G0550/G0551 15" Planer -35-
Figure 39. Inspecting bed roller height.
The bed rollers ease stock movement through
the planer. The height of the bed rollers will vary
depending on the types of wood you will be plan-
ing. When planing rough stock, set the rollers
slightly high to keep the lumber from dragging
along the bed; however, snipe may be unavoid-
able. Smooth lumber should be planed with the
rollers set just above the plane of the table. This
will minimize snipe.
To adjust the bed rollers:
1. Ensure that power is disconnected and lay a
high quality straightedge across both table
rollers. Use a try square to keep the straight-
edge perpendicular to the table.
2. Use a feeler gauge to measure the clearance
between the bottom of the straight edge and
the table. Ideal clearance is between 0.006"
and 0.002". Measure in several places. This
measurement must be consistent across the
entire table. See Figure 39.
6. Repeat steps 1-5 for the opposite side of the
roller. Repeat all steps for the outfeed roller.
Feeler gauge measurement should be between
0.02"- 0.04"on the infeed and outfeed roller at
bottom dead center.
To adjust roller height:
1. Remove the drive chain cover to access the
roller adjustments on the drive chain side of
the planer. A single socket head cap screw
holds the drive chain cover on. The belt side
adjustments are already accessible.
2. Loosen the roller adjustment check nuts and
turn the roller height setscrews to change the
height of the roller as needed. See Figure
38.
3. Check the roller height according to the
above instructions. Continue turning the
setscrew until the roller is properly adjusted.
4. When the roller is set in the correct position,
retighten the check nuts you loosened in
step 2 above.
5. Check your settings one last time and repeat
steps 1-4 if necessary.
