5. Adjust the hot air gun air temperature using the hot air gun
temperature adjustment buttons ("B2 and B3" from the control
panel). The display for Hot Air Gun Temperature will change
from actual temperature display to set temperature display while
the buttons are adjusted. When set temperature adjustment is
done wait a few seconds for the display B1 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.
6. Reworking task can be started 1 minute after the desired hot air
temperature and airflow level are reached, as also indicated from
display panel "B1" and the airflow gauge.
7. When reworking is complete, return the Hot Air Gun to its holder
and DO NOT immediately turn off the main power switch.
8. Deactivate the Hot Air Gun Activation button "B4" first in order 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 maximum 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.
9. Turn OFF the main power switch.
10. Unplug the device from the main power source.
