2.1 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.

2.4 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.
WARNING
2.4.1 Do not attempt to clean or service the machine while it is running.
Rotating parts can cause severe injury.
2.4.2 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.
2.4.3 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.
2.4.4 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.
2.4.5 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.
2.4.6 Replace worn or damaged components with spare parts designed and
approved by Wacker Neuson.
2.4.7 Disconnect the spark plug on machines equipped with gasoline
engines, before servicing, to avoid accidental start-up.
2.4.8 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.

4. Operation
4.1 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.
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.
The following is the Wacker Neuson approved percentage of oxygenates:
ETHANOL - (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, E20, 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 mentioned above are not covered under
warranty.
4.2 Before Starting
4.2.1 Read and understand the safety and operating instructions at the
beginning of this manual.
4.2.2 Check:
• Oil level in the engine
• Fuel level
• Condition of the air cleaner
• Tightness of the external fasteners
• Condition of the fuel lines

4.3 To Start
See Graphic: wc_gr000014
4.3.1 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).
4.3.2 Turn engine switch to “ON” (e1).
4.3.3 Open throttle by moving it slightly to left (d1).
4.3.4 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.
4.3.5 Open choke as engine warms (b2).
4.3.6 Open throttle fully to operate.
4.4 To Stop
See Graphic: wc_gr000014
4.4.1 Reduce engine RPM to idle by moving throttle completely to right (d2).
4.4.2 Turn engine switch to “OFF” (e2).
4.4.3 Close fuel valve by moving lever to the left (a2).

Operation WP 1550A/AW
4.5 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.
wpm_tx001131gb.fm 22
WP 1550A/AW Operation
4.6 Operation
See Graphic: wpmgr006016
Run engine at full throttle and allow plate to pull itself along at its
normal speed. When operating on an incline it may be necessary to
assist plate by pushing it forward slightly. 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, open water tank valve (a1) to wet asphalt and
underside of plate. This will prevent asphalt material from sticking. Two
or three passes are usually sufficent to ensure good compaction.
When using plate on paving stones, attach a pad to the bottom of the
plate to prevent chipping or grinding surface of the stones. A special
urethane pad designed for this purpose is available as an optional
accessory.
NOTICE: DO NOT operate plate on concrete or on extremely hard,
dry, compacted surfaces. The plate will jump rather than vibrate and
could damage both plate and engine.

5.1 Maintaining the Emission Control System
Normal maintenance, replacement, or repair of emission control devices and systems may be
performed by any repair establishment or individual; however, warranty repairs must be performed
by a dealer/service center authorized by Wacker Neuson. The use of service parts that are not
equivalent in performance and durability to authorized parts may impair the effectiveness of the
emission control system and may have a bearing on the outcome of a warranty claim.

5.3 Cleaning Plate
Clean plate after use to remove dirt, stones, and mud caught under the
engine console. If plate is being used in a dusty area, check engine
cylinder cooling fins for heavy dirt accumulation. Keep engine cylinder
fins clean to prevent engine from overheating.
5.4 Drive Belt
See Graphic: wc_gr000077
On new machines or after installing a new belt, check belt tension after
first 20 hours of operation. Check and adjust belt every 50 hours
thereafter.
To change the belt:
5.4.1 Remove the beltguard and remove the four hex nuts (a) holding pulley
halves (b) together. Remove outer pulley half and remove belt.
5.4.2 Install new belt on pulley and secure pulley halves together with hex
nuts. Adjust tension on belt by adding or removing spacers (c)
between pulley halves. The fewer spacers used between pulley
halves, the tighter the belt will be. Three spacers with new Wacker
belts should provide the correct tension. Belt deflection should be 6–
10 mm, checked half way between the clutch pulley and the exciter
pulley (d). Place unused spacers on outside of pulley.
5.4.3 Replace beltguard.
