8. 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.
CHECKDAILY
After operating the Lavina®16-S-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 spiders 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 (butterflies) should be also checked.
Check the rubber buffers and fixing of the holders. The flange holding the buffers
(Fig.8.1 1)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. Tightening force of the screws has to be
25...30N.m(18...22 ft/lbs).
It is very important to check regularly the screws(Fig.8.1 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. The tension of the planetary belt can be daily
checked by moving the main head and feeling the resistance of the moving pulleys, if
the belt slips tension immediately, like 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 (Spider, buffers, sealer caps, “O” rings) with the
slightest damage or consume.
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
Besides the checks of 200 working hours, replace sealer and V-rings like described in chapter
“TROUBLESHOOTING REPLACING BELT AND PULLEY UNITS. Check if belts 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.
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.
ONE PHASE CONNECTION
Please note: the power cable has 3 wires, one ground is yellow/green the other 2
other colors are “hot” wires and should be connected to the phases. (Fig. 8.2)

9. TROUBLESHOOTING
INDEX OF PROBLEMS AND SOLUTIONS
9.1 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 is 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 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 needed you have replace all the cables with cables with bigger gage rated for the length and amperage.
9.2 DISMOUNTING AND MOUNTING TOOL HOLDER TO CHANGE BUFFERS AND SPIDERS, CHANGING
SEALERS
To check or replace the buffers and the spiders, the tool holders have to be dismounted.
Remove the countersunk screws on top of the buffer (Fig.9.2.1). Take the disc off
(Fig.9.2.2), the spider can be removed or replaced (Fig.9.2.3). By loosing four Hex cap
bolts (Fig.9.2.4), the disc comes loose (Fig.9.2.5; Fig.9.2.6) and the buffers can be
replaced(Fig.9.2.9). Attention, by mounting use always the “blue” thread locking adhesive,
except on the bolts to lock the buffers. Use always original bolts(Fig.9.2.7).
Depending on the number (3 or 6) of buffers, the holder can be more flexible or rigid.
When the tool holder is dismounted, you can change the sealers(Fig.9.2.8).
Take out Adaptor with sealer and change it.

9.3 TENSIONING AND REPLACE THE PLANETARY BELT
If the belt slips or is broken separate the carriage from main head, pull out motor plug (Fig. 9.3.1), water-(Fig.
9.3.2) and vacuum tubes. Remove the two pins from the brackets (Fig. 9.3.3). Dismount the top cover (Fig. 9.3.4,
Fig. 9.3.4).
9.4 TENSIONING USED PLANETARY BELT
Noticing speed lost in planetary movement it is possible to tension the belt for planetary movement as described
in 9.5 Mounting and tensioning a new planetary belt.

Dismount completely the tensioning device (Fig. 9.5.1). Make 2
signs on the dismounted belt exactly 10 cm out of each other (belt
without tension) (Fig. 9.5.2). The purpose is to measure 10.2 cm on
the belt in tension what is a tension of 2%., a maximum of 2.5% is
allowed.
ATTENTION: NEVER “OVER” TENSION THE BELT, THE BELT
WILL BE DAMAGED AND IT WILL NEVER RECOVER ITS
ORIGINAL TENSION
Mount the belt back around the planetary pulley; see that the belt is
behind the driving pulley (Fig. 9.5.3). Put the belt around the left
roller of the tensioning device (Fig. 9.5.4). Put the tensioning device
back in place and pull the belt from the roller on the right side (Fig.
9.5.5). Put the belt around the driving pulley (Fig. 9.5.6). Begin to
tension until the measure of 10 cm between the marks becomes
10.2 cm (Fig. 9.5.7) (Fig. 9.5.8). Tighten the tensioning device while turning the bolt move the planetary head so
the belt can slide. (Fig. 9.5.8). Do not forget to lock the tensioning device (Fig.9.5.9).
9.6 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, although it is always necessary to ensure 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. 9.6.1).
Pull the water hose from the tank (Fig. 9.6.2)
Pull the handle out and put the head of the machine in an upright position. Take out the tools (Fig. 9.6.3).
Dismount the tool holders as described in the earlier paragraph “mounting and dismounting (Fig. 9.6.4).
Remove the two pins from the brackets (Fig.9.6.5)
Separate the carriage from the main head. Dismount the machine support Dismount the guard assembly. (Fig.
9.6.6)
Unscrew the top cover and remove the top cover by pulling it over the motor. (Fig. 9.6.7)
Mount back the machine support as this will make it easier to turn over the main head. (Fig. 9.6.8)

9.6.1 REPLACEMENT OF THE PULLEY UNITS
Set the bottom cover assembly aside (Fig.9.6.1.1) Remove the belt by turning the pulleys by hand, while pushing
the belt off (Fig.9.6.1.2). Turn the units to ensure that the bearings are working properly. (Fig.9.6.1.3) 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.9.6.1.4). When released, pull out the whole unit
(Fig.9.6.1.5). Carefully pull out the unit with crowbars, but do not use excessive force.
9.6.2 MOUNTING THE BELT
Bolt on the belt-replacing tool according to the picture (Fig.9.6.2.1). See the belt-replacing tool is in down position
(Fig. 9.6.2.2). Lay the belt with only ½ of its width showing over the pulleys (Fig. 9.6.2.2), and slowly begin to turn
the belt replacing tool and the pulleys. Keep turning until the belt is on the pulleys (Fig. 9.6.2.3). Only putting ½ of
the belt width is very important otherwise if the belt is initially mounted complete over the pulleys, it will be “over”
tensioned and destroyed.
ATTENTION: NEVER “OVER” TENSION THE BELT, THE BELT WILL BE DAMAGED AND IT WILL NEVER
RECOVER ITS ORIGINAL TENSION
Apply the seal ring in the channel of the aluminum cover and close the machine.
Reassemble in the same manner.
