CARRIER MACHINE COMPATIBILITY
These carrier weight ranges are intended as a guideline only. Other factors, such as
stick length, counterweights, undercarriage, etc., must be taken into consideration.
Mounting a HAMMER that is too heavy for the carrier machine
can be dangerous and damage the machine. Verify carrier
stability with hammer before transport or operation.
Mounting a HAMMER that is too small for the carrier machine can damage the
HAMMER, cause tool breakage and void Warranties. Please consult NPK Engineering
for specific detailed information.

NOTES:
1. Hydraulic operating pressure maximum is inlet pressure at the hammer with the oil at
operating temperature and with the gas charge set at the hot operating pressure. See
CHECKING THE HYDRAULIC PRESSURES section in Service Manual.
2. Circuit relief pressure is at least 500 psi (35 bar) above hammer operating pressure.
3. Cold gas charge is the initial set with the hammer at ambient temperature.
4. Hot gas charge is checked after 1 to 2 hours of running and with a system oil
temperature of 140° to 180°F (60° to 80°C). This is the preferred check.

HYDRAULIC INSTALLATION
NPK INSTALLATION KITS are available for virtually all compatible backhoe loaders,
excavators, and skid steers. Complete parts and instructions for the hydraulic
installation of the NPK HYDRAULIC HAMMER including valving and/or controls, hoses
and fittings, boom and stick tubing, and clamps are provided.
HAMMER LINES
Typically, the pressure line is arranged on the left side of the boom and the return line
on the right side. Flow to the hammer is controlled from an auxiliary valve on the carrier
or from an NPK supplied valve. Hydraulic oil is routed back to the tank thru the carrier’s
oil cooler and filter.
HAMMER CONTROL VALVE
NPK uses two general types of control systems, depending upon the carrier model:
1. CONTROL SYSTEM USING THE CARRIER AUXILIARY OR SPARE VALVE
SECTION.
This type of installation utilizes an existing carrier valve. Any additional parts, such
as a mechanical linkage, hydraulic pilot control valve, flow control valves, etc., are
furnished in the NPK HYDRAULIC INSTALLATION KIT. Special hydraulic pressure
control valves are not required. The NPK HYDRAULIC HAMMER operating
pressure is self-regulating.
2. CONTROL SYSTEM USING THE NPK MULTIVALVE.
For carriers not equipped with a suitable auxiliary or spare valve section, the NPK
HYDRAULIC INSTALLATION KIT includes a solenoid operated, priority flow control
valve to operate the NPK HYDRAULIC HAMMER. The NPK MULTIVALVE is
specifically designed for the operation of boom mounted attachments.

HYDRAULIC INSTALLATION
PREVENTION OF CONTAMINATION
1. A hydraulic hammer is harder on oil than using a bucket, so the oil is apt to
deteriorate and breakdown sooner. Neglect of the oil system can not only damage
the hydraulic hammer but also cause problems in the carrier which could result in
damaged components. Care should be taken to check for contamination of the oil
and to change it if it is found contaminated. Oil sampling at regular intervals is
highly recommended.
When the hydraulic oil shows low viscosity and bubbles, this indicates that the oil
is deteriorated. If the oil is dark brown and gives off an offensive odor, it is
severely deteriorated. Change the oil immediately.
When the oil is clouded, or the oil filter has become clogged, it indicates that the
oil is contaminated. Change the oil immediately!
To change the contaminated hydraulic oil, drain the hydraulic system completely
and clean components. Do not mix new oil with the old.
2. Do not allow any contamination to mix with the oil. Take special care in preventing
contamination from entering the hydraulic system through the hose or tube
connection when changing the hydraulic hammer with the bucket.
3. Low oil level will cause heat build-up, resulting in deterioration of the oil. Also, it may
cause cavitation due to air mixing with the oil, leading to a damaged hydraulic
hammer and carrier components. Keep the oil at the proper level at all times.
4. Do not use the hydraulic hammer at an operating temperature higher than 180°F
(80°C). The proper operating oil temperature range is between 120°F (50°C) and
180°F (80°C). Since contaminated cooler fins causes reduced efficiency of the
cooler, keep the cooler fins clean at all times. Check the hydraulic oil cooling system
to be sure it is working effectively. The use of a heat gun is the best way to evaluate
if the cooler is working properly.
5. Water in the hydraulic oil will lead to damage of the hydraulic hammer and carrier.
Drain off water and foreign matter from the hydraulic tank at specified intervals.
When out of service, the hydraulic hammer should be stored indoors.
CHANGING THE FILTER ELEMENT AND HYDRAULIC OIL
Change the filter element and hydraulic oil at the intervals described in the operation
manual of the Skid Steer when using a hydraulic implement. Another method is to set
up an oil sampling schedule and change accordingly.

HYDRAULIC INSTALLATION
HYDRAULIC QUICK DISCONNECTS
NPK recommends against the use of non-NPK quick disconnects on
hydraulic circuits operating NPK Products.
1. The hydraulic pulsations caused by hydraulic hammer operating can cause internal
pieces of non-NPK quick disconnect to disintegrate. These pieces would migrate
into the hammer, causing damage.
2. If quick disconnects are used when the hammer is removed from the excavator, the
quick disconnects should be capped to keep them clean. If this is not done,
contamination on the disconnect will be flushed into the hammer when re-connected.
This, again, can cause damage.
3. Most quick disconnects create a restriction in the circuit. NPK Hammers are not
back pressure sensitive, but restrictions cause unnecessary heating of the oil. Also,
the pressure required to operate the hammer, plus the restriction of the disconnects
may push an older, low pressure, carrier machine to the limit of its hydraulic system.
This would interfere with proper hammer operation. However, the NPK approved
quick disconnects are properly sized so that the hammer operation is not
affected.

HYDRAULIC INSTALLATION
HYDRAULIC QUICK DISCONNECTS
If hydraulic quick disconnects are used with the NPK Hammer, it is recommended that
the following precautions be followed.
1. Periodic inspection of both male
and female ends (A) is
recommended to ensure the
couplers are in good working
condition. Failure to inspect
couplers may result in pieces from
a damaged or failed coupler to be
injected into the hammer or parts
of the coupler returned to the
machine.
2. Check for dirt, dust, and debris on
both couplers before coupling.
3. Be sure that the couplers (B) are
completely seated together.
4. When replacing couplers, be sure
that couplers are replaced as a set,
male and female. Do not use one
new end and one used end.

LUBRICATION
GREASING PROCEDURE
Manual greasing for hammers without AUTOLUBE system.
1. Place the hammer in a vertical position, applying enough downforce to push the tool
up into the hammer. This prevents grease from entering piston impact area.
2. Turn the machine off.
3. Grease the hammer until grease begins to come out around the tool and lower
bushing.
APPLY DOWNFORCE TO PUSH TOOL UP INTO HAMMER
NOTE: USE A GOOD QUALITY EP #2 LITHIUM BASED GREASE WITH WEAR
INHIBITING ADDITIVES, SEE PAGES 13, 14, AND 15.

- 13 -
LUBRICATION
CORRECT GREASE AND GREASE INTERVALS
Proper hammer maintenance requires a sufficient supply of the correct grease to the
tool (chisel). The tool must be pressed against a hard surface until it stops up inside the
hammer. This prevents grease from entering piston impact area and ensures proper
distribution of grease between the tool and tool bushings.
GREASE INTERVALS
If the hammer is not connected to an Autolube system, see page 15, the hammer must
be greased at regular intervals to get the best life from the tool and tool bushings.
There are two ways to determine grease intervals:
First, grease the hammer at the beginning of the job until grease comes out between
the tool and the lower tool bushing. Run the hammer until the shank of the tool starts to
look dry. This determines the time interval for the greasing of this particular hammer on
this particular job. Typically, this is 1 to 4 hours. Also, note the amount of grease
needed to re-grease the tool. This gives you the amount of grease and how often it
must be applied. An example would be that a particular hammer, on a particular job,
requires half a tube of grease every 3 hours. This would be the greasing schedule you
would set up. If this hammer was moved to another job, another grease schedule may
have to be determined.
Second, if you can’t control the grease schedule, such as rental units, then have the
operator grease the hammer once every hour of hammer operation. Again, grease the
hammer until grease comes out between the tool and tool bushing. This is usually more
often than required, but is far cheaper than replacing prematurely worn tools and tool
bushings.
CORRECT GREASE
The type of grease used is very important. NPK recommends a lithium soap base EP
(Extreme Pressure) NLGI #2 Grease, with Moly (Molybdenum Disulfide) or other
surface protecting additives. A high drop point (500° F, 260° C) grease is desirable.
On the following page is a list of commonly available greases, by manufacturer and
brand name that meet NPK’s recommendations. NPK does not endorse any one brand
as being superior to another. If you or your customers use a brand not listed, please

AUTOLUBE SYSTEMS
An automatic greasing system is recommended
to reduce hammer tool and tool bushing wear.
The NPK AUTOLUBE System is designed to
automatically provide a continuous supply of
grease to the hammer tool and tool bushing –
increasing tool and tool bushing life by reducing
wear. The AUTOLUBE pump is capable of
pumping EP2 grease in cold weather. The
pump output is adjustable according to the
requirements of the hammer model and to
compensate for tool bushing wear.
NPK hammer models E203, E204, E205 and E207 have a connection port (A) for an
automatic greasing system (C). Do not use the plugged port in the tool holder
assembly. Use grease fitting (B) for manual greasing.
Refer to the NPK AUTOLUBE Instruction Manual for details.

- 16 -
LUBRICATION
AUTOLUBE GREASE LINE PRE-FILLING
It is mandatory that the supply line from the Autolube main pump to the connection on
the hammer is primed with grease before it is used. Failure to do this will result in no
grease being administered to the hammer tool for two to three hours. This can and will
result in severe galling of the tool and tool bushing.
PRIMING THE GREASE LINE
1. Place the hammer (KK) in a vertical position, applying enough down force to push the
tool up into the hammer.
2. Turn the machine off.
3. Fill the NPK Autolube pump reservoir with a power greaser through the fill fitting on
the side of the pump, or from the top by removing the fill cover. Use a premium
quality grade EP-2, high temperature grease with wear inhibiting additive.
4. Disconnect the grease line (29) from the
Autolube main pump cartridge (a4).
5. Install part number G100-8050 hose fill
adapter (a13) onto the #6 JIC end of the
grease line (29) previously removed.
6. Remove the grease line (29) at the
hammer (KK).
7. Attach a grease gun (t37) or power
greaser to the grease line (29) leading to
the hammer.

- 17 -
LUBRICATION
AUTOLUBE GREASE LINE PRE-FILLING
8. Pump grease through the grease line
(29) until a steady stream of grease (28)
is realized at the opposite (hammer) end.
9. Re-attach the grease line (29) to the
hammer (KK).
10. Pump twenty more shots of grease into
the grease line (29). This will prime the
hammer cavity and pre-lube the tool.
Look for grease coming out around the
tool (HH) at the tool bushing (see
arrow).
11. Remove the hose fill adapter (a13) and
re-connect the grease line (29) to the
Autolube pump (FZ).
NOTE: If the Autolube has run out of grease, the above procedure should be
used to purge all the air out of the line before using the hammer. Failure
to do this will result in an intermittent supply of grease to the hammer.

LUBRICATION
LUBRICANT TERMS AND DEFINITIONS
TERM DEFINITION
ADHESIVE The ability of grease, gear lubricant or oil to cling to
metal.
ANTI WEAR AGENTS Used to help combat metal-to-metal contact, thus
reducing wear.
COHESIVE The ability of grease, gear lube or oil to cling to itself,
thus resisting tearing apart.
CONSISTENCY Consistency of grease is its hardness or firmness. It is
determined by the depth in millimeters to which the cone
of a penotrometer sinks into a sample under specified
conditions. Consistency of grease may be influenced by
the type and amount of thickener, viscosity of oil, working
and other factors.
CONTAMINATION Foreign material that could damage a part.
DROPPING POINT The minimum temperature at which the oil in a grease
subjected to heat begins to actually drip and breakdown.
EXTREME PRESSURE
AGENTS Additives that under extreme pressure form an adherent
film on metal surfaces, thus forming a film of protection.
FILM STRENGTH Film strength is defined as the tendency of oil molecules
to cling together. It is the ability of those molecules to
resist separation under pressure between two metals and
to hold these metal surfaces apart.
FRICTION The resistance to fluid flow in a hydraulic system. (An
energy loss in terms of power output.)
GALLING Surface damage on mating, moving metal parts due to
friction. A severe form of adhesive wear.
LUBRICATION Use of a substance (grease, oil, etc.) to reduce friction
between parts or objects that move against each other.
NLGI A rating given to a grease from the National Lubricating
Grease Institute. This rating determines the hardness of
the grease and goes on from a 000 to a 6 rating. Most
greases are NLGI #2 rated.
OILINESS Oiliness is measured of the coefficient of friction of a
lubricant. Oiliness or lubricity depends on the adhering
characteristics of an oil. It is determined by the attraction
between the molecules of the oil and the molecules of
another material. Of two oils having the same viscosity
but different degrees of fluid friction, the one with the
lower friction index has the higher degree of oiliness.
PUMP A device which converts mechanical force into hydraulic
fluid power. Basic design types are gear, vane, and
piston units.
