Bench Test

While facing the ratchet on the power spring

Assembly, turn the reel in a counterclockwise direction

and allow the ratchet to latch the Pawl.

If the reel does not tension or latch properly, refer to

the Troubleshooting Chart.

Installation

On the Bench

IMPORTANT: Clean the delivery hose

before attachment to the reel.

1. Blow any foreign particles from both lines of the

delivery hose.

• Make sure the hose is clean and dry.

2. Feed the end of the acetylene/oxygen delivery hose

through the opening in Sheave Assembly (16).

3. Screw the oxygen hose end (with right-hand threads)

into Connector (7).

4. Screw the acetylene hose end (with left-hand threads)

into Connector (6) [with notches].

5. Attach the delivery hose to the Sheave Assembly with

U-Bolt (15), Washers (13) and Wing Nuts (14).

• Tighten the Wing Nuts securely.

6. Rotate the Sheave Assembly to wrap the hose onto the

reel.

• The clicking sound is the power spring bypassing the

cam on the Spring Arbor.

7. Screw the acetylene connecting hose [with Teflon

tape] securely into Swivel Shaft (1).

8. Screw the oxygen connecting hose [with Teflon tape]

securely into Shaft and Flange Assembly (41).

Mount the Reel

IMPORTANT: Should the reel mount to a

ceiling, it is mandatory that the reel be

installed at a height no greater than 20 '

(6.1 m) from the floor. Should the existing

ceiling height be greater, mount the reel to a

suspension bracket.

Severe-Duty Welding Hose Reel

9. Mount the reel assembly with the appropriate

hardware.

NOTE: Make sure the connecting hoses do

not chafe on the reel.

10. Install the torch to the delivery hose.

• Make sure the connections are secure.

11. Install and secure the hose stop to the desired position.

Purge the Delivery Hose

WARNING

Purge the delivery hose in a well ventilated

area.

Personal injury can occur due to explosion.

IMPORTANT: Purge each line of the deliv-

ery hose individually.

12. Turn on the regulator at the acetylene tank and remove

all the air within the line.

13. Repeat the process for the oxygen line.

Check for Leaks

14. Apply a soap solution to each connection to ensure no

leakage occurs.

Setting Spring Tension

CAUTION

Do not overwind the power spring. Too much ten-

sion reduces the life of the spring.

To adjust tension on the power spring:

15. Add / remove one coil of hose to / from the Sheave

Assembly.

IMPORTANT: Add or remove hose coils to

provide the amount of spring tension that

gently holds the hose stop against the hose

guide. When the hose is fully extended from

the reel, the power spring should be a mini-

mum of 1/2 turn from a fully wound condition.

16. Repeat step 15 until the proper tension is achieved.
