Installing or removing the chip receiver
Optional accessory
CAUTION:
When installing or removing the
chip receiver, always wear gloves and attach the
blade cover so that your hands and face do not
directly contact the blade.
The chip receiver gathers discarded leaves and makes
clean-up afterward much easier. It can be installed on
either side of the tool.
To install the chip receiver, press it against the shear
blades so that the hooks fit into the holes of the shear
blades.

To remove the chip receiver, press the levers on both
sides to release the hooks.
