Lubricating Sleeve
Bearings
Lubricate the sleeve bearing with 30 WT oil every
10 hours of operation. No other lubrication is nec-
essary for this machine.
To lubricate the sleeve bearings:
1. Disconnect the machine from the power
source!
2. Remove the sanding belt.
3. Apply two or three drops of oil in the hole at
the end of the idler pulley (Figure 25).
Note—DO NOT apply extra oil. Too much oil can
cause the belt to slip.

Replacing Drive Belt
To replace and tension the drive belt:
1. Disconnect the machine from the power
source!
2. Remove the drive belt cover plate.
3. Loosen the three screws shown in Figure 23
and slide the drive belt housing down and
remove the old belt.
4. Place the new belt around the pulley wheels.
5. Put a screwdriver in the tension hole shown
in Figure 24 and pull up to tighten the drive
belt.
6. Tighten the drive belt housing screws while
keeping tension on the drive belt.
7. Test the belt tension by squeezing the belt
between your fingers. There should be no
more than
1
⁄4" of play in the belt.
Note—Too much tension in the drive belt will
cause increased noise and may overload the
motor, however, if the drive belt is too loose it
may slip and cause excessive wear on the belt.
