Troubleshooting
Replace PCBA in the handle.
Measure the resistance between any
two of the three cables in the motor
and ducted assembly by using a
multimeter.
If the resistance is infinite, replace
the motor and duct assembly.
Press the boost button/air
velocity adjusting knob when the
blower runs, the air velocity and
the volume doesn’t change.
Replace PCBA in the handle.
The air velocity and the volume
are decreased compared with
normal use.
The fan in the duct is
over-worn
Open the handle housing , take off
the fan baffle and check the fan. If
the fan is over-worn, replace the
motor and duct assembly.
