SWITCHING OFF:
To switch off, slide the on/off switch (5) to the stop at
position 0.
After working for a longer time with high temperature, allow
the unit to cool by running in the cold air setting 1 before
switching off.
2. THERMO-PROTECTION SWITCH-OFF
When the heater is overloaded (e.g. as a result of restricted
air flow), the unit switches it off automatically, however,
the blower continues to run. When the unit has cooled to
operating temperature, the heater is switched on again.
3. SETTING THE AIR FLOW AND
TEMPERATURE
The switch (5) can be set to three blower steps. Suitable
air flow and temperature combinations can be selected
according to the applications.
1 =40
℃ ，
300L/MIN
2 =350

3= 550

500L/MIN
The cold air setting 1 is suitable for cooling a warmed work
piece or for the drying of paint. It is also suitable for cooling
the unit before placing down or the changing of nozzles.
The air setting 2 is suitable for Bending Plastic and heating
shrinking plastic.
The air setting 3 is suitable for stripping paint and defrosting
pipes.
4. NOZZLES
The kit is supplied with 4 different shaped nozzles, which
can be used as follows:
1) CONCENTRATION NOZZLE
（
SEE FIG.A
）
This nozzle directs a concentrated heat flow to the
workpiece. It is ideal for use when removing paint in
awkward corners, crevices, mouldings, beading, architraves
or whenever precise paint removal is required.
2) FLAT NOZZLE
（
SEE FIG.B
）
This nozzle directs a long narrow heat pattern to the
workpiece, and is ideal for removing paint or varnish from
large flat surfaces such as skirting boards, doors, stairs etc.
It should be used in conjunction with a flat scraper. Vinyl
tiles can be removed by softening the tile and adhesive.
3) GLASS PROTECTION NOZZLE
（
SEE
FIG.C
）
This nozzle deflects the heat away from glass or other
fragile areas and back onto the workpiece.
4
）
HOOK NOZZLE
（
SEE FIG.D
）
This nozzle disperses the heat flow evenly around the whole
workpiece. It is ideal for defrosting frozen pipes, soldering
pipe work, bending plastics and heat-shrinking electrical
parts.
5) SHAVE HOOK
（
SEE FIG.E
）
Take the handle from the set, remove the nut from the end,
and fit the triangle blade in place by refitting and tightening
the nut. The triangular shave hook is ideal for stripping paint
from flat wooden surface and edges.
Remember to clean the blade after use with wire wool and
lightly oil before storing.
5. REMOVING PAINT
Choose the required nozzle and fit onto the heat outlet.
Select the scraper or shave hook required. Hold the gun
with the nozzle approximately 50mm (2inch) from the
surface of the paintwork and start with the lower heat
setting move it slowly backwards and forwards until the
paint blisters and bubbles. Immediately remove the paint
with the scraper or shave hook. Aim to heat the paint just
ahead of the scraper so that you can develop a continuous
action. Do not heat the paint for too long, as this will burn
the paint making it 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 paint.
6. REMOVING PAINT FROM WINDOW
FRAMES
Always use the glass protection nozzle. Ensure you have the
nozzle facing the correct way to deflect the heat away from
the glass before you switch on. Rotate the gun or nozzle
900 as you move to horizontal or vertical bead. Allow nozzle
to cool before attempting to turn it. Paint can be removed
from profile surfaces by using a shave hook and/or a soft
wire brush.
WARNING: Glass can break easily.
7. DEFROSTING FROZEN PIPES
Choose the Hook nozzle and fit over the heat outlet. Always
heat from one or other end of the frozen portion, not from
the middle.
WARNING: Do not attempt to defrost PVC pipes. Always
check that it is a water pipe and not a gas pipe. Do not heat
a gas pipe.
8. SHRINK SEATING ELECTRICAL CABLES
Choose the Hook nozzle and fit over heat outlet. Select a
heat-shrinkable sleeve with a diameter matching that of the
workpiece. Evenly heat the sleeve.
