NOTICE:
If the shear blades do not move

or repairs.
Removing or installing the chip
receiver
CAUTION:
When installing or removing the
chip receiver, always wear gloves so that your
hands do not directly contact the shear blades.
The chip receiver gathers discarded leaves and makes
clean-up afterward much easier.
To remove the chip receiver, remove three screws (for
DUH504S), four screws (for DUH604S) or five screws
(for DUH754S), and then remove the chip receiver from
the tool. To install the chip receiver, follow the removal
procedure in reverse.
