Personal injury can occur.

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.
