
when not in use. Tightly cap all hydraulic openings to hold oil in and keep dirt and other contaminates
from entering hydraulic systems.
2. CHECK ALL HYDRAULIC OIL DAILY FOR CONTAMINATION. If contamination is present, determine
the source of the problem.
3. INSPECT ALL HYDRAULIC HOSE ASSEMBLIES DAILY for cracked and brittle covers caused by
excessive heat. Reduced viscosity of hydraulic oil occurs at higher operating temperatures and causes
a breakdown of fluid additives such as wear inhibitors. Excessive heat will cause higher internal leak-
age in drive unit motor to become brittle and crack. Replacement of hoses before failure will prevent
loss of hydraulic oil, time consuming “bleeding” of system, hydraulic oil contamination, and component
damage caused by cavitations. It will also reduce the chance of personal injury caused by hydraulic fluid.
4. CHECK AUGER DAILY for loose, worn or broken cutting teeth and point. Worn teeth or point can dras-
tically affect auger penetration and greatly reduce auger life expectancy. Always keep spare teeth and
points on hand. Some digging conditions may require checking teeth and point at more frequent inter-
vals.
5. CHECK DRIVE UNIT AND ALL ACCESSORIES DAILY for loose, bent, cracked, or worn, bolts and fas-
teners. Always use grade 5 or better replacement bolts. Always use lock washers with standard hex
nuts or self locking nuts.
6. CHECK ALL CONNECTING PINS DAILY for bends, cracks, breaks, or wear. Replace if any of these
conditions exist.
7. CHECK DRIVE UNIT OUTPUT SHAFT DAILY for bends, cracks, breaks, or wear. Replace if any of
these conditions exist.
8. CHANGE PLANETARY GEAR REDUCTION OIL AFTER FIRST 50 HOURS OF OPERATION, THEN
EVERY 1000 HOURS OR IN ONE YEAR, WHICHEVER COMES FIRST. Use mild extreme pressure
lubricant API-GL-5 number 80 or 90 for filling planetary gear reduction under normal temperature ranges
between 0 degrees and 120 degrees. Approximate oil capacity for models EA10, EA15PD, and EA19 is
two pints. Check oil level daily to assure proper lubrication is maintained.
9. When storing Drive Unit for any length of time be sure Drive Unit motor and hoses are full of clean oil.
Also, be sure that Planetary Gear Reduction is full to the recommended capacity for each model as out-
lined in number 8 above.
10. Drive Unit output shaft, inside of Auger Collar, Variable Auger Extension shaft, inside of Variable Auger
Extension Collar and all Connecting Pins should be coated liberally with grease as required to prevent
rust and reduce wear.
11. Once paint has been worn off auger, coat liberally with grease as required, to prevent rusting.
12. Check Planetary Gear oil as follows. Lie Drive Unit horizontal with ground, place bottom drain plug
straight up. Remove plug, tilt drive unit at 2:00 or 10:00. Fill until oil leaks out from hole at one of these
positions.

DISASSEMBLY:
Cleanliness is extremely important when
repairing a hydraulic motor. Work in a clean
area. Before disconnecting the lines, clean
the port area of the motor thoroughly. Use a
wire brush to remove foreign material and
debris from and around the exterior joints of
the motor. Check the shaft and keyslot and
remove all nicks, burrs or sharp edges that
might damage the bearing housing seals
when installing the shaft and the bearing
assembly. Before starting the disassembly
procedures, drain the oil from inside the
motor.
1. Place the motor in a vise with the output shaft
down (Fig.1). Clamp across the mounting flange
of the motor, not the housing. Excessive clamp-
ing pressure will cause distortion. When clamping
use some protective device on the vise, such as
special soft jaws, pieces of hard rubber, or board.
