Assembly and Operation
ATTENTION!
Before starting cleaning and assembly work, switch
off the machine and disconnect the mains plug.
7.1 Mounting and securing the chuck to the
wood lathe spindle
To mount the four-jaw chuck on the spindle of the wood-
working machine, carefully screw the adapter and the
chuck onto the spindle until it stops. Place the lever (A,
Fig. 2) in the hole of the jaw chuck and the second lever
in the spindle flange hole as shown in Fig. 2. To secure
the chuck, turn the two levers clockwise until the adapter
face (B,Fig.2) contacts the spindle flange (C, Fig. 2). To
release the chuck, turn the levers counterclockwise.
Opening and closing the clamping jaws (D,Fig. 2) also
requires both levers (A,Fig. 2). Place one lever in the
hole (E,Fig. 2) and the second lever in the chuck hole. To
open the jaws, turn the two levers counterclockwise. To
close the jaws, turn the levers clockwise.

7.2 Changing the chuck jaws
To change the standard chuck jaws already mounted to
the outer jaws, loosen the 2 cap screws (A,Fig.3) which
fix each jaw to its jaw base. Take the outer jaw with the li-
miting pin (B, Fig.3) and position it either on jaw base 2
or 4 (C, Fig. 3). The limit pin (D, Fig. 3) engages in the
slot (E. Fig. 3) in the chuck body.
This prevents the positioning of the outer jaw on jaw
base 2, so that the jaws do not protrude from the chuck.
Check the jaw numbers against the jaw base numbers
and secure the outer jaws with only 1 cap screw per jaw.

7.3 Clamping a workpiece in the chuck
To clamp a workpiece in the chuck, open the clamping
jaws. Position the workpiece in the center so that the
jaws are evenly distributed on the workpiece. Tighten
the jaws enough to prevent the workpiece from slipping
or twisting.
7.4 Removing the adapter
If necessary to remove the adapter, loosen and remove
the 3 cap screws that secure it. Screw 2 of the cap
screws into the 2 previously unused threaded holes in
the adapter. These two cap screws lift the adapter by
tightening the two screws one by one until the adapter
slowly loosens.
