WARNING: Always wear eye protection with side shields marked to comply with ANSI Z87.1. Failure to do so could result in objects being thrown into your eyes resulting in possible serious injury. GENERAL MAINTENANCE Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc. WARNING: Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc., come in contact with plastic parts.

POWER SUPPLY CORD REPLACEMENT If replacement of the power supply cord is necessary, this must be done by an authorized service center in order to avoid a safety hazard. WHEEL REPLACEMENT See Figure 12, page 14. If you must replace a grinding wheel, be sure to obtain one with a safe rated speed at least as high as the "no load speed" RPM marked on the data plate of the grinder and which is marked to comply with ANSI B7.1. To replace the grinding wheel:  Unplug the grinder.  Remove the wheel cover by loosening the screws.  Loosen the wheel nut in a clockwise direction for the left side and a counterclockwise direction for the right side.  Remove the outer flange and grinding wheel.  To install a new grinding wheel, reverse the above procedure. NOTE: Be sure the grinding wheel and outer flange are properly seated on the spindle shaft. INSTALLING WIRE WHEEL (NOT INCLUDED) See Figure 13, page 15. When replacing the grinding wheel with a wire wheel, it is necessary to place a spacer on the spindle shaft BEFORE installing the inner flange, wheel, outer flange, and wheel nut. LUBRICATION All of the bearings in this tool are lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrication is required. NOTE: ILLUSTRATIONS START ON PAGE 11 AFTER FRENCH AND SPANISH LANGUAGE SECTIONS. 10 - English
