POWERBOND

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 de-

tected defects to your superior at once!

Safety Instructions for the Use of Holt-Melt Glue Gun TR 50.4.25

* Fill tank only up to 1.5 cm below upper rim.

* Never exceed operating temperature of the hot melt.

Overheating may lead to decomposition which may affect health.

* Once the gun has warmed up, nozzle and cover are extremely hot!

Compressed air pressure max. 6 bars

* Never start working without having mounted a nozzle.

* Do not direct glue jet towards people.

* Prior to any nozzle replacement, unplug connecting cable.

* When replacing a nozzle, liquid glue might leak out. Warning: Risk of burning!

* Never bring the hot nozzle into contact with the cable.

* When your skin got into contact with hot glue, immediately cool it 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 and consult your doctor at once.

If the vent valve does not audibly de-aerate, hot glue might flow off the sound absorber

after the trigger has been operated.

Always wear protective gloves!

Note: - Do not lay gun on its side

- Fill tank only up to max. 1.5 cm below upper rim

- Gun must de-aerate audibly

- Always de-aerate before lid is opened

- Do not direct glue jet towards people

- Do not hold nozzle top upwards

- Never work without having mounted a nozzle

POWERBOND

Start-up and Operation

To avoid risk of stumbling:

Lay all instrument connections (cables, hoses, and lines) so that they do not cause any risk of stumbling

(cable conduits, bridges)!

Make supply connections and settings

Connect the TR 50.4.25 Glue Gun to the electric mains of 230 V / 110 V and a compressed air line of max.

6 bars.

- Plug connecting cable into socket with earthing contact.

- When the gun has warmed up (approx. 10 min.), check working temperature at the thermometer (no.28).

If necessary, correct temperature at the thermostat (no. 21).

- - to the right (clockwise) = plus

- to the left (anti-clockwise) = minus

Minor leaking during heat-up phase is due to hot melt expanding in the nozzle/heating chamber.

As soon as the working temperature is reached, the hot melt will not leak out anymore.

Warning: Once the gun has warmed up, nozzle and cover are extremely hot!

Never work without wearing protective gloves!

Stand incl. pressure controller and manometer

Precise adjustment of compressed air ensures an exact regulation of the glue quantity to be applied. The

adjusted pressure may be read from the manometer indication.

- Mount compressed air hose between glue gun and stand

- Connect compressed air hose for main connection to the rear side of the stand.

Loading of Glue

- As soon as the gun has warmed up, open cover (no. 11) by turning the star grip (no. 18) to the left. Load

selected glue.

- Fill tank only up to approx. 1.5 cm below upper rim. To close the cover turn grip to the right.

- Allow approx. 3 - 10 minutes, depending on quantity and type of glue, for the gun to melt the glue.The

quantity to be applied can be determined by pressing the trigger (no. 29); the longer you press, the more

glue comes out.

Application of Hot Melts

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. Try to find out the correct quantity and the ideal pattern by

adjusting the pressure controllers at the stand to different pressures.

Observe the correct working temperatures of the individual hot melt.

Never start working without having mounted a nozzle!

POWERBOND

Nozzle Replacement

Only replace nozzles when the glue gun is warm (instrument temperature 60 - 80°C / approx. 140 - 175 °F)

and empty. For the replacement you need a SW 13 open-end spanner. You are advised to wear 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.

Warning: Risk of burning!

- When your skin got into contact with hot glue, immediately cool it with cold water.

- Do not try to remove hot melt from the skin first. If necessary consult your doctor.

- When hot adhesive got in 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!

Working with Stationary Equipment

(in connection with pneumatic foot switch)

To work with stationary equipment mount glue gun and foot switch according to enclosed drawings

„Connection of Foot Switch“ and „Stationary Equipment“. Then, proceed as follows:

-Press trigger (no.29) down to stop and hold it

-Plug enclosed screw into the borehole provided for this purpose at one side of the casing handle

-Let trigger loose

-Trigger is locked

POWERBOND

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

- Did you make sure that compressed air is supplied to the glue gun?

- Is pressure max. 6 bars and min. 2 bars?

- Is the glue gun connected to 230 volts / 110 volts?

- Is the nozzle clean and free of any foreign matters?

- Is hot melt in the premelting tank?

- Has the heat-up time of approx. 10 minutes (depending on the glue type) been observed?

While you are working...

...the glue gun always has to be deposited on its stand or wire strap (unless it is fitted to a balancer).

Never lay gun on its side!

- Open premelting tank only if required.

- Keep hot melt free of dirt and humidity.

When using the stand, remove wire strap!

General Hints

Should the sound absorber (no. 6) got stuck, the adhesive tank may be under pressure. The vent valve

(sound absorber) must audibly de-aerate each time you operate the trigger (no. 29).

Warning: With this, hot glue might come off the sound absorber!

If the vent valve does not de-aerate audibly, the adhesive tank must be de-aerated by unscrewing the

sound absorber (no. 6), the DT - SEV (no. 7) and the swivelling screw (no. 33).

For this, you are advised to wear gloves.

No liquid glue should get into the sound absorber, when the gun is ready for operation.

Always deposit the gun on its stand or use the wire strap or a balancer. When using the stand, remove

wire strap!

If nevertheless, glue should have got into the vent valve, either clean that valve or replace sound absorber,

DT - SEV and swivelling screw.

Never fill the premelting tank up to its upper rim.

POWERBOND

Note: - Do not lay gun on its side

- Fill tank only up to max. 1.5 cm below upper rim

- Gun must de-aerate audibly

- Always de-aerate before lid is opened

- Do not direct glue jet towards people

- Do not hold nozzle top upwards

- Never work without having mounted a nozzle

- Do not carry out overhead work

- Stop using the instrument, if casing is damaged due to shock, breakage or heavy wear.

Even if the gun has been switched off, it may be under pressure and glue might flow out!

When using the stand, remove wire strap!

Cleaning and Maintenance

Only fill clean glue into the premelting tank. Contaminated glue, nails, clamps, sand, etc. cause malfunctions.

If you observe the operating instructions, the gun does normally not need cleaning. The glue remaining in

the gun will remelt when it is warmed up and can be used for glueing again.

The glue must not get too hot, otherwise it may coke (hot melts on a polyamide basis are particularly

sensitive). If this has happened, the gun should be cleaned with REKA cleaning liquid.

If the gun is used very often, it has to be maintained regularly. To set a date, please call our service depart-

ment.
