STEEL PLATEN ADJUSTMENT
The steel platen is located between the motor con-
tact wheel and the idler pulley. The surface of the
steel platen should protrude about 1/8"-1/4" past the
motor contact wheel and the idler pulley in order to
assure that the sanding belt will be in contact totally
with the steel platen.
Adjust as follows:
1. Remove sanding belt (refer to "Changing Sand-
ing Belt").
2. Loosen the two fixed screws (A), Figure 7, on
the steel platen at the rear of the machine.
FIGURE 7
3. Using a straight edge (B), to measure the pro-
truding distance between the surface of the steel
platen and the two pulleys (i.e. motor contact wheel
& idler pulley). See Figure 8.
4. Tap the steel platen with your hand until the pro-
truding distance is 1/8" to 1/4". The platen/motor
contact wheel & platen/idler pulley distances should
be the same.
5. Re-tighten the fixed screws (A) on the platen,
and replace sanding belt.
FIGURE 8
MOTOR/SANDING BELT ALIGNMENT
The motor and sanding belt on the edge sander were
factory aligned. However, if they are out of align-
ment due to shipping, adjust as follows:
1. Adjust front work table to its lowest position.
2. Loosen the two fixed screws on the dust chute
and remove chute from machine.
3. Remove safety guard.
4. Rotate the belt by hand to ensure that it is com-
pletely parallel with the steel platen, top left to top
right. Use a straight edge if necessary to measure
this.
5. If the sanding belt left to right is not parallel with
the steel platen, then the motor is not adjusted prop-
erly. Loosen the motor mounting screws (A), Figure
9, and adjust with the two jack screws (B).

6. If the right side of the sanding belt (near the
motor) is too high, adjust motor inclination inward,
until the sanding belt is parallel with the steel platen.
Then tighten the four motor fixed screws (E).
7. Rotate the sanding belt by hand again to make
sure it is completely parallel with steel platen.
8. Replace safety guard and dust hood, and ad-
just the sanding belt tracking if necessary.
