ROUTINE AND ADDITIONAL
MAINTENANCE
6.2.1
Blades replacement
Check the state of wear of the blades
or if they have been damaged or bent. To
replace blades perform the following steps:
•
Clean the trowel from any processing
residue;
•
Remove the attachment bolts (hex
head 6x35) of the blades on each arm
of the trowel machine (2 for each arm)
(FIG. 6.2) by means of a suitable tool
and long enough to do this on the
ground with assembled machine;
•
Fit the new blades fixing bolts with their
split rings.
6.2.2
Unlocking of blades holding
arms and pressure plate
As indicated in para. 6.3 in the event that
the tilt control does not work, this
drawback may be due to a blockage of the
blades-holding arms or of the pressure plate.
Unlocking of blades holding arms and
pressure plate and replacement of blades
holding arms if necessary.
To unblock the blades and the pressure plate
refer to the dealer (authorized workshop).
6.2.3
Trowel disc replacement
The trowel disc is subject to wear which
manifests itself through an enlargement of the
same.
If, as a result of a visual inspection, this
happens, replace the disc.
Proceed as follows:
•
Unhook the blades out of the
hooking tabs (the tabs on the
trowel disc are 2 or 4 depending on the
number of blades), slightly raising the
machine by leveraging the two hooks
as shown in FIG. 6.3;
•
The trowel disc remains on the ground
once released from the blades (Fig.
6.3.1-2);
.
•
Perform disc replacement and
reposition the machine on the new disc
by moving it from above with adequate
lifting body;
•
Replace the tabs of the new disc to the
blades, proceeding backwards with
respect to the coupling maneuver.
IMPORTANT!
For correct operation of the trowel
machine, in case of breakage or
damage of one or more blades,
replace all of them.
!
ATTENTION
Use an appropriate lifting body to
handle the trowel. During the
cleaning of the blades and the
blade disc to be carried out with
the blades fitted, it is compulsory
to wear the appropriate PPE
(protective gloves with mechanical
agents and safety shoes).
