WORK EXAMPLE

CAUTION
Parts of the nozzles supplied are sharp, so use gloves
when removing them from the case and when attaching
or detaching them.
Select the nozzle in consideration of the shape of the
article being heated and the area being heated.
1. Peeling off paint (Fig. 6)
Use nozzle (fl at) or nozzle (round) to soften the paint
with the hot wind, and then remove it with the scraper
supplied.
Note that heating the paint too much may result in it
scorching and becoming harder, making it diffi cult to
scrape off .
2. Softening adhesive (Fig. 7)
Use nozzle (fl at) or nozzle (round) to soften the surface
and make it easy to peel, and then pull up one of the
edges, blow heat underneath it and gently peel it off so
that none of the adhesive remains.
3. Heat wrapping (Fig. 8)
Use nozzle (fl at) to heat-wrap shrink fi lm and tubes. The
material will change color or crack if hot air is blown onto
it from a close distance, so maintain an appropriate
distance while monitoring progress.
4. Forming resin pipes (Fig. 9)
Use nozzle (curved surface) to evenly heat the
circumference of the resin pipe.
To prevent the inside of the pipe from narrowing when
bending it, etc., pour sand inside, block both ends and
then gently bend it.
5. Removing putty from window frames (Fig. 10)
Use nozzle (glass protector) to soften the putty with heat,
and then remove the putty with the scraper supplied.
Note that glass may crack if heat is continually applied
to it.
6. Defrosting water pipes (Fig. 11)
Use nozzle (curved surface) to heat the frozen area from
the edge to the center. Do not mistake water pipes for
glass pipes.
Take care to avoid damaging frozen resin areas on
water pipes.

MAINTENANCE AND INSPECTION

1. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, retighten them immediately. Failure to do so
could result in serious hazard.
2. Maintenance of the motor
The motor unit winding is the very "heart" of the power
tool.
Prevent any foreign objects, oil or water from getting
inside the intake.
3. Replacing supply cord
If the replacement of the supply cord is necessary, this
has to be done by Hitachi Authorized Service Center in
order to avoid a safety hazard.
4. Cleaning of the outside
When the tool is stained, wipe with a soft dry cloth or a
cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, as they melt plastics.
