To drill the holes, use the triangle plate
as a template (1 pc) for positioning the foundation bolts.
-
Mark the drilling depth on the drill bit with tape: 200 mm (7.87 in) (with a tolerance
of 5 mm / 0.20 in).
The hole diameter is 20 mm
(0.79 in).
-
Place the template on the concrete foundation. Check the correct
position and orientation of the template depending on your location.
-
To make sure the template does not move, hold the template in place with your
feet.
-
Aim the drill bit through one of the holes in the template and drill a hole that is a
couple of centimeters deep.
-
To avoid getting the drill bit stuck in the hole, lift the drill bit every once in a
while when drilling to remove excess dust.
-
When the first hole is ready, place a foundation bolt in the hole through the template.
This bolt locks one corner of the template in place.
-
Drill a second hole, and place a foundation bolt in the hole through the
template.
-
Drill the third hole, and remove the template.
-
Clean dust from the holes with a brush and compressed air or an air pump.
-
Continue drilling the holes until you reach the tape mark in the drill bit. Clean dust
from the holes using a brush and compressed air or an air pump.
-
To check that the holes are of the same depth, put the foundation bolts into the holes.
Use a spirit level to make sure the bolts are level.
-
For the guy wire foundations for DKP204, drill one hole to each foundation.
| Make sure that 80 mm (3.15 in) of the
foundation bolts is above the surface of the concrete foundation. |

Clean dust from the holes with a brush and compressed air or an air pump.
