Air supply
• Leister blowers must be used for the air supply (pay attention to the direction of rotation and the electrical connection).
• For use in a dusty environment the tool should be fitted with a Leister stainless steel filter on the air intake connection. Where
a particularly critical dust problem exists (eg metal, electrically charged or damp dust) special filters must be used to avoid
short circuiting the tool.
• The hot air tool should only be supplied with air up to a max. 50ºC.
• The minimum air flow must be observed (technical data, page 11).
Attention: always operate device with air supply !
Operation
• Connect tool to the mains.
• The power supply cord should have the corresponding cross section area of conductor and should be fitted by a specialist.
Danger of death when opening the device, as live parts and connections are exposed. The device
must be fully disconnected from the mains before opening it.
• As required, push-fit appropriate nozzle or reflector.
Danger – can cause burns! Do not touch the heating element tube and nozzle while they are hot.
Allow the device to cool. Do not direct hot-air jet towards people or animals.
•
LE 3000
– Adjust the hot air temperature via the
potentiometer (5).
– As required, reduce the air flow with the
air regulating knob (4).
•
LE 5000
– Adjust the hot air temperature via the
potentiometer (5).
• Make sure that the hot air can flow freely (fire hazard).
Danger of fire and explosion if air heaters are installed and used incorrectly, especially in the
vicinity of flammable materials and explosive gases.
• The Leister Company, as well as the authorized Sales and Service Centres, offer advice and an introduction to the areas of
application of hot air tools, free of charge.
• After use, allow the tool to cool down by letting cold air flow through it (preventing warm air back pressure).
CAUTION:
• The mains connection should have a suitable
double pole isolator
with a
3 mm distance between contacts.
Accessories
• Only Leister accessories should be used.
• Accessories at www.leister.com
Let the tool cool down before changing the nozzle or reflector.
• Temperature control by additional Leister cascade controller (should only be fitted and adjusted by the Leister Company).

should be fixed by using
four M5 screws
on the
installation stand (7).
• When installing the tool, ensure that:
– only cold air is sucked in
– no (warm air) back pressure develops
– the device is not subject to jets of hot air from another device.
• Protect the tool from vibration and shock.
• Installation dimensions, page 3 (Size).
