Horizontal / vertical brake
This section describes the function of the horizontal / vertical brake of the
Dynamic arm
support O540
.
The horizontal/vertical (H / V) brake makes it possible to lock the vertical and horizontal
movements. When applied, only rotational movement around the main axle is available.
The H / V brake is activated by pressing the
button once. After pressing this button,
immediately (within 2 seconds) move the arm a bit in any direction to engage the brake
mechanism. You will know the H/V brake is engaged when you hear a click. It will then be
impossible to move the arm.
To disengage the H / V brake, hold the
button down for 2 seconds.
If for some reason the H/V lock isn’t engaged within 2 seconds, the H/V lock will deactivate. You
will need to push the
button again to reactivate.
The H / V brake is designed to hold a maximum force of 4.5 kg. If a larger force is applied,
the H / V brake will disengage automatically. This is a safety feature to prevent you from injuring
your arm when running into an obstacle, for example, a door frame, while driving the wheelchair.
Once the H / V brake has been disengaged in this matter, it is necessary to hold the button down
for 2 seconds first, before being able to engage it again.
When driving the wheelchair, ensure that the arm is in the brace and the H / V brake
activated to avoid unintended arm movement.
