1.GENERAL INFORMATION

This owner’s manual is intended for the operator of the Lavina® X machine, the servicing technician as well as for anyone

involved with operating or servicing the machine. We recommend that you read the instructions very carefully and follow them

strictly. The manual includes information about assembling, using, handling, adjusting and maintaining your Lavina® X floor

grinding and polishing machine.

MANUFACTURER

Superabrasive was founded in 1987, as a manufacturer of high quality diamond tools for the stone and concrete industry. Today,

Superabrasive is one of the world’s leading companies in the production of diamond tools and floor grinding machinery. At

Superabrasive, we strive to deliver the very best solutions to our customers, and enable them to work more efficiently.

GENERAL DESCRIPTION

The Lavina® X machine is intended for grinding, polishing and buffing concrete, marble, granite,

limestone, and terrazzo surfaces with diamond tools.

The Lavina® X machine is a three-disc machine, which can be used dry as well as wet.

For best results, use only tools manufactured or recommended by Superabrasive and its

distributors. Additionally, the machine could be used for grinding wood floor surfaces.

The Lavina® X machine is manufactured and fitted for the above-

mentioned applications only! Every other use may possess risks to the persons involved.

MAIN DESIGN

The two main component sections of each machine are: carriage and main head.

The handle (Fig.1.2) on the frame is adjustable in height and allows the operator to work in

a correct and safe working posture.

The halogen spotlight (Fig.1.2) enables the operator to work in darker

areas.

Existing lighting system does not replace adequate overhead lighting.

The controls are positioned on top of the electrical box (fig.1.3)

The electrical box (fig.1.3) contains the electric switching devices and the inverter.

The main feeding cable is connected with a plug and socket on top. The motor feeding cable is

plugged into the socket located on the bottom of the box.

The tank is on the opposite side of the frame, so that the weight of the

water has no influence on the operation of the machine. The frame weight, on the other hand, is

fully absorbed by the driving wheels. An electric pump sprays the water through a front sprayer

or internal.

The motor is mounted on the base plate and is driving the three heads with a belt system.

The planetary head is driven by a simplex roller chain .

ENVIRONMENTAL CONDITIONS

The temperature range for operating the Lavina® X machine outdoors is between 41°F and 86°F or 5°C and 30°C. Never use the

Lavina® X machine during rain or snow when working outdoors. When working indoors, always operate the machine in well-

ventilated areas.

ELECTRICAL CONNECTION

to ensure that the machine is in working condition. Check the potentiometer (Fig.4.6-16) and ensure that it is set at the

working speed. Check the potentiometer (Fig.4.6-8) for the required working speed.

Finally, hold the machine firmly and turn the start button (Fig.4.6-6) and set movement direction of the machine – forward

or backward from the corresponding buttons (Fig.4.6-10 and Fig.4.6-11).

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.

At the end of each line you can reverse the direction of the machine by simply pressing the corresponding button

FORWARD or BACK and through the handles to direct a new runway. If you get tight the handles and trigger the button

STOP you will get to manual operated mode of the machine and can performe more complicated maneuvers. Once you

direct the machine in the desired direction activate again the selfpropelled movement. Increase or decrease of the speed

of the machine when operating can be made by the potentiometer (Fig.4.6-8)

Figure 4.6

Superabrasive User Manual Original Language Lavina® 25LM-X / Lavina® 25LM-X-HV 1/2016

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® 25LM-X-HV machine in one spot while the tools are still working because they will

leave marks on the floor surface. When working wet, preliminary chose with the water tap (Fig.4.2) the position for water

feed and periodically start the pump (Fig 4.6-7) 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.

If you need to process on the floor with a slope that requires significant effort to work with machine with manual

control, put the button SLOPE in position ON. In this position the activating the button STOP or Emergency stop will not

disconnect wheels and motorgear connection and it will serve as a break on any movement of the machine on the slope.

In that case the machine is operated by the buttons FORWARD ; BACK and STOP, but without possibility to go to

manual control and at the end of the coarse. To switch to manual operation and control of the machine get the button

SLOPE in position OFF and push the button STOP.

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 motor as the tools could damage the surface. To stop switch the off switch (Fig.4.6-15). Use the Emergency

button (Fig.4.6-14) only in emergency or use it to switch the power totally off.

Remember not to hold the machine in one spot before turning off the motor.

The machine drive is stopped by the button STOP (Fig.4.6-9) or Emergency button (Fig.4.6-14)

ALARM

The Alarm light ((Fig.4.6-15) will light incase inverter goes in alarm mode. The most common failure is motor in

overload. To reset the mode push reset button ((Fig.4.6-15).

7. MAINTENANCE AND INSPECTION

CLEANING

Keep your machine clean. Cleaning the machine in a regular basis will help detect and solve potential problems before they can

cause damage to the machine. Most importantly, check and clean the tool plate connections, power cords, plugs, vacuum hoses,

and water tank.

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, vacuum

hoses, loose bolts or screws.

Tool holders: Buffers and elastic element are consumables and must be visually checked on a daily

basis and replaced if necessary. Make sure the flanges or discs are securely locked in place. The key

lock holders (butterflies) should also be 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. If there is a gap seen here, that means the screws

securing the holder are loose. 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 of the screws has to be 22-25N.m (16-18ft/lbs).

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 be clean also.

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, power cord

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.

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 8.4 ).

Dismount the tool holders (See TROUBLESHOOTING) and replace all parts

(elastic element, buffers, sealer caps, “O” rings) that have the slightest damage.

CHECK EVERY 400 WORKING HOURS

Besides the checks of 200 working hours, replace sealer and V-rings like described in chapter “TROUBLESHOOTING DISMOUNTING

TOOL HOLDERS TO CHANGING V-RINGS AND FELT-RINGS.

VACUUM

As stated previously, frequently check hoses and other parts for clogging.

WATER LEAKS

Leaking parts should be replaced immediately because the water could damage your machine.

MECHANICAL PARTS

Parts such as the belts, seal rings, cap rings, spiders, buffers and guard assembly are subject to wear and must be replaced as needed.

ELECTRICAL SYSTEM

Dust should not enter the control box, as it will destroy the controls. Remove (blow out) any dust present

8. TROUBLESHOOTING

INDEX OF PROBLEMS AND SOLUTIONS

8.1 REPLACING POWER CORD AND PLUGS

When replacing the power cord or plugs always use cords and plugs with the same specifications as the original ones.

Never use lower quality or different types of cords and plugs.

In addition, take into consideration the distance between the appliance and the electrical source. The greater the distance, the greater

the resistance and the less current that will be available at the other end, there will be a voltage drop and the inverter will sign into

alarm mode. This will also happen if several machines are working on the same line or when the generator is underrated. In general,

our standard power cable can be doubled in length; if you need longer lengths then you must replace all the cables with cables of a

bigger gauge rate for the length and amperage.

8.2 DISMOUNTING AND MOUNTING TOOL HOLDER TO CHANGING V-RINGS AND FELT-RINGS

To check or replace the buffers and the elastic elements , the tool holders have to be dismounted.

You will need deep metric socket 13mm with outside diameter not more than 3/4in to unscrew the four bolts (Fig.8.2.1) and remove

the holder (Fig.8.2.2) When the tool holder is dismounted, you can change the sealers (V-Ring and Felt-Ring).

By loosening four Hex cap flange bolts (Fig.8.2.3) the adaptor comes loose. Unscrew the six screws of the cap (Fig.8.2.4) 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.8.2.5) just push the V-Ring so the top is on the same level as the pulley

top (Fig.8.2.6). Then take the adaptor and push the V-Ring down with the adaptor (Fig.8.2.7). 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.8.2.7).

Close the sealers with the cap (Fig.8.2.8) and screw the bolts. Always use the original bolts.

8.3 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.8.3.1) to dismount the retaining washer (Fig.8.3.2). Take out the screws on the buffers and the nuts of the

elastic element (Fig.8.3.3;Fig.8.3.4). Remove the elastic element from the QC plate (Fig.8.3.5). While the holder is dismounted

(Fig.8.3.6;Fig.8.3.7) clean the parts and replace the defective with new ones. Assemble the holder with new buffers with new screws

and new elastic element. Put the retaining washer (Fig.8.3.8) and push the locking pin (Fig.8.3.9). This will prevent the fall of the

washer when mounting the holder on the machine.

Figure 8.3.13

Make sure the four bolts holding the adaptor

(Fig.8.3.12) are reliably tighten. Mount the holder on

the machine using the same socket as mentioned in

8.2 (Fig.8.3.10;Fig.8.3.11). The retaining washer fits

into the central hole C of adaptor and the four bolts

into the thread holes Т (Fig.8.3.12). 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.8.3.2) 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.8.3.13 is 3-D section view of the holder,

showing its parts. The numbering is the same as in

Spare parts.

hose of the water sprayer(Fig.8.4.3). Lift the machine in position to change the tools.

Turn manually the holders in order to turn the main head, stop when you see through

the window the chain tensioner (Fig.8.4.4).

Loosen a quarter to 1/2 rev the two bolts of the chain tensioner (Fig.8.4.5) the tensioner should turn with minimum clearence,

without inclination, then unscrew the inner nut. To tension the chain screw the outer nut (Fig.8.4.6). The tensioner of the

planetary chain should allow chain sagging 3...5mm/1/8...3/16 in/ controlled in span X (Fig.8.4.7). When ready screw the two nuts

(Fig.8.4.6) and the screw(Fig.8.4.5).

ATTENTION: NEVER “OVER” TENSION THE CHAIN, THE CHAIN WILL BE DAMAGED

8.5 MOUNTING NEW PLANETARY CHAIN

The planetary chain is replaced with new one when the step/drive of the chain tensioner is finished or there is a break in the

integrity of the chain.

Unscrew the eight bolts (Fig.8.4.1) and take out the cover (Fig.8.4.2) and pull out the hose of the water sprayer (Fig.8.4.3). Lift

the machine in position to change the tools. Turn manually the holders in order to turn the main head, stop when you

see through the window the chain tensioner (Fig.8.4.4). Separate the carriage from main head, pull out motor plug (Fig. 3.1),

water tubes and vacuum tubes (Fig. 3.2) (Fig. 3.3). Take off handle (without water tubes) (Fig. 8.4.3). Release the pin sets (Fig. 3.4)

which attach the head to the carriage. Take off the weight holders(Fig. 8.5.1), machine support(Fig. 8.5.2) and the service window

tensioner(Fig.8.5.6). Pull out the split pin (Fig.8.5.7) and the chain link pin (Fig.8.5.8) (Fig.8.5.9). Take the chain, and put on the

same way the new chain, get in the chain link pin and the split pin (Fig.8.5.9) (Fig.8.5.8) (Fig.8.5.7).

Mount the chain tensioner (Fig.8.4.6). Screw the two screws (Fig.8.5.4)(Fig.8.4.5). Loosen a quarter to 1/2 rev the bolt of the chain

tensioner (Fig.8.4.5) the tensioner should turn with minimum clearence, without inclination, then unscrew the inner nut. To

tension the chain screw the outer nut (Fig.8.4.6) . The tensioner of the planetary chain should allow chain sagging

3...5mm/1/8...3/16 in/ controlled in span X (Fig.8.4.7).

When ready screw the two nuts (Fig.8.4.6) and the screw(Fig.8.4.5).

ATTENTION: NEVER “OVER” TENSION THE CHAIN, THE CHAIN WILL BE DAMAGED

8.6 REPLACING THE PLANETARY DRIVING CHAIN WHEEL AND PLANETARY TENSIONER

Check and repeat the instruction in 8.5 MONTING NEW

PLANETARY CHAIN.

Unscrew bolt pos.1 take the chain pulley pos.3 together with the

sealer pos.5. Change the sealer and mount it to the chain pulley

pos.3. Apply lithium grease on the shaft and mount back the

wheel and the front washer pos.2 as shown on (Fig.8.6.1). Screw

the bolt by using always the “blue” thread locking adhesive.

Tightening force of the bolts has to be 9...11N.m(6.6...8 ft/lbs).

8.7 TENSIONING AND REPLACING THE BELTS

The transmission of the machine has two timing belts (main belt and

planetary belt) of maintenance free type. 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. 8.7.1).

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

recommended.

Fig.8.7.5 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

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.8.7.5-2) (Fig.8.7.6) (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

To dismount the planetary belt (Fig.8.7.5-1) unscrew the screw of the front washer (Fig.8.7.7) and the two screws of the conical

sleeve (Fig.8.7.8). Screw one screw in the free thread(Fig.9.7.9), to push the washer down (Fig.8.7.10); take the conical sleeve and

the belt (Fig.8.7.11). You can help with a flat screw driver if the sleeve is not going out easy. (Fig.8.7.12).

Figure 8.7.5

Figure 8.7.6

Superabrasive User Manual Original Language Lavina® 25LM-X / Lavina® 25LM-X-HV 1/2016

The essembly is on reverse order, and is important to match the threads of the conical sleeve and the belt washer(Fig.8.7.13). Put

the front washer (Fig.8.7.14), 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.8.7.14)(Fig.8.7.15). 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.8.7.16).

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.8.7.17)(Fig.8.7.18). Dismount

the planetary belt (see 8.7.)

8.8 REPLACING THE PLANETARY DRIVEN CHAIN WHEEL

Dismount the planetary chain and the tensioner and see Fig.8.5(MONTING NEW PLANETARY CHAIN).

Dismount the tool holders, sealers and bottom cover see Fig.8.7(TENSIONING AND REPLACING THE BELTS). Unscrew

the cap that gives access to the fastening bolts of the driven chain wheel (Fig.8.8.1)(Fig.8.8.2). 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.8.8.3).

You will need magnetic deep metric socket 10mm with outside diameter not more than 11/16 in to unscrew the six

bolts (Fig.8.8.3)(Fig.8.8.4) (Fig.8.8.5).

Driven Chain Wheel is composed by two symmetrical halfs(Fig.8.8.6). Mount on the reverse order.

8.9 REPLACING THE PULLEY UNITS

Dismount guard, top cover, maintenance window chain tensioner, driven chain wheel, bottom cover and belts as previous

described.

Unscrew the four bolts of each pulley between the base plate and the motor base

disc (Fig.8.9.1)(Fig.8.9.2) and dismount the pulley (Fig.8.9.3).

A seal (Fig.8.9.4) should be placed on top of the pulley before mounting.

When mounting back secure with sealant (fig.8.10.3).

8.11 REPLACING PARTS FROM THE DRIVING OF THE CARRIAGE

Lift the lorry so both wheels are on the air. Unscrew the four bolts (Fig. 8.11-1) and take the bearing of the wheel (Fig.8.11-2).

From this position you can replace the loose key(Fig. 8.11-3) or the

sealing V ring (Fig.8.11-4) without dismounting other parts. If a

replacement of the half clutch is necessary (Fig. 8.10-5) unscrew the

four bolts (Fig. 8.11- 6). During reassembly you have to assure the

coaxiality of the wheel bearing against the hole of the half clutch (Fig.

8.11-5). Tighten the four bolts by hand (Fig. 8.11-1) and roll the bearing,

so there is no increase or reduce of resistance on rolling. (Plug the lorry

into the power supply, put switch SLOPE in pos. ON and tighten the

four bolts (Fig. 8.11-1) tightening torque - 45N.m. (this way the parts of

the electromagnetic clutch will take working position). After release of

the electromagnetic clutches (put switch SLOPE in position OFF and

activatе the button STOP the bearing should scroll easy, without

tangible resistance by hand. To replace the whole driving unit (Fig. 8.11-

7) or engine (Fig. 8.11- 9) unscrew the bolts (Fig. 8.11- 8). During

reassembly you have to assure the coaxiality between the driving unit

and the bearing of the two wheels.
