Reel Operation

WARNING

Do not exceed the lowest pressure rating

of any component in the system.

Heed the Warnings within the manual(s) enclosed
with all welding equipment. For example, bleed all
hoses when not in use for 30 minutes.

Ensure all components are in operable condition.
Replace any suspect parts prior to operation. Per-
sonal injury can occur. 

Hold the delivery hose securely until the reel is
securely latched or fully retracted. Uncontrolled
retraction can result in personal injury.

Latch Lockout

Do not extend the hose from the reel too rapidly. Too 

much velocity can cause the reel to over-run and latch. If 
this occurs, pulling on the hose will not release the latch 
mechanism.

Should 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 the Sheave Assembly securely with gloved hands.

• Gloves should be non-slip.

  3. Turn the Sheave Assembly in the direction just enough 

that allows Pawl (

23

) to be free of tension from the 

ratchet on Power Spring Assembly (

26

). 

• 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.
