Adjustments; Fence Stop Adjustments - Jet JPJ-12B Operating Instructions And Parts Manual

Figure 7
Cutterhead Guard
Refer to Figure 8:
Properly positioned, the cutterhead guard (B)
should rest against the fence (A).
Fence Movement
Refer to Figure 8:
The fence (A) can be moved forward (C) or
backward (D) across half the width (W) of the
table, with 6" travel. It also tilts up to 45°
backwards (E) and has positive stops at 90° and
45° R.
When edge jointing, the fence assembly should
periodically be moved to different positions to
distribute wear on the cutterhead knives.
To Slide Fence Forward or Backward
Refer to Figure 8:
1. Loosen the assembly locking handle (H).
2. Move the entire fence assembly (G) to the
desired position.
3. Tighten the assembly locking handle (H).
To Tilt Fence Backward
Refer to Figure 8:
The fence (A) can be tilted backward (E) up to
45°; that is, for a total included angle of 135° from
table surface.
1. Loosen the tilt locking handle (F).
2. Flip the stop plate (I) out of the way.
3. Tilt the fence (A) back (E) to the desired
angle, up to 135°. Or place a beveled
reference piece on the table and against the
fence, adjusting the fence until the fence
angle matches the bevel of gauge piece.
4. Tighten the tilt locking handle (F).
Important: When the tilted operation is finished
and the fence is returned to 90°, make sure to flip
the stop plate (I) back to its original position.

10.0 Adjustments

10.1 Fence Stop Adjustments

Refer to Figure 9:
Periodically check the 90° and 45° backward
(135°) tilt accuracy of the fence with an angle
measuring device, such as an adjustable square
or machinist's protractor.
90° Stop Fence Adjustment
The 90º stop is controlled by the stop bolt (C) and
the stop plate (D).
1. Set the infeed table (F, Fig. 7) to approx-
imately the same height as the outfeed table
(A, Fig. 7).
2. Move the fence (A) by releasing the
assembly locking handle (F) and pushing the
fence assembly (E) until it overlaps the
tables. Then, tighten the assembly locking
handle (F).
3. Adjust the fence (A) to a 90º angle by
releasing tilt locking handle (G), pulling the
fence upright, and tightening the tilt locking
handle.
Note: The stop bolt (C) should be resting against
the stop plate (D).
4. Place an angle measuring device on the table
and against the fence (A) to confirm a 90º
setting.
