6 MAINTENANCE AND SERVICE
Maintenance
Disconnect the air hose from the air supply be-
fore making any adjustments, changing acces-
sories, or storing the tool. Such preventive safety
measures reduce the risk of starting the tool acciden-
tally.
Should the tool fail in spite of careful manufacturing
and testing procedures, have the repairs performed by
an authorized customer service location for Bosch
power tools.
For inquiries and spare parts ordering, please include
the 10-digit order number on the nameplate of the
tool.
Clean the screen of the air inlet
regularly. For this purpose, un-
screw the hose nipple 1 and re-
move dust and dirt particles from
the screen. Then firmly remount
the hose nipple.

Water and dirt particles in the com-
pressed air cause rust formation and
lead to clogging of vanes, valves, etc.
To prevent this, a few drops of motor oil
should be placed in the air inlet 17. Re-
connect the tool to the air supply and
let the tool run for 5–10 s while catching the oil that
runs out with a rag. If the air tool is not used for a
longer time, this procedure should always be
performed.
All Bosch air tools that do not belong to the CLEAN se-
ries (a special kind of air motor that functions with oil-
free compressed air), require a small amount of lubri-
cating oil be mixed into the flow of compressed air.

Always sharpen the saw blades in pairs. Unscrew the
screws on the sharpener 24, so that you can clamp
the saw blades in the holder 23. The beveled sides of
the teeth have to be oriented toward the top (un-
ground side of the saw blades toward the bottom, so
that the writing on the saw blades is readable). Firmly
screw the saw blades in the holder 23.
Pass the whetstone 25 evenly over the bevels of the
two saw blades. Several motions with the whetstone
suffice to give the saw blades sharp points once again.
The saw blades have to be thoroughly cleaned before
they are reinstalled.
The compressed air oiler required for this is located at
the compressed air maintenance unit connected to
the tool (you may obtain further details on this from a
compressor manufacturer).
You should use SAE 10 or SAE 20 motor oil for direct
lubrication of the tool or for admixture at the mainte-
nance unit (compressor).

Clean the saw blades 7 and the saw blade guide 5
every 8-10 hours of operation. Remove deposits in
the saw blade guide by using the scraper 26 included
in standard delivery.
The motor vanes should be routinely inspected by
trained personnel and, if necessary, replaced.
Have maintenance and repair work performed
only by qualified specialists. In this manner, it can
be ensured that the safety of the tool is maintained.
Any Bosch customer service center can perform this
work quickly and reliably.
Dispose of lubricants and cleaning agents in an
environment-friendly manner. Comply with the
legal regulations.
