2. Do not pressure the AC power cord. Be sure the work area is well ventilated.   

3. Do not bump, hit, pour water/liquids or otherwise subject the heating surface to 

physical shock. This may damage the heater.   

4. To isolate the equipment from the mains before commencing repairs or making any 

maintenance to avoid electric shock. This may result in Death or serious injury.   

5. Do not expose the unit to moisture nor use the unit with wet hands.   

6. Turn the power switch off and remove the AC power cord by pulling the plug (not 

the cable) when the unit will remain unused for a longer period of time.   

7. Do not modify the unit. 

 
   

           

Warning  

 

To last the life of the heating element, not recommend continuously using at 
low air flow and high temperature.

 Let the heating element be cooler after using 

a maximum 20 minutes. Ensure that it is placed back on its cooling stand to cool 
down between rework operations. Also, do not switch the hand tool on while it is in 
the cooling stand. 

Fail to comply with the instructions may result in damage to 

the hand tool. 

 

 

Do not aim the hot air at your eyes. 

Do not allow the hot air from the hand tool to 

aim the eyes as serious eye damage may occur.   

 

The hot air pencil can produce a lot of heat.

 Do not allow the heater and the 

nozzle to contact exposed skin as burning may occur. To eliminate the possibility 
of burns, allow time for the equipment to cool before commencing maintenance.   

 

Death or serious injury may result from electric shock. 

It is therefore essential 

to isolate the equipment from the mains before commencing repairs.   

 

  Keep the hot air away from the body, clothes and flammable material when in 

operation. 

The nozzle metal is in a high temperature status, do not touch the 

nozzle! Always replace the hand tool to its original holder when not being use. The 
nozzle and the heating element are still remaining hot after being switched off. 
Ensure that you do not touch them. 

 

 

Do not block the air outlet in full area of the nozzle, or it may cause the heat 
reflection and damage the heating element. 

 

● 

Do not leave when the machine is on operating: 

Stare at the nozzle when the 

rework station is on operating, so as not to burn your body or other objects. Turn 
off the machine and unplug the power cord when you are leaving and put the hot 
air handle to the holder in one side of the machine. The nozzle is still remaining hot 
after being switch off on some time. Ensure that you do not touch the nozzle.
