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.
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 ft/lbs).
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 clean also.
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, power cord 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.
Separate the carriage from the main head. Unscrew the four bolts(Fig.7.2)
and take the upper cover (Fig.7.3). Check the planetary driving belt, by
moving the main head, the belt should not slip on the planetary /central/
pulley.
Dismount the tool holders (See TROUBLESHOOTING) and replace all
parts (elastic element, buffers, sealer caps, “O” rings) that have the
slightest damage.
CHECK AND REPLACE EVERY 400 WORKING HOURS
Besides the checks of 200 working hours, replace sealer and V-rings like
described in chapter
“TROUBLESHOOTING DISMOUNTING TOOL
HOLDERS TO CHANGING V-RINGS AND FELT-RINGS.
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, buffers and guard assembly are subject to wear and must 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.
