The following service video shows how to install the PulseJet System on VMC and UMC machines.

 NOTE: This service video is for reference only and does not replace the written procedure.

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 adapter then connect the adapter to the connector panel labeled "PULSEJET".

 NOTE: If installing on a machine that has the CAN Lube Rack, do not use the air/lube solenoid cable adapter (33-0596). Instead, plug directly into the connector labeled 'PULSEJET" on the CAN Lube Rack.

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 reservoir 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 Maintenance 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.
