II. SAFETY INSTRUCTIONS
FAILURE TO COMPLY WITH THE FOLLOWING SAFETY
INSTRUCTION AND LOCAL REGULATIONS WILL RESULT IN
PROPERTY DAMAGE, SEVERE INJURY OR DEATH.
The following safety instructions are contained in the text of this manual. Read the entire
manual before operating the hammer. Remember SAFETY IS UP TO YOU! Good safety
practices not only protect you but also protect the people around you.
The following signal words will be found in this manual and may also be found in other
manufacturer’s manuals. These words are intended to alert the operator to a hazard and the
degree of severity of the hazard.
indicates a hazardous situation which, if not avoided, will result in death
or serious injury.
indicates a hazardous situation which, if not avoided, could result in
death or serious injury.
indicates a hazardous situation which, if not avoided, could result in
minor injury or moderate injury.
indicates a property damage message.
1. For each lift the operator must review the excavator lifting
capacity to determine that the weight of the hammer/ Rototilt assembly plus
the load being lifted is within the rated capacity of the excavator.
2. Check that all personnel are clear of the V-5Esc unit prior to
start up.
3. Keep hands clear of all three clamps at all times.
4. Always use pile handling/ safety line to attach the pile to the
hammer.
5. Leave the pile handling/ safety line attached to the pile at all
times if the pile is not stuck securely in the ground.

4 | SAFETY INSTRUCTIONS
6. The V-5Esc side clamp attachment is designed to handle
a single pile with a MAXIMUM weight of 2 tons. Appropriate pile handling
rigging should be supplied by the end user to handle the pile in a safe manner.
Attach safe handling cable(s) to lifting eye(s) on the hammer to allow for pile
placement in the jaws as shown in gure 1.
7. Before closing the jaws of the bottom clamp, assure that the
pile head is rmly against the clamp housing. Gripping the pile with merely
the lower end of the jaws will damage the jaws, the clamp slide and/ or other
clamp assembly components.
8. Stand a safe distance away from the pile and from below the
V-5Esc hammer during vibrating operations. Any unobserved or unconnected,
loose nut or other fastener may fall.
9. Do not unclamp the jaws from the pile while the hammer is
vibrating.
10. Do not pull in excess of the rating of the V-5Esc hammer’s
suspension assembly or excess stresses will be put on the suspension
assembly damaging one or more parts.
11. Whenever the V-5Esc hammer is observed “dancing or
chattering” in place, it should be hoisted until the action stops. Failure to
move a pile with the hammer “dancing or chattering” should be cause to
promptly abandon the effort before serious damage is done to the hammer.
To continue operations the obstruction must be removed or penetrated by
switching to another driving system such as a larger vibro or a MKT diesel or
air pile hammer.

SAFETY INSTRUCTIONS | 5
IMPORTANT SAFETY INFORMATION
Virtually all accidents that involve product operation, maintenance and repair are
caused by failure to keep fundamental safety rules or precautions. An accident can
often be avoided by identifying potentially unsafe situations before an accident
occurs. A person must be alert to potential hazards. This person should also have the
necessary training, skills and tools to perform these functions properly. Do not operate
or perform any lubrication, maintenance or repair on this equipment until you have read
and understand the applicable information in the Operation and Maintenance Manual.
MKT cannot anticipate every possible circumstance that might involve a potential
hazard. The warnings in the manuals and on the equipment are therefore not all
inclusive. If a tool, procedure, work method or operating technique not specically
recommended by MKT is used, you must satisfy yourself that it is safe for you and
others. You should also ensure that the equipment will not be damaged or made unsafe
by the operation, lubrication, maintenance or repair procedures you choose.
The information, specications, and illustrations in the manuals are based on
information available at the time it was written. The specications, torques, pressures,
measurements, adjustments, illustrations, and other items can change at any time.
These changes can affect the service given to the product. Obtain the complete and
most current information before starting any job. MKT and MKT distributors have the
most current information available.
GENERAL HAZARD INFORMATION
Use caution when removing ller caps, grease ttings, pressure taps, breathers or drain
plugs. Hold a rag over the cap or plug to prevent being sprayed or splashed by liquids
under pressure.
Wear a hard hat, protective glasses, hearing protection and other protective equipment
as required by job conditions.
Do not wear loose clothing or jewelry that can catch on controls or other parts of the
equipment.
Make certain all protective guards and covers are secured in place.
Use all cleaning solutions with care.
Never put maintenance uids into glass containers since glass containers can break.
Report all needed repairs.

6 | SAFETY INSTRUCTIONS
UNLESS INSTRUCTED DIFFERENTLY,
PERFORM ALL MAINTENANCE AS FOLLOWS
Stop the hammer or drill. Stop the engine.
Disconnect the battery whenever performing any maintenance or before servicing the
electrical system. If the engine has electric starters, disconnect and tape the battery
ground leads to prevent accidental starting.
Do not attempt any repairs or adjustments to the engine or hammer or drill while it is
running.
Do not attempt repairs you do not understand. Use proper tools; replace or repair
broken or damaged equipment.

manual.
PRESSURIZED AIR AND WATER
Pressurized air can cause personal injury. When using pressurized air for cleaning,
wear a protective face shield, protective clothing and protective shoes.
The maximum air pressure must be below 30 psi (205 kPa) and maximum water
pressure must be below 40 psi (275 kPa) for cleaning purposes.
FLUID PENETRATION
Wear eye protection at all times when cleaning the cooling system. Pressurized water
could cause debris and/or hot water to be blown and result in personal injury.
Always use a board or cardboard when checking for a leak. Escaping uid under
pressure, even a pin-hole size leak, can penetrate body tissue, causing serious injury or
possible death.
If uid is injected into your skin, it must be treated by a doctor familiar with this type of
injury immediately.

closer to work if hoses do not reach.
Do not operate this equipment with hydraulic hoses that are damaged or kinked.
Replace damaged hoses immediately.
Do not lift, or support, hydraulic hoses with wire rope slings.
Do not pull kinks in the hoses. Kinks will reduce the hose safety factor by 50 percent.
Do not bend or strike high pressure lines. Do not install bent or damaged lines, tubes or
hoses.
Repair any loose or damaged fuel and oil lines, tubes and hoses. Leaks can cause res.
Inspect all lines, tubes and hoses carefully. Do not use your bare hands to check for
leaks. Tighten all connections to the recommended torque.
Check for the following:
- End ttings damaged, leaking or displaced.
- Outer covering chafed or cut and wire reinforcing exposed.
- Outer covering ballooning locally.
- Evidence of kinking or crushing.

EXCAVATOR REQUIREMENTS | 11
IV. EXCAVATOR REQUIREMENTS
A. The excavator size, stick width and pin dimensions must be compatible with the
Rototilt width and pin dimensions.
B. The excavator must be equipped with a uni-directional auxiliary circuit that can
supply80gpmtotheV-5Escat3,000psi.Theauxiliarycircuitowmusthavepriority
overtheboomandstickfunctions,orgreaterowandadditionalmodicationsmay
be required to maintain hammer speed when operating boom or stick functions.
Ifexcavatorisnotequippedwithpriorityowauxiliarycircuit,hammerspeedwill
decrease when boom, stick or bucket function is activated.
C. Theauxiliaryhydrauliccircuitmustsupplyatleast80gpmandmustowoilinone
directiononly(uni-direction),itcannothavereverseow,ordamagetotheV-5Esc

switch, not a bi-directional foot pedal
D. The excavator must have adequate lifting capacity to lift the combined weight of the
hammer and pile at the required working radius.
E. The Rototilt RT80 has a maximum connecting pin size of 90mm and
a maximum digging force of 44,960 lbs. If using an excavator with larger than 90mm
pins or more than 44,960 lbs of digging force you must reduce the pin size to 90mm
and lower the digging force to 44,960 lbs. Consult your excavator supplier for the
properwaytomakethesemodications.

12 | SYSTEM SET-UP INSTRUCTIONS
V. SYSTEM SET-UP INSTRUCTIONS
A. HP-185T3A HYDRAULIC POWER UNIT
The HP-185T3A Hydraulic Power Unit is assembled on a Skid Base which also serves
asafueltank.Theskidbaseisttedwithasteelliftingbailwithaliftingeye.Thepower
unit is thus designed to be lifted by a crane line using a chain of adequate strength.
LocatetheHP-185T3APowerUnitonrmgroundwithanunobstructedoperatorviewto
the intended operation of the V-5Esc hammer.
B. CONNECTION OF HOSES
All V-5Esc hammers are thoroughly tested at the factory and consequently all hoses
willbelledwithhydraulicuid.Generally,thehosebundleassemblylledwith
oil, is disconnected from the hydraulic power unit. Therefore, it is necessary when
reconnectingtomakethecorrecthoseconnectionstothepowerunit.Thereareve
hoses in the bundle, each 100 feet long, two 1-1/4” I.D. lines for the hydraulic motor, two
3/4” I.D. lines for the hydraulic clamp assembly and one 3/4” I.D. line for the case drain.
Hose connections at the hydraulic power unit are made easily by quick disconnects with
checkvalves.Ifhosesarereplacedorareotherwiseunlledwithoil,takenecessary
stepstollthembeforestartingthehammer.
1. When the hoses are attached to the vibratory unit, care should be made to have the
bundle hanging free. Extreme care should be made at all times not to kink any of the
hoses.
As an example, the motor line 1-1/4” I.D. hoses have a minimum bend radius of 16-
1/2”. Even though these hoses have a minimum bursting pressure of 12,000 PSI, a
kink will weaken the multiple spiral wire wrap reinforcement and ruptures could result
at high operating pressures.
Any damaged hose within the hydraulic power unit hose bundle or vibratory
hammer should be replaced with a hose of equivalent ratings.
2. Before making any hydraulic hose connections, assure that the connectors are
wiped clean of any dirt or contamination to prevent damage to the components in the
hydraulic system.
3. Do not permit mobile equipment to run over the hydraulic hose bundle. The hydraulic
hoseinthebundle,eventhoughlledwithhydraulicoil,isnotabletowithstand
external compression forces.
4. The ends of the hoses in the hose bundle should be carefully wiped clean and
connected, according to size, to the short hoses which are part of the V-5Esc
Assembly.

SYSTEM SET-UP INSTRUCTIONS | 13
5. Make it a habit whenever hydraulic lines are subsequently disconnected to
immediately cap or plug them to avoid becoming dirty and introducing contamination,
into and damage to, the components of the hydraulic system. Assure that the caps
and plugs are wiped clean of any dirt or contamination before using.
C. V-5Esc DRIVER/EXTRACTOR
  TheV-5Eschammerisfactoryttedwithitssuspensionassemblyandisshippedaton
its side. It is designed to receive a 7/8” multiple loop wire rope sling properly sized and
clampedtoprovideafactorofsafetyofvetimesthe30tonmaximumlinepullcapacity
of the hammer, which in turn, can be slipped over a lifting crane hook. The V-5Esc
hammer can be lifted from the horizontal to the vertical without danger of excessive
stresses upon its connecting parts or structure.
1. Hanging in the air, the V-5Esc hammer should be hoisted, swung, and rotated to
assure that the hose bundle hangs free of any loops or entanglements.
2. Manipulating the V-5Esc hammer in the air during the foregoing procedure, as well
as later when setting the hammer upon a pile, will be made possible by fastening a
ground handling rope to one of the V-5Esc Clamp Jaw Shields before hoisting the
hammer aloft.
D. V-5Esc JAW SHIELDS
The Jaw Shields are generally shipped connected to the V-5Esc Clamp Assembly.
Before using the V-5Esc, assure that the Jaw Shields are tightly connected (each with
four hex head cap screws and lock washers) to the V-5Esc Clamp Assembly. The Jaw
Shields not only act as guides for positioning the V-5Esc on a standing pile, but are also
necessarytoprotectthejawsandtheclampassemblyfromunnaturalimpactshockand
resulting damage.

14 | START-UP PROCEDURES
VI. START-UP PROCEDURES
A. ENGINE FLUIDS
Make all lubricant, fuel, radiator, and preventive maintenance checks recommended
in the Engine Manufacturer’s Operating and Maintenance Manual before starting the
diesel engine.
B. HYDRAULIC FLUID
  CheckthelevelofthehydraulicuidinthereservoirontheHP-185T3APowerUnit.Do
notoperatetheHP-185T3Awiththehydraulicoillevelbelowthegauge.Ifhydraulicuid
must be added to the system, do not allow foreign matter to enter the hydraulic system
and use proper hydraulic oil for the HP-185T3A system. See the lubricant and hydraulic
uidrequirementsfortheV-5Esc/HP-185T3Asystem.
C. HYDRAULIC VALVES
The hydraulic valves in the HP-185T3A Power Unit have already been set for proper
pressures during the factory break-in and operation of the V-5Esc/HP-185T3A system.
DO NOT MAKE ADJUSTMENTS TO THE VALVES WITHOUT THE ASSISTANCE OF
A FACTORY TRAINED SERVICE REPRESENTATIVE.
  Thehydraulicreturnlinelterislocatedonthebacksideofthehydraulicreservoir.
Thelterhasafullsizebypassvalvethatprotectsthelterelementandsystemwith
aminimumofpressureloss.Therefore,thelter,asitbecomesclogged,willbypass
contaminatedoiltothetank.Frequentchangesofthelterelementwillberequired.
D. HYDRAULIC SYSTEM CIRCUITRY
The repetitive functions to be performed hydraulically for the operation of the V-5Esc
hammer are to clamp onto a pile, vibrate the pile, stop vibrating, and unclamp from the
pile. A basic open loop hydraulic circuit has been used with a single pump performing
both clamping and vibrating operations. The principle of using one pump is dependent
on a clamping hydraulic cylinder that has an integrated holding pressure check valve,
meaning once the pressure has been applied and immediately removed, the pressure
will be locked into the cylinder. The hydraulic control valve consists of an inlet section
with a pressure relief cartridge, a motor work section, a cylinder work section with work-
port relief, and an outlet section.

andentersthegear-typepump.Aftertheowleavesthehydraulicpumpitentersthe
directional control valve which will be used to operate either the clamp circuit or vibrate
circuit. A quick and full movement of the right-hand control lever will operate the clamp
close cylinder in a short amount of time. This control lever will spring back to the neutral
position and by the use of a pilot operated check valve, maintain clamping pressure.
The second control lever will operate the vibrate circuit. This control lever is detented
and may only be pulled toward the operator or pushed to the neutral position.
Warm oil returning from the control valve back to the tank will be directed through an oil
coolerthenareturnlinelterbeforeenteringthetank.Cooloilwillselectapathwhich
willbypasstheoilcoolerandenterthetankthroughthereturnlinelter.
E. CHARACTERISTICS OF THE V5C/HP-185T3A
The dynamic force generated by the V-5Esc hammer will vary according to the
operatingfrequency.Thetwoeccentricweightsinthehammerarexedinsizeand
the resulting dynamic force of the hammer is directly proportional to the square of the
frequency.Thepowerofthehammerisgenerallyreferredtoasthehydraulicowand
pressure of the hydraulic motor. The drop in hammer frequency while driving a pile is
mainly a result of both motor and pump losses at elevated pressures, some engine
speed droop, and oil passing over the system relief valve.
  Thehydraulicpowerunitenginespeeddeterminespumpow.Therecommended
engine operating speed is 2100 RPM, and the maximum operating drive pressure is
3000 PSI at the power unit. As the hammer resistance is increased calling for higher
pressure, hydraulic oil may pass over the relief valve causing the hammer to slow down.

DRIVING MODE
A. OPERATING THE V-5Esc SYSTEM - DRIVING MODE
1. First, check that the lifting capacity of the excavator, at the working radius, exceeds
the combined weight of the V-5Esc assembly and the pile. Then, lift the pile using
an appropriately sized cable between the pad eye on the suspension assembly and
theliftingholeinthepile.(Refertogures1and2).Oncethepileishangingnearly
vertical,guideitintothehammerjawsorthreadthepileintoanalreadydrivenpile.
Positionthejawsonthepile(seegure2)andclosethejawsandstartthehammer.
The vibration, coupled with the down crowd force of the excavator drives the pile. Do
not exceed the down crowd force rating.
Always use the pile handling/ safety line to attach the pile to the
hammer.
2. Cut pile handling holes 2ft. or more above center of the pile on either side of center
asrequiredtopositionpileinjawsasshowningure1.
Figure 1
3. The worksite needs to be level to maximize the speed of handling and driving the
pile.
4. As soon as headroom allows, move the pile to the bottom clamp to maximize driving
speed.
5. Thesideclampjawsareintendedtobeusedtostartanddrivethepileinsoftdriving
conditions. For best results and longer hammer life, the bottom clamp should be
used whenever possible. When using the side clamps, line pull should be limited to
15tonsandcrowdforcelimitedto10tons.Ifthesideclampjawssliponthepilestop
the hammer and move to the bottom clamp.
6. TheV-5Escwillvibratewiththejawsopenedorclosed. Do not start
hammer with jaws open.
7. Always maintain proper vertical alignment between the
suspension and pile when driving or pulling the pile.

OPERATING INSTRUCTIONS | 17
8. Occasionally the inability of the V-5Esc hammer to continue to move a pile will
be the result of the pile striking an impenetrable soil material or an obstruction.
The observable action of the V-5Esc hammer and clamped pile will be to note a
considerable fall-off of drive pressure and the exciter will “dance” in place often
causing erratic interaction of the V-5Esc exciter and its suspension assembly. If the
V-5Esc is mounted to an excavator or backhoe do not apply more crowd force than
the maximum recommended.
Whenever the V-5Esc hammer is observed “dancing or
chattering” in place, it should be hoisted until the action stops. Failure to
move a pile with the hammer “dancing or chattering” should be cause to
promptly abandon the effort before serious damage is done to the hammer.
To continue operations the obstruction must be removed or penetrated by
switching to another driving system such as a larger vibro or a MKT diesel or
air pile hammer.
For each lift, the operator must review the excavator lifting
capacity to determine that the weight of the V-5Esc/Rototilt assembly plus the
load being lifted is within the rated capacity of the excavator.
Keep hands clear of all three clamps at all times.
Leave the pile line attached to the pile at all times that the pile is
not stuck securely in the ground.
The V-5Esc side clamp attachment is designed to handle a single
pile with a MAXIMUM weight of 2 TONS. Appropriate pile lifting rigging should be
supplied by the end user to handle the pile in a safe manner. Attach cable(s) to
lifting eye(s) on the hammer to allow safe handling of the pile and placing it in the
jaws as shown in gure 2.

EXCAVATOR MOUNT
B. OPERATING THE V-5Esc SYSTEM - EXTRACTING MODE
1. Forpileextractingoperations,theV-5Eschammershouldbettedwithashackle
and an auxiliary line attached to the pad eye on the suspension assembly. The
V-5Esc hammer is clamped to a steel sheet pile to be pulled and the auxiliary line is
fastened into a lifting hole in the pile. The V-5Esc hammer is operated to extract the
pile until the pile can be easily lifted out of place exclusively by the extraction force
of the excavator. The V-5Esc hammer is then stopped by pushing the vibrate lever
to neutral. The pile is pulled out of the ground and the hammer and pile are swung
to where the pile will be stacked. The lower end of the pile is set on the ground
andtheV-5Eschammerjawsareopenedallowingthepiletohangbythelineand
shackle. The V-5Esc hammer and pile are then lowered to the ground where the line
is disconnected from the pile.
2. Thesideclampjawsareintendedtobeusedtopullthepileinsoftextracting
conditions. For best results and longer hammer life, the bottom clamp should be
used whenever possible. When using the side clamps line pull should be limited to
15tonsandcrowdforcelimitedto10tons.Ifthesideclampjawssliponthepilestop
the hammer and move to the bottom clamp.
Do not unclamp the jaws from the pile while the hammer is
vibrating.
3. The amount of pull which can be exerted on the V-5Esc hammer is limited by the
rating of the suspension assembly and the strength of the pile.
Do not pull in excess of the rating of the V-5Esc hammer
suspension assembly or excess stresses will be put on the suspension
assembly damaging one or more parts.
4. Always maintain proper vertical alignment between the
suspension and the pile when driving or pulling the pile.
