Assistance will be required when assembling. Before adjustments are made, ensure that the machine is SWITCHED OFF AND UNPLUGGED. Also make sure all locking handles and securing screws are FULLY TIGHTENED when adjustments are completed.
Installing the Chuck 1. With the Chuck Guard lifted clear of the spindle nose, slide the work table up the column to within 6” of the spindle. 2. Open the jaws of the chuck to their maximum width, using the Chuck Key supplied. 3. Put a piece of scrap wood on the table to protect the Chuck Nose. 4. Ensuring all parts are thoroughly clean and dry and burr free, insert the arbor (#14) firmly into the end of the chuck.
Before adjustments are made, ensure that the machine is SWITCHED OFF AND UNPLUGGED. Also make sure all locking handles and securing screws are FULLY TIGHTENED when adjustments are completed. TO ADJUST THE TABLE The table is capable of moving in four directions (see Figure 3). 1. Raise or lower the table by slackening off the arm locking handle (A) and turning the crank (C) CLOCKWISE TO RAISE and COUNTER CLOCKWISE TO LOWER. 2. Swivel the table about the column by slackening off the arm locking handle.

Drill Speed Table Note: Spindle Belt M24, Motor Belt M25 The table below shows the belt arrangements for given drill speeds (a full chart is also located on the inside of the pulley cover). After Operation 1. Remove all residue from the machine and thoroughly clean all surfaces. 2. Make sure all components are dry and machined surfaces lightly oiled. 3. Remove drill bits and store in a safe place. 4. Child-proof the machine and work area.
Extension Cords Your tool has a three-prong plug, therefore you must use a three-prong extension cord. Only use rounded jacket extension cords listed by the Underwriters Laboratories (UL). The extension cord must have a minimum wire size depending on the amperage of the tool and the length of the extension cord. This size is determined by its AWG (American Wire Gauge) rating. The smaller the gauge, the greater the cable’s capacity.
