OPERATING GUIDELINES
6. You may start reworking as soon as the desired air temperature and
air pressure levels are reached.
7. . When reworking is complete, place the Hot Air Gun back to its
holder.
8. Deactivate the HOT AIR GUN function switch (15). The system will
immediately start the auto­cooling process.
Note: During this process, the system will try to release excess heat by
blowing air (at room temperature) until it reaches a safe temperature
value of 85°C before completely switching OFF.
Wait for the auto­cooling process to finish before switching OFF the
9.
main power switch (9). If the display panel shows "OFF" on each
line, then it is now safe to do so.
10. Unplug the device from the main power source.
IMPORTANT: Remember to set airflow level first before setting the
temperature so that it would not damage the heating element, causing it to be
burnt out prematurely. This would help lengthen the usage life span of
main unit and the heating element.
IMPORTANT: Airflow level should be set accordingly, working with low
airflow and high temperature often causes heating element to get easily burnt.

Auto­cool off function
1. When reworking is complete, return the Hot Air Gun to its holder
and DO NOT immediately unplug the device from the main power
source.
2. Deactivate the HOT AIR GUN activation switch first in order to
activate the auto­cooling process. The system will start to blow air
(at room temperature) at maximum rate to reduce heat from the
hot air gun and bring the temperature down to a safe level of 90°C.
During this time, the prefix of hot air gun temperature display will
also change from "H" to "C" while temperature is gradually
decreasing. The air pressure level, likewise, will be at its highest
reading as indicated from the display panel. Once the temperature
drops to approximately 90°C the hot air gun will automatically stop
and display "OFF" on the panel. It is now safe to unplug the device
from the main power source if the system reached this stage.
