ROUTINE AND ADDITIONAL
MAINTENANCE
6.2.1
Replacement of
blades
Check the state of wear of the blades or if
they have been damaged or bent. To
carry out the replacement of the blades
proceed as follows:
●
Clean the trowel from any processing
residues;
●
To perform this operation you must
first lift the machine on one side, while
keeping the support on the other side,
by means of a special lifting gear as
indicated in PAR. 3.2.
●
Remove the fixing bolts (hexagon
head screws 6x35) of the blades on
each trowel arm (2 for each arm) (fig
6.1) by means of a suitable tool
(screwdriver
or
hexagonal-head
wrench, size 13).
●
Assemble the new blades fixing the
screws with their split washers.
●
Repeat the operation on the other
side of the machine.
IMPORTANT!
For a correct operation of the
trowel, in the event breakage or
damage of one or more blades,
replace all the blades.
6.2.2
Unlocking of blade holder
arms and of cover plate
If the blade-lifting control does not work, this
may be due to blockage of blade-holding
arms or of the cover plate.
Unlocking of the blade-holding arms and
of the cover plate or any replacement of
the blade-holding arms.
To unlock the blades and the cover plate
refer to the reseller (authorized dealer).
6.2.3
Feather edge disc
replacement
IMPORTANT!
Before performing the operation
clean the blades from cement
residues.
Use
cut-resistant
gloves.
Feather edge disks are subject to wear that is
indicated by their expansion. If, as a result of
a visual inspection, this is the case, replace
any damaged disk or disks.
Do as follows:
At the bench or on the ground lift the machine
as prescribed in PAR. 3.2
●
On the ground unhook the blades from
the clasps (there are 2 or 4 clasps on the
feather edge disc depending on the
number of blades), slightly lifting the
machine (approximately 10 cm) through
the four hooks supplied (fig 6.1).
●
The feather edge disc remains on the
ground once released from the
blades (fig. 6.2.1).
●
Replace the disk or disks, inserting
the feather edge discs on the blades,
checking the direction of rotation.
●
After the installation of new discs
replace the troweling machine on the
ground or on the bench.
