Setting Feed Rate; Adjusting/Replacing Knives (G0890) - Grizzly G0890 Owner's Manual

Setting Feed Rate

High Feed Rate .......................................28 FPM
Low Feed Rate ........................................16 FPM
The infeed and outfeed rollers move the work-
piece through the planer while keeping it flat and
providing a consistent rate of movement. The
speed that these rollers move the workpiece
through the planer is the feed rate.
Generally, low feed rates are used for dimension-
ing passes, while higher feed rates are used for
finishing passes.
The figure below illustrates the three different
positions of the feed rate control knob:
• Push knob in to use high feed rate.
• Pull the knob out to use the low feed rate.
• Move knob to center position to place gear-
box in neutral.
Figure 18. Feed rate control knob positions.
NOTICE
Only change the feed rate when the planer
is running, but DO NOT attempt to change
the feed rate during any cutting operations
or damage to the gearbox will result.
