ADJUSTING POSITION OF
SANDING ARM
DISCONNECT MACHINE FROM POWER
SOURCE.
The sanding arm can be positioned in the vertical or
horizontal position, or at any desired angle in between as
follows:
1. Loosen two bolts (A) Fig. 18, move the sanding arm
to the desired position, and tighten the two bolts.
THE SANDING ARM SHOULD NEVER
BE REPOSITIONED WHILE THE MACHINE IS
RUNNING.
2. When moving the sanding arm to the horizontal posi-
tion, the arm will contact the stop (B) as shown in Fig. 19.
BEFORE STARTING THE MACHINE
AFTER REPOSITIONING
ALWAYS CHECK THE TRACKING OF THE BELT.
ADJUSTING
DISC SANDER TABLE
The table is set at the factory so that the edge of the
table is approximately 3/32" away from the face of the
disc assembly. This is done to provide enough clearance
for the table when it is tiIted to 45 degrees. If it is ever
necessary to move the tabIe away from or closer to the
disc, loosen the four screws that hold the table to the
trunnions and move the table away from or closer to the
disc. If you cannot obtain enough movement of the table
with this method, proceed as follows:
DISCONNECT MACHINE FROM POWER
SOURCE.
1. Remove two screws, one of which is shown at (A) Fig.
20, and remove belt guard (B).
2. Remove hole plug (C) Fig. 21, and locate the two
screws that fasten the disc to the shaft.
3. Using wrench (F) Fig. 22, loosen the two screws on
hub of sanding disc and move the disc (D) in or out on
the shaft as needed.
4. Tighten two screws and replace hole plug and belt
guard.
NOTE: After this adjustment is made, make certain the
miter gage slot (E) Fig. 22 is parallel with the disc (D) by
following the instructions in "ADJUSTING MITER GAGE
SLOTS PARALLEL WITH THE BELT AND DISC."
