POWER CONNECTIONS Your new Compound Miter Saw is DOUBLE-INSULATED to give you added safety. As a result, this saw is equipped with a two-prong plug which permits you to use any conventional 120 volt electrical outlet with concern for maintaining a ground connection. Before connecting the motor to the power source, confirm that the electric current is 120 volts, and that all connections are making good contact. NOTE: Running the saw on low voltage will damage the motor.
FUNCTIONAL DESCRIPTION FOREWORD Delta Model 36-312 is a high capacity 12" single-bevel compound miter saw designed to cut wood and non-ferrous metals. This machine is supplied with new design features that increase the cutting capacity. This machine can cut 6" base moulding mounted vertically, crosscut 2" x 8" dimensional lumber, miter 2" x 6" dimensional lumber at 45° both left and right, and bevel 2" x 8" dimensional lumber left at 45°. It has positive miter stops at 0°, 15°, 22.5°, 31.
MOVING TABLE TO THE 0° CUT-OFF POSITION 1. 2. Rotate the locking knob (A) Fig. 5 counter-clockwise as far as it will go. Depress the lever (B) and rotate the table (C) to the 0° straight cut-off position, release the lever (B), and tighten the locking knob (A). NOTE: This saw incorporates a new slotted plate design feature (D) Fig. 6 with location adjustment screws (E) for fine-adjusting the cutting angle.
CONSTRUCTING WORK SUPPORT EXTENSIONS Work supports can be made easily for the miter saw. Fig. 10 illustrates the miter saw mounted to two standard 2 x 4’s (A). Fasten the grooves in the two mounting legs (B), to the 2 x 4’s, using four screws through the four holes in the mounting legs. The length of the 2 x 4’s (A) can vary, depending on preference. The distance from the top of the 2 x 4’s (A) to the compound miter saw table is 3 1/2”.
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. 15 clockwise to tighten the fit (counter-clockwise to loosen 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.
TILTING CUTTINGHEAD FOR BEVEL CUTTING DISCONNECT MACHINE FROM POWER SOURCE. A D A C B H Fig. 22 Fig. 23 IMPORTANT: Move the sliding fence to the left or right to provide clearance for the blade and guard. The DEGREE of tilt determines how far to move the sliding fence. Refer to the section “ADJUSTING SLIDING FENCE.” 1. 2. 3. The cuttinghead of your compound miter saw can be tilted to cut any bevel angle from a 90° straight cut-off to a 48° bevel angle left. Raise bevel lock lever (A) Fig. 22.
DISCONNECT THE MACHINE FROM THE POWER SOURCE. 1. 2. 3. 4. Position the bevel detent plate so that the desired angle (A) Fig. 25 is exposed. Lift the front handle (A) Fig. 26 to disengage the bevel lock. Tilt the cuttinghead left until it stops on the plate (B) Fig. 25. To adjust, loosen the pin locking set screw (C) Fig. 27 (shown from the rear), located on the side of the trunnion and rotate the bushing (B) to the desired location.
ADJUSTING LOWER BLADE GUARD This machine incorporates a blade guard (A) Fig. 32A to cover the rear section of the blade. After an extended period of use, the movable lower blade guard may not operate smoothly when the cuttinghead is lowered. This can be corrected by adjusting nut (B) until the lower blade guard moves freely. Overtightening the nut could impair guard movement. NOTE: This unit has been designed with an articulating rear guard.
CUTTING BOWED MATERIAL 1. 2. Check the workpiece. If it is bowed, position the workpiece on the table as shown in Fig. 36. When the workpiece is positioned the wrong way (Fig. 37), it will pinch the blade near the completion of the cut. INCORRECT CORRECT Fig. 36 Fig. 37 CUTTING CROWN MOULDING Make sure that the fence is clear of the guard and blade before operating the saw. CUTTING CROWN MOULDING One of the many features of the saw is the ease of cutting crown moulding.
MAINTENANCE Disconnect the machine from the power source. CHANGING THE BLADE 1. 2. 3. 4. Use only 12" diameter blades (with 1" arbor holes) that are rated for 5000 RPM or higher. Use the supplied wrench to loosen screws (A) Fig. 42. NOTE: One screw is located under the arbor cover arm. Rotate the arbor cover (C) Fig. 43, and move the guard (D) Fig. 43 to the rear, exposing the arbor screw (E). Remove the arbor screw (E) Fig.
BRUSH INSPECTION AND REPLACEMENT Before inspecting brushes, disconnect the machine from the power source. Brush life varies, depending on the load on the motor. Check the brushes after the first 50 hours, or after a new set of brushes has been installed. After the first check, examine them about every 10 hours. The brush holders (A) Fig. 45 are located on the motor housing opposite each other. Remove the brush holder cap (A) Figs. 45 and 46, and remove the brushes for inspection.
Two Year Limited New Product Warranty Delta will repair or replace, at its expense and at its option, any new Delta machine, machine part, or machine accessory which in normal use has proven to be defective in workmanship or material, provided that the customer returns the product prepaid to a Delta factory service center or authorized service station with proof of purchase of the product within two years and provides Delta with reasonable opportunity to verify the alleged defect by inspection.
