SAFETY INSTRUCTIONS RECOMMENDED USE The LAVINA® 30GX machine is designed and manufactured to grind and polish concrete, terrazzo and natural stone floors. It can be used for renovations as well as for polishing. The machine is designed for dry or wet use. When using it dry, use a vacuum of appropriate size. For more information, please refer to the chapter on handling the vacuum connection. PROHIBITED USE The machine MUST NOT be used: For applications different from the ones stated in the General Description chapter. In environments which: - Possess risks of explosion -Possess high concentration of powders or oil substances in the air Superabrasive User Manual Original Language Lavina® 25G‐X 2/2015 The two greatest hazards with propane powered floor care machines are: - Carbon Monoxide Poisoning: This is the most frequently reported incident associated with propane powered floor care machines and is caused by excessive exhaust emissions. The symptoms are headache, dizziness and nausea. A major cause involves engines with poor preventive maintenance practices, usually those with dirty air filters and machines operated in confined areas without adequate ventilation. Another cause may be substandard, inexpensive machines with no emissions control technology and improperly set carburetion. - Overfilled Fuel Cylinders: Nearly all fire relatedincidents reported result from bringing a cylinder into a building without first checking for overfill. This action is PREPARATION FOR WORK dangerous, unwise, and unnecessary.

The relative darkness of the indicator button indicates the level of CO in the ambient atmosphere. Most indicator badges have a useful life of 30 days, depending on the concentration of contaminants, humidity, and temperature. TESTING There are a great number of instruments offered on the market to test for toxic gases. Only those designed to read carbon monoxide resulting from combustion engines is considered acceptable for testing exhaust emissions from propane powered floor machines. Some instruments are used to read “ambient air” and may be damaged if used to take readings in the muffler or tail pipe. Selecting the proper instrument is an important part of meeting the testing requirements. Generally speaking, units capable of reading in ppm, (parts per million), at ranges from 0 to 1000 are adequate for checking ambient air (air in the breathing zone of the operator). Instruments capable of testing carbon monoxide in the exhaust should be able to read from 0 to at least 2000 ppm and should be certified by the manufacturer for that purpose. Some instruments and systems used for these purposes are: 1) AMBIENT AIR MONITORING DRAGER Model 190: Manufactured by National Drager.

Only one operator at a time can work with the machine. The operator must be properly trained and well instructed prior operating the machine. The operator must understand all the instructions in this manual. Lavina® 25G‐X 2/2015 The operator must understand and interpret all the drawings and designs in manual. The operator must know all sanitation and safety regulations pertaining to the operation of The operator must have floor grinding experience. The operator must know what to do in case of emergency. The operator must have an adequate technical knowledge and preparation. The operator is expected to operate their equipment safely and responsibly. They are responsible for the proper handling and storage of propane cylinders, identifying potential hazards associated with his job and avoiding these hazards at all times. PROPANE CYLINDERS The Propane cylinders are constructed of either aluminum or steel. We recommend aluminum because it is lighter and guards against rusting. The cylinder used on propane powered floor machines is classified as a 4E240 cylinder. Its rated capacity is 20 lbs. and this designation refers to the model of the cylinder. Actual propane capacity achieved during filling can be less than, equal to, or slightly more than 20 lbs. Use only UL, CTC/DOT listed cylinders. The propane cylinder used on the floor machine is a motor fuel cylinder as listed by the Department of Transportation. Unlike the common 20‐lb propane outdoor grill cylinders (which are not legal for use on propane floor machines), the motor fuel cylinder has a number of safety systems designed into it to ensure your safety at all times. There are two types of 20 lb. motor fuel cylinders. Liquid draw Vapor draw The liquid draw cylinder is used on larger vehicles like forklifts. These machines have special vaporizing carburetors to allow the propane to change from a liquid to a gas before being burned in the combustion chamber. The vapor draw cylinder is used on small machines like the propane powered floor care machines. The vacuum generated by the engine draws up the Propane gas vapor through the fuel system. The propane powered floor care machine does not have an evaporating system and will freeze up if liquid propane is introduced to it. It is necessary that special attention be paid to ensure that neither the liquid nor the vapor draw cylinders be overfilled. REFUELLING CYLINDERS The proper filling of propane cylinders is a subject so important that it warrants special attention. Propane cylinders should only be filled by qualified propane dealers. Most important, propane cylinders should be filled no more than 80% of their rated capacity. The other 20%, which is about 4” (10 cm) from the top of the cylinder, is called the vapor space or headspace. This vapor can be compressed without causing the pressure relief valve to open and vent gas to the area around the cylinder. If there is no headspace to allow for fuel expansion, the pressure relief valve will open, releasing propane gas into the atmosphere. This is a very dangerous and volatile situation as there is always the possibility that enough of the vented gas could find its way down to the floor and come in 9 Superabrasive User Manual Original Language Lavina® 25G‐X 2/2015 contact with a pilot light from a furnace, hot water heater, or other source of ignition.

Figure 3.6 STORAGE Always store and transport the LAVINA® X machine in a dry place. Never transport the LAVINA® X machine unprotected; it may be damaged if transported unprotected during rain or snow. When during the storage of the machine the temperature may fall down to or less 32F (or 0o C) you should empty the water from the system using following steps: ‐ Pull out the hose of the tank (Fig.3.7) ‐ Using compressed air blow out the water from the system for the two positions of the turn‐cock (Fig. 3.8, Fig. 3.9). Figure 3.7 Figure 3.9 Figure 3.8 11 Superabrasive User Manual Original Language Lavina® 25G‐X 2/2015 4. OPERATION PRELIMINARY CONTROLS Inspect the working area as explained in the safety instructions. For wet use, fill in the water tank or connect the vacuum extractor and ensure that the vacuum hose is clear and it will follow the machine easily. Make sure the bonnet air filter on top of the engine is clean. It should be cleaned hourly. Check the engine oil level, screw the dipstick in to get reading. See to it the tank is fill up (see also “Storage Propane tanks). TANK and FUEL LINES ‐ The tanks has already been covered but do the fuel lines show any sign of wear and tear, such as cracks or any corrosion. Screw the brass fuel line fitting onto the tank service‐valve hand tight only. This connection MUST be secure because the service valve has a safety valve inside it, which will only open if the brass fuel‐line fitting is COMPLETELY seated into the service valve. WATER FLOW CONTROL UNIT The operator can choose the water sprayer in the front when the tap is in the horizontal position (Fig.4.1), the water will spray under the cover of the machine when the level is in the vertical position (Fig.4.2).The flow regulating valve located on the tank (Fig.4.2.1) is increasing or reducing the water flow to the working area – in front of the machine or under the main head cover of the machine. Figure 4.1 Figure 4.2 Figure 4.2.1 ADJUSTING AND MOUNTING TOOLS The Holder A41 in LAVINA® X can work with either 3 or 6 buffers which will change its elasticity. You can make the change after dismounting the holder as per the instruction in TROUBLESHOOTING. In Lavina 25G‐X the holder is initially mounted with 6 buffers. Mount the tools only after ensuring that there is enough Figure 4.4 Figure 4.3 diamond bond material left. Be sure that the plates are always clean before mounting. WARNING: Always Secure the“Quickchange” pads with the security plate (Fig.4.3), lock with the tool holder key (Fig.5.3). Diamond tools with Velcro are attached on three foam plates of 9 inch (Fig.4.4). The foam plates are ounted on the key lock (butterfly).Always use the tool holder key (Fig.5.3). ALARM EnviroGard employs a sensor (Fig. 4.6) in the exhaust path between the engine and the catalytic muffler to detect the oxygen content of the exhaust before it is passed through the catalyst. The oxygen sensor does not react to nor does it measure the CO content of the exhaust. It responds only to oxygen content. The Control Module is set to ignore the readings from the oxygen sensor during the first three minutes the engine is running. This period allows: The sensor to reach a stable operating temperature. Figure 4.6 The catalyst in the muffler to reach the temperature necessary to reduce the levels of CO, nitrogen oxides (NOx) and hydrocarbons (HC) in the exhaust. The most common event in which the Control Module shuts down an engine is when the air filter becomes dirty enough to restrict the air intake flow, which changes the air‐fuel ratio such that the oxygen sensor signal is outside the control limits. Once the air filter is properly cleaned, operation of the machine can be resumed. 12 Superabrasive User Manual Original Language Lavina® 25G‐X 2/2015 CONTROL BOARD pm engine 2000 2100 2200 2300 2400 2500 2600 2700 2800 2900 3000 3100 3200 3300 3400 3500 3600 rpm tools 570 600 630 660 690 715 745 775 800 830 860 890 915 945 975 1005 1030 THE CONTROL BOARD 1 Start/Stop Engine switch Turn key to the right for contact full right for starting the engine, to stop key to left full left is contact 2 Start/Stop clutch Start will electronically activate the grinding plates to spin, by pushing stop it will disconnect engine from grinding heads 3 Throttle Push forward to accelerate. 4 Digital RPM/workings hours indicator When the motor runs it indicates the revolutions per minute of the motor, see the conversion table to know the rpm of the tools.

STARTING THE MACHINE First, follow the directions in chapter Safety Devices and Safety Instructions. Check oil level. Open (counterclockwise) the service valve on the propane tank about one and a half turns. Next, see to it the Start/Stop clutch button (2) is in stop position check the throttle (3) in the IDLE position. This creates a vacuum necessary to open the lock‐off valve inside the regulator. Actuation of the throttle lever will keep the lock‐off valve from opening and the engine from getting fuel so the engine will not start. Proper maintenance will insure easy starting. Engage starter (1) for a MAXIMUM of 5 to 6 seconds or until the engine fires. Serious starter damage will result if this is exceeded and the warranty may not apply. Operate the engine at half throttle for approximately two minutes for proper warm‐up. Then advance to full throttle for best results. If working wet, add water to the floor surface. If working dry, omit this step, and instead, switch on the vacuum unit. Finally, hold the machine firmly and push the start of the Start/Stop clutch button (2). OPERATING THE MACHINE Guide the machine in straight lines across the floor, and with each new line overlap a little bit of the previously completed surface. Work at a constant speed allowing the tools time to work at a speed appropriate for the tools’ grit size. Avoid vibrations. Do not stop the LAVINA® X machine in one spot while the tools are still working because they will leave marks on the floor surface. When working wet, open the water tank periodically to release water onto the floor surface. When working dry, check the floor surface periodically to ensure that dust is not accumulating on the surface, also check regularly if your vacuum works properly. STOPPING THE MACHINE The stopping of the machine must be done gradually until the motor stops. Do not stop moving the machine before arresting the clutch as the tools could damage the surface. To stop push Stop clutch button (2), then close (clockwise) the service valve on the propane tank. ALWAYS allow the engine to run until it stops from lack of fuel. • ONLY IN AN EMERGENCY should the "stop" position on Start/Stop Engine switch (1) Disconnect the fuel line from the tank. REMEMBER, when you are finished with the machine, store the propane tank outside the building, in a SECURE place away from heat or direct sunlight. Use the Emergency button (9) only in emergency or use it to switch the power totally off. Remember not to hold the machine in one spot before turning off until the grinding plates stop moving. 13 Superabrasive User Manual Original Language Lavina® 25G‐X 2/2015 5.

Among those acts presumed to constitute tampering, involve the parts/systems listed below: Crankcase Carburetor and internal parts Cylinder heads Spark plugs Breather chamber and internal parts Magneto or electronic ignition system Intake pipe and tube Fuel filter element Air cleaner elements 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. 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. 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. CHECK DAILY After operating the Lavina® X 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. Figure 7.1 “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/. 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. 16 Superabrasive User Manual Original Language Lavina® 25G‐X 2/2015 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 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 (Fig 7.2) (Fig 7.3) to check of the planetary chain. Lubricate the chain with special lubricant for chains and correct the sag if needed. For sagging correction (See TROUBLESHOOTING ). Dismount the tool holders (See Troubleshooting) replace all parts (elastic element, buffers, sealers) with the slightest damage or consume. Return machine to authorized service center for overall checkup of the Engine. For Figure 7.2 Propane safety, have the machine serviced by a Certified Technician, including emission check. CHECK AND REPLACE EVERY 400 WORKING HOURS Besides the checks of 200 working hours, replace sealer and V‐rings like described in chapter “TROUBLESHOOTING REPLACING BELT AND PULLEY UNITS. Check if belts and bearings are in good condition, change if needed. 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. Figure 7.3 VACUUM As stated previously, frequently check hoses and othe r parts for clogging. WATER LEAKS Replace any leaking parts immediately as the water could damage your machine MECHANICAL PARTS Parts such as the belts, seal rings, cap rings, spiders and buffers and guard assembly are subject to wear and should be replaced as needed. ELECTRICAL SYSTEM Dust should not enter the control box, as it will destroy the contacts. Remove (blow out) any dust present. Electrical schemes with Kawasaki Engine 17 Superabrasive User Manual Original Language Lavina® 25G‐X 2/2015 8. TROUBLESHOOTING 8.1 ENGINE When troubles occur, be sure to check the simple causes which at first, may seem too obvious to be considered. For example, a starting problem could be caused by fuel starvation due to an empty propane cylinder or an unopened service valve. If you do not check for this, starter burnout could result. Some Troubles and solutions: Surging idle To smooth out the engines' idle characteristics, adjustment is provided by an idle screw on the lower left side of the carburetor as viewed from the operator's position. The screw is bright steel and 1/4" in diameter with a Phillips head on it. Rotating the screw clockwise will increase the idle speed and this should cure the "surging idle". If it does not, call our customer service. Engine starts and idles, but will quit as the throttle is advanced It is possible that the propane tank's service valve is faulty. To check for this, close the valve completely and then reopen very slowly while you listen for a "click" when the gas begins to travel through the valve. If you hear this very slight noise, the valve is only partially opening. This allows enough gas through to start and idle the engine, but not enough for full throttle operation. As the throttle is increased, allowing more air to enter the intake, the engine will quit from fuel starvation. Call your dealer or the factory for instructions on where to have the service valve replaced. Meanwhile, to get by, you can continue to open the service valve until you do not hear a “click" and then the engine will run normally. If it does not, call your customer service. Starter barely turns the engine over or the solenoid just clicks The battery is likely low in charge. This can be remedied by recharging the battery using a 12 Volt battery charger at 4.12 amperes. The battery is located on the left side of the propane tank holder under the battery cover. The positive post is the one with the RED cable attached to it. Follow the instructions that came with the battery charger. REMINDER: this will continue to happen unless your engine is run for sufficient time between starts to recharge the battery 8.2 CHECKING AND CHANGING OIL Figure 8.2.1 Figure 8.2.2 Check the engine oil level, screw the dipstick in to get reading. While changing engine oil, check for leakage of engine oil at the various seals. The hour meter will blink between 48‐52 hours as a reminder. 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. 8.3 SEPARATING THE HEAD FROM THE CARRIAGE Please note that the propane cylinder has to be removed and stored outside before any maintenance or reparation is done. Figure 8.3.1 Figure 8.3.2 Figure 8.3.3 18 Superabrasive User Manual Original Language Lavina® 25G‐X 2/2015 Pull the connector of the battery (Fig. 8.3.1), pull out the Propane hose (Fig. 8.3.2), the connectors of the lamp (Fig. 8.3.3), dismount the control panel (Fig. 8.3.4), and take off all water and vacuum hoses (Fig. 8.3.5). Remove the tank (Fig. 8.3.6). Now it is possible to separate the head by removing the pins; two people are needed to do this operation: one person holds the carriage the other pulls the pins (Fig. 8.3.7). Figure 8.3.4 Figure 8.3.5 Figure 8.3.7 Figure 8.3.6 8.4 DISMOUNTING/MOUNTING THE ENGINE Figure 8.4.1 Figure 8.4.2 Figure 8.4.3 Separate head from carriage (see previous chapter).

You will need deep metric socket 13mm with outside diameter not more than 3/4in to unscrew the four bolts (Fig.8.6.1) and remove the holder (Fig.8.6.2) When the tool holder is dismounted, you can change the sealers (V‐Ring and Felt‐Ring). By loosening four Hex cap flange bolts (Fig.8.6.3) the adaptor comes loose. Unscrew the six screws of the cap (Fig.8.6.4) holding the felt‐ring. Take out the Felt‐Ring, adaptor and V‐Ring. Mount the V‐Ring with the smallest lip of the V to inside (Fig.8.6.5) just push the V‐Ring so the top is on the same level as the pulley top (Fig.8.6.6). Then take the adaptor and push the V‐Ring down with the adaptor (Fig.8.6.7). The lowest lip of the V‐Ring should only barely touch its gliding surface; also never push the V‐Ring down with fingers. Mount the adaptor and the Felt‐Ring on top (Fig.8.6.7). Close the sealers with the cap (Fig.8.6.8) and screw the bolts. Always use the original bolts. 20 Superabrasive User Manual Original Language Lavina® 25G‐X 2/2015 8.7 DISASSEMBLING AND MOUNTING TOOL HOLDER TO CHANGE BUFFERS AND ELASTIC ELEMENT When the TOOL HOLDER is disassembled you can change defective parts – elastic element, buffers, etc. Lift the locking pin (Fig.8.7.1) to dismount the retaining washer (Fig.8.7.2). Take out the screws on the buffers and the nuts of the elastic element (Fig.8.7.3;Fig.8.7.4). Remove the elastic element from the QC plate (Fig.8.7.5). While the holder is dismounted (Fig.8.7.6;Fig.8.7.7) clean the parts and replace the defective with new ones. Assemble the holder with Figure 8.7.2 Figure 8.7.3 Figure 8.7.1 new buffers with new screws and new elastic element. Put the retaining washer (Fig.8.7.8) and push the locking pin (Fig.8.7.9). This will prevent the fall of the washer when mounting the holder on the machine. Figure 8.7.6 Figure 8.7.4 Figure 8.7.5 Make sure the four bolts holding the adaptor (Fig.8.7.12) are reliably Figure 8.7.7 tighten. Mount the holder on the machine using the same socket as mentioned in 8.6 (Fig.8.7.10;Fig.8.7.11). The retaining washer fits into the central hole C of adaptor and the four bolts into the thread holes Т (Fig.8.7.12). The holder is centered on the outside diameter of the adaptor. Ensure the connection of the holder on the forehead of the adaptor and then tight evenly the four bolts. Tightening force of the bolts has to be 22...25N.m(16...18 ft/lbs). Mounting the holder without retaining washer (Fig.8.7.2) is INADMISSIBLE because the security system preventing the separation of part of the holder in case of broken buffers and elastic element will not function! You can change the butterfly of the holder without dismounting the holder of the machine. Fig.8.7.13 is 3‐d section view of the holder, showing its parts. The numbering is the same as in Spare parts.

To change the main belt you have to remove all holders and dismount their adaptors. Dismount the sealing. Carefully check the friction surface (flanges of the lower cover and the outside diameter of the adaptors). Decide if they are in good condition (wear out, smoothness of surface) and whether they can work until next inspection. Remove the bottom cover, unscrew the bolts on the outskirt and the three bolts of the spacers ( Fig. 8.11.1). Under the cover on the outskirt there is a sealer, and the spacers have O‐Rings. The change of all seals together with the belts is Figure 9.7.4 recommended. Fig.8.11.5 shows the scheme of belts location. To dismount the old belts first dismount the planetary belt pos.1 and after that the main belt pos.6. To dismount the main belt pos.6 unscrew nuts on pos.4 and pos.5 enough to be able to turn the tensioners pos.3 around the central axle. Clean the washers and space around, and check if all bearings of pulley units or tensioners are in good condition (check for too much Figure 8.11.5 clearance or rolling noise). Rotating the tensioner will allow the centre distance to be reduced in such a way that the timing belt may be fitted without force. Installation with the use of force is NOT permissible at any time as this can damage the high quality, low stretch tension cord and other components. This damage is often not visible. Put the belts in pos.6 as per the scheme, and pay attention for their correct position in every pulley. Screw up until it stops and loosen on the half moons the nuts on pos.4, allowing the rotation of the tensioners at minimum inclination. Using nuts on pos.5 tighten the belt, verifying again the correct position of the belt, and the correct gearing in every pulley. Rotate the gear while tensioning to allow regular tension distribution on the belt. Control the tension using Frequency tension Tester (Optibelt 3 TT) (Fig. 8.7.3). Tension in span “А” of the belt should be 120‐130Hz. It is possible for tensioning while changing the belt to use pre‐ installed support (Fig.8.11.5‐2) (Fig.8.11.6) (only when its factory position is not changed), to limit the turn of the tensioner when the required belt tension is done. ATTENTION:NEVER “OVER” TENSION THE BELT, THE BELT WILL BE DESTROYED AND IT WILL NEVER RECOVER ITS ORIGINAL TENSION Figure 8.11.6 To dismount the planetary belt (Fig.8.11.5‐1) unscrew the screw of the front washer (Fig.8.11.7) and the two screws of the conical sleeve (Fig.8.11.8). Screw one screw in the free thread(Fig.8.11.9), to push the washer down (Fig.8.11.10); take the conical sleeve and the belt (Fig.8.11.11). You can help with a flat screw driver if the sleeve is not going out easy. (Fig.8.11.12). 24 Superabrasive User Manual Original Language Lavina® 25G‐X Figure 8.11.7 Figure 8.11.8 Figure 8.11.9 Figure 8.11.10 Figure 8.11.11 Figure 8.11.12 2/2015 The essembly is on reverse order, and is important to match the threads of the conical sleeve and the belt washer(Fig.8.11.13). Put the front washer (Fig.8.11.14), on the screw use always the “blue” thread locking adhesive. Tightening force of the bolts has to be 4,5...6N.m(3,3...4,4 ft/lbs). Put carefully the two binder screws by leaving the central thread free.(Fig.8.11.14)(Fig.8.11.15). Insert the screws up to revolution and ½ by alternating until the conical sleeve pull up the belt pulley. The conical sleeve must be aligned in height with the belt washer(Fig.8.11.16). Figure 8.11.14 Figure 8.11.13 Dismounting the planetary belt is possible without removing of the Bottom cover assembly. Unscrew the eight bolts, take the service window cover and the sealing(Fig.8.11.17)(Fig.8.11.18). Dismount the planetary belt (see 8.11.)

Dismount the tool holders, sealers and bottom cover see Fig.8.11(TENSIONING AND REPLACING THE BELTS). Unscrew the cap that gives access to the fastening bolts of the driven chain wheel (Fig.8.12.1)(Fig.8.12.2). Roll the main head to the position when from the hole of the cap you see a fastening bolt of the driven chain wheel (Fig.8.12.3). You will need magnetic deep metric socket 10mm with outside diameter not more than 11/16 in to unscrew the six bolts (Fig.8.12.3)(Fig.8.12.4) (Fig.8.12.5). Driven Chain Wheel is composed by two symmetrical halfs(Fig.8.12.6). Mount on the reverse order.
