WARNING: To prevent an accident or personal injury, always turn off the switch and disconnect the power plug from the receptacle before mounting or dismounting the dado blade set.
Never attempt to stack dado blades thicker than 1/2" (12.7 mm) thick. Never use the dado set for
Take every precaution to prevent kickback of the workpiece. Feed workpiece slowly, especially when cutting deep or wide grooves. When the dado head is hidden from view while cutting, your hands should never be on top of the workpiece. When using a dado blade, the saw blade guard assembly must be removed since there is not cut completely through the wood which will allow the spreader to pass through the workpiece.
CAUTION: Use extreme caution when dado cutting.
Always stop the tool and wait for dado blade to come to a complete stop. Then simply withdraw the wood. Use a push stick. Use rip fence or miter gauge. Be alert for potential kickback conditions. Follow the dado blade set manufactures recommendations. When using a dado blade set, the depth of cut is not indicated by the pointer. To know the depth cut, you must measure it with a ruler. Be sure to place the saw blade guard assembly back in its original position and check adjustments when the dado cuts are completed.
A groove cut into the workpiece is called dado. This dado does not extend completely through the workpiece. The dado can be made in various widths and depths according to the need. A typical use for a dado is to make the groove for a shelf. A saw blade can be used to make a dado of any width by marking multiple cuts side by side. However, it is much easier to use a dado blade. The first has to small blades and a series of chips to the remove scrap between the blades. The second type consists of a small thick blade which is caused to wobble by its mounting hubs. This saw will accept dado blades of the cutter chip type to 6" (152
mm)in diameter and 1/2" (12.7 mm) in which. Most wobble type blades are too wide fit on the saw blade spindle safely. A dado blade requires a table insert which has wider opening. This dado insert is available as an optional accessory (refer to page 10). Purchase the dado blade set separately.
