Grizzly G4003G owner manual Mounting Chuck Faceplate, Disconnect Lathe from Power

Mounting Chuck and

Faceplate

The Model G4003G is shipped with the 3-jaw chuck installed. This is a scroll-type chuck, mean- ing that all three jaws move in unison when adjusted.

The 4-jaw chuck, on the other hand, features independent jaws. This chuck is used for square or unevenly-shaped stock.

If either chuck cannot hold your workpiece, the cast-iron faceplate has slots for T-bolts that hold standard or custom clamping hardware. With the correct clamping hardware, this faceplate will hold non-cylindrical parts such as castings.

The chucks and faceplate 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 (Figure 19).

To protect the ways when removing or installing a chuck, ALWAYS place a piece of plywood over the ways. Use extreme care when removing or installing a chuck so that your hands do not become trapped between the chuck and the plywood.

To remove a chuck:

1.DISCONNECT LATHE FROM POWER!

2.Place a piece of plywood across the lathe ways and position it just under the chuck. The board should be at least 8" wide and 10" long.

The chuck is heavy and can be awkward to handle. Be aware that when removing or installing a chuck, your fingers can be pinched if you allow the chuck to drop.

3.Turn a cam with the chuck key until the cam line aligns with the spindle line mark shown in

Figure 20.

Always remove the chuck key after using it! Objects thrown from a lathe can cause serious injury or death to the operator or bystanders.
