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, and 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

Operation P 35A

18 wc_tx000781gb.fm

3.8 Operation

See Graphic: wc_gr001074

Procedure

Follow the procedure below to perform a typical screeding of

concrete.

3.8.1 Establish wet pads for wet screed guidance. Place wet pads (a) in

strips no less than 0.6m (2.0 ft) wide.

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.

3.8.2 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.

3.8.3 Place the blade on the pad and strike-off perpendicular to the strip

axis (c). Use the marked pads as elevation guides.

3.8.4 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 (e).

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.

3.8.5 Start the engine and move the throttle forward one quarter to halfway.

This increases the engine speed to approximately 5000–6000 rpm

which is appropriate for most screeding applications.

3.8.6 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

P 35A Operation

wc_tx000781gb.fm 19

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.
