Model H7790/H7791 Laminate Trim Router -10 -
Adjusting Bit Depth
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.
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.

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.
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.
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.”
