User manual KRESS AS 72 S

[. . . ] Important instructions, which should be read before starting operation, and which we strongly recommend observing: ­ For charging the batteries, only use a charger which is recommended by the manufacturer and never use the recommended charger to charge other electrical equipment. ­ Any machines and batteries that are not being used should be kept separately in a dry place that is high up or locked, out of the reach of children. For safety's sake, a battery charger connected to the mains should also be permanently supervised. Do not place the battery on radiators or expose to strong sun rays for a longer time; temperatures over 50 °C cause damage. [. . . ] The maximum charging time is 4 hours, but if there is already a residual charge available, the charging time is respectively shorter. After a maximum charging time of 8 hours, the battery should be disconnected from the battery charger or removed from the charger adapter. Should charging still not be possible, please send the battery and battery charger to our nearest service centre. Notes for the correct use of the battery: ­ To obtain the maximum service life, do not recharge the battery immediately after a short period of use but, if possible, discharge to the lower capacity limit and then recharge. The resulting excessive current flow leads to quick discharging and increased wear of the battery. ­ An increasingly shorter operating time per recharging of the battery is an indication that the battery is worn out and must be replaced. As a basic rule, return the faulty machine to our next customer service centre (also in the case of defective mains cables)!The rotational direction of the working spindle is set using the rotational direction switch 3. The machine is thereby prevented from being switch on unintentionally and the battery is protected against unintended discharging. In addition, the working spindle is locked when the switch is in this position. This enables a tool or bit to be changed, or the drill chuck to be mounted or dismounted. In the "Lock" position the battery-driven screwdriver can also be used for manual screw-driving jobs that are beyond the capacity of the screwdriver (e. The fully automatic spindle locking makes possible quick and easy changing of the tool in the drill chuck. For soft drill shafts, it may be necessary to retighten after a short time. For reasons of safety, take the battery out of the device for all installation and removal operations!When drilling steel, take care that no swarf enters the ventilation slits of the housing, as these are attracted by the permanently active magnet of the motor and would remain on the motor. If you make heavy use of the equipment for an extended period of time, we recommend returning it together with the charger to our servicing department for a thorough inspection at regular intervals. This prevents high repair costs and extends the service life of your equipment. Inserting the screwdriver bits The working spindle of the cordless screwdriver is fitted with a hexagonal recess. After removing the drill chuck, commercially available screwdriver bits with a hexagon dimension of 6. 3 mm or 1/4" according to DIN 3126 Form C, can be used for facilitating the screwing procedure by inserting directly into the working spindle: ­ Turn rotational direction switch 3 to the "Lock" position. It is advisable to use socket-head screws since their self-centering action ensures safe work. [. . . ] This electro-tool was manufactured with high precision and subjected to rigorous factory quality controls. Therefore, we guarantee the cost-free correction of fabrication or material defects that occur within 24 months of the date of purchase by the end user. We reserve the right to repair defective parts or replace them with new parts. Improper use or handling as well as opening of the machine by unauthorised repair agencies voids the guarantee. [. . . ]
