2. Remove arbor nut (A) Fig. 29, and outside blade flange (B). NOTE: THE BLADE IS TO BE ASSEMBLED BETWEEN THE TWO BLADE FLANGES (B) AND (C) WITH THE RECESSED SIDES OF THE FLANGES AGAINST THE SAW BLADE. 3. Assemble the saw blade (D) Fig. 30, between the two blade flanges making sure the teeth of the saw blade are pointing down at the front. 4. Assemble arbor nut (A) Fig. 30 to shaft and tighten with wrench (E) Fig. 30, while keeping arbor shaft from turning with other wrench (F). C B A Fig. 29 D A F E Fig. 30 13 5. Remove screw, flat washer and spacer (G) Fig. 31, that fasten the front inside leaf guard (H) to front end of blade guard (J). Assemble blade guard (J) to motor assembly with locking rod (K). 6. Reassemble leaf guard (H) Fig. 31, to blade guard (J) using screw, flat washer and spacer (G). K J H G Fig. 31 7. Fig. 32, illustrates the blade guard assembly attached to the motor assembly. Fig. 32 NOTE: The lower retractable blade guard provides operator protection in an axial direction to the saw blade. Care must be taken to eliminate potential hazards of the lower blade guard. A) KEEP YOUR HANDS AWAY FROM THE GUARD. As the blade cuts, the guard will lift and leave part of the blade exposed. B) SHUT OFF POWER BEFORE FREEING A JAMMED LOWER GUARD. The guard can get jammed in previous kerfs in table or fence. Always anticipate the path of the guard. C) USE CAUTION when making bevel cuts to be sure the lower guard is never pinched towards the blade. D) THE LOWER GUARD CAN JAM AGAINST THE FENCE DURING NARROW IN-RIPS. Should the guard jam against the fence, disconnect the saw from power source, wait for the blade to stop, then lift the blade guard and rest it on top of the fence. 14 OPERATING CONTROLS AND ADJUSTMENTS Every Delta Radial Saw is thoroughly tested, inspected and accurately aligned before leaving the factory, and when delivered is ready for operation after it is assembled. However, regardless of the care with which this or any piece of fine machinery is manufactured, inspected and shipped, it is possible that rough handling in shipment may make minor adjustments necessary. CAUTION: ALWAYS DISCONNECT SAW FROM POWER SOURCE BEFORE MAKING ANY ADJUSTMENTS. ON/OFF SWITCH The On/Off Switch (A) Fig. 35, is conveniently placed at eye level on the front of the overarm. IMPORTANT: When the tool is not in use, the switch should be locked in the “OFF” position to prevent unauthorized use. This is achieved by pressing in and holding the switch (A) down in the “OFF” position while turning key (B) to the lock position; then remove key (B). ADJUSTING OVERARM COLUMN ASSEMBLY If side motion develops in the overarm, after extended use, it can be corrected as follows: 1. DISCONNECT TOOL FROM POWER SOURCE. 2. Loosen hex nuts (A) Fig. 36, and gib adjusting screws (B) and (C). 3. Adjustment to the column base is made by loosening hex nuts (D) Fig. 36, tightening or loosening bolts (E), until column base wraps around column securely and that the column can be raised or lowered without binding. Tighten locknuts (D). 4. After column base is adjusted, tighten screws (C) Fig. 36, against column gib until all side motion disappears in overarm. 5. Tighten hex nuts (A) and screw (B) Fig. 36. ADJUSTING YOKE CLAMP HANDLE The yoke clamp handle (A) Fig. 37, allows the yoke (B) to rotate to the rip or cross-cut positions. To reposition the cuttinghead, push yoke handle (A) to the rear and turn yoke (B) to desired position; to lock the yoke in position, pull yoke clamp handle toward you. If the yoke clamp handle (A) Fig. 37, does not lock the yoke completely, or does not lock in a convenient position, the handle can be adjusted as follows: 1. DISCONNECT TOOL FROM POWER SOURCE. 2. Remove blade guard assembly (C) Fig. 37, and saw blade. 3. Remove rear end plate from track arm and remove cuttinghead assembly (D) Fig. 37, from track arm. 4. Loosen yoke clamp handle (A) Fig. 37, and remove cotter pin (E). 5. Turn hex nut (F) Fig. 38, clockwise 60 degrees and replace cotter pin (E). 6. Replace cuttinghead to track arm and replace items removed in STEPS 2 and 3.

The ball bearings must ride smoothly and evenly against the track rods to do accurate work. If wear should ever develop in the track rods causing “play” between the ball bearings and the track rods, the ball bearings can be adjusted as follows: 1. DISCONNECT TOOL FROM POWER SOURCE. 2. Move the cuttinghead to the center of the track, and check to see if any play is present. 3. To adjust, place special wrench socket (A) Fig. 39, supplied with the saw, over hexagon nut, located underneath the carriage. Place one of the wrenches (B) supplied, on flats on special wrench socket (A) and...
