Adjustments - Jet GH-1340W Owner's Manual

Compound Rest
The compound rest is located on top of the
cross slide and can be rotated 360 degrees.
Loosen the two socket head cap screws (A,
Fig. 21) on the compound rest base. There is
a calibrated dial (in degrees B, Fig. 21) below
the rest to assist in placement of the
compound to the desired angle.

Adjustments

After a period of time, wear in some of the
moving components may need to be adjusted:
Saddle
1. Locate four hex nuts found on the bottom
rear of the cross slide and back off one full
turn each.
2. Turn each of the four set screws with a
hex wrench until a slight resistance is felt.
Do not over tighten these screws.
3. Move the carriage with the hand wheel
and determine if the drag is to your
preference. Readjust the set screws as
necessary to achieve the desired drag.
4. Hold the socket set screw firmly with a hex
wrench and tighten the hex nut to lock the
set screw in place.
5. Move the carriage again and adjust again
if necessary.
Note: over adjustment will cause
excessive premature wear of the gibs.
Cross Slide
If the cross slide is too loose, follow procedure
below to tighten:
1. Loosen the rear gib screw (not shown)
approximately one turn.
2. Tighten the front gib screw (B, Fig. 22) a
quarter turn. Turn the cross slide
handwheel to see if the cross slide is still
loose. If it is still loose, tighten the front
screw a bit more and try again.
3. When the cross slide is properly adjusted,
tighten the rear gib screw.
Note: over adjustment will cause
excessive premature wear of the gibs.
Compound Rest
Follow the same procedure as the cross slide
adjustment to adjust the compound rest. Rear
gib screw is shown (A, Fig. 22). Front gib
screw (not shown) is by the handwheel.
