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 32® Pro/32®HV Pro, 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.
Shock absorbers A01/00.00.01 (See page Floating backer plate) are consumables and have to be checked daily and
replaced if needed. Buffers and spiders (See page SA tool holder and page SAM tool holder) are consumables and
must be visually checked daily and replaced if needed. The key lock holders on the tool holders should be also
checked.
CHECK AFTER THE FIRST 15 WORKING HOURS
Check the belt tension after 15 hours operation.
The low cover has a control cover (Fig. 8.1) 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”. Every time you open the control cover, you have to seal it back
with sealant. Mount all the screws with washers.
CHECK EVERY 100 WORKING HOURS
Check every the backlash of the chain and sprocket. Check also for excessive wear, by checking the teeth (if sharp
replace).For the backlash see chapter TROUBLESHOOTING replacing the gear unit (page 17), and use the delivered
gauge.
You can replace only the chain wheel sprocket (Item No L32B-01.03.00.00.05 see
table on page 31).
The timely replacement is important in order to avoid chain break and further repair
costs.Clean and lubricate the gear regularly to keep it in good function
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. Also, check the water flow.
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. 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.
Machines with floating backer plate tool holder (Fig. 12.3.1 and Fig. 12.13.1)
Dismount the seal assemblies (See Troubleshooting) replace all parts (pins, seal assemblies, “O” rings) with the
slightest damage or consume. Check the floating backer plates; replace sealer fronts, shock absorbers.
Machines with SA tool holder (Fig. 12.3.2 and Fig. 12.13.2) or with SAM tool holder (Fig. 12.3.3 and Fig. 12.13.3)
Dismount the tool holders (See Troubleshooting) replace all parts (Spider, buffers, sealer caps, “O” rings) with the
slightest damage or consume. Check again
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.
