Belt Adjustment - Powermatic PM1000T Operating Instructions And Parts Manual

Refer to Figure 25.
1. Remove blade guard, pawl, table insert and
riving knife.
2. Use a 5mm hex key to loosen two socket head
button screws (E, Figure 25).
Note: These screws are accessible through
openings on the clamp plate (B) located
diagonally on either side of the lever (A). They
secure the bracket (C) to the riving knife carrier
plate.
Loosening these screws (E) will allow the
bracket (C) to slide back and forth on the
carrier plate.
3. Slide the bracket (C) toward or away from the
saw blade as required.
4. Tighten the socket head button screws (E).
5. Reinsert riving knife; tighten lock lever (A) and
check that saw blade/knife gap is between
3-8mm (Figure 26).
Note: Attempt to make the gaps as even as
possible.
9.7 Table to Blade Alignment
Refer to Figures 27 and 28.
The table has been squared to the blade by the
manufacturer and no adjustment should be needed
now. If cuts become inaccurate, check table/blade
squareness and correct if necessary. Use the miter
slot to do this:
1. Disconnect saw from power source.
2. Raise blade to maximum height.
3. Mark one tooth (A, Figure 27) with a grease
pencil and position the tooth slightly above top
edge of table at the front.
4. Raise miter gauge slightly out of its slot to
serve as a shoulder. Using a sliding square (B)
against the side of the bar, slide the scale over
until it touches the tip of the blade, and lock
scale in position.
Figure 27
5. Rotate marked tooth (A) so that it is slightly
above table top at the rear and, using the
square as before, verify that distance to blade
is the same. See Figure 28. If the distances
are not the same, make a careful note of the
difference.
6. Loosen table screws (item #66, section
15.1.1), and nudge table according to the
distance you noted.
7. Retighten screws firmly.
8. Verify alignment, angle pointer setting, fence
setting, etc. Make any needed adjustments.

9.8 Belt Adjustment

9.8.1 Belt Tension
Refer to Figure 29.
Tension of the drive belt should be inspected after
the first few days of operation, as it may stretch
slightly during initial use; also inspect it periodically
thereafter.
To tighten belt:
1. Disconnect machine from power source.
2. Loosen screw (C, Figure 29) with 8mm hex
key.
3. Press down on motor while retightening screw
(C).
If belt shows signs of wear, fraying, cracks, etc. it
should be replaced, as follows.
9.8.2 Belt Replacement
Refer to Figure 29.
1. Lower trunnion completely.
2. Loosen screw (C) with 17mm wrench.
3. Slightly loosen nut (D) with 1-1/4" (or
adjustable) wrench.
4. Pivot motor upward to release tension on belt.
5. Replace belt.
6. Push down on motor and tighten screw (C) to
tension new belt. Retighten nut (D).
