MAINTENANCE WARNING: When servicing, use only identical replacement parts. Use of any other parts can create a hazard or cause product damage. WARNING: Always wear eye protection with side shields marked to comply with ANSI Z87.1 during product operation. If operation is dusty, also wear a dust mask. 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 can 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 product 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 product using compressed air. LUBRICATION All of the bearings in this product 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. BRUSH REPLACEMENT See Figure 16, page 15. NOTE: This saw is equipped with two externally accessible brushes located on either side of the saw housing. Unplug the saw. WARNING: Failure to unplug the tool could result in accidental starting causing possible serious injury. Remove brush caps using a screwdriver. Remove brush assemblies. Check for wear. Replace both brush assemblies when either has less than 1/4 in. length of carbon remaining. NOTE: Do not replace one side without replacing the other. Reassemble using new brush assemblies. Make sure curvature of brush matches curvature of motor and that brush moves freely in brush tube. Reassemble by reversing the steps listed above. Tighten brush caps securely. Do not over tighten. WHEEL MAINTENANCE If wheel cutting ability deteriorates or becomes slow, the wheel may need resurfacing. Cutting a brick paver will resurface the wheel and improve wheel cutting ability.
