WARNING! Lifting Hazard: Only use suitable lifting equipment, ensuring that it's on a stable, level surface. Never lift over people. Heavy loads could tip, fall, or shift unexpectedly, causing death or serious injury.
The TSC pump is approximately 400 lb (180 kg). We strongly recommend lifting it from the shipping pallet with an engine hoist. Due to the uneven weight distribution (one side is heavier), have an assistant help to guide and stabilize the pump during the lift to prevent tipping or injury.
Figure 1: Removing the TSC pump from the pallet.
Remove the pallet, and slowly guide the pump to the ground.
Unpack the shipping box with the remaining components of the TSC kit.

Install the Rotary Union
Remove the M6 screws that secure the right side panel of the spindle head cover using an M4 hex wrench. Loosen the two screws on the bottom (in slots). Remove the right panel and set it aside, along with all of the screws.
From the left side panel, remove only the M6 screws securing the front edge to the front panel of the spindle head cover with an M4 hex wrench.
Remove the screws on the top of the front panel with an M4 hex wrench.
Before removing the remaining screws on the front panel, snip off the cable ties holding the power drawbar button cable along the inside edge of this panel.
Remove the screws along the bottom front edge of the panel and lower the panel slightly to access the cable along the top left. Snip the cable tie holding this cable in place.
Disconnect the power drawbar button cable from the front panel by pressing in the connector's latch and removing it from the drawbar button.
Figure 7: Power drawbar button cable on the front panel.
Remove the front panel and set it aside, along with all of the screws.
Remove the retaining cap from the drawbar solenoid. Let the solenoid dangle, but temporarily replace the cap to avoid losing it.

Reinstall the drawbar solenoid and secure it with its original retaining cap.
Reconnect the air line into the power drawbar's push-to-connect fitting.
Install the High-Pressure Hose
The high-pressure hose is routed through the energy chain. To avoid damaging other cables, we strongly recommend removing several of the retaining covers from the chain. Gently pry up each cover with a flat-blade screwdriver and lift them off, continuing down the chain, including around the electrical connection cover. Set the covers aside.
Figure 13: Removing the covers from the energy chain.
Identify the high-pressure hose included with this kit. Route it through the energy chain channel, curving it to run towards the pump. Pull the loose end of the hose through the top section of the energy chain and pass it through the opening on the top right of the spindle, guiding it toward the rotary union.
Figure 14: Opening at the top of the spindle head cover.
Attach the end of the hose to the rotary union and tighten the hose nut with an open-end wrench. You may need to use a second wrench to hold the rotary union’s extension in place while tightening.
