OPERATING INSTRUCTION General Performance and pull-through force of this machine are designed for the drilling of steel up to a diameter of 15 mm. Free hand drilling and milling is not possible (danger of injury). Therefore the drill and driving machine has always to be centred and protected against rotating. Drilling (look at fig. 1 to 3) - Equip the machine with the required tool (morse taper MK1) - Fasten feed spindle as far as possible - Centre the machine with the peak at an appropriate counter bracket and fix it - Protect motor part with valve from rotating - Connect pneumatic hose (it is recommended to blow out the hose prior to connection, in order to avoid impurities) - Actuate the valve and then start drilling.(the speed can be adjusted by the valve more or less) - Produce steady heading by unscrewing the spindle. - Provide sufficient cooling (cooling medium) for tool and work piece After having finished the drilling procedure Close valve Turn off compressed air and disconnect pneumatic hose Take the machine out of the holder Loosen drilling/ reaming tool by turning-in spindle and take it out of the morse taper seat Clean collet seat Compiled: 30.07.08 216020030_en.doc Page 3 of 12
SAFETY INSTRUCTIONS Wear goggles (chips danger of injury) Wear protective gloves (cuts by sharp-edged work pieces) Wear protective clothing Ensure safe footing Never work under the influence of alcohol or drugs or stronger medication Switch off the machine before laying aside (shut valve) Disconnect machine after finishing the work (avoiding of unintentional starting) Observe the general current and appropriate accident prevention regulations Compiled: 30.07.08 216020030_en.doc Page 4 of 12
WARTUNGS- UND MONTAGEANWEISUNG Our pneumatic motors are designed for an operation pressure of 4-6 bar. Service life and performance of the machines are decisively determined by a) Degree of air purity b) Lubrication and Maintenance at a) Blow the air hose clear before connecting it to the machine. Install dirt and water separators upstream of the machine, if it is not possible to prevent the formation of rust and water condensation in the air distribution lines. zu b) Life time is multiplied through appropriate greasing. Use always acid- and resin-free SAE 5 W to SAE 10 W oil. Thick flowing oil will clog the vanes and affect the start-up and performance of the machine. It is recommended to install service units and an oiler. Compiled: 30.07.08 216020030_en.doc Page 5 of 12
In winter, or when using very moist air, use anti-freeze lubricant, such as "KILFROST", "BP ENERGOL AX 10" or "Kompranol N 74". Observe instructions on the supplementary sheet: Maintenance of Pneumatic Tools Closed ball bearings which are filled with grease may not be washed out. Replace wear parts - in particular the vanes - when necessary. Vanes are considered worn if their width is less than 14 mm. 2 1602 1701050 1050 15,6 mm Installation <18 mm Replacement After ending a working task, flush the machine with thin oil, or protect some other way against corrosion. DISASSEMBLY AND RE-ASSEMBLY Disassembly and reassembly should only be performed with assistance of the sectional drawing. Motor Screw gearbox housing item 26 out of motor housing item 1, and mind the reduction stage. Knock out the motor parts by tapping the motor housing item 1 slightly on a wooden block and dismantle. Disassemble the motor. Check vanes item 8 regarding wear. Valve Screw complete valve out of motor housing item 1, loosen screen carrier item 51, remove ball item 50, screw off connection nut item 42, remove clamp ring item 47, screw out sleeve screw item 49, pull twist sleeve item 45, ring item 46 and pressure spring item 44 from the valve body item 43. Pull out suction slide item 48. Angle drive Screw cover item 41 off the gearbox housing item 26 (mind the sealing ring item 38), screw out sleeve item 32 with feed spindle, pull planetary gear parts like rim of the gear item 16, planetary Compiled: 30.07.08 216020030_en.doc Page 6 of 12
carrier item 17 with bearings, bushings and bevel gear item 24 out of the gearbox housing item 1. Afterwards remove drill sleeve item 39 with bearings, rings and bevel gear wheel item 35. Re-assembly Basically the re-assembly is done in the reverse order than the disassembly. The axial play between rotor item 7 and the end plates item 3 and 9 should be 0.04 mm per side. This means that the cylinder bushing item 5 is approx. 0.08 mm longer than the rotor item 7. Chamfered edge Before putting in the new vanes item 8, the rotor slots have to be cleaned from oil and resin residues, the new vanes have to be put easily into the slots. Install the cylinder bushing item 5 correctly. Mind the correct setting of the indenting infeed for the angle drive. Use low-viscosity grease for the gear (e. g. Calypsol D 6024). Check the functioning after the complete assembly. Mostly a check of the given free speed and air consumption is sufficient. (see technical specification). Only use original spare parts for repairs!
