POWER SPRING REPLACEMENT
1. Ensure to disconnect the air to the pump and open dispensing valve
until pressure is relieved.
2. Disconnect the inlet hose. Remove the reel to work bench and clamp
it securely.
3. Take the hose fully out and let the spool blocked by the ratchet
mechanism. Remove the P-Clip (1) (fig. 4), and disconnect the hose
from the swivel (2) (fig. 4).
NOTE: Beware the spool may get loose an start turning freely.
4. Wearing heavy leather gloves, firmly grab the outside edge of the
spool with both hands. Unlatch the spool and let it rotate slowly
through your hands until the spool stops. When the spool stops, the
spring tension will be released.

(Fig. 8) and loosening the bolts (3) (fig. 8).
6. Remove the upper arm (9) (fig.10) loosening the bolt (7) (fig. 10).
The spool will be disconnected from the frame. Next, loosen the
bolts (8) (fig. 10) and remove the upper arm.
7. With the spool lying flat, remove the circlip (12) (fig. 11) from the
shaft. Next, loosen the bolts (13). Carefully lift up the power spring
cover (14) which will come out with the bearing, all together. Take
apart the silencer disc (15), and finally disassemble the power
spring (16). Be careful to avoid remove the spring fixation (19)
which could be slightly held to the power spring.
WARNING: Extreme caution when handling the power spring.

!
from the case with enough force to cause serious bodily injury.
Be sure the spool is lying flat, and then carefully lift up the cover
to expose the power spring.
8. Protect your hands with heavy Leather Gloves. Before removing
the power spring, assure it with clamps, helping yourself with
locking type pliers to compress and hold several rows of the power
spring together (fig. 12). Then remove carefully the power spring.
9. Apply a light coat of grease inside the spring case and cover.
Carefully install the new power spring . Be sure, the power spring
hooks are aligned with the spool (20) (fig. 11) and spring fixation
(19) (fig. 14) hooks.
10. Once the power spring is in the case, assemble the silencer disc
(15) (fig. 11) and the lid (14) (fig. 11).
11. Be sure the cover is aligned with the adjacent piece (the slots must
be aligned). Then, fasten the lid with the bolts (13) (fig. 11).
12. After placing the lid, assemble the circlip (12) (fig. 11) and then,
place the spool assembly on the hose reel frame.
13. Place back the remaining parts in reverse order.
14. Once the hose reel is assembled, it is necessary to make the spring
load adjustment and the hose installation. To do this, follow the
