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 can
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
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.8.2) that allows for fast and easy control
and correction of the belt. It is recommended that the tension of the belt be tested
after the first 15 hours, and tightened if necessary. For the correct tension, see the
chapter: TROUBLESHOOTING "mounting the belt". Every time you open the control
cover, mount all the screws back with washers.
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 cords and plugs,
vacuum hoses and the water tank filter. Also, check the water flow of the pump. Check the guard assembly. Make certain that the
wheels are clean and are rotating 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 it when necessary. For the correct
tension see the chapter, TROUBLESHOOTING.
Dismount the tool holders (see TROUBLESHOOTING) replace all parts (spider, buffers, sealer caps, "O" rings) with the slightest
damage.
Open the inspection cover on the motor base to check on 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 the sealer and V‐rings like described in the chapter: TROUBLESHOOTING,
replacing belt and pulley units. Check is the belts and bearings are in good condition, change if needed.
VACUUM
As previously stated, 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, 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.

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 bolts or screws.
Tool holders: Buffers and spiders are consumables and must be visually checked every day and
replaced when needed. Make sure flanges and discs are mounted and locked well in place. The
key lock holders (butterflies) should be checked also.
Check the rubber buffers and the fixing of the holdings. The flange holding the buffers (Fig8.1 1)
has to be firmly fixed to the unit. A gap seen there means that there are loose screws securing
the holder. The screws have to be tightened immediately to safely operate the machine.
Working with loose screws on the holder could also cause damage to the machine. The
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. The tension of
the planetary belt can be checked daily by moving the head and feeling the resistance of the
moving pulleys, if the belt slips tension immediately, see the chapter: Troubleshooting.
