MAINTENANCE WARNING: When servicing, use only identical replacement parts. Use of any other part may 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. CLEANING  Unplug the planer. Sawdust buildup and other debris can cause the tool to plane inaccurately. Periodic cleaning and waxing is needed for accurate, precision planing. Do not allow sawdust to accumulate on the planer. Clean the dust hood after each use. DANGER: Rotating blades under dust hood. In order to avoid ­personal injury, keep fingers away. 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, carbon dust, etc. WARNING: Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc., come in contact with plastic parts. They contain chemicals that can damage, weaken, or destroy plastic. 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. Moving parts should be cleaned regularly with penetrating oil and lubricated with a light coating of medium-weight machine oil. Paste wax should be applied to the planing table surface to ease the movement of workpieces across it, but be careful not to use so much that it will be absorbed into the wood and interfere with staining. Check feed rollers after each use for resin buildup, because feed rollers must be clean to be effective. If buildup occurs, use a mild, nonflammable tar and pitch remover. BLADE wrench storage See Figure 18, page 25. For your convenience, the blade wrench can be stored in the left hand side panel. Dispose of used blades properly. Wrap blades in tape before disposal to avoid accidental injury. WARNING: To ensure safety and reliability, all repairs should be performed by a qualified service technician at an authorized service center to avoid risk of personal injury. motor/electrical The universal motor is easy to maintain but must be kept clean. Do not allow water, oil, or sawdust to accumulate on or in it. The sealed bearings are permanently lubricated and need no further attention. 17
