DUOSCREED
Operation manual
2.2 Operation and use of the DuoScreed
A.
Place the DuoScreed profile on the rail supports or in case you want to use the DuoScreed
as a wet screed, directly on the freshly poured concrete surface.
Careful: before starting the petrol engine read the enclosed operation
instructions
carefully.
Make sure before starting that the ON-OFF switch is in the ON position!
B.
Now start the engine and allow a three minute warming-up period before setting the throttle
handle to the desired engine speed.
C.
After setting the engine speed start moving the DuoScreed backwards, the travelspeed
depends on the consistency of the concrete.
D.
If the DuoScreed vibrates to strong the centrifugal force needs to be reduced. This is done
by first removing the vibrator’s protection cover and adjust the excentrical weights to a
lower centrifugal force. (See figure 6) A well adjusted screeder will create a level, smooth
and shining surface.
E.
After the job is finished, remove the DuoScreed from the concrete lane and switch off the
petrol
engine.
D.
After use, clean the DuoScreed according to the instructions described in chapter 4 of this
manuel. Place the DuoScreed on a dry, clean and stable surface.
F.
If you do not expect to use the engine for a long period of time, drain the fuel tank with fuel
and let the engine run at idle speed until the fuel in the carburator is used and the engine
stops.
Please observe the following instructions:
1. make sure to refill the fuel tank in time. Do not let the engine run until all the fuel
is used. This might cause starting problems.
2. prevent the DuoScreed of sinking into the concrete. After the engine has been switched
on, immediately move the DuoScreed backwards.
3. When using a low slump concrete, move the DuoScreed slowly across the surface of the
concrete. When using a high slump concrete, move the DuoScreed faster across the surface
of the concrete.
4. In case the DuoScreed 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.
Figure 6 Various positions of the vibrator.
How to adjust the centrifugal force: CAREFULL:SWITCH OFF ENGINE FIRST.
1. Remove the protecting cover of the vibrator by loosening the springknob.
2. Now loosen the wingbolt of the vibrator and adjust the vibrator in accordance with the
indicated positions in the drawing. Retighten the wingbolt and refix the protection cover.
