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,
maintaining, servicing, removing, or moving this Hammer. If there is anything in this
manual you do not understand, contact your dealer or Danuser LLC. The safe use of this
attachment is strictly up to you, the operator. If this attachment 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

• The Hammer is designed to be operated from the vehicle seat. Keep bystanders away
from the work area. Do not operate with another person in contact with any part of the
Hammer.

• 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 Hammer.

• Please remember it is also important that you read, understand, and follow 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, gloves,
and ear plugs 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,
operation, maintenance, or service of the attachment, 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 Hammer.

• Never place any part of your body where it would be in danger if movement should
occur during assembly, installation, operation, maintenance, service, removal, or
movement of the Hammer.

• Only properly trained people should operate this equipment. Do not allow anyone who
has not read this entire manual and understands the safety rules, safety signs, and
operation instructions to use this attachment.

• Never allow children to operate or be around the Hammer.

• Do not allow riders on the equipment at any time. There is no safe place for any riders.

Safety

(continued)

• Never use alcoholic beverages or drugs which can hinder alertness or coordination
while operating this equipment. Consult your doctor about operating this equipment
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.

• Do not drive posts near underground utility lines.

• Stay away from power lines when transporting, raising, or operating the Hammer.

• Before you operate the attachment, check over pins and connections to be sure all are
securely in place. Make sure the Hammer is securely latched to the vehicle.

• Keep hands, feet, hair, jewelry, and clothing away from all moving and/or rotating parts.

• Never place yourself between the vehicle and the attachment.

• Never allow anyone under the attachment at any time.

• Keep clear of the Hammer while in operation. Never position, align, or support the post
by hand or with any tool when the Hammer is in operation.

• Do not exceed the vehicle's rated operating load. Use sufficient counterweights. Move
the vehicle slowly when the attachment is raised.

• Carry the load low. 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 Hammer on steep hillsides. When operating the Hammer on uneven
or hilly terrain, position the vehicle with the attachment uphill. With the attachment
downhill, the vehicle could tip when attempting to raise the attachment. Consult your
vehicle operator’s manual for maximum incline allowable.

• Always shut off the vehicle engine and remove the key before dismounting the vehicle,
adjusting the attachment, or servicing the Hammer. Never leave equipment unattended
with the vehicle running.

• Never attempt repairs or adjustments while the equipment is in operation.

• 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.

• Always use care when operating the Hammer. Most accidents occur because of neglect
or carelessness.

Safety is a primary concern in the design, manufacture, sale, and use of Hammers. Danuser
confirms to you, our customer, our concern for safety.

Filtration Requirements:

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.

NOTE

• A low pressure type filter can be installed in the return line from the control valves to

• 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

Pressure and Flow Requirements:

• The Hammer is designed to operate up to 30 GPM and 1500 – 3000 PSI.

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 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.

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 Hammer, 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 attachment.

Valve Requirements:

• The hydraulic system used to power the Hammer 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 Hammer 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 Hammer in such a way
that high pressure in either line will be relieved to the other line.

Hydraulic Fluid Selection Requirements:

• Premium grade petroleum based fluids will provide the best performance.

• Fluids that contain 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 of the Hammer is 100-200 SUS (20-43 cST).

Add Additional Weight

For tough driving conditions or large posts, additional weight can be added up to 500
lbs. total hammer weight by purchasing a weight kit or by adding weight. Add weight in
a variety of ways: logging chain, metal punch slugs, lead tire weights, etc. Do not use
concrete or sand, as damage may result.

Personal protection
equipment including hard
hat, safety glasses, safety
shoes, gloves, and ear
plugs are recommended
during assembly,
installation, operation,
maintenance, service,
removal, or movement of
the attachment.

Make sure the hammer weight catch is visible through the viewing slots on the
back of the case.

Remove the retention pin from the top of the case. Insert a hook into the lifting
eye located on the top of the weight. Lift the weight out of the Hammer with a
hoist, forklift, or another vehicle. Set the weight on the ground.

Remove the weight cover by loosening the two lock nuts. It may be necessary to
use a hammer and punch in order to break the weight cover loose.

Place the additional weight into the cavity of the hammer weight until full.

Reinstall the weight cover using the two washers and lock nuts, making sure to
seal the cover with silicone sealant.

Lower the weight back into the Hammer and reinstall the retention pin.

Retention

Pin

Because of the weight
of some components,
and because some
components are difficult
to balance, two people are
required for safe
assembly and installation
of this equipment.

Do not tilt or operate the Hammer without the retention pin
in place. The hammer weight could slide out of the Hammer
and cause serious injury or death.

Prepare the Vehicle

Read and understand the manual for your vehicle before assembling or installing the
Hammer. The vehicle must be equipped with a universal quick attach hitch and auxiliary
hydraulics. The use of the Hammer may require the addition of counterweights to ensure
the attachment does not exceed the rated capacity of the vehicle.

Do not exceed the vehicle's rated operating load. If
necessary, use sufficient counterweights.

STEP 1:

Install the Hammer by following your vehicle operator's manual for installing an
attachment.

Make sure the Hammer is securely latched to the vehicle.
Failure to do so could result in separation of the attachment
from the vehicle.
