Electrical Hookup - Recommended Copper Wire Sizes (A.W.G.) To obtain maximum efficiency from your saw motor, the feeder wire from the power source to the machine should comply with the table below. Motor Horsepower 1 Phase 3 Phase 3 Phase 200-240 V 200-240 V 440-480 V 3 6 6 — 3 — 4 6 NOTE: This table is based on 60-100’ distances from power supply. Less than 60’ may use one even size smaller (high number = smaller size); 100-160’ use one even size larger, over 160’ use two even sizes larger.
Overload Protection Your saw is equipped with automatic reset thermal overload protection. To restart after thermals have tripped, wait until the motor cools, then press the saw start button. If overloads continue to trip, the machine is being overloaded. Do not continue to operate under these conditions. Find the trouble and correct it—see the electrical trouble shooting section of this manual.
General Safety Precautions 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Be sure the blade rotates clockwise when facing the saw from the left side. Blade must rotate to the front of the saw. Be sure all clamp handles are tight before turning on motor. Keep the blade sharp and properly set. Hold or clamp the material firmly against the guide strip when cutting. Be sure the blade and arbor collars are clean and the recessed side of the collars are against blade. Never oil or grease arm tracks or motor.
Operating Instructions !!! CAUTION !!! BOTH UPPER AND LOWER GUARDS MUST REMAIN IN PLACE FOR SAFE CUTTING OPERATION. Control Locations A. B. C. D. E. F. G. H. I. J. K. L. M. N. O. P.
!!! CAUTION !!! BOTH UPPER AND LOWER GUARDS MUST REMAIN IN PLACE FOR SAFE CUTTING OPERATION. Rotating the Motor to Bevel Cutting Position Raise the arm to allow the saw blade sufficient clearance above the table top. Release the bevel clamp handle (A) and pull the bevel index pin. The motor can now be moved to a bevel position as indicated on the bevel scale. Lock the motor by releasing the bevel index pin (possible only at 0o, 45o and 90o) and by locking the bevel clamp handle.
Bevel Cutting Lock the arm in the cross cutting position. Raise the motor by rotating the elevation crank. Release the bevel clamp and the bevel index pin and tilt the motor in the yoke. The bevel angle is shown on the bevel scale. Release the bevel index pin and lock the bevel clamp. Lower the arm into cutting position. Adjust the arm stop to assure clearance between blade and base. Pull the saw through as you would for cross cutting.
Maintenance Adjustments and Alignments Caution! Disconnect and lockout power supply before making any adjustments or alignments. Your saw has been completely assembled, aligned and tested at the factory...then partially disassembled for shipment. Handling during shipment may cause some misalignment and the following information will enable you to correct any cutting inaccuracy you discover. These adjustments may also be necessary after a period of use. (See preventive maintenance) Important ...
Adjustment of the Rollerhead to Arm (cont’d) 5. Insert socket wrench into bottom of bearing shaft (C) and turn until the bearing touches the arm track on both top and bottom radii. Repeat for both shafts. Bearings should be tightened only so that they roll and do not slide. Replace the end cap and return saw to normal position. 6. Note-Too much pressure on the roller bearings will cause excessive and unnecessary wear in the parts and make the carriage work harder.
To Square Saw Blade with the Table Top Pull the saw to middle of table and lock into place. Make sure the tabletop is level and place a steel square against the side of the blade; the square should be against the gullets and not the teeth of the blade. If the blade is not square to the tabletop: 1. 2. Remove two screws holding the bevel pointer. Loosen the two sockethead cap screws (A) located on the outside of the dial plate. Release the bevel clamp handle (B).
Adjusting Crosscut Travel Parallel to Arm Tracks (continued) After making the left and right adjustments, tilt the motor to a 45o bevel cutting position and make cuts in a 2”x 4” piece of material. If tooth marks appear the motor is too high or low in the rear yoke: A. If marks are made on the bottom side of material: 1. Release the bevel clamp handle. 2. Loosen the right and bottom lock nuts on the rear yoke trunion bushing. 3.

Changing the Motor Voltage WARNING—DISCONNECT AND LOCKOUT POWER BEFORE SERVICING If your machine requires a different voltage, follow the instructions below. The motor will need to be rewired according to the diagrams below. The thermal overloads must be reset or replaced with the proper pieces to maintain thermal motor protection. Instructions for Changing the Motor Voltage 1) 2) 3) 4) Disconnect and lockout power– Electrical shock could occur if this is not done.
Alignment Guide for Accurate Cutting The following guide is provided for your convenience. A saw that is not properly adjusted will not yield the desired accuracy and quality of cut. It should be noted any adjustment made will effect another, therefore it is best to perform all of the adjustments when correcting any one problem.
PROBLEM Saw blade or dado blades tend to push lumber to one side when cross cutting POSSIBLE CAUSE − − − − − − − Cut depth varies from one end of stock to the other 450 bevel cut not accurate Column too loose in base Too much play between arm and column Rollerhead too loose in arm Yoke too loose when clamped to rollerhead Fence not straight Dull blade or cutters − − − Tabletop not parallel with arm − Saw blade not perpendicular to tabletop Column too loose in base − − − − − − Saw tends to advance
