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, water
tank and the Propane installation.
CHECK DAILY
After operating the Lavina
®
38GR-X, the operator should conduct a visual
inspection of the machine. Any defect should be solved immediately. Pay attention to
plugs and vacuum hoses loose bolt or screws.
Tool holders: Buffers and spiders are consumables and must be visually checked daily
and replaced if needed. The key lock holders (butterflies) on the tool holders should also
be 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 to the
machine. Tightening force of the screws has to be 25...30N.m(18...22 ft/lbs).
It is very important to regularly check the screws (Fig.8.1 2) that fix the "Quickchange" holder to the safety part,
so that holder will not fly away if the buffers get damaged.
“Quickchange” should be clean.
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. Clean, lube, and tension the chain at this point as well.
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 special lubricant for chains and correct the sag if needed.
