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 attachment must read and understand this entire manual, paying particular
attention to safety messages and operation instructions, prior to assembling, installing, operating,
maintaining, servicing, removing, or moving the earth auger.
• Please remember it is also important that you read, understand, and follow the safety signs on the
attachment. 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, service, removal, or movement
of the attachment.
• When the use of hand tools is required to perform any part of assembly, installation, maintenance,
service, 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, service, removal, or movement of the attachment.
• Never place any part of your body where it would be in danger if movement should occur during

• The earth auger must be securely latched to the vehicle. Ensure quick attach latching method is
properly secured. An improperly latched earth auger can fall without warning.
• Before you operate the attachment, 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 all helpers and bystanders twenty-five feet (25') away from an operating earth auger.
• Keep hands, feet, hair, jewelry, and clothing away from all moving and/or rotating parts.
• Never place yourself between the vehicle and the attachment.
• 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 exceed the vehicle’s rated operating load. Use sufficient counterweights. Move the vehicle
slowly when the attachment is raised.
• 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, remove the key, lower vehicle arms, and relieve all hydraulic
pressure before dismounting the vehicle. Never leave equipment unattended with the vehicle
running.

• Never attempt adjustments, service, or repairs while the equipment is in operation.
• Never work under equipment supported by hydraulics. Even with the vehicle shut off, equipment can
suddenly drop if controls are actuated or if hydraulic lines burst.
• 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.
• Store the attachment on a flat, level surface in an area where children do not play. Securely block
and support the attachment.
• Do not modify the attachment. Modifications may weaken the integrity of the attachment and may
impair the safety, function, life, and performance of the earth auger.
• When making repairs or servicing the earth auger, use only parts that meet original equipment
manufacturer's standards and requirements.
• Always use care when operating the earth auger. Most accidents occur because of neglect or
carelessness.

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 EP615, EP1020, EP1530, and EP2035 Danuser Earth Augers are designed to
operate within the pressure range of 1500 to 3500 PSI.
• Operating flow rate is dependent on model: 6 to 15 GPM for Model EP615, 10 to 20
GPM for Model EP1020, 15 to 30 GPM for Model EP1530, and 20 to 35 GPM for
Model EP2035.
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" inside diameter connect four-way valve to the
hydraulic fittings on the top of the drive unit.
• Working pressure of hydraulic hoses must be higher than the rated vehicle hydraulic pressure.
• An abrasion sleeve is recommended on all hydraulic hoses.
• The drive unit is equipped with two 45° adapters to which hoses can be connected. These
adapters are #10 JIC M.
• Since the motor is reversible, hose connections to motor fittings are interchangeable.
• All hoses, pipes, adapters, 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.
• Fluids that contains anti-wear agents, rust inhibitors, anti-foaming agents, and oxidation
inhibitors are recommended.
• The viscosity of the fluid should never fall below 70 SUS (13 cST). The best
viscosity range for the drive unit is 100-200 SUS (20-43 cST).
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.
NOTE
For vehicles delivering higher than 3500 PSI, a cross port relief valve is available.
Refer to Accessories section.

Additional factors that influence clearance between cradle and drive unit include:
• Length of auger
• Maximum tilt angle of vehicle
• Angle of hole being drilled
• Slope of ground
The cradle mounting bolt holes closer to
the drive unit set the carry angle at 15°.
The bolt holes further from the drive unit
set the carry angle at 30°.
It is recommended to install the cradle in the 15° carry angle, provided the cradle
does not come into contact with the drive unit housing during drilling operations.
Damage may occur if the cradle comes into contact with the drive unit housing
during drilling operations.

If you purchased Danuser Hose Kits PN 196025 or PN 196027, install by using a
7/8" wrench and a 1" wrench to tighten the hose connections onto the 45° adapters
on the drive unit.
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.
Since the hydraulic motor is reversible, hose connections to motor fittings are
interchangeable.
Using a 1-7/16" wrench and a 1" wrench, tighten the hydraulic quick couplers onto
the hoses.
Danuser Hose Kit PN 196025 does not include hydraulic quick couplers. You
must obtain the proper hydraulic quick couplers for your particular vehicle.
Install the hose holder spring kit in the desired mounting location. The quick attach
mount uses a hose holder spring kit to allow adjustment of hose routing, reducing
pinching, kinking, and stretching. The hose holder spring kit may be mounted left
or right of center on the quick attach plate. For center cradle installations, it is
recommended to install the hose holder spring kit in the mounting position nearest
the vehicle's hydraulic valve block. For offset cradle installations, the desired spring
mounting location will vary based on the location of the vehicle's hydraulic valve
block. The vehicle loader arm and operator step configuration also may affect the

Hose Routing
If you purchased Danuser Hose Kits PN 196025, 196027, 206031, or 206032,
install by using a 7/8" wrench and a 1" wrench to tighten the hose connections
onto the 45° adapters on the drive unit.
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.
Since the hydraulic motor is reversible, hose connections to motor fittings are
interchangeable.
Using a 1-7/16" wrench and a 1" wrench, tighten the hydraulic quick couplers onto
the hoses.
Danuser Hose Kits PN 206031 and 196025 do not include hydraulic quick
couplers. You must obtain the proper hydraulic quick couplers for your particular

obstacles that could cause the vehicle to roll.
Lay out and mark where you want to drill your holes.
Lower the auger point slowly to the ground with the auger not powered.
For mounts including a cradle, the drive unit should not come into contact with the
cradle during drilling maneuvers. While drilling, maintain the quick attach plate in
a position as close to horizontal as possible. If cradle does come into contact with
drive unit, refer to Assembly & Installation section to adjust carry angle.
With the auger point lowered to the ground and before actuating the auger, move
the vehicle slowly left, right, forward, or backward as needed until the auger
appears vertical to the ground.
Engage the auxiliary hydraulics to start the auger’s rotation in the clockwise
direction and increase the speed as required so dirt is conveyed from the hole.
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.
This earth auger is
designed for one-man
operation from the
vehicle seat. It is the
responsibility of the
