b) The lubrication conditions and maintenance.
See "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 .
