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.

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.

Remove collet from motor and install toothed drive pulley using collet wrench. Make sure that drive gear is fully tightened onto the motor’s spindle.

The motor is then installed into the base according to the instructions on page 9.

Insert screwdriver (not included) through the U-shaped opening in the subbase to fit belt over drive pulley.

Warning: To avoid accidents always disconnect the tool from the power supply before cleaning or performing any maintenance.

The tool may be cleaned most effectively with compressed dry air. Always wear safety goggles when cleaning tools with compressed air.

Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through openings.

Caution: Certain cleaning agents and solvents damage plastic parts. Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.

Is the tool disconnected from the power supply?

Ventilation openings and switch levers clean and free of foreign matter?

No pointed objects used for cleaning?

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