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.

clean.
CHECK AND REPLACE AFTER THE FIRST 15 WORKING HOURS
Check the belt tension after 15 hours of working with the machine.
The bottom cover has a control cover (Fig.7.2) that allows fast and easy control and correction of
the belt. It is recommended to check the tension of the belt after the first 15 hours and to
tighten if necessary. For the correct tension, see TROUBLESHOOTING "mounting the belt". Every
time you open the control cover, be sure to replace ALL screws.
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, and filter. Also, check the water flow of the pump. 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 tighten if
necessary. For the correct tension, see TROUBLESHOOTING.
Dismount the tool holders (See Troubleshooting), replace all parts (elastic element, buffers, sealers) with the slightest damage or
consume.
Open the inspection cover on the motor base to check the planetary driving belt, by moving the main head the belt should not slip on
the planetary (central) pulley .
CHECK EVERY 400 WORKING HOURS
In addition to checks made every 200 working hours, replace sealer and V‐rings as described in chapter "TROUBLESHOOTING
REPLACING BELT AND PULLEY UNITS". Check if belts and bearings are in good condition, change if needed.
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/ felt ring and V‐rings/, elastic element and buffers and guard assembly are subject to wear and
should be replaced as needed.

CHECK DAILY
After operating the Lavina® X 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 that flanges or discs are mounted and 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 there means that there are 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 bad damages on the machine. Tightening force of the screws has to be 22...25N.m(16...18 lbf.ft).
It is very important to regularly check the screws (Fig.7.1‐2) that fix the "Quickchange" holder to the
safety part, so that the holder will not fly away if the buffers get damaged. "Quickchange" should be
