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-place article number on the nameplate of the
tool.
Clean the screen of the air inlet
regularly. For this purpose, un-
screw the hose nipple
2
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 pre-
vent this, a few drops of motor oil should
be placed in the air inlet
3
. Reconnect 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 proce-
dure 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.
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).
After the first 150 hours of operation, the gearbox
should be cleaned and lubricated by an authorized
service center. This process should be then per-
formed after every 300 hours of operation. After each
cleaning, it should be lubricated with special gearbox
grease.
Special gearbox grease 225 ml . . . . . 3 605 430 009
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.
