Carbon Brushes - Carat A-2012 Manual

Carbon brushes

Make sure to have carbon brushes inspected every 12 months and replaced if necessary by a certified expert.
Drilling with water cooling – Water connection
The drilling machine is equipped with a water tap, which includes a 'Gardena' connection. Make sure that the core drill is
sufficiently cooled and that the slurry is properly discharged. The maximum permitted water pressure is 3 bars. Always use
clean water to enlarge the life span of the internal water seals. In case of leakage, the drilling machine has to be checked
IMMEDIATELY by a certified mechanical expert.
Dry drilling - Dust Extraction
For dry drilling only use designated drill bits with 5/4"UNC (F) connection.
Dry drilling is only possible in masonry, brick/block and sandstone.
Dust released during dry drilling is dangerous to your health. Therefore a dust extraction system specially intended for this
purpose must be used, and if necessary, a dust mask worn.
The use of a dust extraction system is also required to optimize the life time of the diamond drill bit.
To prevent clogging of the dust extraction system it is essential that the materials which are being drilled are completely dry.
Information about dust extraction systems is available at your diamond tools supplier.
Operating instructions
If drilling is done by hand, initially the drill should never be applied perpendicular to the material (the drill may start
'spinning'). Spinning is prevented by drilling the first centimeter / 0,5 inch at an angle of 30 degrees. Then the drill can be
slowly brought to the desired position. In order to centre without problems, it is advised to use a pilot drill. Once the pilot drill
is removed, the drill can be placed in the pre-drilled hole.

Tips
•
Diamond drills which are not precisely circular cause extra burden to the bearings and the cogs.

Drill carefully and sensitively. Always avoid overloading.
•
Do not lift/move drill machine by the cable
•
If the switches, cable, plug or machine case is damaged, switch off the machine immediately and have it repaired by a
certified expert.
•
Switch on the machine only if the diamond drill can turn freely.
•
When changing the diamond drill, always use 2 spanners . Never use a hammer as this may damage the cogs.
