4. Adjust the air flow level using the AIR PRESSURE ADJUSTMENT
BUTTONS ("3" from the control panel).
5. Adjust the hot air gun air temperature using the HOT AIR GUN
TEMPERATURE ADJUSTMENT BUTTONS ("2" from the control
panel). The prefix of the display for Hot Air Gun Temperature will
change from "H" to "h" indicating that air temperature is being
adjusted. It will return to "H" (indicating actual temperature) while
the temperature is gradually increasing or decreasing until the
desired temperature is reached.
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 panels "11" and "12", respectively.
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 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 prefix of the display for hot air gun
temperature will also change from "H" to "C" while temperature is
gradually decreasing. Likewise, the air pressure level is at its highest
reading as indicated from the display panel. 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.
