Application

Please read operating instructions carefully before use

and keep for future reference.

Operating Instructions (Translation of the original operating instructions)

GB USA

Danger to life when opening the device as live components and connections are

exposed. Unplug the line/mains plug from the plug socket before opening the device.

Incorrect use of the hot air tool can present a fire and explosion hazard

especially near combustable materials and explosive gases.

The tool must be operated under supervision.

Heat can ignite flammable materials which are not in view.

The device machine may only be used by qualified specialists or under their super-

vision. Children are not authorized to use this device.

For personal protection, we strongly recommend the tool be connected to an

RCCB (Residual Current Circuit Breaker) before using it on construction sites.

Rated voltage stated on the device must correspond to line/mains voltage.

N 61000-3-11; Zmax = 0.105 Ω+ j 0.066 Ω. If necessary, consultate supply

authority.

In the case of line/mains power failure extract hot air blower and set

main switch to position 0

Do not touch hot welding nozzle, they can cause burns. Allow the tool to cool

down. Do not point the hot air flow in direction of people or animals.

Welding temperature

Turn the main switch (3) to I. Set the temperature knob (6) to the

required value. Heating-up time approx. 5 minutes.

Air volume

• To achieve optimum welding of the modified bitumen membrane liners or to

avoid bitumen spatters, the air volume can be set with the turning knob for

air volume (32).

CAUTION: If the quantity of air flow is reduced, the temperature knop (6)

may not be set higher than stage 8.

Risk of overheating the heating element.

Welding speed

Set the appropriate welding speed with the speed knob (5) depending

on the sealing sheeting and weather conditions.

Joining force

• The joining force is transmitted to the drive roller (13).

• The replacement drive roller (22) and the screw-on additional weight (23)

can be removed as required (see joining

force table).

•

Before putting into operation, check

power supply cord

(1) and connector as well as extension cable for electrical

and mechanical damage.

• Move lower guide bar (15) into the required position using clamping screw, lower guide bar (17) and

upper guide bar (33) using clamping lever, upper guide bar (16)

• Clip strain relief of power supply cord (1) in holder (18)

• Check the basic setting of the welding nozzle (7).

– The welding nozzle (7) must lie flat on the lower membrane liners (see Detail A).

– The distance between the centre of the drive roller (13) and the air outlet of the welding nozzle (7)

should be 80 mm (see Detail B). Otherwise the hot air blower (8) must be set with the scale for tool

adjustment (12) by loosening the screws (24).

– The welding nozzle (7) should be set parallel with the drive roller (13

• Transport configuration

– Swivel the guide roller (19) upwards

– Extend the hot air blower (8) by pulling the locking lever (10) and swivelling it up until it locks in place.

• Set the guide roller (19) to the required overlap using the guide roller adjusting screw (20).

• The distance between Guide roller (19) and Drive roller (13) is 5 mm (Detail C).

Operating preparation

•

To achieve an even weld, there must be no bitumen deposits on the drive roller (13).

• In the case of soiling, the following measures can be taken:

– Release screws for scraper (26). Reduce the distance between the scraper (25) and the drive roller (13).

Tighten the screws for scraper (26).

– Release the fastening screw (14), remove and clean the drive roller (13). Mount the drive roller (13). Tigh-

ten the fastening screw (14).

– Release the fastening screw (14) and remove the drive roller (13). Release the Screw-on additional

weight (23), remove the replacement drive roller (22) from the holder (27). Mount the replacement

drive roller (22) with the fastening screw (14). Place the soiled drive roller (13) into the holder (27)

and secure with the Screw-on additional weight (23).

• Connect tool to rated voltage.

Power supply

If an extension cable is used, a 3 ×4 mm2mains cable must be used. The extension cable must be approved for

the application site (e.g. outdoors) and labelled accordingly.

Tool positioning without lifting device

•Lift hot air welder applying pressure onto upper guide bar (33) and move to weld position

• Swivel the guide roller (19) downwards.

• The distance between Guide roller (19) and Drive roller (13) is 5 mm (Detail C).

• Set the welding parameters, see Page 19.

•

The welding temperature must be attained (heating-up time approx. 5 minutes).

• Perform a test welding according to the welding instructions of the material manufacturer and the

national standards or guidelines. Approve the test welding.

• Raise the locking lever (10), lower the hot air blower (8) and move it in between the overlapping

membrane liners to the end stop. Wait a moment until the material is plasticized.

• Start the drive with the drive switch (4). In case of mains power failure, the drive switch (4) switches

off automatically. Once mains power is restored the drive can be restarted.

• The hot air welder is guided along the overlap at the upper guide bar (33).

Do not apply any pressure to

the upper guide bar (33);

this could lead to welding errors. Observe the position of the guide roller (19).

• After welding pull locking lever (10), move out hot air blower (8) as far as the end stop and swivel up

to the latching point, at the same time switch off drive switch (4).

• On completion of welding work, set the temperature knob (6) to zero; this cools the welding

nozzle (7).

• Set the main switch (3) to 0.

•

In the case of line/mains power failure extract hot air blower (8) and set main switch (3) to

position 0

• Disconnect power supply cord (1) form the line/mains.
