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. _k WARNING: Do not at any time let brake fluids, gasoline, petroleum-based 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 recommended 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. Only the parts shown on the parts list are intended to be repaired or replaced by the customer. All other parts should be replaced at a Sears Service Center. REPLACING THE BLADE See Figures 22 - 24. After extended use, the blade on your biscuit joiner may become dull and need replacing. If you accidentally hit a nail or other blunt object, it will break the carbide tips, which will require replacing the blade. • Unplug the biscuit joiner. • Remove the dust bag. • Place the biscuit joiner upside down on a workbench. • With a screwdriver, remove the four screws and wash- ers that connect the shoe to the front and rear assemblies. Remove the shoe. SHOWNWITHOUTDUSTBAG SCREW(S) SHOE Fig. 22 20
