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
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-X/32-X-HV, 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 bolts 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 (16-18lbf.ft).
It is very important to regularly 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 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
CHECK AND REPLACE EVERY 50 WORKING HOURS
Change engine oil, while changing check for leakage of engine oil at the various seals. The hour meter will blink
between 48-52 hours as a reminder /"Engine Oil Capacity" is 1.5L(1.6US.qt) when oil filter is not removed;
1.7L(1.8US.qt) when oil filter is removed/.
Recommended Oil Change Intervals
Do not exceed the 50-hour oil change interval. Oil changes more frequent than 25 hours will give even longer engine
life. In any case, always use 30HD or 10W30 engine oil with all of the following ratings: SF, SG, and CC. make sure the
oil level is maintained at the "FULL" level.
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, plugs, vacuum hoses and water tank and filter. Also, check the water flow of the pump.
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 Figure 9.7.2
to check of the planetary chain. Lubricate the chain with chain lubricant and correct the sag if needed.
