MAINTENANCE
WARNING:
When servicing, use only identical Ryobi replacement
parts. Use of any other part may create a hazard or
cause product damage.
CLEANING BASE ASSEMBLY
See Figures 23-25.
After extended use, wood particles and resin may build up
inside the base assembly of your biscuit joiner and clog the
path for wood particles going through dust exhaust opening.
Wood particles packing up in this area makes cutting biscuit
slots more difficult.

accidental starting causing possible serious personal injury.
■ Place your biscuit joiner upside down on a workbench and
