Safety

WARNING

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.

4

• 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

(continued)

• 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.

NOTE

Requirements

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:

• Model EP20 Danuser Earth Augers are designed to operate within the pressure range of
1500 to 3000 PSI.

• Operating flow rate is 20 to 35 GPM.

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 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.

• 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).
