SAFETY INSTRUCTIONS | 3
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-2Esc 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-2Esc 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-2Esc 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-2Esc hammer’s
suspension assembly or excess stresses will be put on the suspension
assembly damaging one or more parts.
11. Whenever the V-2Esc 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.

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.

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.
Make sure that all clamps, guards and heat shields are installed correctly to prevent
vibration, rubbing against other parts, and excessive heat during operation.

12 | OPERATING INSTRUCTIONS
V. OPERATING INSTRUCTIONS
DRIVING MODE
A. OPERATING THE V-2Esc SYSTEM - DRIVING MODE
1. First, check that the lifting capacity of the excavator, at the working radius, exceeds
the combined weight of the V-2Esc 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 4
tonsandcrowdforcelimitedto4tons.Ifthesideclampjawssliponthepilestopthe
hammer and move to the bottom clamp.
6. TheV-2Escwillvibratewiththejawsopenedorclosed. Do not start
hammer with jaws open.

OPERATING INSTRUCTIONS | 13
7. Always maintain proper vertical alignment between the
suspension and pile when driving or pulling the pile.
8. Occasionally the inability of the V-2Esc 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-2Esc 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-2Esc exciter and its suspension assembly. If the
V-2Esc is mounted to an excavator or backhoe do not apply more crowd force than
the maximum recommended.
Whenever the V-2Esc 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-2Esc/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-2Esc 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.
Figure 2

14 | OPERATING INSTRUCTIONS
EXCAVATOR MOUNT
B. OPERATING THE V-2Esc SYSTEM - EXTRACTING MODE
1. Forpileextractingoperations,theV-2Eschammershouldbettedwithashackle
and an auxiliary line attached to the pad eye on the suspension assembly. The
V-2Esc 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-2Esc 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-2Esc 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-2Eschammerjawsareopenedallowingthepiletohangbythelineand
shackle. The V-2Esc 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 4
tonsandcrowdforcelimitedto4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-2Esc 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-2Esc 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 and pulling the pile.

OPERATING INSTRUCTIONS | 15
WARNING!
The hammer and suspension must be kept in alignment with each other, and with the pile,
when driving or extracting. Failing to do so will result in damage to the jaws and clamp
cylinders.

16 | MAINTENANCE AND SERVICE INSTRUCTIONS
VI MAINTENANCE AND SERVICE INSTRUCTIONS
A. The V-2Esc hammer should be inspected regularly to help keep it in good operating
condition.Thetimeintervalbetweennecessaryadjustmentsandrepairsdepends
primarily on how much and how hard the machine has been used. Repair or replace
broken or damaged parts as soon as they are discovered. Periodic cleaning and
repainting will help keep all parts in better working order and prolong the machine’s life.
B. Inspect the V-2Esc hammer daily for loose fasteners.
Stand a safe distance away from the pile and from below the
V-2Esc hammer during vibrating operations. Any unobserved or unconnected,
loose nut or other fastener may fall.
C. Assure that the proper lube oil level is maintained in the V-2Esc exciter case. If the level
of oil is above the sight gauge or the lube oil volume is increasing, this will indicate that
thehydraulicmotorisleakinghydraulicuidthroughthemotordriveshaftseal.Theseal
leakage must be corrected immediately.
D. Daily Maintenance Check Lists - Check the entire unit prior to and during start-up each
shift.
a) Visually check all hoses for signs of damage or cuts that might cause hose failure
during operation. Be sure all connections are tight, especially the quick disconnects.
b) Look for any damage to the unit, in general that might cause it to fail when put into
operation.
c) Check the V-2Esc exciter case lube oil level.
d) ChecktheV-2Escclampingjawsforexcessivewear,cracksorloosefasteners.If
itisnecessary,theremovalofthemovablejawisdonebypushingoutthe3/4”roll
pineitherupordown.Thesingleverticalrollpincaptivatesthemovablejaw.The
xedjawisheldtightagainstthehousingwithtwoone-inchbolts.Also,operatingthe
V-2EsconpilingwithouttheJawShieldscouldresultinjawdamageifthehammeris
dropped onto the pile.

MAINTENANCE AND SERVICE INSTRUCTIONS | 17
E. After start up and the V-2Esc is vibrating, check as follows:
a) Visually, from a safe distance, inspect the hydraulic lines for leaks.
b) Beforeattachingtopile,openandcloseclampjawstoverifyfastandpositiveaction.
c) Be sure that there are no kinks in the lines and that they hang uniformly.
d) Always maintain a close check on the lifting cable to assure no fraying has occurred.
e) Check for overheated bearing housings.
F. Clamp Pressure - 2,500 PSI
G. Hydraulic Oil Temperature - 115 degrees Fahrenheit to 165 degrees Fahrenheit

18 | SERVICE TROUBLE SHOOTING
VII. SERVICE TROUBLE SHOOTING
1. Hydraulic Fluid Overheating
Running the V-2Esc overloaded for long periods of time (drive pressure at 2500 PSI)
dumps oil over the relief valve generating heat. Simply keep the V-2Esc operating but
relax the load below the 2500 PSI level and the temperature should drop.
2. Clamp Will Not Open or Close
Clamp line quick disconnects may not be engaged completely or their check valves
may be locked closed. There also may be too much air in the line to overcome clamp
cylinder friction.
3. Increase in Lube Oil Level
This is a sure sign that the hydraulic motor has a shaft seal failure. If submerged under
water, water may have seeped into the exciter case.
4. Exciter Overheating in Specic Local Areas
Checking the temperature of the bearing side covers will give an indication of an
overheating bearing. This bearing should be checked for excessive binding or wear.
Make sure the oil level is correct. It is not unusual for the temperature of the exciter
housing to go up to 200 degrees Fahrenheit if the V-2Esc is run at full frequency over an
extended period of time. Check the lower magnetic plug for metal which might indicate
excessive wear of gears or bearings.
5. Internal Noise in Exciter
Unusual noise in exciter generally means something is wrong - either a bearing gear, or
a hydraulic motor problem. Lube oil level should be checked.
6. V-2Esc Frequency Fluctuation

a hydraulic motor is failing, it is possible the frequency will not be constant especially as
the load goes a little higher (before going over relief). Check for exciter hotspots which
may indicate a bearing is failing.
7. Erratic Suspension Movement
Unusual soil conditions or underground boulders may cause a rebound and effect the
suspension isolation. If the V-2Esc when started comes up to speed too slowly, it is
possible the suspension will bounce out of sync with the frequency.
8. Slow Clamp Movement
Generally, slow clamping is caused by air in the hydraulic hoses. Bleed both directions
of the clamp cylinder.

travel is two and one eighth inches. Check clamping pressure. Air may be in the clamp
line requiring cylinder bleeding.
