2. Preface
Intended use
Prefab Easy Screed is an easy-to-use vibrating profile for finishing prefab elements. The Prefab Easy Screed consists of
an electrical drive unit with speed regulator mounted on a lightweight profile with 2 carrying handles. The drive unit
has a user friendly clamping system for easy exchanging of beams. The drive unit is available in 230V / 50-60 Hz. On
request available in 115V / 50-60 Hz. The profiles are available in various lengths.
Working
Prefab Easy Screed is used with forms / rails. The profile has a dual purpose and can be used for form-to-form
screeding or wet screeding. By rotating the power-unit 180 degrees the operator can choose which side of the blade
he prefers.

4. Safety
Explanation of the used safety symbols:
Fig. 3: Safety symbols Prefab Easy Screed
ENSURE,THAT ALL SYMBOLS ON THE MACHINE,CAN ALWAYS BE CLEARLY READ.
4.1 Safety aspects
The following safety aspects apply to the machine:
Safety symbols are present on the Prefab Easy Screed
4.2 Safety precautions
The Lievers bullfloats have been developed and tested in accordance with the strict international safety standards.
Before operating these machines, make sure to have read this manual carefully. If you have any questions , do not
hesitate to contact the supplier.
Ensure that you are qualified (familiar with the contents of this manual), to operate and carry out light
maintenance work to the machine.
Wear safety shoes with extra protection (steel caps and anti-slip soles).
Wear a safety helmet and hearing protection.
Wear safety glasses, working gloves which do not conduct electricity and protective clothing.
Ensure that all symbols on the machine, can always be clearly read.
Be careful when lifting and carrying the bullfloat. Do not bend forwards when picking up the machine, but bend
your knees.
When cleaning the machine, ensure that no water or cleaning detergents get into the motorhousing.
When the machine is not being used for longer periods of time, then it must be stored in a dry and clean area.
Regular maintenance of the machine promotes safe operation.
1. Read the instruction manual before using the
machine.
2. Safety glasses, safety helmet and ear
protection compulsory.
3. Working gloves compulsory.
4. Safety shoes with extra protection
compulsory.
5. Before opening remove the plug.
6. Dangerous electric voltage
7. Be careful.

7/18 Operation Manual PREFAB EASY SCREED, revision 2: 29-6-2016
The following safety-aspects specifically apply to those Lievers products which are equipped with an electrical drive
unit:
Place the wires between the electrical source and the work place in such a way, that they cannot be damaged and
your colleagues cannot trip over them.
Do not use the machine in an explosion endangered area.
Check that the electrical source complies with the local valid regulations.
Use an electrical source which is provided with an earth leakage switch or attach a safety transformer between the
electrical mains and the machine.
Regularly check the connections of the supply-cable to the switch.
Ensure that the wall socket and possible connections between the extension leads are protected against dampness.
Do not pull the plug out of the wall socket or extension lead by its lead.
Check the feeder cable’s outercasing and if in use extension lead’s outercasing before you connect the machine to
the electrical mains. The outercasing may not be damaged. Replace the cable if you cannot read the marks on the
outercasing anymore.
Check the machine’s cable-connections before you connect the machine to the electrical mains. The cables must be
properly connected.
Switch off the machine, when the electrical power cuts off. This prevents the machine from starting suddenly when
the electrical power comes on again.
Disconnect the electrical supply to the machine, before you start to clean or maintain the machine.
Ensure that the ventilation slots of the machine are free from dirt and moisture.

5. Use
This chapter describes the use of the Prefab Easy Screed
FOR THE LOCATION AND DESCRIPTION OF THE PREFAB EASY SCREED PARTS,WHICH ARE MENTIONED IN THE TEXT,WE REFER TO FIGURE 2
ON PAGE 4.
5.1. Assembling
When delivered the screed is not ready-for-use. The drive unit and the handles need to be mounted. Required
material: 2 x socket wrench.
1) Mount the drive unit onto the middle of the blade profile with wingbolts. To connect the power-unit to the
blade profile loosen the 3 wingbolts about 8mm. until the front clamping plate no. 3 fits into the collar of the
profile. (see figure 4). Now tighten the 3 wingbolts no.2. Careful: Make sure that the unit is mounted between
the 2 indication arrows, located on the blade.
2) Mount the handles onto both ends of the profile. Use 2 socket wrenches.
3) Attach the cable between the motor and speed regulator onto the profile with cable clamps. Make sure that
the cable is not coming off while finishing the prefab element,

5.2. Use
1. Check that the profile is properly assembled and that the switch is in the OFF- position.
2. Place the machine in the direct vicinity of where you are going to finish the concrete.
3. Put the plug of the drive-unit’s feeder cable in the wall socket.
4. Place the machine on the surface of the freshly poured concrete, and turn the speed regulator slowly to the
required revolutions.
5. Now start to finish the surface.
6. After having finished one lane of concrete, switch of machine by turning the speed regulator’s knob to the
position –MIN-, You will hear a “CLICK”. Tip: If the processed concrete-surface is not smooth enough, repeat
the procedures 4, 5 and 6.
7. Pull the plug of the feeder cable out of the wall socket.
8. Clean the machine with water and a brush.
9. After use, place the Prefab Easy Screed on a dry and stable surface.

10/18 Operation Manual PREFAB EASY SCREED, revision 2: 29-6-2016
6. Maintenance
Although the Prefab Easy Screed only has a few moving parts, regular maintenance promotes a long and
trouble-free life.
WARNING: NEVER USE A HIGH PRESSURE WATER CLEANER TO CLEAN THIS MACHINE WITH AN ELECTRICAL DRIVE UNIT.
WARNING: CUT OFF THE ELECTRICAL SUPPLY TO THE PREFAB EASY SCREED,BEFORE CARRYING OUT ANY MAINTENANCE ACTIVITIES TO
THE MACHINE.
In order to achieve a maximum cooling effect the ventilation openings must stay free from dirt, grease and concrete.
Check them at the end of each working day. If necessary clean them with a brush or a damp cloth.

8. Troubleshooting, repairs
The table below shows the most occurring problems, causes and solutions (Prefab Easy Screed):
PROBLEM
CAUSE
SOLUTION
The machine does not
vibrate in the ‘ON’
position.
Fault in the electrical connections of the
feeder cable.
Check the electrical connections to the
bullfloat, switch, plug and feeder cable for
breakage. Replace the faulty part(s).
The machine does not
vibrate at the required
frequency.
Extensive voltage drop, due to the feeder
cable being too long (longer than 25 m).
Move the electrical source closer to the
working area and use shorter cable.
The electrical motor
rotates irregularly and
makes a lot of noise.
1. the bearings are worn out, and/or
2. an electrical defect in the stator, and/or
3. a break in the feeder cable.
1. replace the bearings, and/or
2. replace the stator, and/or
3. repair or replace the feeder cable.
The connected and
running screed rotates
irregularly and does not
vibrate at the required
frequency.
Insufficient current supply.
Electrical supply via a safety transformer,
check the distributed power from the safety
transformer. Electrical supply via electrical
mains, check the plug connections for
defects. Use an extension lead of a maximum
length of 25 m. with a cross section of 2.5
mm².
The electrical motor
runs irregularly.
The carbon brushes are worn out.
Replace the carbon brushes (replace every 6-
12 months).
