The illustration shows the PulseJet hose routing on a VF-2: 1: Top View 2: Side View.

Route the nozzle air hose (1/4 inch black hose) from the CALM cabinet, through spindle head,  towards the PulseJet/PCool location.

Route the nozzle oil hose (5/32 inch clear hose): from the Oil reservoir, up onto the roof, into cable carrier, through spindle head, towards the PulseJet/Pcool location.

Route the Oil Reservoir air hose (1/4 inch clear hose) from CALM cabinet solenoid towards the Oil Reservoir location.

Note:  Make sure you leave enough slack at both ends.

Route the Oil Reservoir level sensor cable from the Oil Reservoir location, to the top of the roof to the electrical cabinet.

Note: Make sure you leave enough slack to connect the cable to the Oil Reservoir sensor.

Plug in the cable to the I/O PCB at P71.

Turn off air to the machine.

Locate the air manifold [1], remove the third NPT plug below the air gauge.

Install the adapter fitting P/N 58-1521 [2] into the manifold.

Install the solenoid valve [3] oriented as shown.

Connect the solenoid cable to the connector panel labeled "PULSEJET".

Unpack the PulseJet nozzle assembly.

Loosen the clamp screw [1] and slide the clamp and the PulseJet assembly onto the P-COOL nozzle.

Adjust the PulseJet nozzle so that the oil inlet fitting [2] is on the bottom. 

Aim the nozzle approximately at the spindle centerline (it will be adjusted later).

Tighten the clamp set screw.

Find the 1/4” black air hose [3] and connect it to the air fitting on the nozzle assembly.
Find the 5/32” clear oil hose [4] but DO NOT connect it to the oil fitting.  This hose will be connected during the prime procedure.

Mount the Oil Reservoir to the machine enclosure, refer to the illustration.

The oil resevoir assembly has magnets for easy mounting. 

Important: Do not slide the magnets on the enclosure. Instead, if you need to move the reservoir, tilt it to detach the magnets and then gently set it back down.

Connect the cable and air hoses to the Oil Reservoir assembly refer to the diagram.

Connect the air hoses to the solenoid. 

  Important: Make sure to connect the correct hoses to the solenoid, matching the color zip ties. If the hoses are swapped, it will send high pressure to the tank and could rupture the tank.

Slide the strain relief [1] into the slot on the reservoir assembly and tighten the retaining nut.

Apply the supplied spiral wrap [2] from the enclosure to the top of the machine to help neatly organize and secure the cables.

Make sure the drain valve on the bottom of the reservoir is in the closed (horizontal) position [4].

Remove the reservoir cap and fill the tank with oil [3].  Do not overfill the tank.
Note: The tank requires air space above the oil to maintain positive pressure above the oil.

Reinstall cap.

Make sure there is oil in the PulseJet reservoir and that the lid is tightly installed. Make sure the reservoir air and oil lines are connected. 

Disconnect the oil line [1] from the PulseJet nozzle and let it drape over a container placed on the mill table.

Press [DIAGNOSTIC] and navigate to the Maintanance then to the PulseJet tab [2]. 

Press [F4] to begin a priming cycle. Each cycle lasts 10 minutes.  The reservoir will be pressurized during the cycle. 

Note: Small machines may take only 1 cycle to fully prime the line. Larger machines may take 3 or 4 cycles. Heavier oils may take longer to prime. Continue running priming cycles until oil [4] begins to drip out of the oil line into the container. 

Note: While the machine is in the prime cycle the user can start a program.   However the user will not be able to start the prime cycle again while the program is running.

Reconnect the oil line to the PulseJet nozzle.

In MDI run:

M162 P10;
G04 P10.;
M30;

Test the PulseJet until a strong stream develops. 

To remove the pulsejet nozzle:

• Disconnect the air and oil lines.
  Note: Inspect the lines for damage or kinks, and replace them if necessary.
• Loosen the clamp screw [1] and slide the PulseJet nozzle out of the P-COOL nozzle.
  Important: Support the P-COOL nozzle while you loosen the clamp screw.

Unpack the PulseJet nozzle assembly.

• Loosen the clamp screw [1] and slide the clamp and the PulseJet assembly onto the P-COOL nozzle.
   Important: Support the P-COOL nozzle while you tighten the clamp screw.
• Adjust the PulseJet nozzle so that the oil inlet fitting [2] is on the bottom. 
• Aim the nozzle approximately at the spindle centerline (it will be adjusted later).

Tighten the clamp set screw.

Find the 1/4” black air line [3] and connect it to the air fitting on the nozzle assembly.
Find the 5/32” clear oil line [4] connect it to the oil fitting. 

Command 10-20 pulses until oil is properly streaming out of the nozzle.

 Note: If you are only replacing the nozzle (and not the tank) you do not need to run a full priming cycle.

Turn off air to the machine.

Locate the PulseJet solenoid [1].

Disconnect the two air lines [2,3] from the solenoid.

Important:  Mark the position of the two air lines, they will need to be installed in the same position.

Disconnect the solenoid cable from the connector bracket.

Remove the old solenoid and install the new one.

Connect the air lines to the solenoid.

Note:  The 1/4" clear line [2] attahced to the port with an orifice.  The 1/4" black line [3] connects to the port with no orifice.  

Connect the solenoid cable to the connector panel labeled "PULSEJET".

Turn on the incoming air and test the PulseJet.

Locate the tank [1] assembly on the side of the machine.

Place a large container [2] to drain the oil (at least 3 quarts).  

Note: if you plan to re-use the oil, the container must be thoroughly cleaned.

Open the valve [3] to let it completely drain. Loosen the tank cap to speed up the draining.

Once the oil is drained, close the drain valve.

Carefully lift the magnetic tank off the machine using a tilting motion. Turn the tank so that you can access the rear of the tank.

Carefully disconnect the air line [4] and oil level sensor [5].

Disconnect the oil line [6].

Note: Oil may flow back through the line, so have a container to place the line in to catch the oil.

Connect the 5/32" oil line [1], level sensor cable [2] and the 1/4"  tank air line  (see diagram).

Carefully install the tank to the side of the machine with the magnets.

Make sure the drain valve [4] is closed.

Open the tank cap and re-fill the tank with oil. Firmly replace cap until it “clicks”.

There will be air trapped inside the system from disconnecting and reconnecting the oil line. This air must be purged out before PulseJet can be used effectively. 

Refer to the Prime the Oil Line section in this document.

Make sure there is oil in the PulseJet reservoir and that the lid is tightly installed. Make sure the reservoir air and oil lines are connected. 

Disconnect the oil line [1] from the PulseJet nozzle and let it drape over a container placed on the mill table.

Note: Small machines may take only 1 cycle to fully prime the line. Larger machines may take 3 or 4 cycles. Heavier oils may take longer to prime. Continue running priming cycles until oil [4] begins to drip out of the oil line into the container. 

Note: While the machine is in the prime cycle the user can start a program.   However the user will not be able to start the prime cycle again while the program is running.

Reconnect the oil line to the PulseJet nozzle.

Test the PulseJet until a strong stream develops. 

The Haas PulseJet System is a programmable tap/drill oiling system that provides precise, controllable lubrication directly to the cutting tools that require targeted lubrication. This system pressurizes the oil tank that delivers the pressurized oil to the nozzle which is then pressurized and delivered to the cutting tool.

Remove the tank cap and check to see if the seal is in place. If it is out of position[1] or not visible[2], it will need to be reinstalled. Seal in the correct position[3].

Remove the tank cap and check to see if the seal is in place. If it is out of position or not visible, it will need to be reinstalled.

Use a flathead screwdriver to separate the cap assembly. There are four clips that hold it together.

Remove the ratchet plate and the cap seal and thoroughly clean all the components.

Reinstall the ratchet plate. It can only be installed one way. Reinstall the cap seal.

Press both pieces together until the clips snap into place.

Reinstall the cap and verify the PulseJet works correctly.

Make sure there is oil in the PulseJet reservoir and that the lid is tightly installed. Make sure the reservoir air and oil lines are connected.
