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.
