Working with the Straight Grinder
The choice of tool bit/accessory, such as mount-
ed grinding points or flap sanding wheels, de-
pends on the application case and area.
Your specialist shop/service center will support
you in choosing suitable tool bits/accessories.
For optimal working results, move the tool
bit/accessory uniformly back and forth applying
light pressure.
Excessive pressure reduces the capacity of the
pneumatic tool and leads to premature wear of
the tool bit/accessory.
Maintenance and Service
Maintenance and Cleaning
Disconnect the air hose from the air source
before making any adjustments, changing
accessories, or storing the pneumatic tool.
Such preventive safety measures reduce the
risk of starting the pneumatic tool acciden-
tally.
Regularly measure the no-load speed of the
grinder spindle. If the measured value is
more than 10 % above the listed no-load
speed n (see "Technical Data"), have your
0
pneumatic tool checked by a service loca-
tion for Bosch power tools. In case of too
high no-load speeds, the tool bit/accessory
can burst apart; for too low no-load speeds,
the working performance is reduced.
Should the pneumatic 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 pneumatic tool.
Clean the screen of the air inlet regularly. For
this purpose, unscrew the hose nipple 3 and re-
move dust and dirt particles from the screen.
Then firmly remount the hose nipple.
To prevent damage to the internal valve compo-
nents of the tool, you should use an open-end
spanner (size 22 mm) to apply a counterforce at
the protruding connector of the air inlet 2 when
screwing/unscrewing the hose nipple 3.
Bosch Power Tools
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
engine oil should be placed in the air
inlet 2. Reconnect the pneumatic tool to the air
supply (see "Connection to the Air Supply",
page 23) and let the tool run for 5 – 10 s while
catching the oil that runs out with a rag. If the
pneumatic tool is not used for a longer time,
this procedure should always be performed.
All Bosch pneumatic tools that do not belong to
the CLEAN-series (a special kind of air motor that
functions with oil-free compressed air), require a
small amount of lubricating 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 pneumatic
tool (you may obtain further details on this from
a compressor manufacturer).
For direct lubrication of the air tool or when
adding oil to the filter/regulator-lubricator, use
SAE 10 or SAE 20 engine oil.
The motor vanes should be routinely inspected
by trained personnel and, if necessary, replaced.
Have maintenance and repair work per-
formed only by qualified specialists. In this
manner, it can be ensured that the safety of
the pneumatic tool is maintained.
Any Bosch customer service center can perform
this work quickly an reliably.
Observe all applicable environmental regula-
tions when disposing of old grease and sol-
vents.
