capable of withstanding great pressures
integral blow-out valve, preventing any explosive gas release
self-venting filling valve
Catalytic combustion -
flame-free heating system
reaction products are carbon dioxide and water
high efficiency (over 95% gas utilisation)
Patented „Magnetic Thermostat‟ for accurately controlling temperature
Safety cut-out –operates if the temperature exceeds 260ºC (500ºF),cutting
off the gas supply to the combustion chamber.
Exhaust gas manifold for cooling exhaust gas temperature
Integral piezo-electric ignition
Integral hinged tool stand
SAFETY INSTRUCTIONS
Do not touch the nozzle, the exhaust ports, or molten adhesive with
bare skin as they are hot - the operating temperature of the GAS-TEC
500 is approximately 200ºC. Protective gloves should always be worn.
Careless handling can cause skin burns. If molten adhesive comes into
contact with the skin immerse the affected area immediately in plenty of cold
water. Seek medical advice if necessary.
In addition to the safety instructions herein, any statutory regulations, local
fire insurance regulations, or other generally valid “regulations for accident
prevention” must be complied with when using this tool.
 Never use the tool if it is damaged in any way.
 Do not use this tool whilst under the influence of drugs or alcohol.
 Do not use this tool in the vicinity of any heat-sensitive materials, or any
flammable materials, liquids, or gases.
 When refilling, ensure that you switch off the tool before commencing, and
that you keep away from sources of ignition.
 Ensure that the tool is held away from your face and body whilst igniting the
gas.
 Always use the fold-away stand provided (see figure 1 ) when resting the
tool. Do not leave the tool on its side, as molten adhesive may flow back into
the melt chamber, clogging the feed system.
 Do not leave the tool unattended whilst switched on.
 Do not expose to heat above 50°C (120°F), and avoid prolonged exposure to
the sun.
 Do not try to open, puncture, or incinerate the gas tank.

PREPARING THE GUN FOR USE
The Gas-Tec 500 is shipped without gas.
1. First fill the Gas-Tec 500 with butane gas (see figure 1 ). We recommend
the use of Braun, Calibri, Ronson, Rowenta, or other high-quality cigarette
lighter fuel.
When refilling, ensure that you switch off the tool before commencing,
and that you keep away from sources of ignition.
2.Load the tool with a high-performance Tec-Bond®12mm adhesive stick (see
figure 1 ).
3. Switch on the gas by rotating the „gas on/off‟ switch anticlockwise to position
„I‟ (see figure 1 ).
4. Press the ignition button (see figure 1 ) to ignite the gas. Gas ignition may
be confirmed by the sound of the gas flow changing (to a mild „roar‟), or by a
visible glow appearing in the „Ignition View‟ window (see figure 1 ) a few
moments later. You may need to repeat pressing the ignition button to
achieve ignition.
Ensure that the tool is held away from your face and body whilst
igniting the gas.
The glow in the ignition view window will disappear once the tool has
reached temperature (the thermostat valve will close, shutting off the
gas supply). It will only reappear once the tool has cooled sufficiently
for the thermostat gas valve to open.
5. Allow at least 4 minutes for the tool to reach operational temperature
(approx. 195°C/385°F).
Always use the fold-away stand provided (see figure 1 ) when resting
the tool. Do not leave the tool on its side, as molten adhesive may
flow back into the melt chamber, clogging the feed system. Do not
leave the tool unattended whilst switched on.
6. Adhesive may now be extruded through the tool by simply pulling the trigger
(see figure 1 ). Adhesive flow is controlled by regulating the pressure
applied to the trigger, and is stopped by simply releasing it.
SWITCHING THE GUN OFF
When work with the tool has been completed, switch off the gas by rotating
the „gas on/off‟ switch clockwise to position „O‟ (see figure 1 ).
Allow the tool to stand for a few minutes before packing away, as it
may operate one last time (even though the switch is in the ‘off’
position); this is due to the tool consuming any gas retained between
the switch and the thermostat valve.

APPLICATIONS
BOND SEAL ASSEMBLE INSULATE REINFORCE ENCAPSULATE
REPAIR FILL - INSTANTLY
Suitable for use with most materials. Just apply TEC-BOND®hotmelt to one
surface then press parts together and the bond is made. Can be used for
bonding: Wood, Paper, Cardboard, Foam, Chipboard, Hardboard, some
Plastics, Rubber, Glass, thin Metals, Ceramics, Leather, Fabrics and many
more.
The GAS-TEC 500 is simplicity itself. To operate just turn on the gas, press the
ignition switch, and the gun will be ready for use in approximately 5 minutes.
Glue sticks can be fed continuously through the back of the gun. Use only
genuine TEC-BOND®high performance glue sticks.
APPLICATION NOTES
As with all adhesives, performance depends on conditions of use. Suggestions
or recommendations contained herein are for guidance only, since actual
conditions of use are outside the supplier‟s control.
 Ensure that the surfaces to be bonded are dry, free from dust, grease, and
loose particles.
 Apply adhesive to one surface only. Bring the two surfaces together
immediately, quickly making any further adjustments. Hold the joint for 20 - 30
seconds to complete the bond.
 When gluing dissimilar materials, apply the adhesive to the least heat
conductive of the two.
 On materials that are cold to the touch, a better bond can be made by pre-
warming them before applying adhesive.
 Surplus adhesive can be trimmed using a sharp knife once it has cooled.
Should molten adhesive drip onto a smooth or polished surface, allow it to cool
completely before removal.
 Spots or blobs of adhesive are recommended for workpieces having a large
surface area, or which are particularly long.
 Applying the adhesive in wavy lines is recommended for gluing textiles or
similar materials.
 Foam materials, like polystyrene, can be easily bonded to other surfaces.
However the adhesive must be applied to the other surfaces, not to the foam.
 Use only genuine TEC-BOND® adhesive sticks to ensure reliable performance.
TEC-BOND®adhesive sticks are non-toxic and non-flammable.
