Operation
and
use
of
the
SCREED
1. Place the screed beam on the rail supports or if you want to use the screed as a free screed,
directly on the freshly poured concrete surface.
2. Now start the engine and allow a three minute warming-up period before setting the throttle
handle to the desired engine speed.
3. After setting the engine speed start moving the screed backwards, the travel-speed depends
on the consistency of the concrete.
4. After the job is finished, remove the Screed from the concrete and switch off the petrol engine.
5. After use, clean the screed according to the instructions described in the maintenance section
of this manual. Place the screed on a dry, clean and stable surface.
6. If you do not expect to use the engine for a long period of time, drain the fuel tank and let the
engine run at idle speed unitl the fuel in the carburetor is used and the engine stops.
NOTE:
Make
sure
to
refill
the
fuel
tank
in
time.
Do
not
let
the
engine
run
so
all
the
fuel
is
used.
This
might
cause
starting
problems.
Prevent
the
screed
from
sinking
into
the
concrete.
After
the
engine
has
been
switched
on,
immediately
move
the
Screed
Easy
backwards.
When
using
a
low
slump
concrete,
move
the
screed
slowly
across
the
surface
of
the
concrete.
When
using
a
high
slump
concrete,
move
the
screed
faster
across
the
surface
of
the
concrete.
When
the
screed
is
used
as
a
wet
screed
it
is
recommended
to
first
compact
the
freshly
poured
concrete
with
a
poker
vibrator
while
at
the
same
time
set
the
height
of
the
floor
by
means
of
a
laser
device.
2.5 Operation
The drive-unit of the screed is started by pulling the recoil-starter of the engine. The
vibrating beam of the screed compacts, levels and smooths freshly poured concrete in one
operation. The screed features a dual purpose beam and can be used for form-to-form
screeding or for free screeding.
By rotating the power-unit 180 degrees, the operator can choose between screeding, using
forms/rails, or free screeding.
