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
MECHANICAL PARTS
Parts such as the belts, V-Ring, elastic elements, guard assembly, tires are subject to wear and should be replaced as needed.
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 Propane installation and the water tank.
CHECK HOURLY
BONNET FILTER - Make sure the bonnet air filter atop 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.
CHECK DAILY
After operating the Lavina® B36G-S machine, the operator should conduct a visual inspection of the machine during cleaning
the whole machine. Pay attention to loose bolt or screws. Any defect should be solved immediately.
Check vaccum cleaner bag daily.
Check oil level daily.
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 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 polishing units, and replace any showing signs of excessive wear. For more
information, refer to chapter troubleshooting below.

spoiler and check the main belt tension. Unscrew and pull out the
moving the main head the belt should not slip on the planetary pulley and drive the pulleys. 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.
CHECK AND REPLACE EVERY 400 WORKING HOURS
In addition to checks made every 200 working hours, replace sealer and V-rings as described in chapter "TROUBLESHOOTING -
REPLACING BELT AND PULLEY UNITS. Check that the main belt, the fan belt tension, the planetary driving belt and bearings
are in good condition, and change them if needed. Check if the elastic elements are in good condition, and change if needed.
