Adjusting Bed Rollers

You can adjust the height of the bed rollers according
to the material being planed. As a general rule keep the
roller height within 0.002"– 0.020" (.050 –.5mm) above
the table (Figure 17). When planning rough stock, set
the rollers high to keep the lumber from dragging along
the bed. When planning milled lumber, set the rollers
low to help minimize snipe.

Misaligned bed rollers can be the root of many planing
problems, so care must be taken to achieve precise
results side to side along the roller length. To ensure
accurate results and make the adjustment process
quicker and easier, a dial indicator is recommended.
However; if not available, a straightedge and feeler
gauges can be used.

Adjusting the bed rollers:
1 Ensure machine is switch off and unplugged from

power source.

2 Lower the table to it’s maximum opening to give

yourself working room below the cutter head.

3 Loosen the 4 set screws (Figure 15-A & 15-B)

above the roller adjusters.

4 Rotate the adjusters to raise or lower the rollers to

reach your desired height.

5 Verify both sides of the bed roller are at the same

height, and lock them in position with the set screws.

6 Double check the roller heights to make sure they did

not change when you locked them (if they changed,
repeat the procedure). Height must be equal.
