6. MAINTENANCE AND INSPECTION
FIRST USE
Before first use please mount the Levelling Wheel Assembly in place. Put the transverse
shaft (Fig. 6.1 4) in position on top of the back housing assembly (Fig. 5.1 17). Turn the
shaft (Fig. 6.1 3) from under the back housing assembly (Fig. 5.1 17) through the transverse
shaft (Fig. 6.1 4) mount the turning wheel (Fig. 6.1 6) and secure with screw (Fig. 6.1 5).
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.
CHECK DAILY
After operating the Lavina 7 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.
CHECK AND REPLACE AFTER THE FIRST 15 WORKING HOURS
Check the belt tension after 15 hours working with the machine.
For the correct tension, see TROUBLESHOOTING.
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. 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.
CHECK EVERY 500 WORKING HOURS
Besides the checks of 200 working hours, open up the bottom cover like described in chapter “TROUBLE SHOOTING
REPLACING BELT 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.
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.
ELECTRICAL SYSTEM
Dust should not enter the control box as it will destroy the contacts. Remove (blow out) any dust present.
ONE PHASE CONNECTION
Please note: the power cable has 3 wires, one ground is yellow/green the other 2 other colors are “hot” wires and
should be connected to the phases. (Fig. 6.2)
