5.2
Functional description
Principle
The machine is a demolition hammer with a pneumatic percussion system.
It is driven by a gasoline engine.
The rotary movement of the drive engine is converted into a stroke movement
via a transmission and a crank gear.
The piston is moved forwards and backwards by the crank gear, this compresses
the air (forward movement) or generates a partial vacuum (backward
movement). Due to change in pressure the percussion piston is moved forward
and backwards (air cushion percussion system) and hits the tool.
The hood and operator's controls are decoupled from the percussion system by
a spring system. This spring system keeps vibrations away from the operator's
body if he for example presses his body against the hood while working.
Integrated shut-off device – RS (optional)
The machine has an integrated shut-off device for connecting to an external remote cut-off.
Via the remote cut-off, you can switch off several machines from a central location. This is for the safety of the operators, e.g. in track construction work.
If you wish to use your machine with a remote cut-off, please contact your
Wacker Neuson representative.
Low Vib (optional)
The machine has very low hand-arm vibration and allows fatigue-free working.

Emission Control System Information
Emission Control System Information
Source of Emissions
The combustion process produces carbon monoxide, oxides of
nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of
nitrogen is very important because, under certain conditions, they
react to form photochemical smog when subjected to sunlight. Carbon
monoxide does not react in the same way, but it is toxic.
Wacker Neuson utilizes lean carburetor settings and other systems to
reduce the emissions of carbon monoxide, oxides of nitrogen, and
hydrocarbons.
The U.S. and California Clean Air Acts
EPA and California regulations require all manufacturers to furnish
written instructions describing the operation and maintenance of
emission control systems.
The following instructions and procedures must be followed in order to
keep the emissions from your Wacker Neuson engine within the
emissions standards.
Tampering and Altering
Tampering with or altering the emission control system may increase
emissions beyond the legal limit. Among those acts that constitute
tampering are:
•Removal or alteration of any part of the intake, fuel, or exhaust
systems.
•Altering or defeating the speed-adjusting mechanism to cause the
engine to operate outside its design parameters.
Problems That May Affect Emissions
If you are aware of any of the following symptoms, have your engine
inspected and repaired by your servicing dealer.
•Hard starting or stalling after starting.
•Rough idle.
•Misfiring or backfiring under load.
•Afterburning (backfiring).
•Black exhaust smoke or high fuel consumption.
Emission Control System Information
Replacement Parts
The emission control systems on your Wacker Neuson engine were
designed, built, and certified to conform with EPA and California
emissions regulations. We recommend the use of genuine Wacker
Neuson parts whenever you have maintenance done. These originaldesign replacement parts are manufactured to the same standards as
the original parts, so you can be confident of their performance. The
use of replacement parts that are not of the original design and quality
may impair the effectiveness of your emission control system.
A manufacturer of an aftermarket part assumes the responsibility that
the part will not adversely affect emission performance. The
manufacturer or rebuilder of the part must certify that use of the part
will not result in a failure of the engine to comply with emission
regulations.
Maintenance
Follow the maintenance schedule. Remember that this schedule is
based on the assumption that your machine will be used for its
designed purpose. Sustained high-load or high-temperature operation,
or use in unusually wet or dusty conditions, will require more frequent
service.
OXYGENATED FUELS
Some conventional gasolines are being blended with alcohol or an
ether compound. These gasolines are collectively referred to as
oxygenated fuels. To meet clean air standards, some areas of the
United States and Canada use oxygenated fuels to help reduce
emissions.
If you use an oxygenated fuel, be sure it is unleaded and meets the
minimum octane rating requirement.
Before using an oxygenated fuel, try to confirm the fuel’s contents.
Some States / Provinces require this information to be posted on the
pump.
The following are EPA-approved percentages of oxygenates:
ETHANOL - (ethyl or grain alcohol) 10% by volume. You may use
gasoline containing up to 10% ethanol by volume. Gasoline containing
ethanol may be marketed under the name “Gasohol”. E85 fuel should
never be used, as it is an alternative fuel containing 85% ethanol, 15%
gasoline.
MTBE - (methyl tertiary butyl ether) 15% by volume. You may use
gasoline containing up to 15% MTBE by volume.
Emission Control System Information
METHANOL - (methyl or wood alcohol) 5% by volume. You may use
gasoline containing up to 5% methanol by volume, as long as it
contains cosolvents and corrosion inhibitors to protect the fuel system.
Gasoline containing more than 5% methanol by volume may cause
starting and/or performance problems. It may also damage metal,
rubber, and plastic parts of your fuel system.
If you notice any undesirable operating symptoms, try another service
station, or switch to another brand of gasoline.
Fuel system damage or performance problems resulting from the use
of an oxygenated fuel containing more than the percentages of
oxygenates mentioned above are not covered under warranty.

Emission Control System Information
OWNER’S WARRANTY RESPONSIBILITY:
As the engine owner, you are responsible for the performance of the
required maintenance listed in your owner’s manual. Wacker Neuson
recommends that you retain all receipts covering maintenance on your
engine, but Wacker Neuson cannot deny warranty coverage solely for
the lack of receipts or for your failure to ensure the performance of all
scheduled maintenance.
As the engine owner, you should be aware that Wacker Neuson may
deny you warranty coverage if your engine or a part has failed due to
abuse, neglect, improper maintenance or unapproved modifications.
You are responsible for presenting your engine to a Wacker Neuson
dealer as soon as a problem exists. The warranty repairs should be
completed in a reasonable amount of time, not to exceed 30 days.
If you have any questions regarding your warranty rights and
responsibilities, you should contact your local Wacker Neuson dealer.
WARRANTY COVERAGE:
Wacker Neuson engines sold after January 1, 1998, are covered by
this Emission Control System Warranty for a period of two years from
the date of delivery to the original retail purchaser. This warranty is
transferable to each subsequent purchaser for the duration of the
warranty period.
Warranty repairs will be made without charge for diagnosis, parts or
labor. All defective parts replaced under this warranty become property
of Wacker Neuson. A list of warranted parts is located on the next
page. Normal maintenance items, such as spark plugs and filters, that
are on the warranted parts list are warranted up to the required
replacement interval only.
Wacker Neuson
is also liable for damages to other engine
components caused by a failure of any warranted parts during the
warranty period.
Only Wacker Neuson approved replacement parts may be used in the
performance of any warranty repairs and must be provided without
charge to the owner. The use of replacement parts not equivalent to
the original parts may impair the effectiveness of your engine emission
control system. If such a replacement part is used in the repair or
maintenance of your engine, and an authorized Wacker Neuson dealer
determines it is defective or causes a failure of a warranted part, your
claim for repair of your engine may be denied. If the part in question is
not related to the reason your engine requires repair, your claim will not
be denied.
Emission Control System Information
TO OBTAIN WARRANTY SERVICE:
You must take your Wacker Neuson product along with proof of
original purchase date, at your expense, to any Wacker Neuson
authorized dealer during their normal business hours. Claims for repair
or adjustment found to be caused solely by defects in material or
workmanship will not be denied because the engine was not properly
maintained and used.
