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 5 m.
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 a thin oil, or protected some
other way against corrosion.
Visible grease nipples ar provided for regular lubrication of the gears with a grease gun. Note the
following for grease lubrication: Every 60 hours of operation check striking mechanism, friction
bearings and antifriction bearings; if necessary, grease them. Every 300 hours of operation grease
the gears and antifriction bearings 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
to check the vanes and bearings at regular intervals. Store pneumatic tools in dry rooms only.
Lubricating oils to be used:
Generally SAE 5 W to SAE 10
For gearless impact wrenches and small grinders, only SAE 5 W.
For damp compressed air, oils are to be used that take up water ( without losing the lubricating
effect) and that contain anticorrosive additives. At lower temperatures (especially for work
outside) it may be necessary to use an antifreeze lubricant (e.g. Kilfrost, BP Energol AX 10,
Kompranol N 74).
For saw-chain lubrication on chain saws:
Machine oil with adhesive additive, viscosity c ST 49-55’ (6.5-7.5 E)/ 50°C
