SPRING LOAD ADJUSTMENT
If you wish to increase or decrease the power springs 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 and start turning 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. 8), and the 4 nuts (2) (Fig. 8). 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).
4. Assemble the ratchet assembly in place and tight the 2 bolts (1)
(Fig. 8), and the 4 nuts (2) (Fig. 8).
5. Make sure the ratchet assembly works properly.
SWIVEL REPLACEMENT
1. Disconnect the hose of the inlet shaft (1) (Fig. 9).
2. Loosen the set screw in the nut (2) and remove said nut (3) (Fig. 10).
3. Remove the screws (4) and the lateral cover (5) and the spacer tube
(6) (Fig. 10).
4. Remove the gooseneck from the swivel. Use two wrenches in order to
avoid any shaft damage.
5. Remove the swivel (7) (Fig. 10 & 11) and replace it with a new one, or
replace the seals (8) (Fig. 11). Make sure the seals are placed correctly.
6. Grease the interior of the swivel and place it carefully back on the shaft
until it touches the bearing on the spool.
7. Place back the rest of parts in reverse order.
