MAINTENANCE WARNING:  Empty all debris from the dust bag and ensure that the collar is free of debris. When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage.  Replace the dust bag. REPLACING BLADES See Figures 14 - 16, page 13. 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 The planer blades are reversible. When one edge becomes dull, the blade can be reversed so that the other side can be used. Always replace or reverse blades in pairs. Do not attempt to sharpen blades. If the blades in the planer show signs of becoming dull, chipped, or damaged in any way, replace them. When replacing the blades, use recommended replacement blade only, RYOBI part number 039821001057. 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: WARNING: Always wear heavy leather gloves and use caution when loosening blade screws and handling and/or changing blades. Blades are sharp and can cause serous personal injury. 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 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. CLEANING THE EXHAUST PORT AND EMPTYING THE DUST BAG See Figure 13, page 13. After using the planer for an extended period of time or when planing wet or green lumber, chips may build-up in the exhaust port and require cleaning. Chip build-up restricts air flow and causes the motor to overheat. Clean the exhaust port and empty the dust bag regularly.  Remove the battery pack.  Remove the battery pack.  Secure the planer in an upside-down position.  Loosen the three screws securing the blade on the blade holder by turning counterclockwise with the provided blade wrench. NOTE: Do not over-loosen the screws. If screws are too loose, alignment of the new blade will not be accurate. NOTE: Before removing the old blades, take notice of the direction of cut as well as how the tapered edge of the old blades are oriented. The tapered edge of the new blades must be in the same orientation as the original blades, with the tapered edge on the same side as the screw heads and the flat edge facing the cutter block.  Depress the spring-loaded blade guard.  Push the blade holder out of the cutter block assembly using the tip of a screwdriver.  Remove the old blade from the blade holder by sliding the blade out using the tip of a screwdriver. NOTE: If blade cannot be easily pushed out of blade holder after loosening blade securing screws, use a block of wood to break the blade loose from the blade holder with a short sharp blow. Then push the blade with a screwdriver to remove. If necessary, tap the block of wood sharply with a small hammer to break the blade loose.  Clean any sawdust or wood chips from around the blade area.  Remove the dust bag from the exhaust port.  Slide the new blade into the slot of the blade holder.  Clean the chip or dust build-up from the exhaust port of the planer with a small piece of wood. Do not use your hands or fingers.  Use a screwdriver to push the blade into the blade holder until it is centered into position.  Depress the spring-loaded blade guard. 8 - English
