Troubleshooting
Troubleshooting Guide - Electrical
Cleaning
To avoid accidents, always
disconnect the tool from the
power supply before cleaning or performing any
maintenance. The tool may be cleaned most
effectively with compressed air. Always wear
safety goggles when cleaning tools with
compressed air.
Ventilation openings and switch levers must be kept
clean and free of foreign matter. Do not attempt to
clean by inserting pointed objects through openings.
Check regularly to make sure the lower guard and all
moving parts are working properly.
Remove accumulated sawdust from working parts by
blowing with compressed air or wiping with a damp
cloth.
Certain cleaning agents and
solvents damage plastic parts.
Some
of
these
are:
gasoline,
carbon
tetrachloride, chlorinated 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
preventive
maintenance
performed
by
unauthorized
personnel may result in misplacing of internal
wires and components which could cause
serious hazard. We recommend that all tool
service be performed by a Bosch factory Service
Center or Authorized Bosch Service Station.
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 tool are lubricated with a sufficient
amount of high-grade lubricant for the life of the unit
under normal operating conditions. No further
lubrication is required.
