Once the packaging has been opened, remove the fixing stops from the feet of the machine

Remove protections before connecting the machine

5.INSTALLATION

5.1.Machine placement

Before any work make sure that the machine is well aligned and does not oscillate at any of its ends, in which case it must be wedged to avoid movements. For its correct level it is necessary to use a leveling tool. This check must be carried out both longitudinally and transversally.

Poorly leveling the machine can cause unwanted vibrations and premature wear of the linear guides.

Before connecting it, remove all packaging protections that the machine has for transport.

Control panel operation

6.STARTING UP

In this section we show you to operate the ELITE SVG 850 in order to work.

NOTE: The data that appears in the different images are by way of example, each type of tool has its recommended data and a skilled operator must know them.

Emergency stop

It's the round red button. In the event that there is a failure in use or a dangerous situation is being created, it allows the immediately disconnection of the machine.

Should not be used unless strictly necessary.

Once used, to use the machine again, you must pull it to return to the initial position, additional referencing and setting up must be needed.

Sharpening operation

To start the sharpening process, you must first make sure that the emergency stop button is not activated.

SVG 850 Set up

6.1.Machine power on and axis homing

Turn on the machine setting the main switch in the ON position, deactivate the emergency stop in case it is active.

The machine screen turns on and the green light of the indicator lamp lights up indicating that machine is now powered.

Now check that no axis will collide with the grinding wheel to start the homing process.

Then close the cabin door and press the start button (START) and follow the instructions on the screen.

IMPORTANT: Do not open the cabin door while the machine is homing. If you accidentally open it, turn the machine off and repeat the process.

Once the machine has finished referencing it is ready to work and the working menu is shown in the LCD screen.

6.2.Changing the grinding wheel

Necessary tools: Fixed wrench No. 17.

With the machine switched off, remove the hex screw from the bottom of the grinding wheel. Hold the wheel and wheel holder ring throughout so that it does not fall.
Now insert the new grinding wheel.
Reposition the locating ring in the correct position so that the locating pin passes through the locating ring.
Replace the hex bolt and tighten.

6.3.Changing the saw holder

The ELITE model SVG 850 sharpening machine comes equipped with two (2) saw blade supports. One up to ø850 mm and another support for small saw blades <ø200 mm..

To exchange the supports, remove the two (2) screws and save them. Now we have the support outside. It is important to make sure that when the support comes out, the centering pin remains in its position. When the 10 mm centering pin wears out due to using, it will be necessary to be exchanged for a new one.

Next, place the other saw blade support, and make sure to fix it again. Now, the centering pin itself limits the diameter that we can put on the saw blade.

The mounting of the saw blade is the same as with the other support: use a centering ring and now we can mount the saw blade to be sharpened. It is ready to work.

6.4.Adjustment of the indexing feed cam according to the diameter of the circular saw

Depending on the diameter of the blade, the indexing feed cam will need to be adjusted in order for the indexing pawl to advance the teeth of the saw.

NOTE: To adjust the indexing feed cam the indexing feed pawl must be in its lower position. Otherwise the force of the spring will move the indexing pin to the lowest position and we will lose the current position.

7.WORK OPERATION

7.1.Sharpening the top of the tooth

To approximate the grinding wheel to the top of the tooth, once we have verified that we have placed the appropriate grinding wheel for sharpening the top or external part of the tooth, we should go to the last screen of the working program and press the START button. An informative message will appear on the screen, the machine will ask to start spinning the grinding wheel. If we press the START button again the machine moves so you can now set the initial grinding points.

Next, we have to close the clamp by pressing the clamping button of the control panel (see control panel picture to locate the button). Then we can press the feed pawl movement button to verify that we are in the correct tooth, as requested by the machine set up screen, and then we should move the indexing pin away, to avoid collision from the grinding wheel. At this point, we should follow the guide in the LCD screen menu to follow the instructions to touch the grinding wheel with the tooth.

From here, we can move the axis using the movement buttons of the control panel, to approach at fast speed or, if we press the menu selector once, at slow speed.

To begin the approximation, start the movement with the fast speed selected, once the grinding wheel is quite close, then select the slower speed to do the fine approximation phase until we gently touch the tooth with the grinding wheel. Always with visual support.

Once the grinding wheel is in contact with the tooth, we must raise the stone to the point where sharpening phase will begin. At this point, press the START button to confirm.

The machine prepares for the second point if needed, the help menu in the LCD screen will inform us: there are saws that, due to their tooth geometry, only need one setting point and there are others that require two.

7.2.Sharpening of the tooth face

To proceed to approximate the grinding wheel to the tooth face or internal part of the saw blade tooth, make sure to select the appropriate program for face grinding in the LCD of the control panel screen.

Once we have the correct parameters entered in the program, we press SAVE in the LCD menu to save the program. Next, we press the START button. A warning message indicating the the grinding wheel will start to spin will appear on the LCD screen. (this is an informative message that warns us of the danger of being close to the grinding wheel). After this, we press the START button again. We will see how the machine is prepared for the sharpening process and the grinding wheel starts to spin.

At this point, using the direction arrow buttons will allow us to move the axis, we will be able to approximate the grinding wheel at a fast speed. If, on the other hand, we want to select slow speed, we will press the white selector once. We can move the axis that we require to move.

This allows us to make the initial approximation with the fast speed.

NOTA IMPORTANTE: at this point, it is important to make sure that you have the jaw closed and the tooth to be sharpened is the correct one.

Once we are close to the tooth, we will change the speed to slow on the menu screen using the white selector.

Now we gently touch the grinding wheel with the tooth, then we should move the grinding wheel up to the point of the internal part where we want the sharpening process to stop. It is at this point where the sharpening will end.

Once we have the approximation process finished, we press the START button again and the sharpening cycle will begin to run.

8.MAINTENANCE

8.1.Preventive maintenance

The maintenance of the ELITE model SVG 850 grinding machines is very simple but at the same time important.

It consists of the following:

• Cleaning of the carriage guides - Daily
• Cleaning and greasing the polished parts, in case the machine is not used for several days, to prevent oxidation.
• Check the level of coolant in the coolant tank. You can use to refill the coolant the ELITE SintoCut PRO MIX. The coolant should be mixed with water between 2 and 8%. Being below it can lead to oxidation of mechanical parts and if the level is higher it can be toxic. - Monthly.
• The sludge and dirty that is deposited both in the work area and in the coolant tank must be emptied - Weekly.
• Keeping the machine clean and in good condition will allow for optimal long-term use.

Use the equipment only in dry environments. The temperature must be between 5 and 40ºC. A relative humidity greater than 90%, as well as a saline environment, would cause premature corrosion of the machine.

To lubricate the pneumatic circuit we recommend using Esso Spinesso oil.
