3. PREPARING FOR OPERATION

3.1. Setting-Up the MA Dispensers for 1st usage The MA Dispensers are versatile machines and are usable for a wide range of applications. The following section covers the setting-up of the unit to suit your application.

CAUTION Make sure all health & safety instructions recommended by the adhesive or sealant manufacturer are strictly observed

Preparation prior to first use:

Packing: - Remove machine from the box.

o Only the front plate needs to be removed from the box

- Remove all plastic protection parts from the machine that protected the machine while shipping

Placing:

- Place the machine in an area you want to use it. Make sure you have

enough space in the front of the machine to dispense, and in the back to refill the tanks after they are empty.

- The machine comes with adjustable feet and thus is can be leveled. o The MA dispenser usually stands on a table. It comes with the

adjustable feet.

Assembly:

- Add the crank handle which was delivered with the machine to the crank shaft and tighten the nuts with the small L-Wrench that came with the machine.

Note:

1. The MA dispensing machines will need to be ratio set before 1st usage (Refer to 3.3.Setting up the Ration and the Appendix A in this manual).



3.2. Initial flushing of the pumps

CAUTION Before attempting to fill the MA Dispenser, the operator must first read and understand this Instruction Manual.

CAUTION Before the 1st usage or when being used with another adhesive the pumps MUST be flushed out with the new resin/ hardener. This material MUST NEVER be used to actually make products, but thrown away into the according chemical waste according to safety procedures.

- Make sure the dispensing trigger is turned to the closed mode. - Open the Resin Tank lid. Keep the screen in the tank down to make sure

any dirt in the resin drum will not be filled in the tank.

- Fill in Resin app. 500gr of Resin (Component A) in the left Resin tank. - Fill in Hardener app. 500gr of Hardener (Component B) in the right

Hardener tank.

- After the resin and hardener are filled in, close the lids. Do not tighten the lids while dispensing.

- Attach the extra tubes to the valves and place the ends of the tubes into the

corresponding container in the re-fill holes (Resin to Resin tank, Hardener to Hardener tank.)

- Open the dispensing trigger and turn the crank handle thus start dispensing

and cycling (by opening the valves) app. 5min. This makes sure the Pumps are securely flushed and cleaned off any friction pump oil that might still be inside the pumps.

- Close the dispense trigger and take off the tubes from the valves and the

tanks. Clean them for later use.

- Dispense the complete amount of the flushing material and empty the machine completely while letting it run dry for a few seconds. Initial flushing of the pumps is now completed

NOTICE This process is the same when changing the adhesives. Do not flush the pumps with solvents.

. CAUTION After any kind of flushing the machine MUST be initially as described in Chapter 3.3.



3.3. Initial filling of the tanks

Note:

1. For filling the containers adhesive or sealant components, a RESIX Refill Station is not required (not included), but will be easier to do.


- Make sure the dispensing trigger is turned to the closed mode. - Open the Resin Tank lid

- Fill in Resin in the left Resin tank until it full. Do not fill more resin than the

outside level indicator can show. If the level indicator shows full, it means the tank is full.

- Fill in containers to maximum level.

- Do the same with the smaller Hardener tank.

CAUTION Always concentrate while filling resin or hardener into the tanks. Stop refilling before the tanks are too full.

- After the resin and hardener are refilled, close the lids. Do not tighten the

lids while dispensing. - Attach the extra tubes to the valves and place the ends of the tubes into

corresponding container (Resin to Resin tank, Hardener to Hardener tank)

- Dispense and cycle app. 2,500gr of mixed components to make sure there is not air coming out while dispensing.

Initial filling of container is now completed.

NOTICE Once the containers are filled, it is essential that the unit never run out of components. If one components container is fully depleted the initial filling procedure has to be repeated.



3.4. Setting-Up a new Ratio

NOTICE Check with your sealant & adhesive manufacturer to ensure the correct ration by weight of 2 components.

Note:

The ratio set-up will take some getting used to and is usually a process to adjust the correct sprockets to fit your work environment.

1. Open the technical box with the key supplier with the machine.

2. Prepare the tools needed for this operation on the open door ([a] screw wrench, [b] L-Wrench, [c] sprockets)

3. Loosen the 2 nuts on the Pump B just enough that it can be moved

4. Move Pump B to the left, just enough that the chain can be detached.

5. Use the L-Wrench to loosen the 2 nuts in the back of the Sprocket-B

6. Take out the old Sprocket-B

7. Attach the new Sprocket-B on the shaft. Take care that the 2 nuts are

matching the 2 straight areas on the shaft

8. Tighten the 2 nuts on the Sprocket-B with the L-Wrench

9. Attach the chain over the new Sprocket-B

10. Move the Pump-B to the right to tighten the chain just enough to still have some room (max. 5mm)

11. Tighten the 2 Pump-B nuts

12. Test the ratio by measuring the weight of each component (make sure

the cup weight is deducted and the scale is correct)

3.5. Converting to a different type of Adhesive or Sealant This process is the same as the process described in Chapter 3.2. Initial flushing of the pumps. Please refer to this Chapter when changing to another adhesive.



4. OPERATION

WARNING Never use the MA Dispenser inside or around electrical equipment.

4.1. Regular re-filling of the tanks

Note:

1. For filling the containers adhesive or sealant components, a RESIX Refill Pump is not required (not included), but will be easier/cleaner. Contact your RESIX dealer for more information or check www.resin-mixer.com


- Make sure the dispensing trigger is turned to the closed mode.

- Open the Resin Tank lid.

- Fill in Resin the Resin tank until it is full. Do not fill in more resin than the

outside level indicator can show. If the level indicator shows full, it means the tank is full.

- Fill containers to maximum level

- Do the same with the smaller Hardener tank

- Close the cover before you fill the next Tank

CAUTION Always concentrate while filling resin or hardener into the tanks. Stop refilling before the tanks are too full.

NOTICE Once the containers are filled, it is essential that the unit is never run out of resin components. If one component container are fully depleted the initial filling procedure (described in Chapter 3.1.) has to be repeated.



4.2. Regular re-filling of the tanks Note:

The MA Dispensers can work only when you open. Opening and closing the dispensing trigger to dispense components in the correct ratio. For the MA Dispenser the minimum shot volume is 10 ml.

4.3. Stand-By and Storage

CAUTION Upon completion of dispensing operation and for safety reason, disconnect the power supply for longer pauses.

- During short breaks and holidays of up to 2 weeks it should be safe to keep

the adhesive inside the tanks. Please check with your adhesive supplier for more information.

- Upon re-starting the machines the hardener tank needs to be checked and possibly cleaned slightly (the tanks are not air-tight 100%).

- During longer periods of pauses (longer than 2 weeks) it is recommended to dispense both components back into its original containers for longer storing. This can be done with the original extra tubes attached to the valves. Place the corresponding tubes into the correct drum and start the machine, until it runs dry.

- Close the valve and use a squeegee to get all the liquid into the bottom hole.

Note:

- In case of re-starting the dispensing machine, please start capital 4.1. Initial Filling of the Containers. In case you are going to use a new component system, please go to chapter 3.2. Initial flushing of the pumps

CAUTION Do not use Acetone or other strong cleaning chemicals inside the tubes and pumps frequently. This can destroy the sealers and make the pumps or tubes leak.



5. MAINTENANCE AND REPAIR

NOTICE All maintenance and repair work must be carried out by qualified and properly trained personnel only. When handling, maintaining or repairing the equipment, personnel are expected to use safe engineering and health and safety practices at all times.
