4.4 Installing Blades
See Graphic: wc_gr004417
There are two types of blades available for the trowels. Float pans are
large “pizza pan” style blades, which hook on over finish blades. Float
blades are used in the earliest stages of work, and are not pitched.
Finish blades are used in the final stages of working, and are
progressively pitched to burnish the concrete.
Note: Trowel blades must NOT be interchanged, i.e., do NOT put
larger diameter blades on a smaller diameter trowel.
4.4.1 Secure blades to trowel arms with screws (b). Dip threads of screws in
grease prior to installation. This will prevent concrete from cementing
the screws in place and will make removal of the blades easier later on.
4.4.2 Plug the remaining threaded holes in the blade brace with plastic plugs
(c) to prevent them from filling with concrete.
Do not lift the trowel overhead with a float pan attached, as the pan
could fall off and strike personnel working in the vicinity.
