SAFETY
Safety notices in NPK Instruction Manuals follow ISO and ANSI standards for
safety warnings:
DANGER (red) notices indicate an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
WARNING (orange) notices indicate a potentially hazardous situation
which, if not avoided, could result in death or serious injury.
CAUTION (yellow) notices indicate a potentially hazardous situation,
which, if not avoided, may result in minor or moderate injury.
ATTENTION (blue) notices in NPK Instruction Manuals are an NPK
standard to alert the reader to situations which, if not avoided, could
result in equipment damage.
1. Operators and service personnel must read, understand and comply with the NPK
INSTRUCTION MANUAL.
2. Keep personnel and bystanders clear of the SHEET PILE DRIVER while in
operation.
3. Do not operate the SHEET PILE DRIVER without an impact resistant shield
between the SHEET PILE DRIVER and the operator.
4. The SHEET PILE DRIVER must not be operated unless the operator is in full
control of the carrier. Operate the SHEET PILE DRIVER from the operator’s seat
only.
5. Match the SHEET PILE DRIVER size to carrier according to NPK
recommendations. See the CARRIER MACHINE COMPATIBILITY section of this
manual.
6. Service personnel must be cautious handling pins and bushings when exchanging
the bucket for the SHEET PILE DRIVER. The carrier machine operator must move
the stick or boom only when directed by service personnel.
7. If it is necessary to hammer the boom pins in or out, beware of flying metal chips.
Eye protection be worn!
8. Do not operate the SHEET PILE DRIVER if the hydraulic oil temperature exceeds
180° F (80° C), or at higher than specified flow rates.
9. Be especially cautious around hydraulic lines. Hydraulic oil can be extremely HOT!
Avoid skin contact with hydraulic oil! It can cause severe burns!
10. Protect hands and body from hydraulic fluids under pressure. Escaping high
pressure fluid can penetrate the skin, causing serious injury. Avoid the hazard by
relieving the pressure form the hydraulic system before disconnecting any lines.
Search for leaks with a piece of cardboard or other object. If an accident occurs,
seek medical attention immediately! Hydraulic fluid injected into the skin
must be surgically removed immediately or gangrene may result!

SAFETY
11. Make daily visual inspections of all fasteners, boom pins, hoses, etc.
12. Do not make any alterations to the SHEET PILE DRIVER without authorization from
NPK Engineering.
13. Use only NPK supplied replacement parts. NPK specifically disclaims any
responsibility for bodily injury or SHEET PILE DRIVER damage that results from the
use of parts not sold or approved by NPK.
14. Be careful when you torque fasteners. An overstressed or damaged component
may fail.
15. Use the proper lifting equipment and tools when handling or servicing the SHEET
PILE DRIVER or components.
16. Important safety and operating decals are included with each SHEET PILE DRIVER
and HYDRAULIC INSTALLATION KIT. Keep them clean and visible. NPK will
replace decals free of charge as needed.

FORWARD
This manual has been written to give the necessary instructions for operating,
maintaining, and servicing the NPK Sheet Pile Driver. Read this manual before start-
up.
For help with any problems encountered, or additional information, contact your NPK
authorized Distributor.
Use replacement parts sold by NPK only. NPK is not responsible for failures resulting
from alterations not approved by NPK or substitution of parts not sold by NPK. Do not
operate the Sheet Pile Driver underwater without instructions from NPK Engineering.
SHEET PILE DRIVER APPLICATIONS
The excavator mounted Sheet Pile Driver is a mobile, self-contained unit that operates
anywhere a boom can reach. This versatile attachment reaches to the top of piling and
sheeting for driving or extracting in the toughest of conditions and in rough terrain areas.
APPLICATIONS INCLUDE:
•DRIVING PILE, SHEET.
•EXTRACTION OF PILING AND SHEETING.

MAINTENANCE
STANDARD PRACTICES
Maintenance of and repairs to the SHEET PILE DRIVER should be performed by an
experienced service technician, thoroughly familiar with all standard practices and
procedures, and most importantly, all safety precautions. The following is a review of
common standard practices to be followed when working with hydraulic equipment, and
is not meant to be all-inclusive. Rather, this review is presented as a reminder as to
some of the unique characteristics of hydraulic equipment.
•The prevention of foreign contaminant damage is critical when working with hydraulic
equipment. Protect exposed holes and parts to guard against entry of contaminants.
Install metal or plastic plugs/caps where applicable to prevent entry of debris into the
hydraulic system.
•Mark the location and position of mating parts as an aid to re-assembly. Mark
corresponding parts uniquely to reflect their relationship, including proper location,
position, orientation, and/or alignment.
DO:
•During assembly, observe all markings made during disassembly, and all
corresponding features of mating parts to ensure proper location, position, orientation
and alignment.
•During disassembly of a sub-assembly, place removed components on a clean, dry
surface, in proper relative position as an aid in re-assembly.
•Always inspect threaded areas on components. Repair or replace as required.
Never apply uncured thread adhesive to a fastener that has cured adhesive on it.
Clean the fastener and the threaded bore. A tap and die may be helpful for this task.
Be sure to remove loose debris from the threaded bore.
•Use care to avoid scratches, nicks, dents, or other damage to machined surfaces of
mating components.
•When securing a component, always tighten cap screws gradually in an opposing
pattern, applying the specific torque.
•Grease can be used to temporarily hold a part in place while the abutting part is
placed into position.
•Always use common sense and exercise standard safety precautions when working
with all tools and equipment required to maintain, repair or troubleshoot the SHEET
PILE DRIVER.

CARRIER 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 Compactor that is too heavy for the carrier machine is inefficient. The result
is an inadequate amount of downforce which can be dangerous and can damage the
carrier. Verify the carrier stability with the Compactor before transport or operation.
Mounting a Compactor that is too small for the carrier machine can damage the unit and
void the Warranty.
Consult NPK, if there is uncertainty whether the compactor model is compatible.
