1.2 Machine Description and Intended Use
The Wacker Neuson vibratory plate offers functionality and performance. The
compact design allows for compaction of mixed soils in the narrowest of
spaces– even in extremely narrow trenches.
This machine is optimally suited for a variety of compaction applications with
high speed and simple maneuverability. It has:
Compact design with central mounted, fully closed exciter for an even spread
of compactive force over the whole base plate.
Sturdy 4-stroke petrol or diesel engine with recoil starter is isolated from
vibration by rubber dumpers.
Vibration isolated reversible handle with throttle control for ease of
operation and reduced operator fatigue.
This machine has been designed and built strictly for the intended use
described above. Using the machine for any other purpose could permanently
damage the machine or seriously injure the operator or other persons in the
area. Machine damage caused by misuse is not covered under warranty.
The following are some examples of misuse:
Using the machine as a ladder, support, or work surface Using the machine to
carry or transport passengers or equipment Operating the machine outside of
factory specifications Operating the machine in a manner inconsistent with all
warnings found on the
machine and in the Operator’s Manual.
This machine has been designed and built in accordance with the latest global
safety standards. It has been carefully engineered to eliminate hazards as far
as practicable and to increase operator safety through protective guards and
labeling. However, some risks may remain even after protective measures have
been taken. They are called residual risks. On this machine, they may include
exposure to:
Heat, noise, exhaust, and carbon monoxide from the engine Fire hazards from
improper refueling techniques Fuel and its fumes Personal injury from improper
lifting techniques
To protect yourself and others, make sure you thoroughly read and understand
the safety information presented in this manual before operating the machine.

Operation
4 Operation
4.1 Preparing the Machine for First Use
1. Make sure all loose packaging materials have been removed from the
machine.
2. Check the machine and its components for damage. If there is visible
damage, do not operate the machine! Contact your Wacker Neuson dealer
immediately for assistance.
3. Take inventory of all items included with the machine and verify that all
loose components and fasteners are accounted for.
4. Attach component parts not already attached.
5. Add fluids as needed and applicable, including fuel, engine oil, and
battery acid.
6. Move the machine to its operating location.
4.2 Recommended Fuel
The engine requires regular grade unleaded gasoline. Use only fresh, clean
gasoline. Gasoline containing water or dirt will damage the fuel system.
Consult the engine owner’s manual for complete fuel specifications.
Use of oxygenated fuels
Some conventional gasolines are blended with alcohol. These gasolines are
collectively referred to as oxygenated fuels. If you use an oxygenated fuel,
be sure it is unleaded and meets the minimum octane rating requirement.
Before using an oxygenated fuel, confirm the fuel’s contents. Some states and
provinces require this information to be posted on the fuel pump.
Ethanol
The following is the Wacker Neuson approved percentage of oxygenates:
(Ethyl or grain alcohol) 10% by volume. You may use gasoline containing up to
10% ethanol by volume (commonly referred to as E10). Gasoline containing more
than 10% ethanol (such as E15, or E85) may not be used because it could damage
the engine.
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 above are
not covered under warranty.

Operation
4.3 Application
This plate is designed for compacting loose, granular soils, gravel, and
paving stones. It is intended to be used in confined areas and areas next to
structures such as walls, curbs, and foundations. Plates equipped with water
tanks can be used for compacting asphalt.
This plate is not recommended for compacting cohesive soils with a heavy clay
content. For cohesive soil, use a vibratory rammer or sheepsfoot roller.

4.5 Starting the Machine
Procedure
Perform the procedures below to start the machine.
1. Turn the fuel cock to the “ON” (OPEN) position (a1). Note: If the engine
is cold, move the choke lever to close position (b1). If the engine is hot,
set the choke to open position (b2).
2. Move the governor lever to left a little (c1).
3. Turn the engine switch to “ON” postion. (d1)
4. Pull the starter rope (e).
5. Note: Don’t allow the starter grip to snap back against the engine. Return
it gently to prevent damage to the starter.
6. Preheat the engine and push back the choke lever to the “OPEN” position
(f1).
7. Move the throttle lever to proper position to make the gasoline engine run
at required velocity. (g1)

Operation
4.7 Operation
Run the engine at full throttle and allow the plate to pull itself along at
its normal speed. When operating on an incline, it may be necessary to assist
the plate by pushing it forward slightly. When operating downhill, hold the
plate back slightly, if it begins to pickup speed. Depending on the material
being compacted, three or four passes are recommended to achieve the best
compaction.
While a certain amount of moisture in the soil is necessary, excessive
moisture may cause soil particles to stick together and prevent good
compaction. If the soil is extremely wet, allow it to dry somewhat before
compacting.
If the soil is so dry as to create dust clouds while operating the plate, some
moisture should be added to the ground material to improve compaction. This
will also reduce service to the air filter.
For compacting asphalt, use a water tank to wet the asphalt and the underside
of the plate. This will prevent the asphalt material from sticking. Two passes
are usually sufficient to ensure good compaction.
When using the plate on paving stones, attach a pad to the bottom of the plate
to prevent chipping or grinding the stones. A special polyurethane pad
designed for this purpose is available as an optional accessory.
NOTICE: Do not operate the plate on concrete or on extremely hard, dry,
compacted surfaces. The plate will jump rather than vibrate and could damage
both the plate and the engine.
