I am having a foaming problem, what do I need to do?

Generally, synthetics and semi-synthetics will foam a little. The key is to pay attention to the dilution ratio. Too much lubricant in the ratio will produce foaming—reduce the ratio of coolant and increase the ratio of water. Too little lubricant in may cause your pump to cavitate, also causing a foaming issue—increasing the amount of lubricant in your pump should solve this issue.

I am having a rusting problem, what do I need to do?

Rust can be caused by not having enough lubricant in the mixture. If your dilution ratio is correct and rust is still forming, you may be using the wrong lubricant/coolant for the specific job at hand.

What dilution ratio is best to use?

Typically, metal working fluids have a dilution range between 5:1 and 25:1. Grinding is best with a ratio of 20-25:1, machining 5-15:1 (depending on the metal and which lubricant is used), and sawing 5-15:1 (depending on the metal, and which lubricant).

I don’t know the size of my sump, how can I figure it out?

To estimate the size of your sump, you may use the following equasion: L x W x H x .004329.

How long will coolant last in the sump?

With regular maintenance, you can expect your coolant to last through your next cleanup. A recommended maintenance schedule would be every 3-4 months.

How do I clean my machine and sump?

Extreme Kleane, machine and sump cleaner, diluted to the specifications on the label, and added to the sump will keep your machine clean. After adding the Extreme Klean, let the machine run 15-20 minutes and drain. Wipe the sidewalls of the sump, with cleaner, add new lubricant and run your machine. Oil absorbent pillows and booms will also keep your sump clean. You should clean your machine sump at a recommended maintenance schedule every 3 to 4 months.
