is not operating accurately and smoothly, immediately stop the motor and make repairs before attempting sanding operations. 28. Keep work area clean. Cluttered areas and benches invite accidents. 29. Use the right tool. Don't force tool or attachment to do a job for which it was not designed. 10. Always hold the work firmly on the table when sanding on the belt or disc. The only exception is curved work performed on the bottom wheel. 30. Use proper extension cord.
25. When installing a new disc, be certain the disc is accurately centered on the drive wheel. Failure to do so could cause an unbalanced condition. WARNING: Some dust, fumes and gases created by power sanding, sawing, grinding, drilling, welding and other construction activities contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

permanent ground such as a properly grounded outlet box. It is recommended that the sander be connected to a minimum 15-amp circuit with circuit breaker or fuse. If using fuses, they should be time-delay fuses marked “D”. Local codes take precedence over recommendations. 7.1 GROUNDING INSTRUCTIONS 1. All Grounded, Cord-connected Tools: This tool must be grounded.
8.2 Sanding belt tracking Table 2 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number (AWG), the heavier the cord. 1. Turn sander OFF. 2. Move sanding belt by hand to check tracking. If belt migrates to one side or the other, adjust as follows. Amp Rating 3. Loosen wing nut (E, Figure 8-1). 4. Turn knob (F) while moving the belt until belt completely covers drive wheel and stays centered.
Contour sanding (horizontal position) – Contoured workpieces can be sanded over the drive wheel. Open the end cover and secure it by attaching its hook to the strap, as shown in Figure 9-1. Adjust tool rest and tighten in place. Figure 9-2: safety key (non-VS models only) IBDG-248VS, IBDG-436VS: Press on/off button on keypad (Figure 9-3) to start or stop. Press either of the numbered buttons to start machine at the designated speed. Press arrow buttons to change rotation speed in 100 RPM increments.
10.0 User-maintenance For safety, turn switch to OFF and remove plug from power source outlet before performing maintenance on the grinder/sander. If the power cord is worn, cut or damaged in any way, have it replaced immediately. 10.1 Cleaning Metal shavings may still be hot from recent sanding operations. Make sure shavings and debris are cold before cleaning the machine. Use a brush or rag to clear shavings, not bare hands. Figure 10-1: sanding belt tension 10.

12.0 Troubleshooting IBDG series Belt/Disc Sander 12.1 General mechanical and electrical problems Some corrections may require a qualified electrician. Symptom Possible Cause Correction Motor will not start. No incoming power. Verify that plug is properly inserted into receptacle. If so, check main panel for tripped breaker or blown fuse. Non-variable speed models: Safety key is missing. Make sure safety key is inserted. Wheel(s) cannot rotate because of obstruction.
Symptom Possible Cause Correction Motor stalls (cont.) Short circuit in motor or loose connections. Inspect connections on motor for loose or shorted terminals or worn insulation. Low voltage. Correct the low voltage conditions. Incorrect fuses or circuit breakers in power line. Install correct fuses or circuit breakers. Motor overloaded. Reduce load to motor; do not press so hard. Low line voltage. Check power line for proper voltage. Loose connections. Inspect connections. Motor overload.
12.2 Digital readout error codes (Variable speed models) Message Possible Cause Correction * OCL Internal electronic overload has been tripped. Do not overload motor; reduce pressure of workpiece against wheels. OH IGBT protection activated. Inspect wire connections to U/V/W for possible short circuits. Verify that motor rating corresponds to AC motor drive output power. OE Excessive input voltage (exceeds AC driver limits). Use correct voltage.
