Ratchet mechanism

(Figure No. 4 and 5)
The hose reel is delivered with a ratchet mechanism which retains the hose
in the required out-drawn position. The ratchet will disengage if the hose is
drawn out a little further, and the hose then recoils to the drum.
NOTE! The hose should be held by hand as long as possible during the
recoiling.
The ratchet is factory set for wall mounting of the reel (Figure No. 5/A). When
mounting the reel in ceiling, the ratchet must be moved from one position to
another. (Figure No. 5/B,C).
NOTE! The ratchet must, after it has been mounted, point towards the centre
of the reel.
NOTE! (Figure No. 7)
If the hose is pulled out too far, the ratchet could unfortunately become
permanently locked. It may be released by the following procedure.
1. Take a steady grip in the drum end plate and turn a little in the outdraw
direction until the ratchet is disconnected.
2. Holding the end plate and hose at the same time, slowly release until the
hose has been recoiled.
3. Fit the ratchet in the other mounting position.

Adjustment of spring tension

(Figure No. 8)
The reel has factory set basic spring tension which after mounting the reel
could need an adjustment.
NOTE! Do not tense the spring more than is needed to exactly roll the hose to
its rest position.
