7. MAINTENANCE AND INSPECTION
REMARK
Tampering w/Emission Control System Prohibited
Federal law and California State law prohibits the following acts or the causing thereof: (1) the removal or rendering
inoperative by any person other than far purposes of maintenance, repair, or replacement, of any device or element at design
incorporated into any new engine for the purpose of emission control prior to its sale or delivery to the ultimate purchaser or
while it is in use, or (2) the use of the engine after such device or element of design has been removed or rendered
inoperative by any person. Among those acts presumed to constitute tampering, involve the parts/systems listed below:
Carburetor and internal parts
Spark plugs
Magneto or electronic ignition system
Fuel filter element
Air cleaner elements
Crankcase
Cylinder heads
Breather chamber and internal parts
Intake pipe and tube
Mechanical Parts:
Parts such as the belt, seal rings, cap rings, spiders, buffers, guard assembly, tires are subject to wear and should be replaced as
needed.
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
BONNET FILTER
‐ Make sure the bonnet air filter a top the engine is clean. It should be changed hourly and thoroughly
cleaned before reuse. The same for the recoil dust filter. If neglected the engine will overheat and carbon monoxide
emissions will elevate.
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 8 WORKING HOURS
Replace the oil in the engine after the first 8 hours work, according to the instructions
of the engine manufacturer.
Always use 30HD or 10W30 engine oil with all of the following ratings: SF, SG, and CC.
7.5 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.
