4. Adjust the air flow level using the airflow adjustment knob ("A2"
from the control panel).
5. Adjust the hot air gun air temperature using the hot air gun
temperature adjustment knob ("A3" from the control panel). The
display for Hot Air Gun Temperature will change from actual
temperature display to set temperature display while the knob is
being adjusted. When set temperature adjustment is done wait a
few seconds for the display A1 to return to displaying the actual
temperature.
IMPORTANT:
advised to initially increase the airflow level in order to manage
the system temperature. This is to protect the heating element
inside the handle from excessive heat and avoid the possibility of
subjecting adjacent components to thermal shock.
7. Reworking task can be started 1 minute after the desired hot air
temperature and airflow level are reached, as also indicated from
display panel "A1" .
8. When reworking is complete, return the Hot Air Gun to its holder
and DO NOT immediately turn off the main power switch.
9. Deactivate the Hot Air Gun by turning the Hot Air Gun set
temperature knob counterclockwise until a click is heard to activate
the auto-cooling process. The system will start to blow air (at room
temperature) at a fast rate to reduce heat from the hot air gun and
bring down the temperature to a reasonable safe level of 90°C.
During this time, the display for hot air gun temperature will also
alternate from "Off" to actual temperature display. Likewise, the air
pressure level is at its highest reading as indicated from the air flow
gauge. Once the temperature drops to approximately 90°C the
system will halt and display "OFF" on the panel. It is now safe to
switch off the main power switch.
10. Turn OFF the main power switch and unplug the device from the
main power source.
