1.1 Laws Pertaining to Spark Arresters
Notice: State Health Safety Codes and Public Resources Codes
specify that in certain locations spark arresters be used on internal
combustion engines that use hydrocarbon fuels. A spark arrester is a
device designed to prevent accidental discharge of sparks or flames
from the engine exhaust. Spark arresters are qualified and rated by
the United States Forest Service for this purpose.
In order to comply with local laws regarding spark arresters, consult
the engine distributor or the local Health and Safety Administrator.

1.2 Operating Safety
Familiarity and proper training are required for the safe operation of the
machine. Machines operated improperly or by untrained personnel
can be hazardous. Read the operating instructions contained in this
manual and the engine manual, and familiarize yourself with the
location and proper use of all controls. Inexperienced operators should
receive instruction from someone familiar with the machine before
being allowed to operate it.
1.2.1 Do not allow anyone to operate this equipment without proper training.
People operating this equipment must be familiar with the risks and
hazards associated with it.
1.2.2 Do not touch the engine or muffler while the engine is on or
immediately after it has been turned off. These areas get hot and may
cause burns.
1.2.3 Do not use accessories or attachments that are not recommended by
Wacker Neuson. Damage to equipment and injury to the user may
result.
1.2.4 NEVER operate the machine with the beltguard missing. Exposed
drive belt and pulleys create potentially dangerous hazards that can
cause serious injuries.
1.2.5 Never leave the machine running unattended.
1.2.6 Be sure operator is familiar with proper safety precautions and
operation techniques before using machine.
1.2.7 Always wear protective clothing appropriate to the job site when
operating the machine.
1.2.8 Wear hearing protection when operating equipment.
1.2.9 Close fuel valve on engines equipped with one when machine is not
being operated.
1.2.10 Store the machine properly when it is not being used. The machine
should be stored in a clean, dry location out of the reach of children.
1.2.11 Always operate machine with all safety devices and guards in place
and in working order. Do not modify or defeat safety devices. Do not
operate machine if any safety devices or guards are missing or
inoperative.
1.2.12 Read, understand, and follow procedures in the Operator’s Manual
before attempting to operate the machine.
WARNING

1.3 Operator Safety while using Internal Combustion Engines
Internal combustion engines present special hazards during operation
and fueling. Read and follow the warning instructions in the engine
owner’s manual and the safety guidelines below. Failure to follow the
warnings and safety standards could result in severe injury or death.
1.3.1 DO NOT run the machine indoors or in an enclosed area such as a
deep trench unless adequate ventilation, through such items as
exhaust fans or hoses, is provided. Exhaust gas from the engine
contains poisonous carbon monoxide gas; exposure to carbon
monoxide can cause loss of consciousness and may lead to death.
1.3.2 Do not smoke while operating the machine.
1.3.3 Do not smoke when refueling the engine.
1.3.4 Do not refuel a hot or running engine.
1.3.5 Do not refuel the engine near an open flame.
1.3.6 Do not spill fuel when refueling the engine.
1.3.7 Do not run the engine near open flames.
1.3.8 Refill the fuel tank in a well-ventilated area.
1.3.9 Replace the fuel tank cap after refueling.
1.3.10 ALWAYS check the fuel lines and the fuel tank for leaks and cracks
before starting the engine. Do not run the machine if fuel leaks are
present or the fuel lines are loose.

1.4 Service Safety
A poorly maintained machine can become a safety hazard! In order
for the machine to operate safely and properly over a long period of
time, periodic maintenance and occasional repairs are necessary.
1.4.1 Do not attempt to clean or service the machine while it is running.
Rotating parts can cause severe injury.
1.4.2 Do not crank a flooded engine with the spark plug removed on
gasoline-powered engines. Fuel trapped in the cylinder will squirt out
the spark plug opening.
1.4.3 Do not test for spark on gasoline-powered engines if the engine is
flooded or the smell of gasoline is present. A stray spark could ignite
the fumes.
1.4.4 Do not use gasoline or other types of fuels or flammable solvents to
clean parts, especially in enclosed areas. Fumes from fuels and
solvents can become explosive.
1.4.5 Keep the area around the muffler free of debris such as leaves, paper,
cartons, etc. A hot muffler could ignite the debris and start a fire.
1.4.6 Replace worn or damaged components with spare parts designed and
recommended by Wacker Neuson Corporation.
1.4.7 Disconnect the spark plug on machines equipped with gasoline
engines, before servicing, to avoid accidental start-up.
1.4.8 Keep the machine clean and labels legible. Replace all missing and
hard-to-read labels. Labels provide important operating instructions
and warn of dangers and hazards.

The required sound specification, Paragraph 1.7.4.f of 89/392/EEC
Machinery Directive, is:
• The guaranteed sound power level (LWA) = 108 dB(A).
• The sound pressure level at operator’s location (LpA) = 97 dB(A).
These sound values were determined according to ISO 3744 for the
sound power level (LWA) and ISO 6081 for the sound pressure level
(LpA) at the operator’s location.
The weighted effective acceleration value, determined according to
EN ISO 5349, is approximately 4.5 m/s2.
The sound and vibration measurements were obtained with the
machine operating on crushed gravel at nominal engine speed.

3. Operation
3.1 Recommended Fuel
The engine requires regular grade unleaded gasoline. Use only fresh,
clean gasoline. Gasoline containing water or dirt will damage fuel
system. Consult engine owner’s manual for complete fuel
specifications.
3.2 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.
This plate is not recommended for compacting cohesive soils with a
heavy clay content.
3.3 Before Starting
3.3.1 Read and understand the safety and operating instructions at the
beginning of this manual.
3.3.2 Check:
• Oil level in the engine
• Fuel level
• Condition of the air cleaner
• Tightness of the external fasteners
• Condition of the fuel lines

VP 2050A/AW Operation
wpm_tx001097gb.fm 17
3.4 To Start
See Graphic: wc_gr000014
3.4.1 Open fuel valve by moving lever to the right (a1).
Note: If engine is cold, move choke lever to close position (b1). If
engine is hot, set choke to open position (b2).
3.4.2 Turn engine switch to “ON” (e1).
3.4.3 Open throttle by moving it slightly to left (d1).
3.4.4 Pull starter rope (c).
Note: If the oil level in the engine is low, the engine will not start. If this
happens, add oil to engine. Some engines are equipped with an oil
alert light (f) that will come on while pulling the starter rope.
3.4.5 Open choke as engine warms (b2).
3.4.6 Open throttle fully to operate.
3.5 To Stop
See Graphic: wc_gr000014
3.5.1 Reduce engine RPM to idle by moving throttle completely to right (d2).
3.5.2 Turn engine switch to “OFF” (e2).
3.5.3 Close fuel valve by moving lever to the left (a2).

Operation VP 2050A/AW
wpm_tx001097gb.fm 18
3.6 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 pick up 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 soil is extremely wet, allow it to dry somewhat before
compacting.
If soil is so dry as to create dust clouds while operating 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 plate. This will prevent asphalt material from sticking.
Two passes are usually sufficent 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 surface of 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.
