OPERATION MANUAL
The HAFCO WOODMASTER OS-140 Oscillating Spindle
Sander comes with a variety of table Inserts, each with
a different center hole diameter to be used with the
matching spindle size. (Fig.3.5)
NOTE
: ALWAYS use a table insert when sanding. Failure
to do so may cause serious injury to the operator or
damage to the machine.
There are two styles of table inserts supplied with the
machine.
One style has a round center hole for sanding with the
table in the 90° position. The second style insert has
an oval center hole for use when the table is tilted at
an angle for sanding. This oval hole protects the insert
from being damaged during the sanding operation.
To install an insert into the table, notice the cutout on
the edge of the insert. This aligns with the peg in the
recess on the table (Fig.3.6). Lower the insert into
position, making sure that the insert locates in the
recess and is flush with the table.
To remove a table insert, disconnect the machine from
the power supply and simply push it out of the table
with your finger from underneath.

3.8 INSTALLING THE TABLE INSERT
3.9 ALIGNING THE TABLE AT 90° TO THE SPINDLE
The table has the ability to tilt between 90° to 45°,
(0° to -45°). The table angle has been set in the factory,
but before the sander is used for the first time, squaring
the table to the spindle needs to be checked.
To align the table
1. DISCONNECT THE MACHINE FROM THE POWER
2. Loosen the table locking handle (Fig.3.7)
3. Rotate the geared handle on the opposite side of
the tilt mechanism and move the table into the
90-degree position. (Fig.3.8)
4. Lightly tighten the table in place so that any tilting
adjustments can be made.
