G4002/3 Gear Head Lathes -9-
Chucks
The Model G4002/3 Metal Lathe comes equipped
with a 6'' 3-jaw chuck (already installed), a 8'' 4-
jaw chuck and a face plate.
The 3-jaw chuck is a scroll-type chuck, meaning
that all three jaws move in unison when adjust-
ments are made. The 4-jaw chuck, on the other
hand, features independent jaws. The 4-jaw
chuck is used for square or unevenly-shaped
stock.
The 3 and 4-jaw chucks have a D-1 Camlock
mount. Please note that there are lines stamped
into the cam and on the chuck body. A chuck key
is used to turn the locking cams as in Figure 2.
Mounting
This lathe should be securely mounted to a stand
or bench top. An accessory stand is available
from Grizzly, please see our current catalog for
pricing. There are 2 holes in the base at the tail-
stock end of the lathe and four holes on the gear-
head end which can be used to secure the
machine to a stand.
The lathe does not require a great deal of assem-
bly. This section details the installation of the var-
ious accessory holding devices. The following
section will familiarize you with the controls for
your new lathe. After you have completed both of
these sections we will do a test run of the
machine. Do not attempt a test run until you have
become familiar with both of these sections.
SECTION 4: ASSEMBLY & SETUP
DO NOT attempt to start this machine until
you have completed all of the assembly and
control familiarization steps. When per-
forming the assembly steps, ensure that
the switch is off and the power is discon-
nected. Failure to comply with this could
cause inadvertent starting of the machine
which can result in serious operator injury.
Lubrication
The G4002/3 is shipped from the factory pre-
lubricated. However, it is recommended that you
go through the entire lubrication sequence before
operating the machine. Review Section 7:
Maintenance for lubrication instructions.
Lubrication must be completed before you
start your new lathe.

ALWAYS place a piece of plywood over the
ways of the lathe before removing or
installing a chuck. This helps by covering
the sharp corners of the bed, protecting
your hands and fingers. Use extreme care
when removing or installing a chuck so
that your hands do not become trapped
between the chuck and the plywood.
