INSTALLATION
HOSE INSTALLATION
1. To install the hose the first time, make sure the power spring is
relaxed, with no tension, in such a way that the spool does not try
to turn (the ratchet must be unlocked).
2. Connect the new hose to the swivel (2) (fig. 4) making sure the hose
is placed on the plastic piece, and then hold the hose firmly to the
spool using the P-Clip (1). It is not recommended to exert high force
on the swivel, for this reason the hose must remain relaxed between
the P-clip and the swivel, showing a gradual curve.
NOTE: For air/water hose reels, the hose connection to the swivel
should be done grabbing the hose to the swivel barb fitting by means
the worm drive clip.
3. Start to rewind the hose, turning the spool manually until the hose is
completely wound around the spool (the power spring still will be
with no tension). Apply the pre-tension to the power spring by
turning the spool in positively direction as shown in (fig. 5). Do not
apply more pre-tension turns than shown in table 1, the power
spring could be damaged.

4. Pass the hose end through the roller outlet to the desired length,
lock the spool with the ratchet in the nearest position and place the
hose stopper (fig. 6).
5. Fully unwind and rewind the hose to make sure the power spring is
correctly tensioned.
HOSE REPLACEMENT
1. Ensure the reel is firmly attached. Take the hose fully out and let the
spool blocked by the ratchet mechanism.
NOTE: Beware the spool to get loose and start turning freely.
2. Remove the P-clip (1) (fig. 4), and disconnect the hose from the
swivel (2) (fig. 4).
3. Take away the hose from the spool and remove the hose.
4. Connect the new hose to the swivel (2) (fig. 4) making sure the
hose is placed on the plastic piece, and then hold the hose firmly to
the spool using the P-Clip (1). It is not recommended to exert high
force on the swivel, for this reason the hose must remain relaxed
between the P-clip and the swivel, showing a gradual curve.
SPRING LOAD ADJUSTMENT
If you wish to increase or decrease the power spring tension:
1. Pull the hose out till the first ratchet locking position.
2. Remove the hose stopper and pull the hose out in order to unlock
the ratchet.
3. Allow the hose to fully wind into the spool, applying some counter-
force in order to avoid the spool to turn freely.
NOTE: Beware the spool may get loose an start turning freely.

5. Allow the hose to slowly wind into the spool and ensure to finish
with the whole hose inside the reel and the power spring with no
tension (in such a way that the spool does not try to turn).
6. Apply the pre-tension to the power spring as shown in table 1, by
turning the spool in positively direction as shown in (fig. 5). Do not
apply more pre-tension turns than shown in table 1, the power
spring could be damaged.
7. Pass the hose end through the roller outlet to the desired length,
lock the spool with the ratchet in the nearest position and place the
hose stopper (fig. 6).
8. Fully unwind and rewind the hose to make sure the power spring is
correctly tensioned.
4. Turn the spool to increase or decrease the power spring (fig. 5).
NOTE: Do not apply more pre-tension turns than shown in table 1, the
power spring could be damaged.
5. Pass again the hose end through the roller outlet and place the hose
stopper in the desired position.
6. Make sure that the hose fully winds and unwinds properly. If it does
not, repeat the previous steps until it does.
