Care of Blades
Blades become dull even from cutting regular
lumber. If you find yourself forcing the saw for-
ward 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. Remem-
ber, blades are designed to cut, so handle care-
fully. 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 sili-
cone, or light oil spray. Do not use grease be-
cause it tends to attract and hold sawdust.
Bearings
All bearings in this tool are lubricated with a
sufficient amount of high-grade lubricant for
the life of the unit under normal operating con-
ditions. No further lubrication is required.
