The Mill-Drill must be checked for proper lubrication before operating. See sect.9.3. Repair or replace immediately. 6.
If the tool must be reconnected for use on a different type of electric circuit, the reconnection should be made by qualified service personnel; and after reconnection, the tool should comply with all local codes and ordinances. Table 2 shows recommended size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord. Ampere Rating 6.2 Voltage conversion To convert machine to 230 volt input operation: 1.
6. 7. Grasp arbor with one hand while loosening drawbar with the other. Continue to loosen drawbar until arbor can be withdrawn from spindle. Wipe out spindle with clean, dry rag. The scales can be adjusted by loosening screw (T1) and rotating scale to align with indicator. The stops (T2) can be adjusted to any point along the longitudinal axis. Retighten screws after positioning. Wipe new arbor with clean, dry rag and push arbor into spindle. Thread drawbar into arbor from above.
2. Rotate spring cap clockwise to decrease spring tension; counterclockwise to increase. 3. Tighten knob (A). Figure 8-1: operating controls (tapping model 45VSPFT shown) Figure 7-4: spindle return spring adjustment 8.0 Operation 8.1 Operating controls Refer to Figures 8-1 and 8-2. Depth stop and scale. All models: Turn scale ring (A1) until desired depth on scale aligns with indicator. Tighten lock handle (A2).
8.4 Manual fine feed Emergency stop (M). Push to stop all machine functions. To restart, rotate E-stop button clockwise until it disengages. Note: It is recommended that start/stop button (N) be used for normal spindle stoppage to prevent unnecessary wear on E-stop. See Figures 8-1 and 8-2: Spindle start/stop (N). Activates spindle rotation. Spindle speed (O). Sets spindle rotation speed within the pre-selected range. 8.
1. Turn off machine – spindle stopped. 9.1 General maintenance 2. Adjust depth stop to highest position. 1. 3. Engage fine feed handwheel, and turn it to set milling height. After each use, wipe down machine with a clean rag and apply light coat of oil to exposed metal surfaces. 4. Tighten spindle lock (C, Figure 8-1) at desired height. 2. Periodically check for backlash, or “play”, in table and head movements.
9.3 Lubrication Note: Spindle bearings are sealed and do not require further lubrication.
10.0 Troubleshooting JMD-45VS series Mill-Drills Table 5 Symptom Possible Cause Correction* Motor will not start. Low voltage. Check power line for proper voltage. Open circuit in motor or loose connection. Switch failure. Inspect all lead connections on motor for loose or open connections. Inspect switch, replace if needed. Motor fault. Repair or replace motor. Short circuit in line cord or plug. Inspect cord or plug for damaged insulation and shorted wires.
Symptom Possible Cause Correction* Fine feed not smooth, or won’t engage properly. Excessive vibration or noise. Fine feed handwheel loose. Tighten set screw. Improper worm gear engagement. Replace worm gear elements as needed. Loose motor fan. Inspect and tighten. Spindle improperly lubricated. Maintain proper machine lubrication. Gear not properly meshed. Spindle runout or loosening due to bearing misadjustment or failure. Motor imbalance.
