NOTICE: When making depth adjustments on the plunge base, the motor clamp
should always be closed securely.
Using the Depth-Stop Turret to Set Up Deep Cuts (Fig. 10)
NOTICE: Making a single deep cut is never advisable. Smaller diameter cutting
bits are easily broken by too much side thrust and torque. Larger cutting bits
will cause a rough cut and be difficult to
guide and control. For these reasons, do not
exceed 1/8 in. depth of cut in a single pass.
To produce deep cuts, always make several
progressively deeper cuts by starting with the
highest step on the depth-stop turret, and,
after each cut, rotate the turret to the next
lower step until the lowest step is reached.
Each of the steps progresses by 1/8-inch
increments. The 5 steps represent a total of
3/8 inch to 7/8-inch-. with a full 360 ° rotation
of the turret. Repeat this process if necessary.
Micro-adjustments with the Depth-Stop
Rod and Depth-Stop Turret
The depth-stop rod has a micro adjustment
knob (A) that turns a screw (B) (inside the rod)
either clockwise or counterclockwise to lower
or raise the depth-stop rod on the turret (C)
for micro-fine adjustments of the plunge depth.
Each complete revolution of the Micro-adjustment knob adjusts the plunging
depth by approximately 1/32 inch.
A reference indicator line is embossed into the depth-stop rod under the fine-
adjustment knob to set a reference point of "0".
When micro-adjusting the plunge depth, always make sure that the micro-
adjustment knob has been turned down (clockwise) several revolutions from the
top before setting the depth-stop rod and depth-stop turret.
Always set your micro-adjustments with the plunge action locked in the raised,
(or up) position.
To use the micro-adjustment knob after the depth rod and turret have been set,
check the final depth setting and micro-adjust as follows:
• To micro-increase the plunge depth, raise the micro-adjustment screw by
turning the knob counterclockwise the desired amount.
To micro-reduce the plunge depth, lower the micro-adjustment screw by
turning the knob clockwise the desired amount.
