DESCRIPTION
Stonecracker for cracking rock, concrete and stone. Noiseless and
vibration-free. Can be used indoors and outdoors. Power of up to
130 Mpa (1300 kg/cm 2 ). No permit required to use.
USE
1. Drill:
– Recommended minimum depth: 30 cm (drill about
10% deeper than required bottom).
– Recommended hole spacing CC 15-30 cm.
– Recommended Ø34-45 mm (larger holes --> wider
spacing).
– The expansion force acts at right angles to the drill
hole, so make sure that at least one direction of
expansion is free. This can mean that the holes need to
be drilled with a certain angle.
– Blow the holes free from dust and water.
2. Mix in bucket:
– 1.2-1.3 L cold water + 5 kg powder.
– Mix well (mechanical mixing with mixing rod or
concrete beater) until the aggregate is completely
smooth and without lumps, approx. 30-60s.
3. Fill the holes all the way up.
4. Evacuate the area and wait at least 2 days (the splitting can
take longer at lower temperatures).
5. Clean the equipment.

DRILLING SUGGESTIONS FOR REQUIRED RESULT
Divide the stone.
FIG. 1
Split the stone into smaller pieces.
FIG. 2
Split flat rock.
FIG. 3
Split part of stone in pipeline trench.
FIG. 4
Split top of stone.
FIG. 5
TEMPERATURE
The recommended outside temperature is 10-25°C (use at other
temperatures is not advised as a result of the risk of failure to split
or blowout, which can be dangerous for persons nearby).
WARNING!
Blowout means that the cracking pulp is pressed up from the
drill hole and expands too quickly to crack the rock. This is
because the temperature is too high, or the wrong amount of
water has been added, and can be dangerous in that there is a
risk of the escaping pulp hitting anyone too near the holes.
MAINTENANCE
STORAGE
Store in a dry place out of the reach of children.
