Service: Installation of ground screw
Preconditions:
-
DMZ329 / DMZ330 must be purchased (upper tube and ground screw)
-
Make sure there are no pipes, tubes, gas pipes, water or power supply in the ground. The
property owner / customer must sign the foundation installation conditions (you will find
the template on the last page of these instructions). By this written confirmation, the
buyer / customer assumes liability and duty of care.
-
There must be free access to the installation area.
1.
Check online where to find the next available Krinner sales partner (go to
https://www.schraubfundamente.de/en/kontakt/regions/ and enter your postal code).
2.
Contact your Krinner sales representative and clarify the installation. Optimally forward
this instruction manual (digital version available) and ask for your individual offer, possibly
a quote with hourly rate and call-out charge.
3.
Your Krinner sales partner must view the terrace and identify the soil class by a test
drilling. The soil class must not exceed class 4, down to 2 m below ground level (length of
the ground screw). This helps to clarify whether the KR20 screwing machine is suitable or
whether a larger machine must be used. This soil analysis is only binding in case of a
homogeneous soil fabric.
4.
This manual illustrates the “5 steps to fasten the ground screw“. As soon as the SZ329 /
SZ330, the ground screw and the MAY parasol has been delivered to the terrace, the
service technician can start with the installation according to step 1, 2 and 3. Mainly tools
needed: Screwing machine KR20, hammer drill, a ø40x800mm rock drill, a Krinner screw-
in attachment F1234567, a 1.2 m ground screw and in case of multiple parasols an optical
level. In order to coordinate this project, it is recommended to have a MAY representative
on site.
Placing the ground screw
1.
Allow sufficient space between parasols or between the wall of the house and the parasol.
Parasols that are located too close together wear sooner.
Parasols may sway slightly. If there is not enough space between them, they
may touch and abrade or scour the canopy fabric at the spoke ends.
Make sure that there is a clearance of 15-20 cm between the parasols (or
between the parasol and the wall of the house).
2.
Bear in mind, we are able to compensate any unevenness of the ground by adjusting the
height of each individual parasol. Extra - length upper tubes are available at 10 cm
gradation and can be adjusted and accommodated on-site.
