COARSE DEPTH ADJUSTMENT
This system allows you to quickly make large
changes in plunge depth or bit height.
1. To unlock the coarse adjustment knob, move
the coarse adjustment lock to the left.
(counter-clockwise).
2. Rotate the coarse adjustment knob clockwise
to lower the depth rod, producing a shallower
cut. Rotate the coarse adjustment knob
counter-clockwise to raise the depth rod,
producing a deeper cut (Fig. 8).
3. To lock the depth rod at desired setting,
simply turn the coarse adjustment lock to the
right and press down firmly.
COARSE ADJUSTMENT INDICATOR
The coarse adjustment indicator can be moved
independently of the coarse adjustment knob.
This allows the indicator to be zeroed at any
given depth. After zeroing, when the knob is
rotated, the indicator rotates with it, indicating
the change in the depth of cut in fractions of an
inch. Increasing numbers indicate deeper cut.
(An optional metric coarse adjustment indicator
is available separately.)
FINE ADJUSTMENT KNOB
The fine adjustment knob allows extremely
precise adjustment of the bit depth. One
complete revolution
approximately 5/64". It should be adjusted only
after the coarse adjustment lock is locked.
Rotating the fine adjustment knob counter-
clockwise causes the depth rod to move up,
producing a shallower cut. Rotating the fine
adjustment knob clockwise causes the depth
rod to move down, producing a deeper cut
(Fig. 9).
FINE ADJUSTMENT INDICATOR
The fine adjustment indicator can be moved
independently of the fine adjustment knob.
This allows the indicator ring to be zeroed at
any given depth. After zeroing, when the knob
is rotated, the indicator turns with it, indicating
the fine change in the depth of cut (in mm or
fractions of an inch). Fine depth adjustment in
increments as small as 0.1 mm (.004") is
possible (Fig. 9).
