Limit Switches
The Model SB1020 is equipped with limit switches that prevent the saw from operating if the blade is not properly tensioned and stop the saw motor when it reaches the end of a cut. If either of these functions does not operate correctly, you will need to adjust the appropriate limit switch.
To adjust the blade tension switch:
1.DISCONNECT BANDSAW FROM POWER!
2.Tension the blade until the tension gauge reads 20,000 PSI, which is the transition from yellow to green.
3.Use a 3mm hex wrench to loosen the two button head cap screws that secure the blade tension switch bracket shown in Figure 46.
