For optimum performance from your chuck, follow the maintenance schedule below, and never hammer on the chuck, jaws, or a workpiece clamped in the chuck. Never subject the chuck to abrasives, flame, or water.
Daily:
•Check/correct loose mounting bolts.
•Use a vacuum, rag, or brush to clean the chuck after use. Never use air pressure to clean chips away from a chuck.
•Wipe the chuck down with a thin coat of way oil to prevent surface rust.
•Grease the chuck fitting with one to two pumps of NLGI #2 grease.
If the chuck ever becomes stiff to operate, it may have been contaminated with metal chips or abrasives from neglect or poor service practices. The chuck must be dissembled, cleaned, and re- lubricated.
To disassemble the chuck for a full cleaning and lubrication service:
