manual abstract
Consequently, it is not recommended that this tool be used for extended work on any fiberglass material, wallboard, spackling compounds, or plaster. During any use on these materials, it is extremely important that the tool is cleaned frequently by blowing with an air jet. WARNING: Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask. 13 MAINTENANCE MAINTENANCE LUBRICATION All of the bearings in this tool are lubricated with a suffi- cient amount of high-grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrication is required. CLEANING CHIP EXHAUST AND EMPTYING CHIP BAG See Figure 16. After using your planer for an extended period of time or when planing wet or green lumber, chips may build-up in the chip exhaust port and require cleaning. Chip build- up restricts air flow and causes the motor to overheat. Unplug your planer. WARNING: Check extension cords before each use. If damaged replace immediately. Never use tool with a damaged cord since touching the damaged area could cause electrical shock resulting in serious injury. EXTENSION CORDS The use of any extension cord will cause some loss of power. To keep the loss to a minimum and to prevent tool overheating, use an extension cord that is heavy enough to carry the current the tool will draw. A wire gage size (A.W.G.) of at least 16 is recommended for an extension cord 100 feet or less in length. When working outdoors, use an extension cord that is suitable for outdoor use. The cord's jacket will be marked WA. Fig. 16 WARNING: Failure to unplug your planer could result in accidental starting causing serious injury. BLADE REPLACEMENT See Figures 17, 18, 19, 20, 21, and 22. The blades in your planer are reversible. Therefore, they can be reversed when one edge becomes dull. Always replace or reverse blades in pairs. Do not attempt to sharpen blades. If the blades become dull, replace them. When replacing the blades, use recommended replace- ment blade only, Ryobi part number HPL50K-26. Blades are sharp, use extreme caution when replacing blades. Unplug your planer. WARNING: Failure to unplug your planer could result in accidental starting causing serious injury. Secure your planer in an upside down position. Using the blade wrench provided, loosen the three blade securing screws on the blade holder. See Figure 17. NOTE: Do not over loosen the screws.
