Protection Class I
Danger! Unplug the tool before opening it, as live compo-
nents and connections are exposed.
Incorrect use of hot air tools can present a fire and explosion
hazard, particularly in the proximity of flammable materials
and explosive gases.
The tool must be operated under supervision.
Heat can ignite flammable materials which are not in view.
For personal protection, we strongly recommend the tool to
be connected to an RCCB (Residual Current Circuit Breaker)
before using it on construction sites.
The rated voltage stated on the tool must correspond with
the mains voltage.
Danger of getting burned! Do not touch the heater tube and
nozzle when they are hot. Let the tool cool down. Do not
point the hot air flow in the direction of people or animals.
Protect the tool from damp and wet.

WARNING
CAUTION
Only connect the tool to a receptacle with protective earth
conductor. Any disconnection of the protective earth
conductor, in or outside the tool is dangerous!
Only use extension lead with protective earth conductor.

OPERATION LEISTER Unifloor E
Operational condition: Accessories
• If the welding rod de-reeler (24) and lifting device (26) are available:
– Attach welding rod de-reeler (24) to the Unifloor E tool using cheese
head screw M8
× 20 (25).
– Attach lifting device (26) to the tool using socket head cap screw M6
× 30 (27).
Operating condition
• Check the nozzle setting: the nozzle must be positioned at a distance of about 2 -
3 mm from the floor cover and welding rod.
• When welding linoleum, lower the cover (28) on to the welding nozzle (4) (see
Detail A).
• Automatic drive
Automatic drive is adjusted as required, depending on nozzle position, by
means of switch pin (22) and set screw (23).
• Connect tool to the mains. Mains voltage must correspond with the voltage
rating stated on the tool.
• Switch on tool using main switch (14). Hot air blower (3) starts automatically.
• Important: under voltage
If the maximum temperature is not reached, reduce the airflow by means of
the manual air vane (11) and potentiometer for air flow (17).

Welding procedure
• Swivel hot air blower (3) up to the stop using swivel lever (19). The welding process
starts automatically via automatic drive.
• If necessary, the tool can be started manually by means of the drive switch (15).
• Check the welding process: – Guide roller (21) must run in the joint.
– The welding bead must be visible. Adjust welding
parameters using the potentiometers (16), (17)
and (18) if necessary.
• Wall switch-off (9)
When contact with the wall, is made drive and heater are switched off automati-
cally.
• After finishing welding swing up the hot air blower (3) to the stop using swivel lever
(19). The welding process stops automatically.
• After completing welding work, set potentiometer for air temperature (18) to zero
so that hot air blower (3) cools down.
• Switch off the tool at the main switch (14).
• Disconnect the tool from the mains.
Tool positioning
• Swivel hot air blower (3), using swivel lever (19) up to the stop.
• Operate lifting device (26) by means of lifting device lever (13) so that welding rod
pressure roller (6) and drive roller (7) are at no-load.
• Position automatic welding machine over the joint to be welded.
• Insert welding rod through welding rod guide tube (20) and pull under the welding
rod pressure roller (6) and place it in the joint.
• The guide roller (21) must run in the welding joint.
• Activate lifting device (26) by means of lifting device lever (13) so that the auto-
matic welding machine is ready to start.
Welding parameters
• Set potentiometer for welding speed (16) to required value.
• Set potentiometer for air flow (17) to required value.
• Set potentiometer for air temperature (18) to required value.
• The pressure derives from the actual weight of the automatic hot air welding
machine.
