Double Post Fuel Hose Reel
CAUTION
Do not overwind the power spring. Too much tension
reduces the life of the spring.
15. Rotate the Sheave Assembly in the required direction.
16. Pass the free end of the hose through the Hose Guide.
17. Install the control valve and the hose stop.
18. Pressurize the system and check for leaks.
19. Check to ensure the tension on the power spring is sufficient
to properly hold the hose stop against the Hose Guide.
20. Repeat steps 12 - 19 until the proper tension is achieved.
Latch Lockout
Reel Over-Run
IMPORTANT: Do not extend the hose from the
reel too rapidly. Too much velocity can cause the
reel to over-run and latch.
Should latch lockout occur, pulling on the hose will not
release the latch mechanism.
With the reel latch in this condition it will be necessary to
have an assistant maintain tension on the hose while the latching
mechanism is manually released.
WARNING
The reel is under maximum spring tension.
Personal injury can occur.
1. Instruct the assistant to grip the hose securely with both
hands to prevent uncontrolled retraction.
2. Grip Sheave Assembly (14) securely with gloved hands.
3. Turn the Sheave Assembly in the direction just enough that
allows Pawl (38) to be free of tension from the ratchet on
Power Spring Assembly (16).
• This direction further increases tension on the power
spring.
4. While maintaining the position of the Sheave assembly with
one hand, move the Pawl away from the ratchet.
• Use a screwdriver or other suitable tool.
5. Instruct the assistant to allow the hose to retract slowly onto
the Sheave Assembly.

Maintenance
Read each step of the instructions carefully. Make sure a
proper understanding is achieved before proceeding.
WARNING
Release all pressure within the system prior to
performing any maintenance procedure.
Disconnect the air supply line to the pump's motor.
Into an appropriate container, operate the control valve
to discharge the remaining pressure within the system..
Delivery Hose Replacement
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 control valve and hose stop.
3. Disconnect the delivery hose from 90 ° Union (1).
4. Remove Wing Nuts (11) and Washers (12) that secure
U-Bolt (13) to the hose.
• Remove the hose.
5. Feed the end of the new delivery hose through Hose Guide
Assembly (27).
6. Connect the delivery hose to the 90 ° Union.
HINT: Orient the hose to allow its natural curve
to match the Sheave. This reduces torque load on
Power Spring Assembly (16).
7. Secure the delivery hose to the Sheave Assembly with
U-Bolt (13), Washers (12) and Wing Nuts (11).
8. Install the control valve (with thread sealant) and hose stop
to the delivery hose.
IMPORTANT: Allow some slack on the hose
between the U-Bolt and the 90 ° Union.
9. Pressurize the system and check for leaks.
10. Carefully release the Sheave Assembly and retract the hose
onto the reel.
11. Check the Spring Tension.
• Please refer to the section entitled Installation for details.
