MAINTENANCE WARNING: When servicing, use only identical replacement parts. Use of any other parts could create a hazard or cause product damage. 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. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury. Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, we do not recommend using this tool for extended work on these types of materials. However, if you do work with any of these materials, it is extremely important to clean the tool using compressed air. 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. 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. GUARD REPLACEMENT See Figure 7, page 13. After extended use, the guard may become worn and need adjustment or replacing. Or, if you drop the angle grinder and damage the guard, it may be necessary to replace it. To replace the guard:  Unplug the angle grinder.  Depress spindle lock button and rotate flange nut with provided wrench until spindle locks.  Using the wrench provided, loosen and remove nut, grinding or accessory wheel, and disc flange from spindle if necessary. NOTE: To prevent damage to the spindle or spindle lock, always allow motor to come to a complete stop before engaging spindle lock.  Using a screwdriver, loosen the clamp screw.  Remove the guard.  Place the new guard on the shoulder of the bearing cap, aligning the arrow with the slot on the bottom of the angle grinder. NOTE: If the new guard will not fit, loosen the clamp screw until they slide over the bearing cap. Be sure the tabs on the guard are seated in the groove in the bearing cap.  Rotate guard to the correct position as shown in figure 4.  Tighten clamp screw securely.
