which enables the reel to be mounted in any position.

Please read and retain this instruction manual to
assist you in the operation and maintenance of this
quality product.

INTRODUCTION

The maximum weight of hose end tools is 2kg (4lb).

The maximum installation height is 4.5 meters (15ft)
above the ground.

DO NOT exceed the maximum working pressure stated
on the product label.

2

DO examine the hose, reel swivel and other equipment
for damage (includ in g leaks) should a “Flashback”
occur. Replacement of swivel seals is recommended.
The use of “Flashback” check valves to reduce the risk of
backflow and “Flashback” is also recommended.

DO use only Retracta replacement swivel components
and seals as supplied by Macnaught. Obtain replacemant
parts from your local Authorised Macnaught Service
Centre or from Macnaught.

DO NOT allow grease and oil to come into contact with
any Oxy-Acetylene equipment, components or hose.
These materials ignite easily and burn violently in the
presence of Oxygen.

DO NOT use pipe fitting compounds or thread lubricants
in making connections.

DO NOT direct the gas flame at the hose or hose reel.

DO NOT exceed the recommended maximum Acetylene

draw off rate from the cylinder and only operate when the
cylinder is upright. Liquid acetone solvent contained in
the cylinder can escape and damage the hose, hose reel
seals and other equipment.

DO NOT work with damaged or faulty equipment or hoses.

INSTALLATION

1) Attach the carry handle to the reel casing above the reel
hose mouth, using the screws provided.

2) The reel can only be mounted in one of the following
positions shown. (Refer Fig 1, 2, 3, 4 )

Fig.1 Wall / BU100 Fig.2 Overhead / BU100

If you choose the most popular positions (1) and (2) you
should use the standard (BU100) bracket. If using
position (3) and (4) you will need the optional
bracket (BB100).

Make all connections dry. DO NOT use pipe fitting
compounds, thread lubricants, oil or grease. Tighten hose
connections with a spanner. Oxygen hoses use only right
hand threaded connections. Note Acetylene hoses use
left hand threaded connections.

CAUTION

Test the system and all connections for leaks prior to
use. Re-test the system frequently (once per month
approx) and on each change of gas cylinder or after
maintenance.

Leak test all connections and hose reel swivels prior
to initial use (refer “Gas Leak Test Procedure”) and
repeat at frequent intervals. It is recommended that
leak tests on all equipment be carried out at least
monthly and on the replacement of cylinders and after
maintenance or replacement of any equipment,
component part or hose.

For O-Ring seal lubrication use only ‘Tranz’ 1434 or an
equivalent inert lubricant when required. DO NOT allow
oil or grease to come in contact with the swivel or
Oxy-Fuel gas equipment.

SAFETY PRECAUTIONS

ONLY use this Retracta reel for the Oxy Acetylene gas

combination.

DO locate equipment in well ventilated areas.

DO run leak tests on your total system including the Hose

Re el Sw ivel freq uent ly. ( R efe r to t h e Re t rac ta
Operating and Service Instructions).

DO repair or replace equipment and hoses immediately
any gas leak is detected. Leaking Oxygen or Acetylene
can cause serious fire and personal injury.

Up to 6ft above ground Up to 15ft above ground

Fig.3 Floor/Bench/BB100 Fig.4 High Wall/BB100

Between 1.8m (6ft) and

4.5m (15ft) above ground

3) Fix mounting bracket in required location and position
reel onto bracket. (Brackets can be padlocked for
additional security). Oxy Acetylene reels should only
be used in well ventilated areas.

4) Connect supply hose to reel inlet allowing sufficient
space for reel to swivel 180° on bracket. Swivel
rotation can be avoided (in the overhead position only)
by adding the locking bracket (RB9) supplied.

POSITIVE LATCH OPERATION

Pull out the hose to the required length.

Note: A clicking noise can be heard every half revolution
of the drum.

To latch the reel, allow the reel to slowly retract after
hearing the 1st, 2nd or 3rd click.

To unlatch the reel, slowly pull out the hose until the
clicking noise stops, then let the hose slowly retract until
the hose stopper rests against the reel mouth.

CAUTION

To prevent injury or damage occurring, do not let go of
the hose during rewinding.

3) Rem ove the inl e t side plat e (R efe r Re m ova l/
Replacement Inlet Connection Side Plate).

4) Re mov e circl ip (5) fro m e nd o f s wive l s haft
assembly (1) and slide the inlet shaft from the swivel
body (4).

5) Carefully remove the existing O-Rings by lifting O-Rings
out from grooves using a small screwdriver. With
o-rings extended, cut through the O-Ring onto the
screwdriver face. Be careful you do not score o-ring
grooves.

Do not damage or score inlet shaft surface when
removing or cutting o-ring.

CAUTION

5) Before fitting the new o-rings ensure that both the inlet
shaft and swivel are thoroughly wiped clean. Apply
‘Tranz’ 1434 lubricant (supplied in kit) or equivalent to
the o’ring grooves of the inlet shaft.

6) Slide the o-ring applicator sleeve (supplied in kit) over
the inlet shaft to expose only the furthermost o-ring
groove. Put the first o-ring onto the sleeve and slide up
to the exposed groove. Withdraw the sleeve, stopping
at each groove, and fit the o’rings one at a time
following the same procedure.

SWIVEL RE-ASSEMBLY

7) Slide the inlet shaft back into the swivel body and
replace the circlip. Note that if the circlip groove is not
exposed after fitting, the swivel body is back to front.

GAS LEAK TEST PROCEDURE

Test Oxygen /Acetylene hose lines seperately. Ensure
that all connections from the cylinder through to the torch
are tight.

1) Close both torch valves.

2) Open the Oxygen cylinder valve and adjust the delivery
pressure to 25psi or more.

3) Close the Oxygen valve and observe the delivery
pres sure gaug e. If a drop in pres sur e occ urs,
re-pressure the hose and test all the connections
includi ng the ho se, swiv el and sw ive l bod y by
brushing with warm soapy water solution looking for
the presence of any bubbles.

4) Open the Oxygen valve at the torch and re-close to vent
the Oxygen line. Repeat steps 1, 2 and 3 with the
Acetylene, with the delivery pressure set at 10 psi. Vent
the Acetylene line.

5) Replace or repair any faulty items immediately and
repeat ‘Leak test’ procedure.
