Grizzly G9740 Planer User Manual


 
Extreme Duty Planers -15-
Table Rollers
The height of the table rollers will vary, depending
on the type of material you intend to plane. When
planing rough stock, you will need to set the roll-
ers
high to keep the lumber from dragging along
the table. Milled lumber should be planed with the
rollers set lower.
To adjust the table rollers correctly:
1. Loosen the lock on the adjustment lever
shown
in Figure 17. Pull the lever up to raise
the table rollers.

2. Determine the appropriate height for the type
of stock you are using.
The scale at the base of the adjustment lever
is numbered “0”, “1” and “2”. These numbers
represent how many millimeters the top
of the rollers are above the surface of the
table.
Since 1mm = .03937", figure that each notch
on the scale is approximately .004". The
ideal tolerance for the height of the table roll-
ers
is between .002"-.016".
Note—If
the table rollers are too high, snipe
or chipping may occur at the ends of the
workpiece. Only use the higher settings for
rough cut lumber. If you are unsure about
which height to use, experiment on scrap
lumber by using the trial and error method.
Always start at the smaller tolerances and
work up.
3. Pull the adjustment lever up to the appro-
priate
scale marks. Secure the adjustment
lever by tightening the lock.
