Speedheater Cobra, Instruction & Safety Manual

• Use a profile scraper on contoured window
surfaces.
• To remove glazing putty, place the shroud
on the surface of the glass and heat the
putty until it’s soft enough to be carved away
with a chisel (
Fig 9 ). Old, rock-hard putty
may require two or more passes along each
section of the window before it’s soft enough
to be easily peeled off.
Shutting Down
When work is complete, move the switch to the
OFF position and unplug the cord. Place the Co-
bra upside down and allow the IR-tubes to cool
before it’s packed away. Never leave the tool
unattended until it has completely cooled.
Tips & Techniques
• For best results use high-quality pull-type
scrapers, and sharpen the blades as soon
as they begin to dull.
• Scraper blades are available in a variety
of shapes. Choose one that most closely
matches the painted surface.
• A copycat and rotary grinding tool can be
used to modify scraper blades to remove
paint from uncommon profiles.
• For best results plan on making two passes
over each surface. The first pass removes
the bulk of the paint; the second one pass
gets the last of the debris that was left be-
hind and leaves a smooth, almost spotless
surface that simply needs a light sanding
prior to priming and painting.
• To make old, dried out old paint ore water
baist paint more responsive to the effects
of infrared radiation, pre-treat the painted
surface with Speedheater Accelerator Oil,
or raw linced oil. Brush or spray on a light
coating at least one hour before heating.
Accessories
A variety of scrapers and other accessories are
available to lessen the drudgery of removing old
paint and glazing. More information about these
products is available on the web site.
