The speed control handwheel is located on the left side of the drill head. An LED speed indicator is provided on the face plate on the drill head. 1. The head assembly must be locked to the column so the thrust produced by drilling will not force the head assembly up the column. 2. The work table must be locked to the column so it will not be forced down the column. 3. Be sure the belt is tightened to the proper tension. LED Speed Display 4.
Indication of Extreme Speeds and Feeds 4. Remove belt. (With speed control setting at the highest speed, the belt should be loose enough to remove.) A drill that splits up the web is evidence of too much feed or insufficient tip clearance at the center as a result of improper grinding. The rapid wearing away of the extreme outer corners of the cutting edges indicates that the speed is too high.
Adjustments Table Adjustment The table can be raised or lowered to accommodate the height of the component being drilled (refer to Figure 9). To raise or lower the table, loosen the lock handle. Then use the hand crank to move the table to the desired height. Then retighten the lock handle. Figure 9 – Table Adjustment Head Adjustment Change the radial position of the drill head only if the drill press base is secured to the floor.
Electrical 230 Volt Operation Referring to Figure 12: 115 Volt Operation If 230V, single-phase operation is desired, the following instructions must be followed: Referring to Figure 11: As received from the factory, your drill press is ready to run at 115-volt operation. This drill press, when wired for 115 volt, is intended for use on a circuit that has an outlet and a plug that looks like the one illustrated in (A).
Grounding Instructions Extension Cords Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your machine will draw. An undersized cord will cause a drop in the line voltage resulting in power loss and overheating. The table following shows the correct size to use depending on the cord length and name plate ampere rating. If in doubt, use the next heavier gauge. Remember, the smaller the gauge number, the heavier the cord.
Troubleshooting Problem Spindle does not turn. Spindle noisy. Drill stalls. Probable Cause Suggested Remedy Circuit breaker tripped. Reset circuit breaker. Branch circuit breaker tripped or fuse blown. Reset Open wire in switch circuit. Repair open circuit. Defective switch. Repair switch. Broken drive belt. Replace drive belt. Damaged spindle bearings. Replace bearings. Worn spline. Replace spline. branch circuit breaker/replace fuse. Worn drive belt. Check condition of belt.
