General Safety Instructions
■
When operating the Wet Screed wear ear protection, safety
glasses, a safety helmet, gloves which do not conduct
electricity and protective clothing.
■
Ensure that all symbols on the Wet Screed — can always
be clearly read.
■
Regularly check the Wet Screed’s connections.
■
When cleaning the Wet Screed, ensure that no water or
cleaning detergents, under high pressure, get into the
motor housing or plug connections.
■
When the Wet Screed is not being used for long periods of
time, then it must be store in a dry and clean area.
Important Safety Checks for the electrical Wet Screed
■
Check the feeder cable and extension cords outer casing
before you connect the Wet Screed to the electrical mains.
■
Check the feeder cable’s attachment on
the bullfloat, before you connect the Wet
Screed to the electrical mains. The cable must
be correctly attached to the bullfloat .
■
Ensure that the feeder cable does not graze
past any sharp objects.
■
The use of extension cords are permitted, if they are
completely watertight.
■
Switch the Wet Screed “off” when the
electrical power cuts off.This prevents the
Bullfloat from starting suddenly when the
electrical power comes on again.
■
Check the feeder cable and extension cord’s attachments
regularly. When the Wet Screed is in operation, the plugs
can loosen due to the vibrations.
SAFETY INSTRUCTIONS
■
Connect the Wet Screed to an alternating voltage source of
110VAC, which is provided with a ground switch, with a
frequency of 50-60 Hz.
■
Check that the ventilation openings in the motor housing
are free from dirt and moisture.
■
Regularly check the connections of the feeder cable to

A Wet Screed is a strike-off method where the blade rides on
concrete rather than form or rails. Level bases are established
in long strip parallel to the forms. Once completed the contractor
is then free to "wet screed" the concrete in between the two
bases.
This section describes the operation of the K 200 Wet
Screed.
Tip: For the location and description of the Wet Screed’s parts,
which are mentioned in the text, refer to the illustration figure
(page. 9): What is a Wet Screed.
How to assemble the K 200 Wet Screed.
When delivered the Wet Screed is not ready for use.You only
have to carry out the following procedures to assemble them:
1.Connect the switch (an electronic speed regulator, or a
gas throttle), to the operating handle by means of the
bracket and the butterfly nut. Now lock the bracket by
tightning the butterfly nut. (Fig. No. 2.0)
2.Stick the operating handle into the shaft of the motor unit
frame.Make sure that the operating handle is locked
properly.
Operation and use of the Wet Screed
This section describes how to operate and use the Wet
Screed.In the text are numbers in brackets. These numbers are
position numbers and they correspond to the numbers in the
parts list of the corresponding figures.
Careful: Read the safety instructions before you switch
on the apparatus.
Careful: Prevent the Wet Screed, from sinking into the
concrete. After the motor has been switched on, immediately
move the Wet Screed backwards.
Tip: Before the Wet Screed is brought into action, first compact
the freshly poured concrete floor with a poker-vibrator while at
the same time adjust the height of the floor by means of a
laser device.
Tip: Pour concrete lanes of approx. 2m wide and approx. 15 m
long. You can finish this surface in one pass without any problem.
