9.3 Conveyor belt replacement

1. Disconnect sander from power.
2. Raise drum to highest position.
3. Loosen take-up screw nuts (Figure 11) on both
sides of conveyor to relieve belt tension, and
slide the driven roller fully inward.
4. Remove three (3) screws that attach conveyor
table to base. Lift up conveyor table and
remove it from machine. Avoid tearing the belt
on any edges underneath the conveyor bed. Do
not allow the Trackers to drop, as they may
break.

10.0 Abrasive dimensions

Use this diagram to cut after-market abrasive strips
to fit (or use a new Powermatic-supplied strip as a
template).

5. Install new belt along with trackers (see sect.
11.0), and re-install conveyor table. Tension
and track the new belt.
Note: If the conveyor belt continually tracks to one
side of the machine, reversing the belt on the
conveyor bed may remedy the problem. To make
sure the conveyor bed is not twisted, place a level
on the conveyor bed. Level the machine if needed.
If there is still a problem, proceed with the steps
below:
Step 1: Check conveyor drive roller and driven roller
to make sure they are parallel to surface of
conveyor bed. To do this, first center conveyor belt
on the bed. Then lay a straight-edge on the exposed
edge of conveyor bed on left (outboard) side,
extending it over the roller. Note distance between
roller and straightedge.
Step 2: Now repeat Step 1 on right (inboard) side of
conveyor. Compare the measurements from side to
side. If they are not equal, loosen one of the
brackets that hold the roller in place. Tip this
bracket until distance between roller and straight-
edge are equal from side to side, then tighten
bracket.
