Adjusting The Depth Of Cut - Flex FX4221 Operator's Manual

WARNING
performing any assembly or adjustments, or
changing accessories. Such preventive safety
measures reduce the risk of starting the tool
accidentally.

ADJUSTING THE DEPTH OF CUT

(FIG. 16 AND 17)
1. Select and install the desired cutter bit
following the instructions in the section
"INSTALLING AND REMOVING BITS".
2. Open the base lock lever.
3. Turn the depth adjustment ring until the bit
just touches the work piece. Turning the ring
clockwise raises the cutter bit (reduces the
cutting depth) while turning it counterclockwise
lowers the cutter bit (increases the cutting
depth).
4. Turn the depth adjustment scale clockwise until
the zero mark on the scale lines up with the
pointer on the depth adjustment ring (Fig. 16).
5. Turn the depth adjustment ring
counterclockwise until the pointer lines up
with desired depth of cut marking on the
depth adjustment scale (Fig. 17).
NOTE: Each mark on the depth adjustment
scale represents a depth change of 1/64"
(0.4 mm) and one full (360°) turn of the ring
changes the depth by 1/2" (12.7 mm).
6. Close the base lock lever.
NOTICE: Making a single deep cut is never
advisable. Smaller diameter cutter bits are
easily broken by too much lateral thrust and
torque. Larger cutter bits will cause a rough cut
and will be difficult to guide and control. For
these reasons, do not exceed 1/8" (3.2 mm)
cutting depth in a single pass.
Deep Cuts
Determining the proper cutting depth (for each
•
pass) should always be based on the material,
the size and type of cutter bit, and the power

of the motor.
Always make several progressively deeper
•
cuts. Start at one depth and then make several
passes, increasing the cutting depth each
time, until the desired depth is reached.
Making a cut that is too deep will put stress on
•
the motor and the cutter bit, and it may burn
the workpiece and dull the cutter bit. It could
also "grab" too much of the workpiece and
result in loss of control of the router, causing a
serious accident.
To be certain that the depth settings are
•
as desired, always make test cuts in scrap
material similar to the workpiece before
beginning the final cut.
Remember, knowing the right depth for each
•
cut comes with routing experience.
