Belt Adjustment/Replacement; Table To Blade Alignment - Jet JPS2-115 Operating Instructions And Parts Manual

8.4 Table to blade alignment

Refer to Figures 8-9 and 8-10.
The table has been set square with the blade by
the manufacturer and no adjustment is necessary
now. As the saw receives extensive use, however,
table/blade squareness should be checked and
corrected if necessary. Use the miter slot to do this:
1. Disconnect machine from power source.
2. Raise blade to maximum height.
3. Mark one tooth (A) with a grease pencil and
position the tooth slightly above top edge of
table at the front.
Figure 8-9
4. Raise the miter gauge slightly out of its slot to
serve as a shoulder. Place a sliding square (B)
against side of miter bar, slide the scale over
until it touches the tip of blade, and lock the
scale in position. See Figure 8-9.
5. Rotate marked tooth (A) so that it is slightly
above table top at the rear and, using the
square as before, verify that the distance to
the blade is the same. See Figure 8-10. If the
distances are not the same, make a careful
note of the difference.

6. Slightly loosen the three mounting screws
(#10, sect. 14.2.1) that hold the table to the
stand; two in front, one in back.
7. Nudge table to bring miter slot in line with
blade.
8. Retighten mounting screws firmly.
9. Verify the alignment, angle pointer setting,
fence setting,
adjustments as needed.

8.5 Belt adjustment/replacement
