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. WARNING: Before performing any maintenance, make sure the tool is unplugged from the power supply and the switch is in the off position. Failure to heed this warning could result in serious personal injury. 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 may result in serious personal injury.  Keep your band saw clean.  Remove sawdust from the inside frequently.  Do not allow pitch to accumulate on the saw table, blade guides, or thrust bearings. Clean them with gum and pitch remover.  Apply a thin coat of automobile type wax to the saw table's top so the wood slides easily while cutting. 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. MOTOR/ELECTRICAL  Frequently vacuum or blow out sawdust from the motor. TIRES Cleaning tires:  Pitch and sawdust accumulates on tires and needs to be removed with a fine wire brush or a piece of wood. Do not use a sharp knife or any kind of solvent. Replacing tires:  Open front cover and remove saw blade. See section on Installing and Adjusting the Blade, page 13.  Pry the worn tire away from the wheel carefully.  Stretch the new tire around the wheel.  Replace the saw blade and close the front cover. BRUSH See Figure 21, page 22. There is a brush located inside the saw housing next to the wheel. It helps protect the tire and wheel by brushing off saw dust. As the brush becomes worn, it will need to be adjusted or replaced.  Remove the screw and washer then pull the brush off.  Place the new brush in the groove.  Reinstall using the washer and screw. 15 - English
