Delivery Hose Replacement
Disassembly
1.
Extend the delivery hose completely from the reel.
WARNING
Precautions must be taken to ensure the Sheave
Assembly remains engaged with the Power
Spring’s ratchet. To prevent movement either:
•
Instruct an assistant to grip the Sheave
Assembly securely with non-slip gloved
hands or
•
Install a clamp on the Sheave Assembly
Personal injury can occur.
2.
Remove the dispense nozzle and hose bumper.
3.
Disconnect the delivery hose from union.
4.
Remove Wing Nuts and Washers that secure
U-Bolt to the hose.
5.
Feed hose through the Hose Guide Assembly and
remove the hose.
Assembly
1.
Wind spool flange clockwise-facing swivel-until
spring is tight.
2.
Back off three turns and latch.
3.
Feed the end of the new delivery hose through the
Hose Guide Assembly.
4.
Connect hose fitting to swivel joint (
24
).
Hint:
Orient the hose to allow its natural curve
to match the Sheave. This reduces torque load
on the Power Spring Assembly.
5.
Secure hose to spool using included U-bolts.
IMPORTANT: Allow some slack on the hose
between the U-Bolt and Swivel Joint (
24
).
6.
Install dispense nozzle (with thread sealant) and
hose stop to the delivery hose.
7.
Pressurize the system and check for leaks.
8.
Carefully release the Sheave Assembly and retract
the hose onto the reel.
9.
Check Spring Tension.
Setting Spring Tension
To adjust spring tension, add or remove wraps of hose
from the spool, one wrap at a time until desired tension is
obtained.
When the hose is fully extended from the reel, the power
spring should be a minimum of ½ turn from a fully
wound condition.
Repairs
Extensive repairs should be performed only by an
authorized service center to avoid damage which may
void warranty. Remove all spring tension before
beginning disassembly process.
WARNING
• Failure to remove spring tension before
disassembly can cause irreparable bodily
damage or death.
