of these are: gasoline, carbon tetrachloride, chlori- nated cleaning solvents, ammonia and household detergents that contain ammonia.
Care of Blades
Blades become dull even from cutting regular lumber. If you find yourself forcing the saw forward to cut instead of just guiding it through the cut, chances are the blade is dull or coated with wood pitch.
When cleaning gum and wood pitch from blade, unplug the saw and remove the blade. Remember, blades are designed to cut, so handle carefully. Wipe the blade with kerosene or similar solvent to remove the gum and pitch. Unless you are experienced in sharpening blades, we recommend you do not try.
Tool Lubrication
Your Bosch tool has been properly lubricated and is ready to use. It is recommended that tools with gears be regreased with a special gear lubricant at every brush change.
Periodically lubricate moving parts with a silicone, or light oil spray. Do not use grease because it tends to attract and hold sawdust.
Bearings
All bearings in this tools are lubricated with a suffi- cient amount of high grade lubricant for the life of the unit under normal operating conditions. No further lubrication is required.
