Unplug the router and make sure the switch is OFF before inserting or removing bit, making adjustments, or performing maintenance or service. DO NOT make adjustments while the router is running.
To adjust the bit depth:
1.UNPLUG THE ROUTER AND MAKE SURE THE SWITCH IS OFF!
2.Loosen the lock knob shown in Figure 4 and adjust the base to approximately the desired height.

3.Fine tune the depth of the router bit by using a measuring device, or place the router on the workpiece and eyeball the depth for an approximate measure- ment.
Note: The scale on the Model H7791 is not calibrated to any specific point. Only use it for reference when making incremental changes.
4.Tighten the lock knob to secure the base plate.
5.Plug in the router and make a test run in a scrap piece of wood to make sure the depth is correct.
Once the bit has been selected and installed properly, and the depth has been set, you need to determine the proper feed direction of the router across the workpiece:
To determine the feed direction:
1.Examine the top face of the workpiece and determine the direction of the grain. Feed the router so the bit is cutting with the grain (cutting along the growth rings as shown in Figure 5). Cutting against the grain chips the wood rather than cutting it, making a rougher surface with more “chip out.”

2.Always pass the router across the workpiece so the bit is rotating oppo- site the feed direction as shown in Figure 5. If the cutters are moving in the same direction you are feeding the router, you are performing a “climb cut.” This is a very dangerous opera- tion because the router could lunge forward out of your hands, causing serious personal injury.
