In particular, the user shall ensure that
- the gun is in working order
- the required personal protective equipment (protective gloves) for the operating personnel is available
and used
- the entire operating instructions are in legible condition and available to the operator
- only sufficiently qualified and authorized personnel operates and maintains the gun
- this personnel is regularly instructed in the applicable aspects of operational safety and environmental
protection, and knows the operating instructions and, in particular, the safety instructions.
Make the information available:
This operating manual shall be kept on the site of operation. It must be ensured that all persons operating
the gun can look into the manual at any time. In addition to the operating manual, the instructions pursuant to
the Factory Act and the regulations as regards the use of equipment shall always be at the operator’s
disposal.
Meaning of the Various Safety Symbols
This operating manual shall give concrete advice as to safety to draw the user’s attention to remaining un-
avoidable hazards. These hazards imply dangers to
•persons
•product and equipment
The symbols used in the operation manual shall, in particular, call attention to the safety instructions!
This symbol indicates that there is, above all, danger to persons, but also to
equipment and material.
Caution: Hot surface!
Accident Prevention Regulations VBG 125 - W26
Hot surfaces such as machine parts, tanks or materials, but also hot liquids cannot
always be perceived. The utmost caution is advised when this symbol is attached
to a component.
Always wear protective gloves when you have to touch hot surfaces!

Art.Nr.9119 6
Safety Measures in Case of Normal Operation
The instrument must only be used by persons trained and instructed and being allowed to use it. They have
to know the operating instructions and be able to work accordingly.
Prior to each use, check the gun for visible damage and make sure that it is in perfect condition!
Advise detected defects to your superior at once!
Safety Instructions for the Use of the Hot-Melt Glue Gun MS 150
•Always follow the accident prevention regulation VBG 81 - Processing of Glues issued by the
Professional Association of the Chemical Industry
•Fill gun only just under the charging hole.
•All visible material parts may warm up to 250 °C !
•Never exceed working temperature of the hot melt.
Overheating may lead to decomposition which may affect health.
•Never start working without having mounted a nozzle.
•Do not direct glue jet towards people.
•Prior to any nozzle replacement, unplug connecting cable.
•When a nozzle is replaced, liquid glue may leak out. Warning: Risk of burning!
•Never bring the hot nozzle in contact with the cable.
•Ensure sufficient ventilation.
•Do not inhale vapour escaping from the glue. Attention: inhaling this vapour may cause
irritations of the respiratory tract.
•When your skin got into contact with hot glue, cool it with cold water immediately.
Do not try to remove hot melt from the skin first. If necessary consult your doctor.
•When hot adhesive got into your eyes, immediately cool them under running water for
about 15 minutes and consult your doctor at once!
•Never work without protective gloves and glasses!
•Never fill in any solvents or paraffines to avoid risk of explosion.
Note: - Do not lay gun on its side
- Never overcharge gun
- Press trigger only when gun is heated
- Before you change the glue type, pump residual quantity out of the nozzle
- Do not direct glue jet towards people
- Do not carry out overhead work
- Do not hold nozzle top upward
- Never work without having mounted a nozzle
- Stop using the gun, if casing is damaged due to shock, breakage or heavy wear.

Art.Nr.9119 7
Start-up and Operation
To avoid risk of stumbling:
Lay all instrument connections (cable, hoses, and lines) so that they do not cause any risk of stumbling
(cable conduits, bridges)!
Operation of the Glue Gun
Plug connecting cable of MS 150 Glue Gun into socket with earthing contact.
Adjust working temperature requested. The temperature of the MS 150 Glue Gun is infinitely adjustable bet-
ween approx. 70 and approx. 190 °C. For this, set rotary button to the requested position:
4 @approx. 70 °C 10 @approx. 160 °C
6 @approx. 100 °C 12 @approx. 190 °C
Minor leaking during the heat-up phase is due to hot melt expanding in the nozzle/heating chamber.
Warning: Once the gun has warmed up, nozzle and cover are extremely hot!
Never work without wearing protective gloves!
Loading of Glue
- The MS 150 Glue Gun is designed for applying solvent-free hot melts. Never fill the gun with other
materials. The hot-melt glue gun can work with all the types of hot melts that are designed for working
temperatures of up to max. 200 °C.
- As soon as the gun has warmed up (approx. 10 min.), open cover and fill granulate into the gun till it
appears just under the rim of the charging hole.
- Close cover and allow some time for the glue gun to melt the glue (approx. 10 min. depending on type
of glue).
- The quantity to be applied can be determined by pressing the trigger: the longer you press, the more
glue comes out.
The cover must only be opened when the gun has warmed up!
Application of Hot Melts
Only start glueing, when the glue has properly molten.
Make yourself familiar with the instrument first. Apply a little glue in varying forms (small, large dots) on a
piece of paper or cardboard. This is very easy.
Observe the correct working temperatures of the individual hot melts.
Never start working without having mounted a nozzle!
Press the trigger only when gun has warmed up!

Art.Nr.9119 8
Nozzle Replacement
Only replace nozzles when the glue gun is warm (instrument temperature 60 - 80 °C) and empty. You are
advised to wear protective gloves.
Prior to exchanging nozzles, unplug connecting cable!
Replacing a cold nozzle may damage the gun. If the nozzle is replaced when it is too hot, liquid adhesive
may leak out.
Attention: Risk of burning!
- When your skin got into contact with hot glue, cool it immediately with cold water.
- Do not try to remove hot melt from the skin first. If necessary, consult your doctor.
- When hot adhesive got into your eyes, immediately cool them under running water for about 15 minutes.
Consult your doctor at once!
Never start working without having mounted a nozzle!
Do not direct glue jet towards people!

Art.Nr.9119 9
Operation
The glue gun shall only be used/applied according to its intended use. Please see Section “General Safety
Instructions“.
Improper use of the gun may cause personal injury or material damage.
Non-observance of the safety instructions when working with the gun may lead to serious burns.
Make a functional test acc. to the following list, before you switch on the glue gun:
Check List
- Is the glue gun connected to 230/120 volts?
- Is the nozzle clean and free of any foreign matters?
- Is solvent-free hot melt in the gun?
- Has the heat-up time of approx. 10 minutes (depending on the glue type) been observed?
While you are working...
...the glue gun must always be deposited on the wire strap.
Never lay gun on its side!
- Open gun only if required; cover can only be opened while gun is warm.
- Keep hot melt free of dirt and humidity.
General Hints
-Do not start glueing before glue is fluid.
-Glues that have not molten completely will not reach the glueing temperature required.
-Not having the required glueing temperature, glues cannot produce optimum glueing results.
-Due to the high viscosity of partly molten glues a lot of manual energy will be needed to dispense them.
-This will cause some essential parts of the gun to wear very fast .
Always deposit glue gun on the wire strap provided for this purpose. Never lay glue gun on its side!

Note: - Do not lay glue gun on its side
- Never overcharge gun
- Do not direct glue jet towards people
- Do not hold nozzle top upwards
- Do not carry out overhead work
- Never exceed working temperature of the glue
- Stop using the gun, if casing is damaged due to shock, breakage or heavy wear.
Only fill clean and solvent-free glue into the gun. Contaminated glue, nails, clamps, sand, etc. cause mal-
functions. The use of solvents, petrol, benzole, toluol, acetone, terpentine, etc. will lead to an explosion.
Never use these materials!
If you observe the operating instructions, the gun does normally not need cleaning.
If the gun is used very often, it has to be maintained regularly. To set a date, please call our service depart-
ment.
