21DRILLING METALTo reduce the risk of injury, tighten all lock handles before starting the machine. Loss of control of theworkpiece can cause serious injury.Use clamps to hold metal workpieces. Never hold the workpiece in your bare hand. The drill bit can seize the work atany time, especially when breaking through the workpiece and cause damage to the machine or injury to you. The drillbit will break if the workpiece strikes the column.Clamp the workpiece firmly. Any tilting, twisting, or shifting results not only in a rough hole, but also in bit breakage.For flat work, lay the workpiece on a wooden base and clamp it firmly against the table to prevent it from turning. If theworkpiece is of irregular shape and cannot lay flat on the table, securely block or clamp it.TROUBLESHOOTINGFor assistance with your machine, visit our website at www.deltaportercable.com for a list of service centers or call theDELTA Machinery help line at 1-800-223-7278 (In Canada call 1-800-463-3582).MAINTENANCETo reduce the risk of injury, turn unit off and disconnect it from power source before installing andremoving accessories, before adjusting or when making repairs.
