Changing Speeds
The G7211/G7212 24" Bandsaw provides two speeds, 2800 and 3500 FPM, to make cutting easier. In many applications, blade speed is a matter of personal preference. Usually the higher speed will produce the best results, but if the motor is straining while cutting, try a slower blade speed. Blade speed is also affected by the type of wood, denser woods need a different speed than a softer, lighter wood. Ultimately blade speed is a matter of trial and error. Whenever possible test the cut on a scrap piece first to gauge how well the blade is cutting at the selected speed.
To change bandsaw speeds:
1. Turn the bandsaw power switch off and dis- connect from power source.
2.Use a 9Ú16" open end wrench to loosen the lock nut and lock bolt on the lock system. See Figure 11. This provides room to turn the adjuster nut.
3.Use a 3Ú4" box wrench to loosen the adjuster nut. Loosen as needed to allow the shaft to move. See Figure 12.
4.Select the pulleys for the speed desired. The rear or smaller motor pulley provides the slower, 2800 FPM, speed, while the front pulleys are for the faster 3500 FPM speed.
See Figure 13.

6. Tighten the belt by sliding the adjuster nut and shaft up or down as needed.
7. Tighten the adjuster nut.
8.Bring the lock bolt head snug against the adjuster nut. Tighten the lock nut.
