Operation
Extension bolt fixation: Drill a hole by impact drill in the set position and screw the extension
bolt. Always make sure it is tight and fix the diamond drill machine on it. Adjust the four regu -
lating screws to keep the drill machine from swinging.
Support rod fixation: Determine the drilling location. Fix the supporting rod by adjusting the
length of the push rod and also adjust the fastening screws. Ensure that the drilling rig sub -
structure is at full contact. If you drill vertically do not swing.
Fix the drill bit and connect it to the power and water supply. Move the adjusting tools as
needed and switch on the drill when it is at no load. Check the drill bit and the sound and open
the water tap, if everything is fine. The machine can start to drill when the water flows from the
drill bit.
Take it slow at first. When the drill bit cuts in the wall you can change to normal speed. Slow
down the machine if it runs into steel.
The drill machine is equipped with mechanical and electronic protection. If the engine is run -
ning while the drill bit is not moving it means that the drill bit needs to be sharpened or the
feeding speed is too fast. In that case please pull out the drill and then re-feed it. If the engine
shortly stops while drilling, switch it on again and slow down the feed speed.
After a certain period of time the abrasion of the friction plate may cause slip. They might need
to be realigned. This may only be done by a qualified technician.
Cleaning and maintenance
Clean the machine with a dry or moist cleaning-rag and not with a stream of water. Make sure
the water does not get into the engine and the switch box. Keep the ventilation apertures
clean and do not forget to clean the core bit thread. Also grease it and check all screws.
Tighten them if necessary.
Have your tool only repaired by qualified technician and only with original spare parts. Other
parts might cause damage to a person or the machine.
Carbon brush
After you have used the machine for about 300 hours, you should check the wear of the carbon
brushes and replace them if necessary. Like any other work on the engine this must only be done by
an authorized technician.
