7. MAINTENANCE AND INSPECTION
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® 32Е/32ЕHV, 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. The key lock holders (butterflies) on the tool
holders should be also checked.
Check the rubber buffers and make sure the holders are secure. The flange
holding the buffers (Fig.7.1-1) has to be firmly secured to the unit. A gap seen here
indicates loose screws securing the holder. The screws have to be tightened
immediately to safely operate the machine. Working with loose screws could cause
serious damage to the machine. The tightening force on the screws should be 22-25N.m
(16-
18ft∙lbf).
It is very important to r
egularly check the screws that secure the “QuickChange” holder
to the safety part (Fig.7.1- 2), so that the holder will not fly away if the buffers get
damaged. The “QuickChange” should also be cleaned.
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 plugs, vacuum hoses and water tank/filter. Also, check the water flow of
the pump. Check the guard assembly. Ensure the wheels are clean and rotate properly. Inspect the control buttons. If
there are defective control parts, they should be replaced immediately. Replace any worn vacuum or water hoses.
Open the service cover on the motor base (to check the planetary chain. Lubricate the chain with chain lubricant and
correct the sag if needed. (For sagging correction see TROUBLESHOOTING 8.4)
Dismount the tool holders (See TROUBLESHOOTING) and replace any parts (elastic element, buffers, sealer caps,
“O” rings) showing any damage.
For more information, refer to chapter troubleshooting below.
CHECK EVERY 400 WORKING HOURS
In addition to checks made every 200 hours, check if sealers and bearings are in good condition and change if
needed.
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.
