NOTE:
The words of "gripping force" and "clamping force" are used as a synonym in this
instruction manual.
Both words mean total force of clamping each jaw in a chuck.
Lubricate the chuck periodically.
Failure to lubricate the chuck may remarkably shorten the lifetime of the
chuck.
For all the chuck parts including consumables, place an order with
Howa Machinery, Ltd.
Howa shall not be liable for any accidents caused by use of parts not
supplied from Howa. Any and all warranties are invalid unless only
Howa’s genuine parts are used.
Use eyebolts when mounting or removing the chuck.
(Use the suspender belt when handing a 6-inch chuck, and eyebolt
when handling an 8-inch chuck.)
Otherwise, you may drop the chuck or suffer from lumbar injury due to
excessive load.
