6. MAINTENANCE AND INSPECTION
CLEANING
Keep your machine clean. Cleaning the machine on a regular basis will help detect and solve potential
problems before they cause damage to the machine. Most importantly, check and clean the tool
plate connections, power cord and plugs, vacuum hoses.
CHECK DAILY
After operating the Lavina®13E machine, the operator should conduct a visual inspection of the
machine. Any defect should be solved immediately. Pay attention to power cords, plugs and
vacuum hoses, loose bolt or screws.
Tool holders: Buffers and elastic element are consumables and must be visually checked daily and
replaced if needed. See flanges or discs are mounted locked well in place .
The key lock holders should be also checked.
Check the rubber buffers and fixing of the holders. The flange holding the buffers (Fig.6.1
1 ) and elastic element has to be firmly fixed to the unit. A gap seen there means that there are
loose screws fixing the holder. The screws has to be tightened immediately for safety operation. Working with loose screws on
the holder could also cause bad damages on the machine.
It is very important to check regularly the screws(Fig.6.1 2),that fix the "Quickchange" holder to the safety part, so that
holder will not fly away if the buffers got damaged.“Quickchange” should be clean.
CHECK AND REPLACE AFTER THE FIRST 15 WORKING HOURS
Check the belt tension after 15 hours working with the machine.
For the correct tension, see TROUBLESHOOTING.
CHECK EVERY 200 WORKING HOURS
Every 200 working hours, the operator should inspect all parts of the machine carefully. Most importantly, inspect and clean the tool
plate connections, power cord and plugs, vacuum. Check the guard assembly. Make certain the wheels are clean and rotate properly.
Inspect the control buttons. If there are defective control parts, they should be replaced immediately. Replace worn vacuum- and
water hoses. Carefully inspect the seal rings and bearings of the grinding units, and replace any showing signs of excessive wear.
For more information, refer to chapter troubleshooting below.
CHECK EVERY 500 WORKING HOURS
Besides the checks of 200 working hours, open up the bottom cover like described in chapter “TROUBLE SHOOTING REPLACING BELT
Check if sealers, belt and bearings are in good condition, change if needed. Beware by tensioning the belt not to “over tension”; the
belt will never regain his original tension.
VACUUM
As stated previously, frequently check hoses and other parts for clogging.
MECHANICAL PARTS
Parts such as the belt, seal rings, cap rings, spiders and buffers and guard assembly are subject to wear and should be replaced as
needed.
ELECTRICAL SYSTEM
Dust should not enter the control box as it will destroy the contacts.
Remove (blow out) any dust present.

7. TROUBLESHOOTING
INDEX OF PROBLEMS AND SOLUTIONS
7.1 REPLACING POWER CORD AND PLUGS
When replacing the power cord or plugs always use cords and plugs with specifications as the original ones.
Never use lower quality or different type cord and plugs.
In addition, take into consideration the distance of the appliance from the electrical source. The greater the distance, the greater
the resistance and the less current that will be available at the other end; there will be a voltage drop and the inverter will sign
alarm mode. This can also happen if several machines are working on the same line or when the generator is underrated. In general
our standard power cable can be doubled in length; if longer lengths are needed you have to replace all the cables with bigger gage
rated cables for the length and amperage.
7.2 DISMOUNTING TOOL HOLDER TO CHANGING V-RINGS
To check or replace the buffers and
the elastic elements, the tool holders
have to be dismounted.
You will need a 13mm deep metric
socket with an outside diameter of no
more than 3/4in to unscrew the four
bolts (Fig.7.2.1) and remove the
holder (Fig.7.2.2) and adaptor
(Fig.7.2.3). When the tool holder is
dismounted, you can change the
sealers (V-Ring). Mount the V-Ring
with the smallest lip of the V to the
inside (Fig.7.2.4) - simply push the V-
Ring so the top is on the same level
as the pulley top (Fig.7.2.5). Then
take the adaptor and push the V-Ring
down with the adaptor. The lowest lip
of the V-Ring should only barely
touch its gliding surface. Mount the
adaptor and the Holder on top
(Fig.7.2.6). Always use the original
bolts. Do not push the V-ring down
with fingers.
7.3 DISASSEMBLING AND MOUNTING TOOL HOLDER TO CHANGE BUFFERS AND ELASTIC ELEMENT
When the TOOL HOLDER is disassembled you can change defective parts –elastic element, buffers, etc.
Lift the locking pin (Fig.7.3.1) to dismount the retaining washer (Fig.7.3.2). Take out the screws on the buffers and the nuts of the
elastic element (Fig.7.3.3;Fig.7.3.4). Remove the elastic element from the QC plate (Fig.7.3.5). While the holder is dismounted
(Fig.7.3.6;Fig.7.3.7) clean the parts and replace the defective with new ones. Assemble the holder with new buffers with new screws
and new elastic element. Put the retaining washer (Fig.7.3.8) and push the locking pin (Fig.7.3.9). This will prevent the fall of the
washer when mounting the holder on the machine.

Make sure the four bolts holding the adaptor
(Fig.7.3.12) are reliably tighten. Mount the
holder on the machine using the same socket
as mentioned in 7.2 (Fig.7.3.10;Fig.7.3.11). The
retaining washer fits into the central hole C of
adaptor and the four bolts into the thread
holes Т (Fig.7.3.12). The holder is centered on
the outside diameter of the adaptor. Ensure
the connection of the holder on the forehead
of the adaptor and then tight evenly the four
bolts. Tightening force of the bolts has to be
22...25N.m(16...18 ft/lbs). Mounting the
holder without retaining washer (Fig.7.3.2) is
INADMISSIBLE because the security system
preventing the separation of part of the
holder in case of broken buffers and elastic
element will not function!
You can change the butterfly of the holder
without dismounting the holder of the
machine.
Fig.7.3.13 is 3-d section view of the holder,
showing its parts. The numbering is the same
as in Spare parts.

7.4 TENSIONING THE BELTS
PLEASE MAKE SURE YOU CHECK THE TENSION OF THE BELT AFTER THE FIRST 15 HOURS OF OPERATION
If the operator notices, the grinding spindle is turning irregular or noisy or in the worse case, the grinding spindle does not
turn although the motor turns. It is recommended to check the belts.
ATTENTION: NEVER “OVER” TENSION THE BELT, THE BELT WILL BE DISTROYED AND IT WILL NEVER RECOVER ITS ORIGINAL
TENSION
Remove the revision cover (Figure 7.4.1) and turn the screw (Figure 7.4.3) clockwise to tight the belt. The tightening force
of one belt is 173 N measured by OPTIKRIK 1 ( Figure 7.4.2) .
7.5 CHANGING THE BELT
Loosen the screws on the working
plate (Figure 7.5.1) and remove it
from the working part (Figure 7.5.2).
Release the sucker using the screws on its inside peripheral part (Figure 7.5.3) and remove it along with the removable guard.
Remove the V-Ring and Felt-Ring as described in 7.2 . Remove the front cover by loosening the screws (Figure 7.5.4) and the
revision cover by loosening the screws (Figure 7.5.5). By the tightening bolt (Figure 7.5.6) move the motor forward and release
the two belts. Put the new belts and tighten them. The Static Belt Tension should be 225 N with a new belt, only 173 N with
a used one. It is recommended to use an OPTIKRIK 1 Tension Gauge. The assembly is made in reverse order.
