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.
