OPERATION
NOTE: Before using the tool, read the
instruction book carefully.
BEFORE USING THE TOOL
Before starting the job it is advisable to test the
workpiece for the ideal temperature to use. The
description below gives an indication of the likely
heat settings required but always start with the
low heat setting.
The distance between the nozzle and the
workpiece will vary according to the material being
worked on but this should always be at least
50mm (2inch) or more on either heat setting.
All applications, with the exception of removing
paint from the window frames, can be performed
without using a nozzle; however for best results
nozzles are recommended.
PUTTING INTO OPERATION
1. SWITCHING ON/OFF
Switching on:
To put into operation, slide the switch (5) to
position 1, 2 or 3.
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 =25 C 150L/min

2 =350 C 300L/min

3= 550 C 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
28
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
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
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
This nozzle
deflects the heat
away from glass or
other fragile areas
and back onto the
workpiece.
4) Hook Nozzle
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.
