SAFETY WARNINGS
!
CAUTION
During the working phases pay
particular
attention
to
possible
control loss by the trowel (for
example due to the presence of too
much water on the working surface).
Check
that
there
are
no
obstructions or obstacles on the
work surface or protruding parts
that block blade rotation.
!
CAUTION
The user must be aware that the
moving parts are dangerous;
Therefore, to prevent damage, it
is important that you follow the
instructions provided in this
manual.
Carefully read the instructions
and recommendations included
in this manual.
IMPORTANT!
For
stability
reasons
it
is
recommended to use the machine
on a very stable flat and horizontal
place. Do not use the machine on
slopes greater than 4%-5%.
5.2
SURFACE PREPARATION
IMPORTANT!
Consider carefully that the trowel
does NOT improve the flatness of
a floor which has been badly
propped up or levelled.
We recommend the use of a mechanical
vibrating screed or manual screed for striking
off the floor surface. This preliminary
operation will provide a good compaction of
the concrete floor and consequently an ideal
surface for troweling and finishing will be
obtained.
5.3
TROWELING STAGE
IMPORTANT!
Before
starting
the
troweling
operation, make sure that the feather
edge discs have been properly
mounted on the blades.
The floor will be ready for the first troweling
when the footprint of the shoe heel while
walking is about 2-3 mm deep in the
concrete.
During the troweling stage the feather edge
discs must not jump on the surface; this
phenomenon may be due to dirt nestled
between the blades and the feather edge
disc.
If necessary stop the trowel and clean it as
described in the next chapter.
The
troweling
intervals
depend
on
environmental
factors,
specifically:
the
temperature and weather conditions. On
average ten minutes of troweling are enough
for 250-300 square meters.
After each operation, shut down the
engine.
!
CAUTION
Use a special lifting gear to move it.
In case you need to lift it more than
100 cm from the ground, preventively
remove the feather edge disc as
described in PAR. 6.2.3.
Never leave the trowel stopped with its
engine on, especially at the troweling stage
when the concrete is still fresh.
Be careful
not to work continuously in the same spot
when the concrete is still fresh, as it may
cause damage to floor flatness.
5.4
FINISHING STAGE
After you have performed troweling:
●
Remove the feather edge disc from
the blades and clean the blade-holding
disk from the cement deposited during a
troweling stage (make use of P.P.E).
●
Turn the blade-lifting lever (as shown
in fig. 5.1) clockwise up to give an
inclination to blades of about 1 cm. to
perform the first troweling;
