The JET Model J-2221VS and J-2223VS drill presses feature manual speed control. Models J2232AC and J-2234AC have inverter speed control. This manual contains procedures for both speed control versions. The manual provides separate instructions when differences in operation and maintenance exist. Operation and Set-Up Securing the Base The base of the drill press has four mounting slots; two slots on both sides of the base. The drill press should be level and rest solidly on the floor.
Raising the Drill Head and Table Slide a grommet onto the cord to be installed later in the control box hole, to prevent stress to the power cord. The drill press is shipped with the table and drill head supported by wooden blocks near the bottom of the column. The head is raised to the operating position using a strap and hoist, then secured to the column by tightening the hex cap screw. The table is raised to the desired position using the crank handle. See Adjustments section for more information. 1.
Operating Controls To avoid damage to the speed adjustment mechanism, the drive motor must be operating before attempting to adjust the speed setting. Manual Speed Control (Models J2221VS and J-2223VS) A speed shift lever is on the right side of the head (refer to Figure 2 for location). The handle is turned clockwise to increase spindle speed and counterclockwise to reduce speed. Refer to Figure 4. Spindle Selector Switch A three-position selector switch is provided at the left side of the drill head.
RPM Display Maintenance The spindle speed display shows the spindle RPM selected by the speed control knob. Replacement of Drive Belt Spindle Speed Knob Make sure to disconnect electrical power to the drill press to avoid the possibility of inadvertent operation and exposure to potentially lethal voltage levels. The SPINDLE SPEED knob is used to set the desired spindle speed (clockwise increases). Spindle Selector The SPINDLE selector switch is used to set the desired direction of spindle rotation.
. Secure small head cover to head cover using pan screws. b. Countershaft spindle and push rod: Lubricate with SAE 20 oil occasionally. 13. Set the drill press circuit breaker ON. c. Speed control handle cam: Clean and grease with medium cup grease annually. 14. Operate the drill press to verify correct operation.
3. Adjustments Operate drill press to verify that speed readout is operating correctly. Table Adjustment Operating Precautions Refer to Figure 8. The following operating and safety precautions must be observed in order to avoid harm to the operator or damage to the drill press. The table can be raised or lowered to accommodate the height of the workpiece. To raise or lower the table, loosen the table lock using the hand crank. Then use the hand crank to move the table to the desired height.
Indication of Extreme Speeds and Feeds Drilling Recommendations 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. A drill chipping or braking out at the cutting edges indicates that either the feed is too heavy or the drill has been ground with too much tip clearance.
Optional Equipment Coolant System Installation 1. Remove the large reservoir cover plate from the machine base. Tap 1/4-20 threads in the 4 pilot holes. 2. Install the cover plate back onto the machine base. 3. Insert the pump into the opening, utilize the screws from the small round cover plate to fasten the pump to the base. 4. Position the power switch and valve bracket on the spindle casting. Mark mounting hole locations and drill holes.
Troubleshooting Trouble Spindle does not turn. Spindle noisy. Drill stalls. Poorly drilled holes. Motor overheating. Table cannot be raised. No speed readout. Probable Cause Remedy Motor overload protector tripped. Press motor overload reset button. Circuit breaker tripped. Reset circuit breaker. Branch circuit breaker tripped or fuse blown. Reset branch circuit breaker/replace fuse. Open wire in switch circuit. Repair open circuit. Defective switch. Replace switch. Broken drive belt.
