IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS READ AND FOLLOW ALL INSTRUCTIONS. This tool was designed for certain applications.DO NOT modify or use it for any application other than for which it was designed, if you have any questions relative to its application do not use the tool until you have written Porter-Cable and we have advised you.
25. WARNING: SOME DUSTCREATED BYPOWER SANDING, SAWING, GRINDING, DRILLING, ANDOTHER CONSTRUCTION ACTIVITIES contains chemicals knownto causecancer, birthdefectsor otherreproductive harm. Some examples of these chemicals are: • lead from lead-based paints, • crystalline silica from bricks and cement and other masonry products, and • arsenic and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work.
REPLACEMENT When servicing, PARTS use only identical replacement parts. POLARIZED PLUGS: To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the ether). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way. MOTOR Many Porter-Cable tools will operate on either D.C.
UNPACKING 1. Carefully remove the machine from the car_on. Retain all packing materials until you have inspected and satisfactorily operated the machine. WARNING: Do not connect the machine to the power source until you have read and understood this entire instruction manual, 2. Place the machine on a firm, level surface with extra room for handling and proper support of the workpiece. 3. Familiarize yourself with all features and controls as explained in this manual. Fig.2 4 / 4.
MOVING TABLE TO THE 0 DEGREE CUT-OFF POSITION 1. Rotate locking knob (A) Fig. 6, counter-clockwise as far as it will go to unlock. Depress lever (B) and rotate table (C) to the 0 degree straight cut-off position, release lever (B) and tighten locking knob (A). 2. Fig. 7, illustrates the table (C) in the 0 degree straight cut-off position. 3.
D C Fig. 7C Fig.7D 3. Use a straight edge (C) Fig. 7C, to make the extens on table (B) even with saw table (D), and tighten the two screws (A) Fig.TB. 4. Attachthe fence slide support{E).,Fi9.7D, to the extension table (B) by using the two 1 1/4" long hex head screws, _/]6 Iockwashers and 5/lb Tlat washers (F). Bringscrews up through the two holes ({3) in table extension and thread them into the two threaded holes (H) onbottom of fence slide support. NOTE: Do not completely tighten screws at this time.
9. Position lock handle (M) Fig. 7J, on stud and replace screw and spring (L) that were removed in STEP 7. NOTE: Lock handle (M) is spring-loaded and can be repositioned by lifting up on handle. Fig. 7J ATTACHING DUST BAG Depress spring clips (A) Fig. 8, of dust bag (B) and clip dust bag (B) onto end of dust chute. FASTENING MACHINE TO SUPPORTING SURFACE Fig. 8 Before operating your compound miter saw, firmly mount it to a workbench or other supporting surface. Four holes, (A) Fig.
DANGER: A TURNING SAW BLADE CAN BE DANGEROUS. AFTER COMPLETING CUT, RELEASE SWITCH TRIGGER (A) FIG. 12, TO ACTIVATE BLADE BRAKE. KEEP cu'n'INGHEAD DOWN UNTIL BLADE HAS COME TO A COMPLETE STOP, WARNING: THE TORQUE DEVELOPED DURING BRAKING MAY LOOSEN THE ARBOR SCREW. THE ARBOR SCREW SHOULD BE CHECKED PERIODICALLY AND TIGHTENED IF NECESSARY. LOCKING SWITCH IN THE "OFF" POSITION IMPORTANT: When the miter saw is not in use, the switch should be locked in the OFF position using a padlock (B) Fig.
A To adjust the sliding fit between the movable table and the base, turn nut (A) Fig. 14, clockwise to increase the sliding fit (opposite to decrease the fit). This adjustment should not be so tight that it restricts the rotating movement of the table, or so loose that it affects the accuracy of the saw. Fig. 14 ADJUSTING FENCE 90 DEGREES TO BLADE IMPORTANT: BEFORE MAKING THIS ADJUSTMENT, SET THE BLADE AT 0 DEGREES TO THE TABLE. SEE SECTION "ADJUSTING 0 AND 45 DEGREE BEVEL POSITIVE STOPS." 1.
A C B Fig. 18 ATTACHING OPTIONAL Fig. 19 WORK CLAMP The work clamp is an important accessory. After purchase, the work clamp can be attached to any one of the four holes (A) Fig. 18, provided on the base of the machine, (three of which are shown). 1. Thread lock knob (B) Fig. 19, into threaded hole where the clamp will be inserted. Place post (C) of work clamp down through hole as far as possible. Tighten lock knob (B).
1. The cuttinghead of your compound miter saw can be tilted to cut any bevel angle from a 90 degree straight cut-off to a 45 degree left bevel angle by loosening bevel lock handle (A) Fig. 23, tilting cuttinghead (B) to the desired angle, and tightening lock handle (A). 2. Positive stops are provided to rapidly position the saw blade at 90 and 45 degrees to the table.
Fig, 27 Fig. 28 ADJUSTING 0 AND 45 DEGREE BEVEL POSITIVE STOPS 1. DISCONNECT SOURCE. THE SAW FROM THE POWER 2. Adjust saw so that both bevel and miter pointers are set at 0 degrees. Tighten bevel lock handle and lock cuttinghead in down position. 3. Place one end of a square (A) Fig. 27 on the table and the other end against the blade. The blade should be set at 90 degrees to the table. 4. If an adjustment is necessary, loosen bevel lock handle (H) Fig. 28.
Correct adjustment provides for a good snug sliding fit between these two parts. This adjustment should not be so tight that it restricts the tilting movement of the trunnion (A) when bevel cutting, or so loose that it affects the accuracy of the saw cut. ADJUSTING THE TENSION OF cu'n'INGHEAD RETURN SPRING The tension of the cuttinghead return spdng has been adjusted at the factory in order that the cuttinghead returns to the up position after a cut has been made.
TYPICAL OPERATIONS AND HELPFUL HINTS 1. Before cutting, make certain the cutting arm and table area are at their correct settings and firmly locked in place. 2. Before cutting, determine right size for the saw. 3. Place the workpiece on the table and hold or clamp it firmly against the fence. Fig. 35 illustrates the optional work clamp (A) being used to clamp a workpiece to the fence and table. 4.
CUTTING BOWED MATERIAL 1 ----7 RIGHT WRONG Fig.39 Fig. 40 I. When cutting fiat pieces, first check to see if the material is bowed. If it is, make sure the material is positioned on the table as shown in Fig. 39. 2. If the material is positioned completion of the cut. CONSTRUCTING the wrong way, as shown in Fig. 40, the workpiece WORK SUPPORT will pinch the blade near the EXTENSIONS C A B Fig. 41 One of the unique features of the miter saw is the ease of constructing work supporLs. Fig.
CUTTING CROWN MOULDING One of the many features of the saw is the ease of cutting crown moulding. The following is an example of cutting both inside and outside corners on 52/38 degree wall angle crown moulding. E A NOTE: The following procedure for inside or outside crown molding corners is the same with the exception that the bevel position will always be at 30 degrees and the miter position will be 35-1/4 degrees to the right or left. 1.
MAINTENANCE CHANGING THE BLADE Fig. 46 Fig, 47 WARNING: USE ONLY CROSS-CUTTING SAW BLADES. DO NOT USE BLADES WITH DEEP GULLETS AS THEY CAN DEFLECT AND CONTACT GUARD 1. Use only 12" diameter blades with 1" arbor holes that are rated for 4200 RPM or higher. 2. DISCONNECT 3. Loosen screw (A) Fig. 46, with wrench 4. Rotate arbor cover (C) Fig. 47, and lower guard (D) Fig. 47, to the rear, exposing arbor screw (E). MACHINE FROM THE POWER SOURCE. (B) (provided). 5. Remove arbor screw (E) Fig.
BRUSH INSPECTION AND REPLACEMENT C B Fig. 49 CAUTION: BEFORE INSPECTING Fig. 50 BRUSHES, DISCONNECT THE MACHINE FROM THE POWER SOURCE, Brush life varies, depends on the load on the motor. Check the brushes after the first 50 hours of use of a new machine, or after a new set of brushes has been installed. After the first check, examine them after about 10 hours of use, until replacement is necessary. The brush holders (A) Fig. 49, are located on the motor housing opposite each other. Fig.
