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.
CHECK DAILY
After operating the Lavina
®
32-S-E, 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. The key lock holders
(butterflies) on the tool holders 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 has to be tightened immediately for safety
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 check regularly the screws(Fig.8.1
2),that fix the "Quickchange" holder to the safety part, so that holder
will not fly away if the buffers got damaged.
“Quickchange” should be clean. The tension of the planetary
belt can be daily checked by moving the main head and feeling the
resistance of the moving pulleys, if the belt slips tighten if necessary,
as described in the chapter Troubleshooting .
CHECK AFTER THE FIRST 15 WORKING HOURS
The low cover has a control cover (Fig. 9.4.1) 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”.
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
TROUBLE SHOOTING.
Carefully inspect the seal rings and bearings of the grinding units, and replace any showing signs of excessive
wear.
For more information, refer to chapter troubleshooting below.
CHECK EVERY 400 WORKING HOURS
Besides the checks of 200 working hours, open up the bottom cover like described in chapter “TROUBLE SHOOTING
REPLACING BELT TENSIONING. Check if sealers, belt and bearings are in good condition, change if needed. Beware
by tensioning the belt not to “over tension”; the belt will never regain his original tension.
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
ELECTRICAL SYSTEM
Dust should not enter the control box, as it will destroy the contacts. Remove (blow out) any dust present.
MECHANICAL PARTS
Parts such as the belt, seal rings, cap rings, spiders and buffers and guard assembly are subject to wear and should be
replaced as needed.
