Weka DK08 Betriebsanleitung Seite 18

Use by dry drilling absolutely a powerful dust exhauster which´s filter doesn´t obstruct.
Drilling dry is only possible if the masonry is absolutely dry - risk of obstruction.
Before working dry with the DK09/17 in order to avoid obstruction, take care that the inner side of the
spindle is absolutely dry.
For the rest proceed as explained in 5.3.
5.5 General directions for drilling
Adjust the quantity of water by using the ball valve to such an extent that the loose material gets
completely washed out of the drilled hole.
You do not wash out enough material if mud occurs around the drilled hole.
Use sufficient contact pressure. If it is too low the diamonds tend to polish. This means that the feed
speed becomes less until finally no material is cleared away any more.
In this case the segments are to "sharpen" again by means of a SiC-grindstone.
Take care that the core bit does not vibrate; otherwise the diamonds are detached by force.
By drilling of reinforcements you might have to use greater initial pressure and the next lower gear.
In case the machine gets stuck do not try to loosen it by switching it on and off. Immediately switch off
the machine and loosen the bit by turning an appropriate wrench to the left and right. At the same time,
pull the machine out of the drilled hole carefully.
Take care not to cut a water-pipe or even an electric mains. In case of doubt use a line detector
for searching the drilling area.
6. M A I N T E N A N C E
Always and on principle pull the mains plug before beginning with works of maintenance
or repairs.
Clean the machine after you have finished drilling. Do not forget to clean the core bit thread and grease
it.
Clean the machine with a dry or moist cleaning-rag and not with a jet of water. Keep the ventilation
apertures clean.
Damaged PRCDs, cords and plugs have to be repaired or exchanged exclusively in an authorized repair
station (www.weka-elektrowerkzeuge.de).
6.1 Oil-bath lubrication
After the first 100 hours of using the machine you should replace the gear system´s oil. Get this done in
a specialist´s workshop or demand on the appropriate technical documents for this work.
ATTENTION: If oil comes out of the machine, stop working with it immediately. Leakage of oil does
damage the gear system.
6.2 Carbon brushes
After you have used the machine for about 300 hours you should check the carbon brushes for wear and
replace them if necessary. Like any other work on the motor this must be done by an electrical specialist.
