G1129 Feed Rates - Grizzly G1128 Instruction Manual

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.

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.
