Working with unfamiliar equipment can lead to careless injuries. Read and understand this manual and
the manual for your vehicle before assembling, installing, operating, or maintaining this earth auger. If
there is anything in this manual you do not understand, contact your dealer or Danuser LLC. The safe use
of this machine is strictly up to you, the operator. If this unit is used, loaned, or rented by any other
person, it is the owner's responsibility to make certain that the operator prior to operating:
• Reads and understands the Operator's Manuals
• Is instructed in safe and proper use
There is an entanglement risk if you replace the special auger retaining bolt with a bolt longer than
specified by Danuser LLC. This improper replacement occurs most often on machines that are loaned or
rented to someone who has not read the Operator's Manual and is not familiar with an earth auger.
• This earth auger is designed for one-man operation from the vehicle seat. It is the responsibility of
the operator to see that no one is within twenty-five feet (25') of the earth auger when it is started or
in use. Do not operate the earth auger with another person near or in contact with any part of the
drive unit or auger. Serious personal injury or death may result if any attempt is made to assist
drilling operation by hand.
• All operators of this equipment must read and understand this entire manual, paying particular
attention to safety messages and operation instructions, prior to assembling, installing, or operating
the earth auger.
• Please remember it is also important that you read, understand, and follow the safety signs on the
earth auger. Clean or replace all safety signs if they cannot be clearly read and understood. They are
there for your safety as well as the safety of others. Danuser LLC will furnish new safety signs upon
request at no charge.
• All things with moving parts are potentially hazardous. There is no substitute for a cautious,
safe-minded operator who recognizes potential hazards and follows reasonable safety practices.
• Personal protection equipment including hard hat, safety glasses, safety shoes, and gloves are
recommended during assembly, installation, operation, maintenance, removal, or movement of the
earth auger.
• When the use of hand tools is required to perform any part of assembly, installation, maintenance,
removal, or movement of the earth auger, be sure the tools used are designed and recommended by
the tool manufacturer for that specific task.
• Never check pressurized system for leaks with your bare hand. Wear proper hand and eye protection
and use wood or cardboard when searching for suspected leaks. Oil escaping from pinhole leaks
under pressure can penetrate skin and create a serious medical emergency. If any fluid is injected into
the skin, gangrene, blood poisoning, even death may result. Obtain medical attention immediately.
• Always use two people to handle heavy, unwieldy components during assembly, installation,
maintenance, removal, or movement of the earth auger.
• Never place any part of your body where it would be in danger if movement should occur during
assembly, installation, operation, maintenance, removal, or movement of the earth auger.
• Check clearances between vehicle and auger, as well as operator and auger, across the full range of
loader arms’ operating heights. Keep earth auger in cradle when not drilling.
• Only properly trained people should operate this equipment. Do not allow anyone who has not read
this entire manual and understood the safety rules, safety signs, and operation instructions to use this
earth auger.
• Never allow children to operate or be around this earth auger.
Safety
WARNING

• Do not allow riders on the equipment at any time. There is no safe place for any riders.
• Never use alcoholic beverages or drugs which can hinder alertness or coordination while operating
this equipment. Consult your doctor about operating this machine while taking prescription
medications.
• Consult local utility companies to make certain there are no buried gas lines, electrical cables, etc.,
in the work area before beginning operation.
• Before beginning operation, clear the work area of objects which might be picked up and thrown by
or entangled in the auger.
• Before you operate the earth auger, check over all pins, bolts, and connections to be sure all are
securely in place. Replace any damaged or worn parts immediately.
• Never replace the auger retaining bolt with anything other than the specified length bolt in this
manual. A longer, or protruding, fastener is more likely to grab clothing or gloves, which can result
in serious injury or death.
• Keep hands, feet, hair, jewelry, and clothing away from all moving and/or rotating parts.
• Never place yourself between the vehicle and the earth auger while the vehicle is running.
• Worn teeth or a slightly rounded point can seriously affect auger penetration. Check for wear before
each use, and replace as necessary.
• Never position the auger point by hand or with any tool when the vehicle is running.
• Never position the auger point by putting your hands on the auger or drive unit.
• Do not shovel dirt away from a rotating auger, as the shovel can be caught and thrown by the auger.
• Never transport with the drive unit out of the cradle or while the auger is rotating.
• Do not walk or work under a raised earth auger unless it is securely blocked or held in position. Do
not depend on the vehicle hydraulic system to hold the earth auger in place.
• A heavy load can cause instability of the vehicle. Use extreme care during travel. Slow down on
turns and watch out for bumps. Use all safety devices, including a seat belt, as recommended in the
vehicle operator’s manual.
• Do not operate the earth auger on steep hillsides. When drilling on uneven or hilly terrain, position
the vehicle with the earth auger uphill. With the earth auger downhill, the vehicle could tip when
attempting to raise the auger from its hole. Consult your vehicle operator’s manual for maximum
incline allowable.
• Always shut off the vehicle engine and remove the key before dismounting the vehicle. Never leave
equipment unattended with the vehicle running.
• 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.
• Most accidents occur because of neglect or carelessness. Keep all helpers and bystanders twenty-five
feet (25') away from an operating earth auger.
• Always use care when operating an earth auger.
Safety is a primary concern in the design, manufacture, sale, and use of earth augers. As the manufacturer
of your earth auger, we want to confirm to you, our customer, our concern for safety.

Filtration Requirements:
• A filter of, at least, 25 micron filtration is required. A filter capable of 10 micron
filtration is preferred. The majority of paper type filters are 25 microns or better.
• A low pressure type filter can be installed in the return line from the control valves to
the sump. A low pressure type filter can, also, be installed in the sump or pump intake
line, but must be sized large enough to avoid starving the pump.
• A high pressure type filter can be used between the pump and the control valves.
• If the source of the hydraulic power does not have a filter, it will be necessary to install
one at some point in the system so, at least, part of the hydraulic oil is being filtered
whenever the system is operating. After a filter is installed and before attaching the
drive unit, the entire hydraulic system should be drained, filled with new oil, and
operated for 30 minutes or until the system is warm. During this run time, operate all
valves, cylinders, and hydraulic motors on the machine.
Pressure and Flow Requirements:
• Models EP6, EP10, and EP15 Danuser Earth Augers are designed to operate within the
pressure range of 1500 to 3000 PSI.
• Operating flow rate is dependent on model: 6 to 15 GPM for Model EP6, 10 to 20
GPM for Model EP10, and 15 to 30 GPM for Model EP15.
Valve Requirements:
• The hydraulic system used to power the drive unit should be equipped with a four-way
valve large enough to carry full pump outlet without restricting flow and causing oil
heating.
• The four-way valve requires a relief valve which will open and relieve extreme
pressures between the drive unit and control valve, even when the control valve is in a
neutral position. This feature can be obtained by connecting two external relief valves
between the main lines running from the control valve to the drive unit in such a way
that high pressure in either line will be relieved to the other line.
Hydraulic Hose Requirements:
• High pressure hoses of, at least, 1/2 inch inside diameter connect four-way valve to the
hydraulic fittings on the top of the drive unit. If the drive unit is mounted 10 feet or
more from the hydraulic outlets on your unit, or the pump delivers 20 GPM or more,
hose size should be increased to 3/4 inch inside diameter.
• Working pressure of hydraulic hoses must be higher than the rated vehicle hydraulic
pressure.
• An abrasion sleeve is recommended on all hydraulic hoses.
• The hydraulic hoses should be equipped with a 45-degree fitting on the drive unit end.
• The hydraulic fittings on the top of the drive unit are #10 JIC male.
• Since the motor is reversible, hose connections to motor fittings are interchangeable.
• All hoses, pipes, and fittings used to connect the drive unit should be thoroughly
cleaned before use. Care should be taken to see that no thread sealer or metal chips are
forced to the inside of the joints when connections are being tightened.
Hydraulic Fluid Selection Requirements:
• Premium grade petroleum based fluids will provide the best performance.
• A hydraulic fluid that contains anti-wear agents, rust inhibitors, anti-foaming agents,
and oxidation inhibitors is recommended.
• The viscosity of the fluid should never fall below 70 SUS (13 cST). The best
viscosity range of the drive unit is 100-200 SUS (20-43 cST). 7
Hydraulic
Requirements
The life of the hydraulic motor is almost entirely dependent upon cleanliness of
the oil. Instructions in your vehicle operator’s manual regarding filter and oil
changes should be carefully followed. Even small amounts of dirt in the
hydraulic oil can cause premature motor failure that is not covered by warranty.

STEP 5: Grease the inside of the auger collar liberally and attach the auger with the
retaining bolt and nut that came attached to the drive unit spindle. This is a
special thread length bolt - use genuine Danuser replacement parts only. For
hex spindle, use Danuser PN 10038 (3/4” 10 x 4”, Gr. 8, 3/4” of thread) special
retaining bolt and nut PN 10041. NEVER use a bolt longer than longer than 4".
For round spindle, use Danuser PN 10039 (7/8” 9 x 4-1/4”, Gr. 8, 3/4” of thread)
special retaining bolt and nut PN 10042. NEVER use a bolt longer than longer
than 4-1/4”.
STEP 6: The hydraulic fittings on the top of the drive unit are #10 JIC male. Install 1/2”
Danuser Hose Kit if your unit delivers less than 20 GPM. Install 3/4” Danuser
Hose Kit if your unit delivers 20 GPM or more. Danuser Hose Kits include
abrasion sleeves. Since the motor is reversible, hose connections to motor fittings
are interchangeable.
STEP 7: If you did not purchase quick couplers with your unit, you must obtain and install
the proper hydraulic quick couplers for your particular vehicle.
STEP 8: After you have tightened the drive unit connections, run the hoses through the
hose holder on the quick attach plate and plug them into your auxiliary hydraulic
outlets.
STEP 9: Test the vehicle to make sure you have enough hose length to perform the full
range of the loader arms’ operating heights.
Remember hydraulic systems are under pressure whenever
the engine is running and may hold pressure after shutdown.
Before connecting or disconnecting hydraulic hoses, be sure
to relieve all pressure by cycling all hydraulic controls after
shutdown.
Never check pressurized system for leaks with your bare
hand. Wear proper hand and eye protection and use wood or
cardboard when searching for suspected leaks. Oil escaping
from pinhole leaks under pressure can penetrate skin and
create a serious medical emergency. If any fluid is injected
into the skin, gangrene, blood poisoning, even death may
result. Obtain medical attention immediately.

WARNING
WARNING
Each time an auger or extension is attached to the drive unit, the inside of the
collar should be coated liberally with grease.
NOTE
All hoses and fittings used to connect the earth auger should be thoroughly
cleaned before use. Care should be taken to see that no thread sealer or metal
chips are forced to the inside of the joints when connections are being tightened.
NOTE
Fittings must be compatible with the fittings on your vehicle. Be sure the threads
match on the hydraulic quick couplers you are using.
NOTE
The hydraulic hoses should be equipped with a 45-degree fitting on the drive unit
end.
NOTE

Operation
STEP 1: Contact local utility companies to make certain there are no buried gas lines,
electrical cables, etc., in the work area. Clear area of objects that could wrap
around the auger or might be thrown. Check for ditches, stumps, holes, or other
obstacles that could cause the vehicle to roll.
STEP 2: Layout and mark where you want to drill your holes.
STEP 3: Lower the auger point slowly to the ground with the auger not powered.
STEP 4: With the auger point lowered to the ground and before engaging the auger, move
the vehicle slowly left, right, forward, or backward as needed until the auger
appears vertical to the ground.
STEP 5: Actuate the hydraulics to start the auger’s rotation in the clockwise direction and
increase the speed as required so dirt is conveyed from the hole.
This earth auger was designed for one-man operation from the
vehicle seat. It is the responsibility of the operator to see that
bystanders and all other people are at least twenty-five feet
(25') from the earth auger in operation or under power.
Serious personal injury or death may result if any attempt is
made to assist earth auger operation by hand.
Read and understand this Operator’s Manual carefully before attempting to operate the
Danuser Earth Auger. You are responsible for furnishing this manual to others who may use
the unit. If you have any questions regarding the proper assembly, installation, or operation
of this earth auger, contact your dealer or Danuser LLC.
Serious injury or death
can result from misuse of
this equipment.
Personal protection
equipment including hard
hat, safety glasses, safety
shoes, and gloves are
recommended during
assembly, installation,
operation, maintenance,
removal, or movement of
the earth auger. Do not
allow long hair, loose
fitting clothing, or jewelry
to be around moving
parts.
Differences in diameter and length of auger when combined
with various heights of loader arms can allow the auger to
come into contact with skid-steer or operator when earth
auger is outside of cradle.
Before operating, check clearances between skid-steer and
auger, as well as operator and auger, across the full range of
loader arms’ operating heights.
Keep earth auger in cradle when not drilling.
To reduce the risk of personal injury, never transport with the
drive unit out of the cradle or while the auger is rotating.
Never position the auger point by hand or with any tool when
the vehicle is running. Never position the auger point by
putting your hands on the auger or the drive unit.

Skid-steer mounted earth augers should not come in contact with the cradle during
drilling maneuvers. Drill with the quick attach plate in the horizontal position.
NOTE
The hydraulic actuation lever connected to the earth auger will have three
positions: clockwise rotation, stop (neutral), and counter-clockwise rotation. The
clockwise and counter-clockwise positions may be changed by switching the hose
connections.
NOTE

Operation
(continued)
STEP 6: The hydraulic flow rate or pressure should not exceed the earth auger’s specified
maximums. The hydraulic minimums must be met to deliver satisfactory
performance. Use only enough down pressure to assure positive penetration of
the 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
frequently stall. See Hydraulic Requirements section for filtration, pressure, and
flow rate specifications.
STEP 7: When the auger has been lowered about 24 inches into the ground, raise the auger
almost out of the hole to clear the dirt, then drill deeper and raise the auger again.
Repeat this procedure until the desired hole depth is reached.
STEP 8: When the auger has reached the full depth required, allow the auger to dwell
momentarily at this depth at a slower speed to assist in cleaning out the hole.
STEP 9: Deactivate the earth auger, and raise it from the hole.
STEP 10: Move away from the hole, then remove loose dirt from the auger by momentarily
actuating the earth auger and spinning it at a faster speed than used for drilling.
STEP 11: If necessary, repeat STEPS 8 and 9 to obtain a cleaner hole.
Replacement of the retaining bolt should be as follows:
a) Shut off the vehicle engine, and remove the vehicle key.
b) Install a new Danuser retaining bolt. This is a special thread length bolt -
use genuine Danuser replacement parts only. For hex spindle, use Danuser
PN 10038 (3/4” 10 x 4”, Gr. 8, 3/4” of thread) special retaining bolt and nut
PN 10041. NEVER use a bolt longer than 4”. For round spindle, use
Danuser PN 10039 (7/8” 9 x 4-1/4”, Gr. 8, 3/4” of thread) special retaining
bolt and nut PN 10042. NEVER use a bolt longer than 4-1/4”.
c) Tighten the retaining bolt and nut securely.
STEP 12: Deactivate the auger and place the drive unit in the cradle when moving between
holes.
The earth auger should be raised and lowered by changing the elevation and not
the tilt of the quick attach plate.
Do not shovel dirt away
from a rotating auger, as
the shovel can be caught
and thrown by the auger.
To prevent injury, keep an
area of at least twenty-five
feet (25’) around the auger
clear of bystanders and all
other people.
For “heavy” soil conditions, allow the auger to turn at slow speed while raising it
to the top of the hole.
Replace a broken,
damaged, or missing
auger retaining bolt ONLY
with an authorized factory
replacement. An auger
retaining bolt that is too
long increases the
possibility of personal
injury. The auger
retaining bolt must be of
the proper size and grade
to function properly.

WARNING
NOTE
NOTE
NOTE
If you have difficulty penetrating hard ground, refer to the Troubleshooting
section.
NOTE
Frequently check the condition of the auger teeth and point, and replace them
when wear is detected. Always keep spare parts on hand for replacements to
avoid damage to the auger head and auger flighting.
NOTE
Since the earth auger uses a Grade 8 retaining bolt, all vehicles must be protected
with relief valves or some other means of protection against excessive pressures.
Failure of the retaining bolt is a possible indication of excessive pressure.
NOTE
If the auger becomes lodged under rocks, roots, or other large obstructions, do
not attempt to pull the auger out of the ground. If this happens, reverse the auger
rotation (counter-clockwise), and slowly raise the auger. Once unstuck, continue
operation.
NOTE
In some soil conditions, or when excessive down pressure is applied, the auger
may screw itself into the ground and become stuck, causing the earth auger to
stall. Do not attempt to pull the auger out of the ground. Instead, reverse the
auger rotation (counter-clockwise), and slowly raise the auger. Once unstuck,
continue operation.

CHECK PLANETARY GEAR OIL LEVEL
Check oil level daily to assure proper lubrication is maintained. Check by removing the
front fill plug - with the drive unit angled approximately 30 degrees from vertical.
CHECK FOR CLEAN HYDRAULIC OIL
The majority of all hydraulic component failures are caused by contamination of the
hydraulic oil. At all times, keep dirt and other contaminates from entering the hydraulic
system during connecting and disconnecting the hydraulic system. Always use dust caps
and plugs on all quick disconnects when not in use.
CHECK ALL HYDRAULIC HOSE ASSEMBLIES
Check for cracked or brittle hoses. Replace hoses immediately if cracked or brittle.
Replacement of hoses before failure will prevent loss of hydraulic oil, hydraulic oil
contamination, and component damage caused by cavitation.
CHECK DRIVE UNIT AND ALL ACCESSORIES
Check for loose, bent, cracked, or worn bolts and fasteners. Check drive unit output spindle
for bends, cracks, breaks, or wear. Replace the bolts, fasteners, or output spindle if any of
these conditions exist.
CHECK AUGER
Check for loose or worn cutting teeth and point. Worn teeth or point can dramatically affect
auger penetration and greatly reduce the life of the auger. Always keep spare teeth and
points on hand. Liberally coat the auger with grease once the paint is removed to prevent
rusting.
CHECK ALL CONNECTING PINS
Check for bends, cracks, breaks, or wear. Replace if any of these conditions exist.
COAT THE INSIDE DIAMETER OF THE AUGER OR EXTENSION COLLAR
To prevent rust and reduce wear, liberally coat with grease the inside diameter of the auger
and extension collars each time they are attached.
CHANGE OIL
Change planetary gear reduction oil after first 500 hours of operation or 6 months, then
every 2000 hours or 12 months, whichever comes first. Use heavy duty extreme pressure
lubricant API-GL-5 85W-140 for filling the planetary gear reduction. Approximate oil
capacity is .90 quarts (.85 liters).
Maintenance DAILY
EACH TIME AN AUGER OR EXTENSION IS ATTACHED
AFTER 1ST 500 HOURS, THEN EVERY 2000 HOURS OR YEARLY
