Porter-Cable 557 Instruction Manual page 13

To install alignment plate:
1. Align alignment plate (BB) with fence (see Fig. 22).
2. Slide alignment plate onto fence until it is seated (see Fig. 23).
NOTE: When alignment plate is installed, increase tool depth setting by 5/32"
(4.0 mm) (to allow for thickness of the alignment plate).
3. To remove alignment plate, lift lightly on the alignment plate and slide off fence.
"DOUBLE" BISCUITS
The alignment plate may also be used as a spacer to produce a groove that is wide
enough to accept two biscuits. After cutting a groove (or a group of grooves) in the
normal fashion, install the alignment plate and repeat the cuts. This will double the
width of each groove so that two biscuits can be installed in each groove.
DUST PORT (FIG. 24–25)
The tool is equipped with a dust port (CC) Fig. 24. A
large volume of sawdust and chips will be
exhausted from this port during tool operation. A
dust bag (DD) Fig. 25 and a dust/chip deflector
nozzle (C) Fig. 24 are furnished. A standard 1"
(25.4 mm) vacuum hose can be connected to the
dust port to facilitate dust collection.
Do not operate the tool without
a dust/chip deflector nozzle and dust bag, or a
vacuum hose, attached to the dust port.
DUST/CHIP DEFLECTOR NOZZLE
(FIG. 24)
The dust/chip deflector nozzle (C) pushes onto the dust port (CC) Fig. 24.
ATTACHING DUST BAG (FIG. 25)
Depress spring clips (EE) Fig.
(C). The bag is equipped with a zipper for ease emptying of the collected material.

"DUPLEX" HINGES (FIG. 26)
You can use the 557 to make the mortises required for installing "duplex" hinges.
Make a spacer and attach it to the 557 fence. The spacer can be made of scrap
3/4" (19 mm) wood. Cut the spacer to approximately 3-3/8" by 5-1/4" (85.7 mm by
133.4 mm) and attach it to the holes in the fence with two 3/4" (19 mm) wood screws.
#6 BISCUITS
With the 4" (101.6 mm) blade installed, set the depth adjusting turret to the MAX
position. Two cuts will be required to produce each groove for a #6 biscuit. Space the
centerlines of these two cuts 1/4" (6.4 mm) apart. When laying-out these cuts, mark
the first cut centerline, move over 1/4" (6.4 mm and mark the second cut centerline.
