1.2 Machine Description and Intended Use

This machine is a vibratory concrete screed. The Wacker Neuson Wet Screed
consists of a gasoline engine, a fuel tank, a metal blade, an eccentric weight
positioned at the center of the metal blade, and a control handle. The gasoline
engine spins the eccentric weight through a drive shaft, producing vibrations that
travel the length of the metal blade. The operator uses the control handle to pull the
machine across uncured concrete.

This machine is intended to be used for striking off uncured concrete slabs with or
without the support of grade stakes or forms.

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

■ Engaging the screed when not on uncured concrete

■ Operating the machine on non-compactable surfaces, such as asphalt or cured

concrete

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

■ Chemical burns from the curing concrete

■ Fire hazards from improper refueling techniques

■ Fuel and its fumes, fuel spillage from improper lifting technique

■ Personal injury from improper lifting techniques or operating techniques

■ Excessive vibration by holding the blade

■ walk backwards while pulling the screed across the wet concrete

wc_tx003253gb_FM10.fm

23

Operation P 35A

4.4 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.

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.

4.5 Before Starting

Read and understand safety and operating instructions at beginning of this manual.

Check:

■ Oil level in engine

■ Fuel level

■ Condition of air cleaner

■ Tightness of external fasteners

■ Condition of fuel lines

Adjust handles for operator’s comfort

CAUTION

Pinch hazard.

► Make sure all hardware is tightened before use and be aware of pinch points

during handle adjustments.

4.8 Operation

Procedure

Perform the procedure below to perform a typical screeding of concrete.

1. Establish wet pads for wet screed guidance. Place wet pads (a) in strips no less
than 0.6m (2.0 ft) wide.

d

Note: Hand tools such as magnesium floats are used in conjunction with a laser

receiver, transit level, or grade stakes to establish the proper elevation of the pads.

2. Use a float to strike off or build up the level of the fresh concrete to the desired
grade. This is usually marked with an “X” (b) to signal the screed operator that
grade has been established. A minimum of two areas should be marked per
length of screed blade used to strike the entire pad.

3. Place the blade on the pad and strike-off perpendicular to the strip axis (c). Use
the marked pads as elevation guides.

4. Place concrete between the strips (d) and use them as “wet forms” for the rest
of the placement. Strike-off at this point will be parallel to the axis of the initial
wet pads of concrete.

This procedure continues on the next page.

26

wc_tx003253gb_FM10.fm

P 35A Operation

Continued from the previous page.

Note: Screeding MUST be complete before any excess moisture or bleed water is
present on the surface, and before the strips have taken an initial set.

5. Start the engine and move the throttle forward one-half to three-quarters. This
increases the engine speed to approximately 6000–7000 rpm which is
appropriate for most screeding applications.

6. Pull the screed across the concrete to perform the strike-off. A creamy liquid
should form around the edges of the screed blade as the concrete is leveled.

NOTICE: Operating the screed at continuous full throttle is not recommended.
Prolonged operation of the engine at high speed creates excessive vibration that
cannot be absorbed by the concrete. This can result in:

■ increased machine vibration

■ increased handle vibration

■ premature failure of the power unit

■ premature failure of the exciter

■ accelerated drive shaft wear

To prolong screed life, use the lowest possible throttle and exciter settings that
produce an acceptable surface finish. The proper engine speed for a given exciter
setting will produce a smooth concrete surface and limit vibration transmitted to the
machine and handles.

Troubleshooting

Follow the recommendations below if a creamy liquid does not appear while
striking off the concrete.

■ Increase engine speed slightly.

■ Increase the exciter setting one position at a time to properly vibrate the

concrete. See Exciter Adjustment.

4.9 Exciter Adjustment

Overview

Procedure

Proper operation of the screed produces a creamy liquid around the blade during
strike-off. If a creamy liquid does not form at the standard throttle range of one-half
to three-quarters speed (6000–7000 rpm), or with slight speed increases, then
adjust the exciter.

Perform the procedure below to adjust the exciter.

1. Remove the 4 screws (a) mounting the blade to the power unit.

2. Remove the 3 screws mounting the eccentric housing (b).

3. Using a 1/4-inch Allen wrench, loosen the screw (c) holding the adjustable
eccentric weight in place.

4. The screed eccentric is preset at the factory to Position 2 as shown. Rotate the
exciter to the right for less vibration, or to the left for more vibration.

Note: The maximum vibration exciter setting is Position 1. The minimum exciter
vibration setting is Position 3.

5. Reassemble components and tighten all hardware.

Vibration
specifications

The required sound specification, Paragraph 1.7.4.2.u of 2006/42/EC Machinery
Directive, is:

 the sound pressure level at operator’s location (L
 the guaranteed sound power level (L

): 97 dB(A)

WA

): 85 dB(A)

pA

These sound values were determined according to ISO 3744 for the sound power
level (L

) and ISO 6081 for the sound pressure level (LpA) at the operator’s

WA

location. Data was collected from a technically comparable machine under
laboratory conditions.

The operator of this machine should expect to be exposed to vibration when using
the machine within its normally intended function.

ISO 5349 Part 1 Annex F states, “The vibration characteristics of a vibrating tool
can be highly variable. It is therefore important that the range of vibration
conditions associated with different workpieces, materials, working conditions,
methods of use of the tool, and exposure duration patterns be reported.”

 The average hand and arm vibration (HAV) value obtained for the entire

operating rpm range is 4.7 m/s

 The maximum hand and arm vibration value obtained within the entire operating

rpm range is 6.1 m/s

 The minimum hand and arm vibration value obtained within the entire operating

rpm range is 3.5 m/s

 Operating the machine in the recommended RPM range of 6000 to 7000 rpm

Uncertainties

Products are tested for hand/arm vibration level in accordance with ISO 5349 Part
1 and ISO 8662 Part 1. The results are in compliance with the limit and action
vibration values (hand/arm and whole body) as specified in European directive
2002/44/EC.

Hand-transmitted vibration was measured per ISO 5349-1. This measurement
includes an uncertainty of 1.5 m/s
