WARNING

Release all pressure within the system prior to

performing any maintenance procedure.

Turn off the power supply.

Operate the hydraulic tool to relieve the remaining pres-

sure within the system.

Maintenance

Read each step of the instructions carefully. Make sure a

proper understanding is achieved before proceeding.

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 hydraulic tool and hose stop.

3. Disconnect the delivery hose from 90 ° Unions (22).

4. Remove Wing Nuts (16) and Washers (15) that secure

U-Bolts (14) to the hose.

• Remove the hose.

5. Feed the end of the new delivery hose through the Hose

Guide Assembly.

6. Connect the delivery hose to the 90 ° Unions.

HINT: Orient the hose to allow its natural curve

to match the Sheave. This reduces torque load on

Power Spring Assembly (26).

7. Secure the delivery hose to the Sheave Assembly with

U-Bolts (14), Washers (15) and Wing Nuts (16).

8. Install the hydraulic tool (with thread sealant) and hose stop

to the delivery hose.

IMPORTANT: Allow some slack on the hose

between the U-Bolt and the 90 ° Unions.

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.
