Working safely with this machine is
possible only when the operating
and safety information are read
completely and the instructions
contained therein are strictly
followed.
In addition, the Section
Safety
Instructions for Pneumatic Tools
must be observed.
Before using for the first time, ask
for a practical demonstration.
■
Disconnect the air supply.
Disconnect the air supply when the machine is not
in use, before maintenance work and for the
changing of the tools.
Check the direction of rotation setting
before operating the machine!
■
Keep hands away from the rotating tool holder as
well as the tool.
■
Use only flawless insertion tools that are not worn.
Defective insertion tools can cause injuries.
■
Pay attention to firm seating of the insertion tools!
■
Be careful in confined working conditions.
As a result of the reaction torque, injuries can occur
from squeezing or pinching.
■
Be careful when screwing in long screws; danger
of sliding off.
■
Place the machine on the screw/nut only when
switched off.
■
Secure the workpiece.
Use clamping devices or a vice to hold the
workpiece in place. In this manner, it is held more
securely than with your hand and makes possible
the operation of the machine with both hands.
■
Be careful of torque reaction!
For high torque settings and reduced operating
pressure, the clutch no longer disengages.
■
It is recommended that a auxiliary handle always be
used to reduce the danger of injury at high torques.
■
Bosch can assure flawless functioning of the
machine only when original accessories are used.
The supplied air must be free of foreign material and
humidity to protect the machine from damage,
contamination and rust.
The use of a pressurised air maintenance unit is
necessary.
All fittings, connecting lines and hoses must be
dimensioned for the required air pressure and volume.
Avoid restrictions in the air supply resulting from, e.g.,
pinching, kinking or stretching!
In case of doubt, measure the pressure with an
pressure gauge at the air inlet with the machine
switched on.
Maintenance Unit
The maintenance unit ensures fault-free functioning of
pneumatic tools.
It consists of three major components:
–
Filter with water separator
–
Pressure reduction valve with pressure gauge
–
Mist oiler
Lubricant in the mist oiler: Motor oil SAE 10/SAE 20.
Do not use paraffin or diesel oil.
Adjust the mist oiler so that a thin film of oil collects on
the air outlet.
Observe the operating instructions of the maintenance
unit.
The machine operates optimally with a pressure of
6.3 bar (90 psi) measured at the air inlet with the
machine running.
Depending on the type of machine, actuate the
lever
9
or the on-off switch
12
several times before
connecting to the air supply.
Switching On/Off
If the machine does not start, e.g. after not being used
for a longer time, disconnect the air supply and turn
the tool holder
1
by hand. Adhesive forces are
eliminated in this manner.
For an interruption of the air supply or reduced
operating pressure, switch off the machine.
Check the operating pressure and start again
when the pressure returns to normal.
