Porter-Cable 892, 8931, 891 instruction manual Installing the Motor, Adjusting Depth of CUT

INSTALLING THE MOTOR

Disconnect tool from power source.

1.Open the clamp (A) Fig. 1 and set the power unit in the base unit.

2.Align the rack and pin (C) Fig. 1 of the power unit with the grooves in the base, pull the lever (B) Fig. 1, and lower the motor into the base.

3.Close the clamp (A).

4.Reverse the procedure to remove.

ADJUSTING DEPTH OF CUT

Disconnect tool from power source.

1.Open the clamp (A) Fig. 6.

2.Pull lever (B) and set router on work so bit just touches it and the router is flat and level.

3.While holding the lever (B), turn depth knob (C) until zero lines up with zero mark on router base.

NOTE: Setting the index line to 1/16" on the knob means the cutting edge of the bit is exposed 1/16" below the base.

ADJUSTING SUB-BASE ALIGNMENT (All Routers)

Applications using a templet guide require the bit to be centered in the guide. This, in turn, requires the center hole in the sub-base to be in line with the collet of the motor unit. Your model has an adjustable sub-base which has been aligned at the factory. The fixed-base router comes with the large hole (Fig. 7). To use templet guides, use an accessory base, and/or, if the sub-base has been removed and readjustment is required, use the following procedure.

Disconnect tool from power source.

1.Loosen the sub-base mounting screws (C) Fig. 7 just enough to allow the sub-base (D) to move.

2.Open the clamp (A) Fig. 7, and adjust the power unit so that the collet nut (B) engages the center hole in the sub-base (D). Allow the sub-base to center itself on the collet nut. Close the clamp (A).

3.Tighten the sub-base mounting screws (C) Fig. 7 securely.
