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 14" 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.

Lubricating Sleeve

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.
