The hydraulic hoses from the power pack to the power cylinder are a critical component
and should be inspected on a regular basis. They should be protected from construction
equipment in the area so they are not inadvertently damaged.
As you are dealing with extremely high pressure hydraulic oil, even a small pinhole in
the hose can result in sever injury. If a pinhole is discovered, replace the hose
immediately. Do not attempt to splice a damaged hose or to substitute a lower grade
hose. Do not utilize any fittings that are a lower grade, as this will create the potential for
an injury. You are risking injury.
Hoses are considered as a consumable item and are therefore not covered under
warranty.
5) Location of the Power Unit
When setting up the power unit, try to ensure that the connections, electric motor, and
electrical panel are away from pooled water and out of exposure to rain. The power unit
should be sheltered from moisture and set up on a flat, horizontal base.
6) Damaged Hoses or Fittings
If one of the power cylinders is out of order (cracked or inner seal damaged) or can’t
be used due to hose damage near the power cylinder, disconnect the power cylinder and
hoses at the distribution block and install a proper and close the oil path hole of oil
distribution block with blind Nut for working with remaining power cylinders as
temporary. The damaged Power cylinder or hose should be repaired immediately to
make it work in normal condition.
7) Supporting the Power Cylinder in Vertical Holes
When splitting rock or concrete on the vertical plane, it is important to ensure that the
power cylinder does not go deeply into the hole to be broken. This can be best
accomplished using a piece of rebar or similar material, and insert the support through
the power cylinder handles, resting the ends on the surface of the material being broken.
8) Maximizing the Power Cylinder Life
In some situations, the drill hole is not deep enough to accommodate the power cylinder
completely. Powering up the cylinder with some of the pistons outside the hole will cause
an uneven flow of oil of the pistons which are not engaged, which will cause undue wear
on the pistons and seals and shorten the life of the pistons and the power cylinder. Where
possible, ensure that the holes are always drilled deep enough to accommodate the entire
power cylinder, to avoid any damage.
9) Straightness of Holes
The straightness of the hole is very important. If the hole is not straight, the power
cylinder should be bent along with the hole, which is the main cause of cracking of
power cylinders and lower productivity.
