TECHNICAL DESCRIPTION

DK22, DK32 and DK34 are diamond core drills which are operated only when fixed in a rig (2) (rigcontrolled).This core drill is only intended for professional use and may only be operated by trained personnel. Proper use extends only to the drilling of rock, concrete masonry and asphalt. By theaddition of water through the diamond drill bit (3) via the ball valve (1a) the drilled material is flushed away and the tool cooled (wet drilling). The drilling tool, the diamond drill bit (3), is a hollow drill (tube) which is fitted with soldered-on or welded-on segments impregnated with diamonds. If necessary, the flushing water is extracted through a water collecting ring (4) by means of anall-purpose suction unit. ATTENTION: Avoid wet drilling upwards (overhead drilling). If it is indispensable use absolutely a perfect, all right and functioning water-collecting ring. 1.1 Scope of delivery

Diamond core drilling machine (1) with ball valve and plug-in nipple (1a), PRCD (GFCI) circuit-breaker (1b) and operating instructions. 1.2 Noise emissions and vibration (EN 50144)

The typicalA-rated sound pressure level is 86 dB(A). The typical A-rated sound level is 99 dB. The typical rated acceleration is 2.5 m/s². 2. PREPARATION

Satisfy yourself that the machine has not been damaged in transit. Check that the nominal voltage is the same as the voltage indicated on the rating plate. 2.1 Electrical connection

According the European standards EN 61029-1 and IEC 1029-2-6, theelectrical connection of diamond core drills with water supply must be operated via a residual current device (RCD, PRCD) and to a properly earthed socket. In accordance with these regulations, the DK22/DK32/DK34 is fitted with an inline protector (PRCD) (1b) mounted in the cord. This contains both, RCD protection and undervoltage tripping. The PRCD must be switched on using the ON key after the power...
