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, vacuum hoses, water
tank and the Propane installation.
7.2 CHECK HOURLY
7.3 CHECK DAILY
After operating the Lavina® ELITE 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.
7.4 CHECK AND REPLACE AFTER THE FIRST 15 WORKING HOURS
Check the belt tension after 15 hours working with the machine.
The bottom cover has a control cover (Fig.7.2) 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, mount back all the screws.
7.5 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 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.
Open the service cover on the motor base (Fig 7.2) (Fig 7.3) to check of the
planetary chain. Lubricate
the chain with special lubricant for chains and correct
the sag if needed
. For sagging correction (See TROUBLESHOOTING).
Dismount the tool holders (See Troubleshooting) replace all parts (elastic element,
buffers, and sealers) with the slightest damage or consume.
Return machine to
authorized service center for overall checkup of the Engine. For Propane safety,
have the machine serviced by a Certified Technician , including emission check.
7.6 CHECK AND REPLACE EVERY 400 WORKING HOURS
Besides the checks of 200 working hours, replace sealer and V‐rings like described in chapter “TROUBLESHOOTING
REPLACING BELT AND PULLEY UNITS. Check if belts and bearings are in good condition, change if needed.
Return machine to authorized service center for overall checkup of the Engine. For Propane safety, have the machine
serviced by a Certified Technician, including emission check.
7.7 VACUUM
As stated previously, frequently check hoses and othe r parts for clogging.
7.8 WATER LEAKS
