Grizzly G0561 owner manual Cutting Fluid, Biological Poison Hazard

FIRE HAZARD! DO NOT cut magnesium when using oil-water solutions as a cutting fluid! Always use a cutting fluid intend- ed for magnesium. The water in the solution will cause a magnesium-chip fire.

4.Adjust the valve on the coolant hose to control the flow of coolant (see Figure 29). Make sure that the pressure is not so high that coolant spills on the floor and creates a slipping hazard.

5.Turn the pump toggle switch ON before mak- ing your cut.

NOTICE

Keep the tray chip screen clear so coolant can recycle to the pump reservoir. NEVER operate the pump with the reservoir below the low mark or you will over-heat the pump and void your warranty!

Cutting Fluid

While simple in concept and function, many issues must be taken into account to find and use the correct cutting fluid. Always follow all product warnings and contact the fluid manufacturer for unanswered questions.

Use the selections below to choose the appro- priate cutting fluids:

•For cutting low alloy, low carbon, and gen- eral-purpose category metals with a bi-metal blade—use a water soluble cutting fluid.

•For cutting stainless steels, high carbon, and high alloy metals, brass, copper and mild steels—use "Neat Cutting Oil" (commonly undiluted mineral oils) that have extreme pressure additives (EP additives).

•For cutting cast iron, cutting fluid is not rec- ommended.

•For cutting magnesium, use only cutting fluid that is designed for cutting this material.

Remember: Too much flow at the cutting fluid nozzle will make a mess and can make the work area unsafe; and not enough fluid at the cut will heat the blade, causing the blade teeth to load up and break.
