Maintenance And Service - Bosch ANGLE EXACT 6 Operating Instructions Manual

LED Indicators
Battery Condition Indicator
If the charging of the battery 11 is necessary,
the LED indicator 10 blinks green. You can
still use the power tool for approx. 6–8
screwing actions.
If the LED indicator lights red, the capacity is no longer
adequate for another screwing action. The power tool
can no longer be switched on. The switch-on lock re-
mains active until a charged battery is inserted.
A considerably shortened operating time of the power
tool after each charging indicates that the battery must
be replaced soon. Dispose of the used battery in ac-
cordance with the legal/country-specific regulations.
Screwing Action Indicator
When the pre-set torque is reached, the
switch-off coupling responds. The LED indi-
cator 9 lights green.
If the pre-set torque is not reached, the LED indicator
9 lights red and an acoustical signal sounds. The
screwing action must be performed again.
Repeat Protection
If the switch-off coupling responds for a screwing ac-
tion, the motor switches off. Switching on again is
possible only after a 0.7 second delay. In this manner,
an unintentional re-tightening of an already seated
screw is avoided.
Maintenance
Remove the battery from the power tool before ad-
justments are made to the tool, accessories are
changed or the tool is stored. This safety measure
prevents the unintentional switching on of the power tool.
When battery pack is not in use, keep it away from
other metal objects such as: paper clips, coins,
keys, nails, screws, or other small metal objects
that can make a connection from one terminal to
another. Shorting the battery terminals together may
cause sparks, burns, or a fire.
Should the tool fail in spite of careful manufacturing and
testing procedures, have the repairs performed by an
authorised customer service location for Bosch electro-
tools.
For inquiries and spare parts ordering, please include
the 10-digit order number on the nameplate of the tool.
After approx. 150 hours of operation, the gearbox is to
be cleaned for the first time and then every 300 hours of
operation. After each cleaning, it should be lubricated
with special gearbox grease.

Press off the marking ring 18 with a thin screwdriver
blade, a knife or similar. Slide the spring ring 19 with
spring ring pliers to the rear onto the housing shell.
The two shell halves of the LED holder 16 that enclose
the LED work area lamp 21 can now be placed in any
desired position. Take care not to damage the cable
of the LED work area lamp and slide it into the cavity
20 intended for it in the housing shell without kinking.
Enclose the LED work area lamp 21 again with the two
housing shells of the LED holder 16. Press the spring
ring 19 and the marking ring 18 back to their initial po-
sitions.
The moving parts of the coupling are to be lubricated
every approx. 100000 screwing actions with a few
drops of SAE 10/SAE 20 motor oil. The sliding and
rolling parts are to be lubricated with Molycote grease.
Check the setting of the coupling after lubricating.
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 centre can perform this
work quickly and reliably.
Dispose of lubricants and cleaning agents in an
environmentally correct manner. Observe legal
regulations.
