G1129 Feed Rates
The optimum feed rate for the power feeder will depend on the thickness of the material to be cut, the hardness of the workpiece, the speed of the cutting tool and number of teeth, tool shape etc. Generally, the following rules can be followed with a good level of success.
When selecting feed rates, remember these important tips:
•The thicker the material to be cut, the slower the feed rate.
•The harder the material, the slower the feed rate.
•The faster the cutter speed, the faster the feed rate.
•The greater the number of teeth or cutting sur- faces, the slower the feed rate.
G1129 speeds: 13, 26, 36, 72 FPM
There are two speed ranges on the motor (low and high) that are controlled by the switch.
To change the speed of the G1129:
1.Choose your speed range based on your material and cutter configuration. Using Figure 10, determine whether you need to switch the gears or just the switch setting.
Figure 10.
2.If you need to switch the gears, remove the gearbox cover by unscrewing the knurled knobs on the front of the power head.
3.Remove the hex nuts and washers which hold the drive gears in place. Figure 11.
4.Remove the gears and alternate their posi- tions. Slide them back onto their shafts.
5.Replace the hex nuts and attach the drive gear cover.
