4-1. Selling Point Descriptions

(1) Tool-less 2-stage motor release clamp for quick and accurate depth adjustments
The Models M 12VC, M 12SC, KM 12VC and KM 12SC are provided with the lever that has the 2-stage
locking mechanism to secure the housing temporarily.
For the conventional routers, there was a fear that the housing might slide down by its own weight when
adjusting the cutting depth while the lever was in the released position (Fig. 1) or the cutting depth might be
changed when shifting the lever from the released position to the secured position (Fig. 3). Because the new
lever of the Models M 12VC, M 12SC, KM 12VC and KM 12SC can lightly secure the housing at the
temporarily secured position (Fig. 2), the housing does not slide down by its own weight and the cutting depth
is not changed when shifting the lever to the secured position. In addition, the cutting depth is finely
adjustable thanks to the temporary securing function. How to use the 2-stage lock lever is exemplified below.
Released position (Fig. 1)
1
Shift the lever to the fully opened position in order to
move the housing widely for rough cutting depth
adjustment, bit replacement or changing to the plunge
base.
Temporarily secured position (Fig. 2)
2
Shift the lever until you feel a click at the center position
between the secured position and the released position.
The cutting depth is finely adjustable at this position as
the housing does not slide down by its own weight.
Fixed position (Fig. 3)
3
Shift the lever to the secured position after fine
adjustment of the cutting depth at the temporarily
secured position.
Note:
The motor housing can be temporarily secured by clamping the
lever (the motor housing does not slide down by its own weight).
If the motor housing slides down, make adjustments by tightening
the knob nut. Turning the knob nut clockwise tightens the lever,
while turning the knob nut counterclockwise loosens the lever.
