Bosch Router PR20EVS

Warning: Ensure the router is unplugged before starting the adjustment process.

Loosen the screw using a Phillips screwdriver.

Rotate the knurled knob on the back of the guide to adjust the roller/bushing.

Enter the distance between the bit and the top of the roller/bushing guide.

Tighten the clamping screw using a Phillips screwdriver.

Make a trial cut to check the setting.

Sign off on the adjustment of roller/bushing guide.

Warning: Cutter diameter must be at least 1/4” smaller than opening for the bit and cutter.

Is the bit and its cutter centered in the subbase opening?

If not, follow the steps below to adjust the location of the subbase.

Loosen the four screws that hold the subbase.

Adjust the location of the subbase as needed so that the bit and its cutter are centered in the subbase opening.

Tighten the four screws that hold the subbase.

Note: This subbase is not designed for use with templet guides. See optional PR009 and PR010 Accessories for use of templet guides with the palm router.

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

Open the clamping lever. Fig. 12(A)

Adjust the desired depth-of-cut with the knurled wheel on back of base. Fig. 12(D)

Each complete rotation of the dial equals 1.25 mm (approximately 3/64\)"

Close the clamping lever. Fig. 12(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)

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.)

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

Insert bit to the desired depth as per the instructions on page 9.

Press large red spindle lock button on top of offset spindle (Fig. 27).

Tighten collet nut using the same collet wrench as is used on the motor’s own collet nut. (The collet used on the PR004 is the same type of self-releasing collet used on the motor itself when used with the other bases.)

Make a trial cut to check the depth and readjust as necessary.

Lay the router or motor on its side (unless router is in the plunge-base router configuration). The router can also be stood on its head for bit changes, such as when in the plunge-base configuration.

Press spindle lock to prevent rotation of collet chuck. NOTE: it may be necessary to rotate collet nut to engage spindle lock.

Next, use the collet wrench to loosen the collet chuck assembly in a counter-clockwise direction (viewed from bottom of router).

Insert the shank of the router bit into the collet chuck assembly as far as it will go, then back the shank out until the cutters are approximately 1/8 to 1/4 away from the collet nut face.

With the router bit inserted and the spindle lock engaged, use the collet wrench to firmly tighten the collet chuck assembly in a clockwise direction (viewed from bottom of router).

To ensure proper gripping of the router bit and minimize run-out, the shank of the router bit must be inserted at least 5/8.

Warning: Cutter diameter must be at least 1/4” smaller than opening for the bit and cutter.

Caution: To prevent damage to tool, do not tighten collet without a bit in place.
