Annual Lubrication - Jet GHB-1330 Gebrauchsanleitung

This chuck has four independently
adjustable chuck jaws. These permit
the holding of square and
asymmetrical pieces and enable the
accurate concentric set-up of
cylindrical pieces.
7.7 Live centre (optional)
The live centre is mounted in ball
bearings.
Its use is highly recommended for
speeds above 500 RPM.
To eject the live centre, fully retract
the tailstock quill.
7.8 Steady and follow rest
(standard for GHB-1340A)
The steady rest
serves as a support for longer shafts
and ensures a safe and chatter free
operation.
The steady rest is mounted on the bed
way with a locking plate.
Tighten the fingers so that they are
snug but not tight against work piece.
Lubricate the fingers to prevent
premature wear.
The follow rest
is mounted on the saddle and follows
the movement of the tool. It prevents
flexing of long and thin work pieces
under pressure from the tool.
Set the fingers snug but not overly
tight. Lubricate the fingers to prevent
premature wear.
