Table 6.2 Setting Mill/Drill Speeds (RPM)
Adjusting Belt Tension
To get maximum performance from your machine, keep the drive belts snug.
To adjust the tension on the mill belt, swing the roller to the front and place the belt on
the back of the roller. Loosen the nut at the bottom of the roller and slide the roller in its
shaft to the desired position. Tighten the nut (Figure 5.7).
When you use only the single long belt, the spring at the bottom of the idler-pulley brack-
et holds the idler pulley so it does not fall onto the motor pulley. To adjust the tension on
the spring, loosen the pivot shaft (Figure 6.11) and tighten or loosen the spring as need-
ed. Then retighten the shaft.
Figure 6.11 Adjust the spring tension on the idler-pulley bracket.
