Router including cutting depth locking and adjustment mechanism

A router comprising:

• a motor unit;
• a base that receives the motor unit;
• a threaded shaft rotatably supported on the motor unit;
• a slide supported on the base, the slide engaging with the shaft in a first position of the slide in which micro-adjustments to a cutting depth are permitted in response to rotation of the shaft relative to the base and disengaging with the shaft in a second position of the slide in which macro-adjustments to the cutting depth are permitted in response to an external force from a user to translate the motor unit relative to the base;
• and
• a lever movable between
• a locked position in which neither macro-adjustments nor micro-adjustments are permitted regardless of the slide being in the first position or the second position,
• a micro-adjustment position in which only micro-adjustments are permitted with the slide in the first position, and
• an unlocked position in which the lever disengages the slide from the shaft to permit macro-adjustments.

A method of adjusting a cutting depth of a router, the router including a motor unit and a base that receives the motor unit, the method comprising:

• biasing a slide on one of the base or the motor unit to a first position engaging a threaded shaft on the other of the base and the motor unit, preventing macro-adjustments of the cutting depth;
• moving a lever from a locked position, in which neither macro-adjustments nor micro-adjustments to the cutting depth are permitted regardless of the slide being in the first position or a second position in which the slide is disengaged from the shaft, to a micro-adjustment position in which only micro-adjustments to the cutting depth are permitted with the slide in the first position;
• moving the lever from the micro-adjustment position to an unlocked position;
• and
• in response to the lever moving into the unlocked position, moving the slide from the first position to the second position, thereby disengaging the slide from the shaft to permit macro-adjustments of the cutting depth.
