4. Operation

4.1 Application

This trowel is a modern, high production machine intended for floating and finishing freshly
poured concrete slabs. The machine's good balance, adjustable handle, and easily reached
controls add to operator comfort and productivity. An automatic stop sensor provides added
operator safety. Finishing rates will depend on operator skill and job conditions.
DO NOT use this machine for any application other than troweling concrete.

4.2 New Machine Set-up

Trowels are shipped from the factory with the handle removed. Follow instructions on
Installing Blades and Installing and Adjusting Handles when setting up new machines or
when installing new handles and blades.

4.3 Recommended Fuel

The engine requires regular grade unleaded gasoline. Use only fresh, clean gasoline.
Gasoline containing water or dirt will damage fuel system. Consult engine owner's manual
for complete fuel specifications.

4.4 Installing Blades

See Graphic 2
There are four types of blades available for the trowels. Float pans are large "pizza pan" style
blades, which hook on over finish or combination blades and are available for the 36"
machines only. Float blades are available for all machines and clip on over finish or
combination blades. Both 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.
Combination blades can be used throughout the concrete working process. They are used in
place of float blades or pans and finish blades.
Note: Trowel blades must NOT be interchanged, i.e., do NOT put larger diameter blades
on a smaller diameter trowel.
4.4.1 Finish blades are flat on both edges and can be installed in either direction.
When installing combination blades, orient blades as shown (a). This position the raised
edges of the blade correctly for the clockwise rotation of the machine.
4.4.2 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.
4.4.3 Plug the remaining threaded holes in the blade brace with plastic plugs (c) to prevent
them from filling with concrete.
