Danger to life!

Danger to life when opening up the tool, as live components and
connections are exposed. Before opening the tool, unplug from the
mains supply. Electrically conducting material (e.g. PE-EL) must not
be welded.

Fire and explosion hazard with incorrect use of the hand extruder
(e.g. overheating of the material), especially near combustible
materials and explosive gases.

The tool must be operated under supervision.
Heat can ignite flammable materials which are not in view.
The machine may only be used by qualified specialists or under
their supervision. Children are not authorized to use this machine.

For personal protection on building sites we strongly recommend
the tool to be connected to a RCCB (Residual Current Circuit
Breaker).

The voltage rating stated on the name plate of the tool must
correspond to the mains voltage.
In case of a power outage, the main switch and the drive must be
switched off (loosen lock).

Danger of getting burned! Do not touch exposed metal parts
and escaping plastizised material. Do not point the hot air flow
and escaping plastizised material in the direction of people or
animals.

Protect tool from dampness and wet.

Warning

Caution

Connect the tool to a mains socket with protective earth.
Every interruption of the protective earth inside or outside of the
tool is dangerous!

Only use extension cables with protective earth!

Operating

Working environment / safety

When interrupting the welding, the drive is to be
switched off with the drive on/off switch (2).
With the handle properly adjusted and firmly tightened,
place down the manual extruder on a stable and
fire-proof surface as shown in the figure.

The hand extruder must not be used in inflammable environments or where
explosion hazards exist. Ensure stable positioning during operation. The
connection cable and the welding rod must remain unimpeded and must not
hinder the user or others during operation.

Rest the hand extruder on a fireproof surface! Hot metal parts and the hot-air jet
must have sufficient clearance from the surface and walls.

Handle Adjustment

1. Loosen the clamping by turning the handle (6) in

counterclockwise direction.

2. Adjust handle (6) to the requested working position.

3. Tighten handle clamping again by turning handle (6)

in clockwise direction.

Workplace

For starting operation of and placing down the hand
extruder, Leister offers a universal device stand.

Operating

Power supply

When using an extension cable, take care to ensure the minimal cable cross-section:

Extension cables must be approved for the working environment (e.g. outdoors) and labelled
accordingly.

If a generator is used to supply electricity, the rated power of the generator must be 2x the
rated power of the hand extruder.

After switching on the main switch (1), the device directly heats up to the last adjusted set
values. When the set values are reached, a counter in the status indication counts back from
220 seconds to zero. Once this starting procedure has elapsed, the device is ready for welding
(status: Ready*). The operating temperature of the manual extruder is reached after approx.
5 minutes.
After a short-term mains break, the starting procedure is not repeated.
