7. 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 and water tank.
After operating the Lavina 16-X-E 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. Check that flanges or discs are mounted
locked well in place. The key lock holders (butterflies) should be also checked.
Check the rubber buffers and fixing of the holders. The flange holding the buffers
(Fig.7.1-1) has to be firmly fixed to the unit. A gap seen here indicates loose screws
fixing the holder. The screws have to be tightened immediately for safe operation.
Working with loose screws on the holder could also cause damages to the machine.
Tightening force of the screws should be 25...30N.m (18...22 lbf.ft).
It is very important to check regularly the screws (Fig.7.1-2) that fix the
"Quickchange" holder to the safety part, so that holder will not fly away if the buffers
got damaged.
head and feeling the resistance of the moving pulleys, if the belt slips, tension immediately as described in the
chapter 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 hoses and water tank. 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.
Check the tension of the belt and to tighten if necessary. For the correct tension, see TROUBLESHOOTING.
Dismount the tool holders (See Troubleshooting) replace all parts (Elastic element
rings) showing damage or wear.
Open the inspection cover on the motor base to check of the planetary driving belt, by moving the main head
the belt should not slip on the planetary pulley and drive the pulleys.
CHECK EVERY 400 WORKING HOURS
In addition to checks made every 200 working hours, replace sealer and V-rings as described in
SHOOTING - REPLACING BELT AND PULLEY UNITS . Check if belts and bearings are in good
condition, change if needed. Be wary when tensioning the belt to not ; the belt will never regain
its original tension.
VACUUM
As stated previously, frequently check hoses and other parts for clogging.
WATER LEAKS
Replace any leaking parts immediately as the water could damage your machine.
MECHANICAL PARTS
Parts such as the belts, 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.

8. TROUBLESHOOTING
INDEX OF PROBLEMS AND SOLUTIONS
8.1 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.
8.2 DISMOUNTING AND MOUNTING TOOL HOLDER TO CHANGING SEALERS
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.8.2.1) and remove the holder (Fig.8.2.2)
By loosening four Hex cap flange bolts (Fig.8.2.3), the adaptor comes loose. When the tool holder is
dismounted, you can change the sealers (Fig.8.2.4).
Take out Adaptor with the sealer and change it (Fig.8.2.5).
8.3 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.8.3.1) to dismount the retaining washer (Fig.8.3.2). Take out the screws on the buffers
and the nuts of the elastic element (Fig.8.3.3;Fig.8.3.4). Remove the elastic element from the QC plate
(Fig.8.3.5). While the holder is dismounted (Fig.8.3.6;Fig.8.3.7) 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.8.3.8) and push the locking pin (Fig.8.3.9). This will prevent the washer from falling while
mounting the holder to the machine.
Make sure the four bolts holding the adaptor (Fig.8.3.12) are reliably tightened. Mount the holder on the
machine using the same socket as in 8.2 (Fig.8.3.10; Fig.8.3.11). The retaining washer fits into the central
hole C of adaptor and the four bolts into the thread holes (Fig.8.3.12). The holder is centered on the
outside diameter of the adaptor. Ensure the holder is properly connected to the plate of the adaptor and
then tight evenly the four bolts. Tightening force on the bolts has to be 22...25N.m(16...18 lbf.ft). Mounting
the holder without the retaining washer (Fig.8.3.2) is INADMISSIBLE because the security system
preventing the separation 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.

8.4.1), water-(Fig. 8.4.2) (Fig. 8.4.3) and vacuum tubes. Remove the two pins from the brackets (Fig. 8.4.3).
Dismount the top cover (Fig. 8.4.4), (Fig. 8.4.5).
8.5 TENSIONING USED PLANETARY BELT
If there is a loss of speed in the planetary motion, it is possible to re-tension a used planetary belt by following
the instructions in 8.6 - Mounting and tensioning a new planetary belt.

Completely remove the tensioner (Fig.8.6.10-1). Make 2 signs
on the dismounted belt exactly 10 cm apart (on belt not under
tension) (Fig. 8.6.2). When under tension, the marks should be
10.2 cm apart (2% extension), with a maximum of 10.25.
BELT WILL BE DAMAGED AND IT WILL NEVER RECOVER
ITS ORIGINAL TENSION
Reinstall the belt around the planetary pulley; ensuring the
belt goes around the driving pulley (Fig. 8.6.3). Put the belt
around the left roller of the tensioner (Fig. 8.6.4). Put the
tensioner back in place and pull the belt from the roller on the
right side (Fig. 8.6.5). Put the belt around the driving pulley
(Fig. 8.6.6). Begin to tension until the 10 cm between the
marks stretches to 10.2 cm(Fig. 8.6.7) (Fig. 8.6.8). Rotate the head while tensioning to allow regular
tension distribution along the belt. Tighten the tensioner by turning the bolt. Move the planetary head so
the belt has freedom to move. (Fig.8.6.8). Do not forget to retighten the screws on the tensioner (Fig.8.6.9).
8.7 REPLACING BELT AND PULLEY UNITS
In this section, we explain how to replace the belt and the pulley units. In some instances, the belt can be
replaced without replacing the pulley units, but it is always necessary to check that the pulley units are
working properly.
Disconnect the extension cord from the power line and pull out the hoses.
Pull out the socket from the motor cable to the carriage (Fig. 8.7.1).
Pull the water hose from the tank (Fig. 8.7.2) Dismount the tool holders as
previously described (Fig. 8.7.3).
Remove the two pins from the
brackets (Fig.8.7.4)
Separate the carriage from the main
head. Dismount the machine support
Dismount the guard assembly.
(Fig. 8.7.5)
Unscrew the top cover and remove it by pulling it over the motor.(Fig. 8.7.6)
Mount back the machine support as this will make it easier to turn over the main head. (Fig. 8.7.7)

8.7.1 REPLACEMENT OF THE PULLEY UNITS
Set the bottom cover assembly aside (Fig.8.7.1.1) Remove the belt by turning the pulleys by hand, while
pushing the belt off (Fig.8.7.1.2). Turn the units to ensure that the bearings are working properly. (Fig.8.7.1.3)
Units whose bearings are worn out or do not turn with ease should be replaced.
First, unscrew the nut, which is holding the pulley unit (Fig.8.7.1.4). When released, pull out the whole unit
(Fig.8.7.1.5). Carefully pull out the unit with crowbars, but do not use excessive force.
8.7.2 MOUNTING THE BELT
Bolt on the belt-replacing tool according to the picture (Fig.8.7.2.1). See the belt-replacing tool is in down
position (Fig. 8.7.2.2 idth showing over the pulleys (Fig. 8.7.2.2), and slowly
begin to turn the belt replacing tool and the pulleys. Keep turning until the belt is on the pulleys (Fig. 8.7.2.3).
