Carefully remove the machine from the carton.
MOVING CUTTINGHEAD TO THE UP POSITION 1. 2. Pull out the cuttinghead lockpin (A) Fig. 4, and move the cuttinghead (B) to the up position. Fig. 5 illustrates the lockpin (A) pulled out and the cuttinghead (B) in the up position. B A B A Fig. 4 Fig. 5 MOVING TABLE TO THE 0° CUT-OFF POSITION 1. 2. 3. Rotate locking knob (A) Fig. 6 counter-clockwise as far as it will go.
4. 5. 6. 7. 8. 9. Attach the fence slide support (E) Fig. 11 to the extension table (B) by using the two 5/16-18 x1-1/4” hex head screws, 5/16” lockwashers, and 5/16” flat washers (F). Insert the two screws up through the two holes (G) in the table extension and thread them into the two threaded holes (H) on the bottom of the fence slide support. NOTE: Leave the screws loose for now. Use a straight edge (C) Fig. 12 to align the fence slide support (E) with the saw fence (J), and tighten the two screws.
OPERATION OPERATING CONTROLS AND ADJUSTMENTS FASTENING MACHINE TO SUPPORTING SURFACE Before operating your miter saw, firmly mount it to a workbench or other supporting surface. Four holes (A) Fig. 18 are provided for fastening the saw to a supporting surface. When frequently moving the saw from place to place, mount the saw on a 3/4” piece of plywood. The saw can then be easily moved from place to place and the plywood can be clamped to the supporting surface using “C” clamps. A Fig.
B A D C E Fig. 21 B Fig. 22 ADJUSTING SLIDING FIT BETWEEN MOVABLE TABLE AND BASE DISCONNECT THE MACHINE FROM THE POWER SOURCE. To adjust the sliding fit between the movable table and the base, turn the nut (A) Fig. 23 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. A Fig.
TABLE HAZARD ZONE The area inside the two red lines (A) Fig. 26 on the table is designated as a HAZARD ZONE. Never place your hands inside this area while the tool is being operated. Always use a clamp to secure short workpieces. A Fig. 26 TILTING CUTTINGHEAD FOR BEVEL CUTTING DISCONNECT THE MACHINE FROM THE POWER SOURCE. IMPORTANT: Move the sliding fence to the left to provide clearance for the blade and guard. The degree of tilt determines how far to move the sliding fence.
ADJUSTING CHIP DEFLECTOR DISCONNECT THE MACHINE FROM THE POWER SOURCE. A A chip deflector (A) Fig. 31 is supplied to help prevent scrap or cut-off pieces from entering the upper blade guard. Adjust the chip deflector (A) so that it is almost touching the side of the blade. Loosen the screw (B), adjust the chip deflector (A), and tighten the screw (B). B Fig. 31 ADJUSTING 0° AND 45° BEVEL POSITIVE STOPS DISCONNECT THE MACHINE FROM THE POWER SOURCE. 1. 2. 3. 4. 5. 6. 7.
ADJUSTING SLIDING FIT BETWEEN TRUNNION AND BEVEL BRACKET After a long period of time, the sliding fit between the trunnion and the bevel bracket may need to be adjusted. Adjust the sliding fit by tightening the adjusting nut (C) Fig. 36, located underneath the bevel lock (A) Fig. 36 and collar (B) Fig. 36.This adjustment should not be so tight that it restricts the tilting movement of the trunnion when bevel cutting, or so loose that it affects the accuracy of the saw cut.
ADJUSTING THE DUAL LASERLOC™ LINES Each of the laser lines have been aligned parallel to the blade at the factory and should not need any adjustment prior to use. However, left-to-right adjustment to the laser lines may be necessary if you change to a thicker or thinner kerf blade. For information on changing your blade, refer to the "MAINTENANCE: CHANGING THE BLADE" section of this manual. To adjust the laser lines to the edge of the cut, follow the instructions below.
TO CHECK FOR VERTICAL ALIGNMENT Fig. G Fig. F 1. The vertical alignment is set correctly when the lines do not move horizontally (sideways) as the saw head is raised and lowered. If vertical alignment is correct, go to “TO SET LEFT AND RIGHT KERF ADJUSTMENT”. 2. To adjust, turn the left and right kerf adjustment screws one half turn clockwise. Take off the laser unit cover by removing the phillips screw on either side of the cover. (Fig. A). 3.
ADJUSTING LOWER BLADE GUARD After an extended period of use, the movable lower blade guard (A) Fig. 39 may not operate smoothly when the cuttinghead is lowered. You can correct this by adjusting the nut (B) until the lower blade guard (A) moves freely. A Do not over-tighten the nut as this can make the guard hard to move. B Fig. 39 TYPICAL OPERATIONS AND HELPFUL HINTS 1. 2. 3. 4. 5. 6.
CUTTING BOWED MATERIAL 1. If the material is bowed, position it on the table as shown in Fig. 43. 2. If the material is positioned the wrong way (Fig. 44), the workpiece will pinch the blade near the completion of the cut. CORRECT INCORRECT Fig. 43 Fig. 44 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° wall angle crown moulding. 1. Move the table to the 31.
45-45 CROWN MOULDING NOTE: If you are cutting crown moulding that is 45°-45°, follow the same procedure above, with the exception that the bevel position will always be at 30° and the miter position will be 35-1/4° to the right or left. OTHER ANGLES NOTE: The above instructions are assuming the angle between the walls is 90°. If you need help cutting crown moulding for walls set at angles other than 90°, see the instruction sheet “CUTTING CROWN MOULDING” on the Porter-Cable web site at www.portercable.com.
MAINTENANCE CHANGING THE BLADE Use only cross-cutting saw blades. DO NOT use blades with deep gullets as they can deflect and contact the guard DISCONNECT THE MACHINE FROM THE POWER SOURCE. NOTE: Use only 12" diameter blades with 1" arbor holes that are rated for 4000 RPM or higher. 1. Loosen the screw (A) Fig. 50 with the supplied wrench (B). 2. Rotate the arbor cover (C) Fig. 51, and lower the guard (D) Fig. 51 to the rear, exposing the arbor screw (E). 3. Remove the arbor screw (E) Fig.
KEEP TOOL CLEAN Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth. NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material. Wear ANSI Z87.1 safety glasses while using compressed air. FAILURE TO START Should your tool fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet. Also, check for blown fuses or open circuit breakers in the line.
