DO examine the hose, reel swivel and other equipment
for damage (including 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
Reel Swivel frequently. (Refer to the Retracta
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.

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.
