Unpacking The box included in your shipment contains the legs, hardware and wrenches. Please use the following procedure to remove the box: Remove the elevating handle from the hardware bag fastened to the carton top. Install handle on shaft located at the lower right side of saw frame.
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.
General Safety Precautions 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 motor on. Keep the blade sharp and properly set. Hold material firmly against the guide strip when cutting.

!!! CAUTION !!! FOR ILLUSTRATION PURPOSES ONLY ,THE LOWER GUARD HAS BEEN REMOVED FOR THE PHOTOS USED IN THIS MANUAL. IN ACTUAL USE BOTH UPPER AND LOWER GUARDS MUST REMAIN IN PLACE FOR SAFE CUTTING OPERATION. Revolving the Motor Vertically in the Yoke Raise the arm to allow the saw blade sufficient clearance above the table top.
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 latch and tilt the motor in the yoke. The bevel angle is shown on the bevel scale. Lock the bevel latch and clamp.

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. Han- dling during shipment may cause some misalignment and the following information will enable you to correct any cutting inaccuracy you discover.

Adjustment of the Rollerhead to Arm (cont’d) Retighten the locking set screw securely to a required torque of 90-100 inch/lbs., after adjusting each eccen- tric. Replace the end cap If any of the top rollers do not revolve when in contact with the top track it will be necessary to remove the entire carriage to closely check each roller bearing.

To Square Saw Blade with the Table Top 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: Release the bevel clamp handle (A) and bevel latch (B).
Page 14
To Adjust for “Heel” (Saw Blade Not Parallel to Arm) (cont’d) Second - Adjust at the 0 Bevel Position Put the motor into 0 bevel position. Engage bevel latch (A, Fig. 7) and bevel clamp (B). Cross cut a piece of material and determine the side of the cut on which the teeth are heeling.
Page 15
Bevel Stop Rod The bevel stop rod (A) is a device mounted on the roller- head to prevent the blade from contacting the base when the bevel cuts are being made; particularly with 20” blades. A socket head cap screw (B) locks the rod into position. BEFORE MAKING BEVEL CUTS ALWAYS BE CERTAIN THE BEVEL STOP ROD IS POSITIONED SO THE BLADE CLEARS THE BASE WITH THE MOTOR IN ITS REAR POSITION.
