4. Adjust the air pressure level using the
("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 "" indicating that temperature is being adjusted. It will return
H
to "
" (indicating actual temperature) while the temperature is
gradually increasing or decreasing until the set temperature is
reached.
IMPORTANT:
strongly 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 pos-
sibility 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,
panels "10" 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. Turn OFF the Hot Air Gun Function Switch 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 "
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 "
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.
