Saddle Gib - Grizzly G4003G Owner's Manual

Compound Rest Gib
Figure 112 shows the gib location on the com-
pound rest. The compound rest gib adjusts in
the same manner and with the same tools as the
cross slide gib. However, in this case, to increase
or decrease tension, the gib adjustment screw
directions are reversed.

Saddle Gib

Before making adjustments to the saddle gib,
make sure that the carriage lock (see Figure 113)
is loose by turning it counterclockwise one full
turn.

Lock
The saddle gib is located on the bottom of the
back edge of the slide (see Figure 114). This gib
is designed differently than the cross or compound
slide gibs. Instead of being a wedge-shaped plate,
it is a flat bar. The gib pressure is applied by four
set screws. Hex nuts secure these set screws in
place, so they will not loosen during operation.

—To loosen gib, loosen set screws.
3. Move carriage back and forth and repeat
adjustments as necessary until gib pressure
is acceptable.
