HOSE INSTALLATION
7. Take away the Allen key (1) (fig. 8), and replace it with a square key
(1) (fig. 9). Turning this key, the spring fixation (2) (fig. 9) will turn
(the spool will keep static) and the power spring will get tension.
WARNING: Extreme caution. While applying tension to the
!
power spring, it will get strong force. Grab firmly the key and the
hose reel, using heavy leather gloves. If the spool starts to turn
freely, it could cause injuries.
- Never allow the spool to turn freely. If it does, high speeds could be
reached. Hose reel parts could be damaged and you could be injured
if hit by the hose or any other moving part.
- Always grasp firmly, and with enough security, the spool and adjusting
tools while applying tension to the spring. The spring tension can
cause the tools to move violently.
- Attach the hose reel firmly on a flat stable surface during instalation/
maintenance.
8. Apply the pre-tension to the power spring as shown in Table 1, by
means turning the tool in possitive direction, following the indication
stamped on the casing (4) (fig. 8).

CAUTION: Make sure to avoid the power spring to exceed the
!
19 maximum turns. If so, the service life and the spring power
will be decreased.
If you are in doubt about how many pre-tension turns to apply,
first, count the spool turns "N" to fully coil the desired hose.
Then, calculate 19·N = maximum pre-tension turns.
9. After applying the pre-tension turns, without releasing the tool (1)
(fig. 9) and grasping it firmly, introduce the bolts (3) (fig. 9). While
tightening these bolts, pay attention not to release the tool, because
this could cause injure. Once the first bolt is tighten, do not turn
again the tool, this stress could damage the Tensor piece (2) (fig. 9).
10. After tighten the 4 bolts (3) (fig. 9), release the tool (1) (fig. 9). Verify
if the hose reel is coiling properly with the desired force, coiling and
uncoiling several times. If necessary, adjust the spring tension
following the instructions shown in section "Spring load adjustment".
11. Assemble the service lid (1) (fig. 7) using the plastic nuts (2) (fig. 7).
Do not apply too much torque, because you could damage the nuts
thread. No tools required for this operation.
12. Connect the inlet hose to the swivel. Make sure not to apply too much
torque to the swivel, use a flat-wrench if necessary to make counter-force.
1. With the hose reel firmly attached on a surface, uncoil all the hose
and latch the spool in the nearest position. For higher security, use
a tool which avoid the spool to turn freely. If not, it is recommended
to block de spool by introducing an Allen key 7 mm between faces
(1) (fig. 10) inside the brass hexagon (2) (fig. 10), through the
Tensor piece (3) (fig. 10).
