Operating Instructions

Bosch routers are designed for speed, accuracy and convenience in performing cabinet work, fluting, beading, cove-cutting, rounding edges, dovetailing, etc. They will enable you to accomplish inlay work, decorative edges and many types of special routing.

SETTING THE DEPTH OF CUT

Adjust the depth-of-cut only when the motor is switched off.

1.Install desired router bit.

2.Place the router on the workpiece.

3.Open the clamping lever. Fig. 11(A)

4.Turn the motor about 1/4” counter- clockwise so that the single triangle on the base lines up with “unlocked” symbol on the motor. Fig. 11(B) (Make sure that the indication the base is aligned with the line under the “unlocked” symbol on the motor. Otherwise, the router can be damaged.)

5.Slowly lower the motor until the router bit touches the workpiece. Fig. 11(C)

6.Note the reading on the scale (below the clamp lever) and add the desired depth-of- cut to this value to determine the target scale value.

7.Lower the motor until the target scale value is reached. Fig. 11(C)

8.Turn motor clockwise about 1/4” until single triangle lines up with “locked” symbol. Fig. 11(B)

9.Close the clamping lever. Always make sure the motor is held tightly in the base. Fig. 11(A) (The tension of the clamping lever can be changed by re-adjusting the nut.)

10.Check the depth-of-cut and make fine adjustment, if necessary. (Note: the depth of the motor and bit may shift very slightly when the clamping lever is close.)

11.Make a trial cut to verify that the router is set to make the cut as desired.

FINE DEPTH ADJUSTMENT

Adjust the depth-of-cut only when the motor is switched off.

1.Open the clamping lever. Fig. 11(A)

2.Adjust the desired depth-of-cut with the knurled wheel on back of base. Fig. 11(D)

3.Rotate the knurled wheel clockwise to

increase the routing depth, counterclockwise to decrease the cutting depth. Each complete rotation of the dial equals 1.25 mm (approximately 3/64").

4.Close the clamping lever. Fig. 11(A) Always make sure the motor is held tightly in the base. Re-adjusting the nut can change the tension of the clamping lever. (See “To Clamp Motor”, below)

5.Check the depth-of-cut and make an additional fine adjustment, if necessary. (Note: the depth of the motor and bit may shift very slightly when the clamping lever is closed.)

6.Make a trial cut to verify that the router is set to make the cut as desired.

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 8 mm wrench, rotate clamp nut clockwise SLIGHTLY (1/8 turn or less), then test clamp. Do not over-tighten.)

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.
