▶ 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.
▶ Carbon Brushes
The brushes and commutator in your
tool have been engineered for many
hours of dependable service. To
maintain peak efficiency of the motor,
we recommend every two to six months
the brush es be examined. Only genuine
Bosch replace ment brushes specially
designed for your tool should be used.

Bearings which become noisy (due to
heavy load or very abrasive material cut -
ting) should be replaced at once to
avoid overheating or motor failure.
adequate size conductors that is
capable of carrying the current
necessary for your tool must be used.

regular lumber. If you find yourself
forcing the saw forward to cut instead of
just guid ing 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 sol vent to
remove the gum and pitch. Unless you
are experienced in sharpening blades,
we recommend you do not try.
