then gently bend it.
5. Removing putty from window frames (Fig. 10)
Use nozzle (glass protector) to soften the putty with heat,

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

could result in serious hazard.
2. Maintenance of the motor

tool.
Prevent any foreign objects, oil or water from getting
inside the intake.

has to be done by Hitachi Authorized Service Center in
