FOREWORD
Your Porter-Cable Trim Saw is designed for cutting trim, composition board,
plywood, plastics, plexiglas, and other problem materials. Maximum depth of
cut is 1-5/16" at 90° and 1-1/16" at 45° with 4-1/2" diameter blade.
A Combination Blade is furnished with your saw and is an excellent blade for
all general ripping and crosscutting operations. When crosscutting and
smoothness of cut is an important factor, a thin rim blade is recommended.
Also, a fine tooth blade should be used when cutting plywood and masonite.
Special blades are available for cutting plexiglas and "problem materials"
such as metal laminates and gauge size sheet steel.
TO CHANGE SAW BLADES
CAUTION: DISCONNECT SAW FROM POWER SOURCE.
To remove the blade, place the teeth of the blade against the edge of a board
and loosen the blade retaining screw by turning it counterclockwise with
wrench provided. Remove blade retaining screw and outer flange washer.
Hold telescoping guard open and remove blade. Before installing a new
blade, remove inner flange washer and wipe it clean. Also remove any
sawdust that may have accumulated within the guards, around the saw
arbor, and from the telescoping guard spring. Check the telescoping guard
to insure it is in working order.
CAUTION: If telescoping guard movement is sluggish or binding
exists, return the saw to your nearest AUTHORIZED PORTER-CABLE
SERVICE STATION or PORTER-CABLE SERVICE CENTER for repair.
NEVER use your saw if the telescoping guard is not in working order.
Install the inner flange washer and place the new blade on the arbor making
sure the teeth point UP at the front of the saw (EXCEPT for the special blade
for cutting plexiglas – see below).
Clean and replace the outer flange washer making certain the square hole
mates with the squared end of the saw arbor. Install and firmly tighten the
blade retaining screw.
INSTALLING PLEXIGLAS BLADE
For cutting plexiglas only, the special blade is installed with the teeth pointing
DOWN at the front of the saw.
TO ADJUST DEPTH OF CUT
CAUTION: DISCONNECT SAW FROM POWER SOURCE.
Loosen depth adjusting knob (A) Fig. 1, and raise or lower saw housing until
the blade extends the desired distance below the base. For best results the
blade should just protrude through the material being cut. Firmly tighten knob
to hold saw in selected position.
