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 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 maintenence of emission control systems.

The following instructions and procedures must be fol­lowed in order to keep the emissions from your WACKER
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.

Replacement Parts

The emission control systems on your WACKER engine
were designed, built, and certified to conform with EPA
and California emissions regulations. We recommend
the use of genuine WACKER parts whenever you have
maintenence done. These original-design 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 high­load 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
collectivly 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”.

MTBE - (methyl tertiary butyl ether) 15% by volume. You
may use gasoline containing up to 15% MTBE by vol­ume.

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.

BS65Y

Emission Control System Warranty

Your new WACKER engine complies with the U.S. EPA emissions regulations. WACKER provides the same emission
warranty coverage for engines sold in all 50 states.

YOUR WARRANTY RIGHTS AND OBLIGATIONS

All States

WACKER must warrant the emission control system on your engine for the period of time listed below provided there
has been no abuse, neglect or improper maintenance of your engine. Where a warrantable condition exists, WACKER
will repair your engine at no cost to you including diagnosis, parts and labor.

Your emission control system may include such parts as the carburetor, the ignition system and the catalytic converter.
Also included may be hoses, connectors and other emission-related assemblies.

MANUFACTURER’S WARRANTY COVERAGE:

The 1998 and later engines are warranted for two years. If any emission-related part on your engine is defective, the
part will be repaired or replaced by WACKER.

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 recommends that you retain all receipts covering maintenance on your engine, but WACKER
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 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 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
dealer.

WARRANTY COVERAGE:

WACKER 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. 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 is also liable for damages to other engine components caused by a failure of any warranted parts during
the warranty period.

Only WACKER 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 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.

1.14 Adjusting Ramming Stroke

When adjusting the ramming stroke, observe the following precautions to avoid injury to yourself and others.

!

WARNING

- Adjust stroke with machine standing upright and resting on a firm, level surface. Do not adjust stroke if the
machine is in an unstable position where it can easily tip or slide.

- Always stop engine before adjusting stroke. The clutch could engage, causing rammer to jump unexpectedly.

- Adjustment should be performed by one person and with no one else near the machine. The tool used to make
the adjustment could slip out of your hands and hit someone standing nearby.

To adjust ramming stroke:

1. Remove adjusting tool from cover. Open cover.

2. Check that arrow (a) on center of locking lever is

pointing up.

!

WARNING

If arrow is pointing down, the spring system is not
balanced and could cause the top half of the rammer
to drop unexpectedly while making the stroke adjust­ment. To balance spring system, stand behind the
rammer and use guide handle to rock machine back
and forth until you feel the spring system relax. The
arrow should now be facing up.

3. Insert adjusting tool (b) into bore on locking lever.

Make sure it is fully seated so it will not slip out. Steady
rammer by holding guide handle and use adjusting
tool to push locking lever straight down until it is
completely disengaged (refer to Operation 1 in illus­tration above).

3

1006SD66

4. Using adjusting tool, move locking lever until center
arrow is pointing at the desired stroke setting (Opera­tion 2).

!

WARNING

During this adjustment, tension is applied to the
spring system. This tension will release as the
locking lever is returned back to its locked position.
When this happens, the rammer will settle, causing
the handle and crankcase to drop down. The
movement is slight but happens quickly. Be aware
of this when moving locking lever.

5. Push or pull the adjusting tool to move the locking
lever back to its locked position (Operation 3). When
the locking lever is halfway between the locked and
unlocked position the spring system will settle and
move as described in warning above.

6. Remove adjusting tool. Close cover and lock it in
place with tool.

1.17 Low Maintenance Air Cleaner

This air cleaner is self-cleaning and uses the movement of the machine to shake dust and dirt loose from the air cleaner
element while the rammer is operating. Under normal operating conditions this element will not require cleaning and
should not be removed from the machine. If the element does become plugged with dirt, the engine will begin to lose
