Align flat side of shaft with the set screw on the table crank handle. Tighten set screw using the 4 mm hex wrench. Fig. 6 5.
ASSEMBLY 8. Attach the three feed handles by screwing them into the threaded holes in the hub. 9. Using the pre-drilled holes in the base, mount your drill press securely on a sturdy surface such as a work stand, workbench or counter top. See Figure 9. If your drill press is to be used in a portable application, it is recommended that you fasten it permanently to a mounting board that can be easily clamped to a workbench. WARNING: Do not connect to power supply until assembly is complete.
ADJUSTMENTS Bevel Adjustment See Figures 11 and 12. Your drill press is equipped with a tilting table that allows you to drill angled holes. The table can be tilted left or right, from 0-45 degrees. To tilt the table, loosen the large hex bolt located underneath the table. Use the bevel scale to tilt table to the desired angle, then tighten hex bolt. SCALE SET HANDLE Fig. 13 CHANGING SPEEDS See Figure 14. The spindle speed is determined by the location of the belt on the pulleys in the pulley housing.

OPERATOR'S MANUAL 10 in. (254 mm) Drill Press Model DP101 EXTENSION CORD CAUTION **Ampere rating When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to handle the current the tool will draw. An undersized cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to determine the minimum wire size required in an extension cord. Only round jacketed cords should be used.
