adjusting depth of cut

WARNING' Your router should NEVER BE TURNED ON or be connected
to the power source when you are assembling parts, making adjustments,
installing or removing collets / nuts, cutter bits, cleaning or when it is not
in use. Disconnecting the router will prevent accidental starting, which could
cause serious personal injury.
NOTE: All depth adjustments on the Fixed Base must be made with the
motor clamp open.
NOTE: For all Fixed Base Routers, the cutter bit depth equals the amount of the
cutter that is exposed below the surface of the subbase.
The fixed base is designed with a micrometer fine adjustment worm gear system.
When the bit is lowered to the approximate position desired (coarse setting), the system
then can be micro adjusted to the precise depth.
Coarse Adjustment:
Depressing the Coarse Adjustment Knob (B) ailows you to quickly lower or raise the
cutler bit to a larger or approximate depth setting.
Micro Adjustments:
NOTE: Be sure the worm gear system Is engaged before making fine
adjustments. Test it by turning the Fine Adjustment Dial (C) clockwise and
counter-clockwise to see if the bit lowers and raises. If it does not, press in
the Coarse Adjustment Knob and turn the Fine Adjustment Dial until the gears
engage, then reset zero “0” on Depth Indicator Ring (D).
The Depth Indicator Ring (D) located on the Fine Adjustment Diai is marked incremenfally
in 64's. Turning the fine adjustment dial clockwise 180° (1/2 turn), lowers the cutter bit
1/16-inch. One full turn clockwise (360°) zero ”0" to zero “0” lowers the bit 1/8-in„
The incremental lines between the 64th marks are 1/128's for super fine micro adjustments.
The system allows a maximum of 7 full 360° revolutions, clockwise, to lower the cutter
bit 7/8-in.
The Depth Indicator Ring may be reset to zero “0” without moving the fine adjustment dial.
This allows the user to begin adjustments from any reference point desired.
