Important Caution:
1． Before use the glue gun, check if the plug cord into electrical outlet properly;
2． When glue gun in first use, the heating element will have small smoke, it is normal situation, but the smoke will disappeared after 10 minutes;
3． After power, not for a long time in standby mode(not longer for 20 minutes), when the suspension of use, unplug first.
4． Avoid to use the glue gun under very hot or very cold environments.
5． Better not work under direct cold wind blowing, it will reduce efficiency and loss power
6． When in continuous using, do not press the trigger with great pressure, and try to squeeze out the un-melted glue, it would damage the glue gun
7． Not applicable for bonding heavy objects or objects needed strong adhesive
8． The quality of glue stick will directly influence the glue gun function and sticking objects quality;
9． If the power cord is damaged, do not replace it by yourself, must ask for professionals to replace it.
10． This tools must b e placed in its position when not in use. And storage before the tools complete cooled.
11． Be careful when using any other electrical appliance with flammable material.
12． Not applicable for a long time in the same place.
13． Do not use an explosive gas atmospheres.
14． Note that heat may be the line of sigh, combustible materials.
15． Do not leave equipment unattended when switched on.
16． This appliance is not intended for use by persons(including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
17. Children should be supervised to ensure that they do not play with the appliance.
Using methods
1. Glue gun using voltage is 110-220V AC,50/60Hz;
2. Tip gun forward on stand and place a piece of cardboard under the nozzle
3. Use 7-8mm (mini trigger glue gun), 11-12(big trigger glue gun), insert glue sticks through
4. After power, wait for 5-10 minutes to allow glue to soften

test instrument
When the (100±2)V DC voltage is applied, the resistance can be measured to ±2.5% accuracy.
Internal electrode
It consists of stainless steel beads with a total mass of 4KG and a diameter of 5mm. Steel balls should take measures to prevent or remove oxidation of steel balls and copper plates, because oxidation may affect their electrical conductivity.
External electrode
It consists of a copper contact plate and is cleaned with ethanol before use.
Device for measuring conductive coating resistance
Consisting of three conductive metal probes, the probe has a radius of (3 ± 0.2) mm and is mounted on a base plate. The two probes are separated by (45 ± 2) MM and connected by a metal strip. The third probe is separated from the midpoint of the other two probe wires by (180 ± 5) MM and insulated from them
Sample preparation
If the shoe is equipped with an activity mat, it should be retained when testing. Clean the sole surface with alcohol to remove all traces of release agent and rinse with distilled water
Dry at (23±2)°C. The sole surface should not be rubbed or worn, nor should it be cleaned with organic materials that damage the sole or expand the sole.
Special preparation of wet conditioning
For the specimens adjusted under wet conditions, a conductive coating with an area of ​​200 mm x 50 mm was coated on the sole of the shoe, and the coated surface included the heel and the forefoot of the shoe. Dry measuring coating resistance value is less than 1 x 103 megohms
The shoe is filled with clean balls and placed on the device's metal probe so that the forefoot area of ​​the outsole is supported by two probes spaced 45 mm apart. The heel area is supported by the third probe and the probe is measured with a test instrument. The resistance value between the third probe and the probe.
According to the function of the tested shoe, adjust the prepared sample according to one of the following conditions.
1) Dry conditions, (20 ± 2) °C, relative humidity (30 ± 5)%. (Placed for 7 days)
2) Wet conditions, (20 ± 2) °C, relative humidity (85 ± 5)%. (Placed for 7 days)
If the test cannot be performed in a regulated environment, the test should be fully tested within 5 minutes after the sample is removed from the environment.
Test procedure
Fill the sample with a clean ball with a total mass of 4 KG. If necessary, use an insulating material to increase the height of the upper. Place a sample of the filled steel ball on a copper plate and apply a (100 ± 2) V DC test voltage between the steel plate and the steel ball for 1 minute and calculate the resistance value.
The energy consumption of the sole of the safety shoe should not exceed 3 W. If the withstand voltage is reduced due to consideration of the 3 W limit, the actual voltage value should be recorded on the test report.
