The more friction there is in your slideways, and the more performance you want to extract despite that friction, the more you need an automatic lubrication system. Automatic Way Oilers keep the friction consistent so the machine can be tuned to deal with it. They also reduce the wear and tear on your machine's ways.

In contrast to closed-circuit hydraulic systems, suction filtration is not a recommended filtration method with open-circuit pumps. This is due to the potential for high inlet vacuum to occur. Instead, a screen is recommended in the reservoir covering the pump inlet. A 125 µm (150 mesh) screen protects the pump from course particle ingression.

The wand is a high-pressure remote hydraulic cylinder that is plumbed to a footswitch-activated pump. After the fixture is cleaned of debris and the operator mounts a new part, a shut-off valve—located in the circuit just after the fixture-mounted booster—is opened. The operator then inserts the wand into the booster.
