MAINTENANCE OF PNEUMATIC TOOLS
Only proper maintenance can ensure constant performance, reduction in wear and thus, a
decrease in operating costs and an increase in service life.
Our pneumatic tools are equipped for an operating pressure of 6 bar. A regulator setting for
an operating pressure of 4 bar is possible as well as expedient for grinding machines with a built-
in regulator, so as to take full advantage of the speed prescribed for the corresponding grinding
wheels.
Pneumatic tools should not run empty, because this results in heat and higher wear. The
compressed air should be clean and dry. This is guaranteed by a proper pneumatic system. Blow
through the pneumatic hose before connecting it. For the economical use of pneumatic tools, the
prescribed air quantities are necessary, i.e., the line, armatures and hoses must have the required
cross sections so that the flow pressure remains constant. Proper lubrication is a must; for this
reason, our pneumatic tools usually have built-in oilers, which are located between the inlet valve
and the motor, and which function in any position. In smaller and lighter hand tools, these oilers
must often be left out, because the machines would then be too heavy and not easy to manage.
In such cases, lubrication must be carried out by service units or by manual hose oilers. We
recommend service units for permanently installed workplaces (see accessories list). However,
where longer hose lines are necessary, line oilers built into the hose lines are more effective. The
distance between the tool and oiler should not be more than 5m.
Most of pneumatic tools have located at the connection a lined-up screen, which is to be
regularly checked and cleaned.
After ending a working task, the machines are to be flushed with thin oil, or protected some
other way against corrosion.
Visible grease nipples are provided for regular lubrication of the gears with a grease gun. Note
the following for grease lubrication: Every 60 hours of operation check striking mechanismus,
friction bearing and antifriction bearing; If necessary, grease them. Every 300 hours of operating
grease the gears and antifriction bearing anew. In the case of impact wrenches, use a grease gun to
grease the anvil guide before beginning daily work or every 6 to 8 hours. All inner parts must be
lubricated before storing for longer periods of time in order to prevent rusting. It is recommended
checking the vans and bearings at regular intervals. Store pneumatic tools in dry rooms only.
Lubricating oils
to be used: Generally SAE 5 W to SAE 10
