Prepare the High-Pressure Lines for Repair

Before performing maintenance on the high-pressure lines, release all pressurized water.

1. Turn OFF the macine [1], if needed.

Figure 511  

2. Clean all high-pressure lines and components thoroughly before disassembly to remove all abrasive and debris.
3. Turn OFF the water, if needed.
4. Turn OFF the breaker power switch, if needed.
5. Make sure there is no pressurized water in the high-pressure lines.
a. Open the lid and lock it in the upright position.

Use care when opening or closing the lid to avoid injury. Never let the lid free-fall. Keep hand, fingers, or body parts away from the side of the table when closing the lid.

b. Loosen the Z-axis tubing clamp [1].

Figure 512  

c. Loosen the gland nut [1] to release the pressure; water can leak from the inlet body weep hole.

Figure 513  

d. Tighten the gland nut [1], if needed.
