Maintenance
Replacing Power Spring:
1. Be sure the pressure supply has been
relieved when.
Follow the pressure relieve
procedures below.
7. Be sure case is laying flat on the work
surface, now remove bolts (23). Then using
extreme caution, remove both safety cotter
pins (17) from sides of case and lift up on the
spring case cover (5) to expose the power
spring.
8.
Carefully Inspect the Power Spring
. If either
end of the power spring is worn or damaged
and will not engage the center clutch plates
(28) properly, replace the power spring.
2. Disconnect inlet hose. Remove the reel to
work bench and clamp reel base securely.
3. Remove hose stop and control dispensing
valve, retract the hose and remove
necessary wraps until
all power spring
tension has been removed
.
4. Remove screws (12) from base (24), hub (4)
and top tie bar (39).
5. Unclamp the reel from the workbench and
lay it on a flat work surface so the spring
case assembly is facing up.
6. Twist the complete spring case assembly
to the left or right, and once the upright (29)
is clear of the base (24) and the top tie bar
(39) lift to remove the assembly.
NOTE:
Be sure that both bolts (23) and
safety cotter pins (17) are still in place on
each side of the case before lifting. (See
figure 7 for placement of cotter pins)
9. Apply a light coat of grease inside the spring
case and cover.
10. Install the new power spring, making sure
that it is laid into the spring case
counter-
clockwise
and that the outside end loop
is around spring case bolt (23) and spacer
(2).
11. Replace spring case cover (5) and insert
cotter pins (17) through sides of spring case
and cover. Tighten case and cover to upright
(29).
12. Twist the complete spring case assembly to
the left or right, making sure that the power
spring is centered and has engaged the
spring center clutch plates (28).
13. Align upright assembly (29) with base (24)
and tip tie bar (39). Place bolts (12) back
through the base and top tie bar and tighten
to 100 - 110 inch pounds. Inspect complete
reel for proper function and adjust power
spring as needed by adding one to two loops
of hose at a time to increase power spring
tension.
Pressure Relief Procedure:
Follow this procedure before maintaining and/or
repairing your Premium Hose Reel and/or any
part of system.
1) Disconnect the air to the pump.
2) Point dispensing valve away from
yourself and others.
3) Open dispensing valve until
pressure is relieved.
WARNING
!
The spring is ALWAYS under great tension and
could be propelled from the case with enough
force to cause serious bodily injury. To reduce the
risk of serious bodily injury, use extreme caution
when removing the top cover (5). Be sure the
spring case if lying flat, and then carefully lift up
the cover to expose the power spring.
CAUTION
USE EXTREME CARE WHEN
HANDLING THE POWER SPRING!
!
WARNING:
If the power spring has
become uncoiled inside the spring case, the
“keeper” has failed. It is strongly advised
that you replace the complete spring case
assembly. The “keeper” is a metal band that
is placed around the power spring to keep it
from uncoiling when removed from the case.
If you attempt to remove the power spring
when this condition has occurred the spring
will uncoil quickly and can cause serious
bodily injury. (See figure 5)
