G7211/7212 24" Bandsaw -17-
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
9
⁄16" 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
3
⁄4" 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.
5. Move the V-belt to the pair of pulleys which
provide the desired speed.
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.
