Why when I turn on the tool the motor is running but I am not getting any heat from the heat gun?
The most likely problem is the heating element has burned out or the batteries are low. Check the battery gas gauge and if it is low then charge the batteries and check the heat gun again, if you are not getting any heat after that then the heating element is most likely burned out. Remove the heating element according to the service manual instructions and check the element for continuity and replace the element with a new one according to the service manual.

Why does the heat gun not run after I just installed fully charged batteries?
The batteries have a built in overheating protection system. The batteries must be at room temperature in order to work properly, otherwise if they are still hot from the charging the overheating system will not allow the batteries to be used till they cool down properly. Place the batteries in a cool area, like a refrigerator until they cool down sufficiently.

Why does the battery gas gauge show nearly empty after I just finished charging?
The internal printed circuit board sometimes needs to be reset in order for the LCD's to show the proper level of charge within the battery. Check the battery with a voltmeter and you will most likely find that they are at full charge (13VDC). Go ahead and use the battery, you will not damage it. Once the battery has been nearly drained down, let the heat gun run just with the fan motor on, till the battery completely drains, this may take many hours. Once the battery has been completely drained, place it back on the charger and fully charge it. Once the charging is finished you should find that the gas gauge has been reset and is now functioning properly.

How do I adjust the heat of the hot air tool. The temperature is to hot for my application?
The only way to change the temperature is to change the ceramic heating element that is inside the hot air tool to a lower wattage-heating element. Remove the heating element that is in the tool according to the service manual instruction booklet. Then install a lower wattage-heating element. If you need to purchase a lower wattage heating element, contact jonathan [at] malcom.com.

I need to get an on/off switch for my heat gun. Can I get it from you?
The heat gun has been modified during manufacture to be EMI protected and to prevent emissions from the tool. Any attempt to repair/replace the heat gun in the field will corrupt these protective measures. The entire gun has to be replaced. If an element should fail, for whatever reason, the element can be replaced in the normal routine.

I will need to use the tool continuously for two hours. Can I use it for that time?
Yes, if you have spare batteries on hand. The tool at full power will drain off the Batteries in about 25-30 minutes. The charging system will recharge the Batteries in 2 hours. To run constantly, the Batteries would be changed every half hour. While not likely to be required in normal use, some jobs might require this operation. Therefore, eight (8) Batteries would keep the tool operating for an extended period without harm.
