MAINTENANCE
6. Apply the pre-tension to the power spring by turning the spool the number of turns indicated below, depending on the power spring version
and the hose length (Fig. 5):
HOSE LENGTH
50' (15 m)
65-75' (20 - 25 m)
100' (30 m)
Do not apply more tension than stated, as 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.
8. Fully unwind and rewind the hose to make sure the power spring is correctly tensioned.
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.
LATCH REPLACEMENT
1. With the hose fully wound on the spool and the hose stopper touching the rollers, turn the spool enought to be able to reach the ratchet assembly.
Make sure to avoid the spool to turn freely, blocking it safely.
2. Loosen the 2 bolts (1) (Fig. 6), and the 4 nuts (2) (Fig. 6). Remove the ratchet assembly.
3. Clean the components, or replace the ratchet assembly with a new one. In the case of
unscrewing the ratchet shaft (3) (Fig. 6), be sure to clean the thread and apply
medium-strength threadlocker before screwing it back into the plate (4) (Fig. 6).
4. Assemble the ratchet assembly in place and tight the 2 bolts (1) (Fig. 6).
and the 4 nuts (2) (Fig. 6).
5. Make sure the ratchet assembly works properly.
SWIVEL REPLACEMENT
1. Disconnect the hoses of the inlet shaft (1) and the swivel joint (2) (Fig. 7). On the swivel, use two wrenches (Fig. 4) in
order to avoid any shaft damage.
2. Loosen the set screw in the nut (3) and remove said nut.
