Start by moving the spindle on its furthest position from the tubular structure.
Lift the hose to the hook - locate where to put the cable tie. Give it enough slack.
Install the cable tie and slide it on the hook.
Repeat the process for the second cable tie. Ensure the hose has enough slack not to restrict the arm's movement.
Cut off the excess of both cable ties.
For the enclosure, make sure the hose passes on top of the tubular structure as shown below. This will prevent any damage to the enclosure or the hose.
