power will turn off (the TEMP indicator will flash after the power is turned off).
The air filter should be cleaned every 100 hours of use.

NOTE:

the air filter and soak it in
water, and then wash out the
dust by hand. Be sure to install
the air filter after it has dried.

B Do not use detergent when

washing the air filter.

B If the dust cannot be removed
