PRODUCT SPECIFIC NOTES:
Definition:
Fig. 1: Rope types to be used
Exclusively dynamic single ropes according to EN 892 must be
used. Diameter range 8.9-11.0 mm (see Fig. 1a)
The actual rope diameter may differ by ± 0.2 mm from the rated
diameter indicated by the manufacturer. Use of static ropes is
allowed only for belaying with rope deflection (top roping)
or for lowering or abseiling a person, but not for securing of a
lead climber! The OHM is NOT a belay device! Avoid sagging of
ropes.
Minimum breaking force of OHM: 15 kN (see Fig. 1a)
Weight difference: The unit is suitable for rope parties, in which
the lead climber is min. 10 kg and max. 40 kg heavier than the
person belaying him. Persons weighing less than 40 kg must not
use the device. (see Fig. 1b)
Fig. 2: Preparing the OHM
Using an express sling with a total length of min. 20 cm to max.
30 cm, install the OHM to the first protection point of a securing
line. The correct feed direction of the rope corresponds to the
pictorials on the device and must be checked before every use.
(see Fig. 2)
Fig. 3: Rest position:
The OHM is suspended with no load from the first protection point
(see Fig. 3b)
Activated condition: Upon a fall or during tensile loading, the
OHM is pulled up and ads friction into the breaking process. (see
Fig. 3a)
Fig. 4: Installation:
The OHM is attached to the first protection point of a securing
line. The person belaying must be located at a distance of at least
1 m in each direction outside the fall line of the first intermediate
protection point (similar to the recommendations of DAV and
KleVer). (see Fig. 4a) If the wall is inclined less than 90°, the
lateral distance to the fall line must be at least 1 m, to ensure
OHM is functioning properly. (see Fig. 4b) To secure a top rope
climber, the OHM is likewise installed in the first intermediate
protection point. (see Fig. 4c)
If the belayer is vertically below the hinge point of OHM, the
