Connect the high-pressure braided hose [3] to the check-valve assembly [3]. The hose [3] is in the service kit.

 Note: If the hose [3] is too short, use the 90 degree fitting (P/N 58-3618) and the 45 degree fitting (P/N 58-3613). Disconnect the hose [3] from the bearingless TSC union. Connect the (2) fittings on top of the bearingless TSC union. Connect the hose [3] to the fitting assembly.

Connect the 1/4" tube [4] for the TSC purge solenoid to the check-valve assembly. The tube [4] is purple.

Connect the air-purge tube [5] to the check-valve assembly. This is the tube [5] that was disconnected from the reducer fitting. The tube [5] is black.

If the dome plugs [1] are near the front of the spindle:

Remove the dome plugs [1] from the bottom cover for the spindle. This is where you attach the vacuum generator.

Connect the vacuum-drain hose [2] to the vacuum generator. Use a hose clamp [3].

Connect the vacuum-generator tube [4] to the vacuum generator.

Move the vacuum generator [5] down into the space between the spindle cover.

Attach the vacuum generator [5] to the spindle-head cover. Use a 1/4-20 x 1/2" flanged button-head cap screw (FBHCS) [6].

If the dome plugs [1] are near the rear of the spindle:

Remove the dome plugs [1] from the bottom spindle-head cover. This is where you install the vacuum generator.

Remove the bottom spindle-head cover [2].

Install the vacuum generator [5] on the bottom spindle-head cover [2]. Use a 1/4-20 x 1/2" FBHCS [7].

Connect the vacuum-drain hose [3] to the vacuum generator [5]. Use a hose clamp [6].

Connect the vacuum-generator tube [4] to the vacuum generator [5].

Install the bottom spindle-head cover [2].

Install the assembly for the TSC-vacuum solenoid [1] in the upper manifold port. The assembly has a gray-cable tie.

Install the assembly for the TSC-purge solenoid [2]. The assembly [2] has purple cable ties.

Find the tube cap on the 1/4" gray tube [3]. Remove and discard the cap.

Trim the tube [3] to the correct length. Connect the tube [3] to the air regulator.

 Caution: Always trim tube ends at a 90-degree angle. This prevents a bad connection. If you cut the tube end at an angle, the tube does not make a good connection. A bad connection causes insufficient air pressure. Insufficient air pressure causes a malfunction.

Remove and discard the cap from the 1/4" TSC purple tube [4]. Trim the tube [4] to the correct length. Connect the tube [4] to the left fitting on the solenoid [2].

Operate this code in MDI mode:

M59 P1148 ;

G04 P5.0 ;

M69 P1148 ;

G04 P2.0 ;

M99 ;

P1148 is for inline spindles.

For HS machines, use P1124 and not P1148.

For belt-drive spindles, use P1120 and not P1148.

If the machine has a bearingless union, the union moves up and down at 7-second intervals. The up and down movement is small.

The illustration shows the up and down movements for these machines:

1. 40-Taper
2. 40-Taper (CALM)
3. 50-Taper

Push [RESET].

Push [AUX CLNT] to activate the TSC.

Inspect the TSC hoses for leaks.

Correct operation is as follows:

1. Coolant [1] flows correctly from the spindle.
2. A few drops flow from the vacuum-generator hose [3].

Push [RESET].

Put a TSC toolholder [2] in the spindle.

Push [AUX CLNT] to start the TSC.

Correct operation is as follows:

1. Coolant flows correctly from the spindle [1].
2. A few drops flow from the vacuum-generator hose [3].
