7. MAINTENANCE AND INSPECTION
7.1 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 and vacuum hoses.
7.2 CHECK DAILY
After operating the Lavina® ELITE machine, the operator should conduct a visual inspection of the machine. Any defect should
be taken care of 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 [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.
Screws should be torqued to 22-25Nm (16-18 ft/lbs).
It is very important to regularly check the screws [2] that fix the "Quickchange" holder to the safety part, so that the holder
does not fly away if the buffers get damaged.
7.3 CHECK AND REPLACE 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, vacuum hoses and 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 hoses.
Carefully inspect the bearings of the grinding unit, and replace any showing signs of excessive wear. Dismount the tool
holder and replace all parts (elastic element, buffers, and sealers) with the slightest damage.
