How to Clean Up Coolant Spills in the Metalshop

Guidelines

  1. Ensure that there is coolant in the tank and that the coolant is flowing when you turn it on.
  2. If there is no coolant flow ensure that there is enough coolant in the tank. Add more if necessary without overflowing the tank.
  3. Clamp the work in the vice securely.
  4. Use the slow speed (1) for cutting ferrous materials and fast (2) for non-ferrous materials.

Cutting Capacity

Blade Removal

  1. Turn off the power to the tool
  2. Remove the thumbscrew for the blade guard mechanism. This is to allow you to hold the blade later.
  3. Use the large socket (on the shelf under the tool) to undo the large nut holding the blade on. This is a REVERSE thread!
  4. Remove the nut and mounting plate and remove the blade. Note: the blade may be very sharp!
  5. Do not loose the nut and plate. If not replacing the blade then re-mount these to the tool.
  6. Replace the large socket to the shelf under the tool!

Note: The internal hex bolt in the middle of the spindle need not be touched while removing the blade. This is for the clutch mechanism.
