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.
Figure 8.1
"Quickchange" should be clean. The tension of the planetary belt can be checked daily by moving the main head and feeling the
resistance of the moving pulleys, if the belt slips tension immediately, see the chapter Troubleshooting .
CHECK AND REPLACE AFTER THE FIRST 15 WORKING HOURS
Check the belt tension after 15 hours working with the machine.
The bottom cover has a control cover (Fig.8.2) 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, mount back all the 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 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 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.
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.
The Lavina® 20N‐S 200‐240 Volt will automatically detect if the connection is based on single (L1, L2) or three phase (L1, L2, L3)
208‐240 Volt. The operator does not have to switch the machine; only connect to two phases or three phases. For convenience,

CHECK DAILY
After operating the Lavina® S 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 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.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 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 25...30N.m(18...22 ft/lbs).
It is very important to regularly check the screws (Fig.8.1 2) that fix the
"Quickchange" holder to the safety part, so that the holder will not fly away if the buffers
get damaged.
