OPERATION

ADJUSTING DEPTH OF CUT

Proper depth of cut depends on several factors: the peak horsepower of the router motor, the type of cutter, and the type of wood. A lightweight, low horsepower router is designed for making shallow cuts. A router with a high horsepower rating can safely cut deeper. Small cutters, such as veining bits with 1/16 in. (1.6 mm) cutting diameters, are designed to remove only small amounts of wood. Large cutters, such as straight-flute bits, are made to remove larger amounts of wood. You can make deeper cuts in soft woods, such as white pine, than in hardwoods, like oak or maple.

Based on these considerations, choose a depth of cut that will not place excessive strain on the router motor. If you find that extra force is needed or that the motor speed slows down considerably, turn off the router and

reduce the depth of cut. Then, make the cut in two or more passes.

When routing a groove that is too deep to safely cut in one pass, it is best to make the cut in several passes. We recommend that cuts be made at a depth not exceeding 1/8 in. (3.2 mm) and that several passes be made to reach deeper cuts.

Adjusting the depth of cut for the plunge router is different from adjusting the depth of cut for the fixed router.

TO ADJUST DEPTH OF CUT FOR FIXED ROUTERS See Figures 6 and 7.

Follow these steps to adjust depth of cut for fixed routers.

1. Unplug the router.

WARNING:

Failure to unplug the tool could result in accidental start- ing causing serious injury.

2.Place the router on a flat surface.

3.Loosen the locking arm.

4.Turn the depth adjusting ring counterclockwise until the tip of the cutter touches the flat surface.

5.Turn the depth indicator ring until the zero lines up with the indicator point on the base.

6.Position the router so that the cutter can extend below the subbase for desired depth of cut.

7.Turn the depth adjusting ring to obtain the desired depth of cut.

8.Tighten the locking arm securely.

NOTE: To adjust the depth of cut when the router is mounted to a router table, turn the depth adjustment ring until the cutter reaches the desired depth of cut.
