CAUTION
- When attaching and detaching the file, turn off the power beforehand.
- After the file is locked in place, lightly pull out the file to make sure the file is locked.
- Always clean the shank of the file to be installed before use. Allowing dirt to enter the chuck could cause
loss of concentricity and deterioration of chucking force.
- Do not exceed the rotation speed recommended by the file manufacturers.
