8. GENERAL CARE & MAINTENANCE
ISOLATE THE MACHINE FROM THE POWER SUPPLY BEFORE ANY
CLEANING OR MAINTENANCE IS UNDERTAKEN
To replace Sealing Wire
Cross (running across the machine from front to back).
Release the terminal at the front (M5 pozidrive). Release end of wire
from spring loaded plunger (M3 socket head screw). Secure terminal
end of sealing wire under M5 screw (pozidrive). Fit plain end of wire
into spring loaded plunger, fully compress the spring and secure with
M3 screw plunger. Remove excess sealing wire remaining at the end
of the plunger.
Front (running across the machine from right to left).
Release old wire in the same manner as the cross sealing wire. When
refitting new wire, observe that the front wire goes into a groove
behind and under the cross sealing wire at the junction of the ‘L’.
ON NO ACCOUNT SHOULD THE WIRE BE CLEANED WITH EMERY CLOTH OR
SAND PAPER, DAMAGE TO THE THERMAL/ELECTRICAL INSULATION OF
THE SEALING HEAD WILL RESULT, REQUIRING COSTLY SHUTDOWN FOR
REPAIR.
Sealing Base
The sealing base consists of a heat resisting sponge rubber, mounted
on an aluminium bar, and covered with a self-adhesive P.T.F.E. tape in
the zone of contact with the sealing wire. Should the top protection
strip (10mm wide P.T.F.E. tape) become badly burnt after continual
use, replace the old strip with new to avoid damage to the sponge
rubber.
Seal Initiating Limit Switch
Situated at the front of the machine. This switch is activated by the
action of the sealing head closing and pressing the switch. The switch
is mounted centrally, and may be set in position by slackening the
locking nuts and moving the switch up and down.
Note! The switch should energize the sealing circuit after the sealing
head has closed

2. SETTING UP
Bench mounted machines are free-standing on four stick on feet.
Each machine is fitted with 3 metres of 3-core mains cable which
should be connected to a suitable outlet in accordance with existing
regulations. It is essential that a supply of 240 vac, 5 amp is available.
The control panel is located at the front of the machine on the main
frame.
3. OPERATING PROCEDURE

4. FILM FEED
Centre-folded film of the chosen width and specification is placed on
the rollers at the right hand side of the machine with the open side of
the roll towards the front of the machine.
Note! Centre-folded film may be wound clockwise or anti-clockwise
on its core. The following diagrams show how each of these types of
winding are fed through the machine.
Clockwise Anti-clockwise
rotation at unwind rotation at unwind
After arranging the film in this manner, the film is then parted and split
over and under the dividing plate and draped over the sealing base
of the machine. To prevent film over -running, the FILM BRAKE SCREW
can be adjusted up or down to create pressure on the back roller.
5. SEAL SETTING
Ensure that the mains cable is connected to the electrical supply,
switch machine ON by means of the rectangular switch on the front of
the machine. The neon indicator will light to show the machine has an
electrical supply.
The seal time control can now be set as follows: -
Set SEAL to 3
Run test seal, a buzzer will sound while the sealing wires are being
impulsed. Increase or decrease the SEAL setting until the correct seal
is achieved.
6. OPERATING CYCLE
The machine is now ready to use. Place the product to be wrapped
on top of the dividing plate, and push it under the top layer of film. The
product and film are then moved onto the sealing pack table.
The pack table should be positioned in a suitable slot at approximately
half the depth of the pack.
With the product in this position, lower the sealing head to initiate the
sealing cycle and complete the seal. This should leave the pack
completely enclosed in film. It will be seen that the trailing seal left, is
the seal for the next pack.
7. FAULT FINDING
Fault Mains switch does not illuminate when pressed
Remedy Check there is a mains supply. Check the fuses in the front
panel and mains cable socket.
Fault Mains switch warning light comes on but does not seal.
Remedy Check that the initiating switch is being actuated when the
sealing head closes. Check mains fuse (splatter on fuse backing can
provide sufficient current to illuminate warning light, but not to
operate the machine.
Fault Front sealing wire burns near cross over point of sealing wire.
Remedy Check that cross sealing wire goes under side sealing wire,
and fit a new wire.
