User manual KRESS SBLR 2250

[. . . ] The speed can be controlled by simply "ACCELERATING" using the on/off switch. Ensure that the drill is not allowed to jam for longer than 2­3 seconds. [. . . ] Screwdriving You can fit screwdriver bits directly into the drill chuck. Always disconnect the mains plug before removing and fitting the drill chuck. Only this guarantees that the chuck is not unintentionally unwound from the drill spindle in anticlockwise mode. Should the chuck be undone from the drill spindle for the purpose of replacement, the new chuck must be tightened with a turning moment of at least 30 Nm before the machine is used again. The plane surfaces of the chuck and drill spindle must be cleaned before a new chuck is mounted. When turning anticlockwise, it is possible that the chuck loosens itself from the spindle. For this reason make sure that the chuck sits properly on the spindle. Always make sure that the chosen speed is correct for the purpose for which you are using the machine. High speed drilling in steel and stone will cause premature tool wear. Use tool steel twist drills for soft materials such as wood and plastics; carbide-tipped stone drills for stone and concrete; high speed twist drills for steel and iron. Also make sure that, when using a gear-rim-chuck, the drill chuck key is never fastened to the drill with chains, strings or by similar means. maintenance The machine's motor has life-time lubrication and requires no special maintenance.
