COARSE ADJUSTMENT: To make a large depth adjustment, depress coarse adjustment release lever and raise or lower to desired depth. There are three notches in the motor housing which are spaced 1/2" to facilitate this adjustment. 4. FINE DEPTH ADJUSTMENT: To use the fine adjustment feature, turn the fine adjustment knob clockwise to lower the router bit or counter-clockwise to raise it. NOTE: Be sure coarse adjustment lever is engaged in one of the coarse adjustment notches before making a fine adjustment. To allow precise settings, the indicator ring is graduated in English and Metric increments. (Note: one full turn of fine adjustment knob = 1/16" or approximately 1.5 mm. The fine adjustment mechanism has a total adjustment range of 7/8" (23 mm). Each cast indicator mark next to coarse adjustment lever is equal to 1/8" To prevent damage to tool, avoid wedging the coarse adjustment lever against the upper A or lower B portion of the housing as shown in figure 10. 5. After making depth adjustments, re-clamp the motor. The indicator ring may be reset to zero without moving the fine adjustment knob, to allow the user to begin the adjustment from any reference point desired. When the router is installed in a router table, it can be adjusted with a 1/8" hex wrench, not included with all models. (See page 21). The RA1002 Fine Adjustment Control Extension, an optional accessory for the non- plunge bases, allows fine adjustment from beyond the top of the motor housing. To install, simply press the RA1002 into the end of the base's own fine adjustment knob. (Fig. 11) TO CLAMP MOTOR When final coarse and fine adjustments have been made, fasten the base clamp lever to secure adjustments. (If additional clamping force is desired: using a 10 mm wrench, rotate clamp nut clockwise SLIGHTLY (1/8 turn or less), then test clamp. Do not overtighten.) DEEP CUTS For deeper cuts, make several progressively deeper cuts by starting at one depth and then make several subsequent passes, increasing the cutting depth with each pass. To be certain that your depth settings are as desired, you may want to make test cuts in scrap material before beginning work. FIG. 11 DEPTH ADJUSTMENT WITH PLUNGE BASE PLUNGING ACTION The plunge feature simplifies depth adjustments and will allow the cutting bit to easily and accurately enter the workpiece. To lower, push plunge lock lever to the left, apply downward pressure until you reach desired depth, and release pressure on lever to lock (Fig. 12). The plunge lock lever is spring loaded and returns automatically to the locked position. To raise the router, push plunge lock lever to the left, release pressure on router and the router will automatically retract the bit from the workpiece. It is advisable to retract the bit whenever it is not engaged in workpiece. -13- FIG. 12
