15. Keep safety guards in place at all times when the machine is in use. If removed for maintenance purposes, use extreme caution and replace the guards immediately after completion of maintenance. 1.0 IMPORTANT SAFETY INSTRUCTIONS 16. Check damaged parts. Before further use of the machine, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function.
1. Use proper extension cord. 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 product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 (see sect. 7.2) 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, the heavier the cord. 42.

5.0 Setup and assembly 5.1 Unpacking Separate all parts from the packing material. Check each part against sect. 5.2, Carton contents, and make certain that all items are accounted for before discarding any packing material. (Check grinder first to verify if any parts have been premounted.) 5.2 Carton contents Refer to Figure 4.
washers (L), through the tool rest (M), into the wheel housing. 5.5 Assembling eye shield brackets to spark guards Refer to Figure 5. Note: Spark guards (A) and eye shield brackets (D) are marked L for left side assembly and R for right side assembly. 1. Assemble the left spark guard and eye shield bracket using Figure 5 as a guide. Make sure spark guard and bracket are both marked L. 2. Install the right assembly in the same manner. 3. Install the right tool rest in the same manner. 4.
6.0 Electrical connections Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Failure to comply may cause serious or fatal injury. Electrical connections should be made by a qualified electrician in compliance with all relevant codes. This tool must be properly grounded.
Table 1 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. Ampere Rating On all models, when the stop button is pushed, the wheels may take a few moments to completely stop. Note: After extended operation, housing may be warm to the touch.
8.0 Adjustments 8.1 Eye Shield Tilt Adjustment 1. Loosen lock knob (A1, Figure 10). 2. Adjust eye shield (A2) to the desired tilt angle. 1. Loop a piece of string through the grinding wheel hole and suspend the wheel by holding up the string. 2. Tap the wheel with a piece of scrap wood or a wooden dowel. 3. A good wheel will "ring"; a defective wheel will "thud". Discard any wheel that does not "ring". An internal defect may not be apparent by visual inspection alone.
4. 9.4.1 Adjusting concentricity Stabilize wheel by holding opposite wheel firmly, or placing a wood wedge between wheel and tool rest. If the outside face is not rotating concentric to arbor, try shifting the wheel closer to arbor centerline before tightening the nut. Another method of achieving concentricity is the use of a wheel dresser. “Dressing” is the removal of the current layer of abrasive to expose a fresh surface.
9.5 Dressing the wheels 9.6 Wire wheel brushes Below is a general procedure for dressing a grinding wheel. Always consult the wheel dresser manufacturer’s instructions for specific information pertaining to the tool. Wire brushing provides a fast way to remove rust scale, burrs, and paint from metal. Use coarse wire brushes for hard cleaning jobs. Use fine wire brushes for polishing and finish work. When the brush tips become dull, reverse the brush on the grinder.
10.0 Troubleshooting the IBG series Bench Grinders Table 3 Symptom Possible Cause Correction * Motor will not start. Not connected to power source. Verify that plug is properly inserted into receptacle. Switch in Off position. Make sure safety key is inserted. Motor cord cut or abraded. Replace with new cord. Wheels cannot rotate because of obstruction. Unplug and turn grinding wheel by hand to ensure free movement. Restart. Plug on cord is faulty. Replace with new plug. Low line voltage.
Symptom Possible Cause Correction * Motor slows. 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. Reduce load to motor; do not press so hard. Electrical circuit overload; too many electrical machines running on same circuit. Turn off other machines and try again. Incorrect fuse or circuit breaker Have electrician upgrade service to outlet.
