WARNING
!
USE EXTREME CAUTION WHEN HANDLING
THE POWER SPRING!
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 (20). Be sure the spring case is lying
flat, and then carefully lift up the cover to expose
the power spring.
WARNING
!
Maintenance
Replacing Power Spring:
1. Be sure the pressure supply has been
relieved.
Follow the pressure relief
procedures below.
2. Disconnect inlet hose. Remove the reel
to work bench and clamp reel base
securely.
3. Remove hose stop and control dispens
ing valve, retract the hose and remove
nesessary wraps until
all power spring
tension has been removed.
4. Remove screws (11, 12 & 16) from base
(40), hub (29) and top tie bar (19).
5. Unclamp the reel form the workbench
and lay it on a flat work surface so the
spring case (21) is facing up.
6. Twist the complete spring case assembly
to the left or right and once the upright
(15) is clear of the base (40) and the top
tie bar (19) lift to remove the assembly.
NOTE:
Be sure that both bolts (24) and
safety cotter pins (20) are still in place on
each side of the case before lifting. (see
figure 12 for placement of cotter pins).
7. Be sure case is lying flat on the work
surface, now remove bolts (24). Next
using extreme caution, remove both
safety cotter pins from sides of case
and lift up on the spring case cover (22)
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 plates (26) properly, replace the
power spring. 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 10)
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 (24)
and spacer (10).
11. Replace spring case cover (23) and
insert cotter pins (20) through sides of
spring case and cover. Tighten case
and cover to upright (15).
