removing paint or lacquer from larger flat surfaces such
as skirting boards doors, stairs etc. It should be used in
conjunction with a flat scraper.

APPLICATION EXAMPLES

Removing paint and lacquer (Fig. 3)
Hold the gun with the nozzle (11) approximately 50 mm
from the surface of the paintwork and start at the lower
heat setting to move it slowly backwards and forwards
until the paint blisters and bubbles. Keep a 30° to 40°
angle between the tool and the workpiece. Immediately
remove the paint with the scraper (12) or putty knife,
otherwise the paint will harden again. To avoid ignition
clean immediately the paint and the particles from the
tool. Whenever possible strip the paint along the wood
fibres. Aim to heat the paint just ahead of the scraper so
that you can achieve continuous action. Do not heat the
painted surface for too long, as the paint will burn making
it more difficult to remove.
Most stickers can also be removed from paintwork by
using the heat to soften the adhesive. Be careful not to
direct the heat for too long if you are trying just to remove
the stickers, as this will blister the underlying paint.
WARNING: Be careful when removing layers
of paint in old buildings; in the past the buildings may
have been painted with paint containing lead, which is
highly toxic. Exposure to even low levels of lead can
cause serious brain and nervous system damage;
young and unborn children are particularly vulnerable.
In the presence of such paint do not use the hot air gun
but consult a specialist.
Removing paint and lacquer from window frames
(Fig. 4)
When stripping paint from window frames always use the
glass protection nozzle (9). Ensure you have the nozzle
facing the correct way to deflect the heat away from the
glass before you turn the switch (6) on. Rotate the gun
or nozzle 90o as you move from horizontal to vertical
surfaces. Allow nozzle to cool down before attempting
to turn it. Paint can be removed from profile surfaces by
using the scraper (12) and/or a soft wire brush.
WARNING: Glass is a fragile material and can
break easily.
WARNING: Do not strip metal window
frames, as the heat may be conducted onto the glass
and crack it.
Defrosting water pipes (Fig. 5)
Choose the reflector nozzle (10).
Always heat the pipe from the end of the frozen portion
towards the middle.
Warm plastic pipes as well as connections between pipe
pieces especially carefully to prevent damage.

WARNING: Water lines often do not differ in
appearance from gas lines. Gas lines are not to be
heated under any circumstances - danger of explo-
sion.
Welding plastic tubes (Fig. 6)
Choose the reduction (8) or reflector (10) nozzle.
The materials being welded together must be of exactly
the same type of plastic.
The areas being welded must be clean and grease-free.
Heat one of the tubes in the joint until the material
becomes tacky, and then apply the other tube.
Please note that plastics can very quickly change from
being tacky into becoming liquid.
Shrink fitting (Fig. 7)
Choose the reflector (10) or reduction (8) nozzle.
Select a heat-shrinkable tube with diameter, appropriate
for the workpiece (for example, a cable shoe).
Heat the heat-shrinkable sleeve evenly.
Bending plastic tubes (Fig. 8)
Choose the reflector nozzle (10).
Set the machine down on its rear in an upright position
with the nozzle pointing upwards.
To avoid buckling or kinking the tube, fill the tube with dry
sand and seal at both ends.
Heat the tube evenly by moving from side to side and
bend it to the required shape.

Maintenance

WARNING: Always ensure that the tool is
switched off and unplugged before attempting to per-
form inspection or maintenance.
Regularly inspect all fasteners and ensure they are
properly tightened.
CLEANING
For safe operation always keep the machine and its
ventilation slots clean.
Regularly check to see if any dust or foreign matter has
entered the grills near the motor and around the switch.
Use a soft brush to remove any accumulated dust. Wear
safety glasses to protect your eyes whilst cleaning.
If the body of the tool needs cleaning, wipe it with a soft
damp cloth. A mild detergent can be used.
WARNING: Never use alcohol, petrol or other
cleaning agent. Never use caustic agents to clean
plastic parts.
WARNING: Water must never come into con-
tact with the tool.
