1.   Saw Blade Lubrication System.

1.1.          The standard LUNA saw blade lubrication system consists of a 1 litre spray mist container with fine filter, an automatic air activating switch and a venturi spray mist valve with inbuilt shuttle valve.

1.1.1.               Installation description:

1.1.2.               The automatic air activating valve is normally an open 3/2 valve that needs to be mounted so that the plunger is depressed if the saw is in the rest position.                              

1.1.3.               The venturi spray mist valve is mounted as follows.

1.1.3.1.        On Luna drop saws the venturi spray mist valve is mounted on the top saw blade cover behind the retractable saw blade guard; When the saw head is pulled down. One hole is drilled right in the centre area of the saw blade for the spray mist nozzle and one mounting hole is drilled and tapped metric thread M4. In the saw blade lubricating kit the venturi valve is supplied with a M4 screw, two air line fittings and pneumatic air hose.

1.1.3.2.        Saws saw like the ELU drop saw do come with a spray mist system that uses a bent extended nozzle. To replace the ELU system, remove the ELU lubrication system and fit the LUNA venturi valve onto the same holding plate. Extend the venturi spray mist nozzle with short section of air line (6mm).

1.1.3.3.        On table saws or up stroking saws mount the venturi valve so that the spray mist nozzle is pointing into the saw gap with the rotation of the saw blade into the direction of the aluminium extrusion that needs to be cut.

1.1.4.               The spray mist container with fine filter needs to be fitted below the venturi spray mist valve.

 2.   Material clamping system; horizontal.

2.1.          The material clamping system on drop saws uses the same automatic air activating valve that is used for the saw blade lubrication system.

2.2.          If the saw does not utilise a saw blade lubrication system fit the automatic activating valve first (see above description).

2.3.          To retro fit the pneumatics for the pneumatic clamping cylinders cut into the line that connects the automatic activating valve to the venturi spray mist valve. Insert in the line cut section a T fitting that is also supplied with a 6mm hose adaptor. The spray mist lines utilise 4mm air line and the clamping system is using 6mm pneumatic air lines. 

2.4.          Most LUNA saws are supplied with holes or threaded hole on the front of the saw base. Mount the mounting block utilising the provided holes. If no mounting holes are on the saw drill and tap holes (see separate instructions for your saw type – if required).

2.5.          Mount the clamping cylinder holders onto the blocks with the provided hand levers.

2.6.          Connect the air lines onto the automatic air activating valve.

2.7.          For fragile aluminium sections like fly screen the clamping system can be equipped with a compressed air pressure regulator. The pressure regulator is fitted into the 6mm air line before the clamping cylinders. It is best to mount the pressure regulator so that it can not be damaged by extrusion handling.

2.8.          The clamping system can also be equipped with shut off valve to disable the clamps if required.

2.9.          The system can have a central shut off valve that disables both clamps or it can be equipped with individual valves that disable a clamping cylinder as required.

 3.   Air Dust Gun.

 3.1.          The air dust gun is connected directly with the air supply to the saw. If the saw utilises a pneumatic air lubricator it is best to T the air line before the air lubricator.

 4.   Material clamping cylinders, vertical. 

4.1.          One or two vertical clamping cylinders are sometimes used on drop saw (standard on up stroking saws) for extrusions that tend to kick up during cutting (like security door extrusions).

Note to security door extrusion clamping:  The security door extrusion inner side that is usually pushed against the saw fence tends to kick up during vertical clamping. This is caused by the outer upper rip of the extrusion which is higher then the inner rips that support the security mesh. The claming cylinder is pulled up because there is no support for the clamp pad in the centre of the outside of the extrusion and the clamp force is applied about 20mm above the saw table onto the upper rip which is about 19mm high.

The best way to overcome this problem is to shape the clamping pad so that the security door extrusion is clamed in the middle of the outside extrusion.

Vertical clamps are used to ensure that the extrusion is flat on the saw table and does not move so that perfect mitres are cut.

If the saw is used to cut a mix of window door and other extrusions, an insert that slides into the outside gap between the two outside rips of the security door can be used.

4.2.          The vertical clamping cylinder air line is connected to the to the air line of the horizontal air line with a T connection. If the system is equipped with a pressure regulator, the connecting is usually made in the line that connects the pressure regulator and the horizontal material clamps.

4.3.          The vertical clamps are usually equipped with a shut off valve so that they can be isolated if they are not in use.
