Depth Adjustment With Fixed Base - Craftsman 320.27683 Operator's Manual

DEPTH ADJUSTMENT WITH FIXED BASE (Figs. 6 and 7)
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 sub-base.
The fixed base is designed with a
micrometer-fine adjustment system.
When the bit is lowered to the
approximate position desired (coarse
setting), the system can then be
micro-adjusted to the precise depth.
Coarse Adjustment:
Depressing the coarse adjustment
knob (B) allows you to quickly lower or
raise the cutter bit to an approximate
depth setting.
Fine Adjustments:
NOTE: Be sure that the worm gear
system is engaged before making fine
adjustments. Test it by turning the
Fine Adjustment Dial (C) clockwise
Fig. 6
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 Dial is marked in
1/64-inch increments. 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 inch.
The system allows a maximum of 7 full 360 ° revolutions clockwise, to lower the
cutter bit a total of 7/8 inch.
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
To Adjust Depth (Figs. 6 and 7)
Turn the motor off and unplug the
router from the power source.
Place the router on a flat, level
surface with the back of fixed base
facing you. Open the Motor Clamp
(A).
